Miraikan: Stroller friendly?

Yes. You can push a stroller through the museum, and it lends them too — ask a member of staff at the 1F entrance. (The museum never writes 'strollers are fine everywhere' in so many words; what it does is lend them and name exactly one room you cannot take them into.) Every floor from 1 to 7 is served by two elevators, and the museum's own Chinese page describes all its elevators as accessible. The one place strollers cannot go is the Dome Theater on 6F: strollers and large bags are not allowed inside, so leave them at the stroller parking or in a locker before the screening. Staff may also refuse tricycles and similar wheels for the safety of other visitors. Coin lockers are by the entrance to the Symbol Zone on 1F and cost a ¥100 coin that comes back afterwards; anything too big for a locker can be left at the 3F information desk, with no reservations and limited space. (checked 2026-08-11)

Miraikan: Diaper changing table?

Yes. Changing tables are inside the multipurpose toilets on every floor — the museum's Chinese page counts eleven places in the building. The nursing room on 5F has more than a table: each of its two lockable rooms holds a changing bed for lying down, a changing table for standing up and a bin for used diapers. Adult-size changing tables are on 1F and 7F. (checked 2026-08-11)

Miraikan: Nursing space?

Yes. The nursing room is on 5F and men may use it — the museum says so in as many words. It has two lockable private rooms and a shared space. Each private room has a nursing chair, a changing bed for lying down, a changing table for standing up and a diaper bin. The shared space has a nursing sofa, a water dispenser for making up formula and a sink for washing hands. The museum's own family route puts this room on the list of stops, alongside the exhibits. (checked 2026-08-11)

Miraikan: Indoor / outdoor?

Yes. Indoors — a seven-story building. The official floor map puts every exhibition zone, both theaters, the toilets and the nursing room inside, on floors 1 to 7. The only open-air part still on the museum's eating-area list is the 7F courtyard; the terrace beside the observation lounge dropped off that list when the seventh floor went in for refurbishment (checked 2026-09-22). Food trucks park outside on most weekends and holidays. Getting from the station to the door is outdoors, four to fifteen minutes on foot depending on which station you use. (checked 2026-09-22)

Miraikan: Family restroom?

Yes. Wheelchair-accessible toilets sit outside the exhibition rooms on B1 (parking lot), 1F, 3F, 5F, 6F and 7F, with 80 cm doorways that you open by hand; the museum's Chinese page counts eleven multipurpose toilets in the building. Cubicles fitted for ostomates are on 1F (one in the ladies' and one in the unisex toilet, 90 cm doorways), and on 3F and 5F (90-95 cm). Whether the cubicles have a baby seat to strap a child into is not stated on the official pages. (checked 2026-08-11)

Miraikan: Diaper disposal bin?

Yes. Each of the two lockable rooms in the 5F nursing room has its own bin for used diapers. Whether the multipurpose toilets around the building have one is not stated on the official pages. (checked 2026-08-11)

Miraikan: English support?

Yes. Exhibition labels are written in both Japanese and English, with a few exceptions the museum notes itself, and the videos inside the permanent exhibition carry English subtitles. The floor guide comes in Japanese, English, Chinese and Korean, and the website runs in the same four languages. The Dome Theater lends a free English audio guide — ask as you go in, numbers are limited, and it is a straight English track rather than descriptive audio. Scripts in English exist for two of the Geo-Cosmos shows — Into the Diverse World and Digging the Future — kept by the handrail in front of Geo-Cosmos on 3F and lent at the 3F information desk while copies last. Whether staff speak English is not stated. (checked 2026-08-11)

Miraikan: Outside food allowed?

Yes. You may bring your own food and drink, but only to the places the museum lists as eating areas; nothing may be eaten in the exhibition areas or inside any theater. The list, as the museum published it on 2026-09-22: 1F multipurpose room (sometimes taken by groups or events), 1F Symbol Zone (in the marked spots only), 5F lobby (vending machines, an unstaffed cafe stand, nursing room on the same floor), 7F courtyard, 7F Dome Theater lobby, and the 7F conference rooms. Drinks only, no meals: 1F communication lobby and the 7F drinks corner, both with vending machines. The 7F observation lounge and its terrace have dropped off this list while that floor is refurbished. Food trucks park outside on most weekends and holidays. Inside the Dome Theater nothing at all may be eaten, sweets and chewing gum included. (checked 2026-09-22)

Miraikan: Kids' toilet seat & step stool?

Yes. A family media report says the third floor has toilets designed for children, decorated with astronauts and rockets, so a child can use them alone. The official accessibility page lists toilet fittings in detail — ostomate cubicles, adult-size changing tables, urinals with handrails — but says nothing about a child seat or a step stool (checked 11 Aug 2026).. (checked 2026-08-13)

Yes. Two elevators run between 1F and 7F, and one more goes down to the underground parking garage. The ones inside the building measure 180 x 190 cm with a 100 cm-wide, 240 cm-high doorway — wide enough for a side-by-side stroller; the parking-lot elevator is 140 x 135 cm with an 80 cm doorway. They are center-opening, with a voice announcement, braille and handrails on both sides. The museum's Chinese page describes all of its elevators as accessible. (checked 2026-08-11)

Miraikan: Stroller rental?

Yes. Strollers are lent at the 1F entrance — just ask a member of staff, and the FAQ says the same. Do not count on a particular number: the Japanese page says only that numbers are limited, while the English page says thirteen and the Chinese page says four, so treat it as first come, first served. Wheelchairs and power wheelchairs are lent too, and unlike strollers those can be booked: phone any time from a week before your visit up to 17:00 the day before (the day before that if the museum is closed), though numbers are limited and a booking is not guaranteed. Whether either loan costs anything is not stated on the official pages. (checked 2026-08-11)

Miraikan: Steps & slope caution?

Yes. Built to be rolled through. Two elevators run the whole way from 1F to 7F and a third reaches the underground parking garage; wheelchairs, power wheelchairs and strollers are all lent; wheelchair-accessible toilets sit on six levels (parking lot, 1F, 3F, 5F, 6F and 7F, outside the exhibition rooms); four spaces in the parking lot are reserved for wheelchair users; guide, assistance and hearing dogs are welcome; and the museum publishes photo-by-photo wheelchair routes from each of the three nearest stations. The one exception is the Dome Theater on 6F: the seating is tiered, so the museum warns there may be steps as you move to your seat, and strollers cannot come in with you — two wheelchair spaces per screening are provided instead. (checked 2026-08-11)

Miraikan: Nursing rooms?

Yes. One nursing room, on 5F, holding two lockable private rooms and a shared space. Men may use it. (checked 2026-08-11)

Miraikan: Diaper changing tables?

Yes. In the multipurpose toilets on every floor, plus a changing bed and a changing table in each of the two rooms of the 5F nursing room. Adult-size tables are on 1F and 7F. (checked 2026-08-11)

Miraikan: Hot water for formula?

Yes. The shared space in the 5F nursing room has a water dispenser for making up formula. The official pages do not say what temperature it gives. (checked 2026-08-11)

Miraikan: Fathers welcome?

Yes. The museum states plainly that men may use the 5F nursing room. (checked 2026-08-11)

Miraikan: Room privacy?

Yes. Two lockable private rooms inside the 5F nursing room, with a shared space alongside for anyone who does not need a door. (checked 2026-08-11)

Miraikan: Crowding (guide)?

Yes. The museum does not publish a crowding chart; it publishes numbered tickets, which tells you the same thing. The free kids' space runs in 45-minute sittings and hands out numbered tickets on weekends, public holidays and busy days, with the times it starts handing them out printed on the official page — 10:00 for the 11:15 and 12:15 sittings, 12:30 for the 13:15 and 14:15 ones, 14:30 for the 15:15 and 16:15 ones. Only the first sitting at 10:15 needs no ticket; you just turn up. Three of the popular permanent exhibits also need a numbered ticket collected on the day. The Dome Theater is all reserved seating and can sell out. Of the outdoor ticket booth the museum says it can get busy and recommends buying online instead. (checked 2026-08-11)

Miraikan: Stroller access notes?

Yes. Two things to settle before you start pushing. First the stroller: it goes everywhere in the building except the Dome Theater on 6F, so if a screening is on your list, decide now whether to use the stroller park outside the theater, a locker, or a carrier. Second the luggage that rides under the stroller: coin lockers are on 1F, on the left in front of the entrance to the Symbol Zone, and take one ¥100 coin per space that comes back afterwards, in three sizes (large 33 x 42 x 81 cm, 24 of them; medium 33 x 42 x 53 cm, 24; small 33 x 42 x 39 cm, 80). Anything that does not fit goes to the 3F information desk, which takes no reservations and can turn you away when its space is full. Tricycles and similar wheels may be refused at the door for the safety of other visitors. (checked 2026-08-11)

Miraikan

Save

Japan's national museum of emerging science, hands-on throughout.

There is no set route, so the youngest one leads.

MoreWhat kind of place

Miraikan is Japan's national museum of emerging science and innovation, and its permanent exhibition runs in three zones.

The fifth floor explores how the world works at every scale, from space to the environment to living things. The third floor asks what kind of society people want and what ideas would build it.

The third zone has no floor of its own — its pieces sit on floors 1, 3 and 5 — and it ties the planet's systems back to your own life.

The signature piece is a digital globe (Geo-Cosmos), a sphere of screens that loads weather-satellite cloud images every day, so the Earth hanging in front of you carries the day's real weather, and you can see it from floors 1 through 5.

The dome theater on the sixth floor is about 15 meters (roughly 50 feet) across, with a star projector that puts about 10 million stars overhead.

With kidsThe part that matters

The museum says up front that it has no set route, so whatever stops your kid becomes the route.

On the third floor, a free play space (Oya-kko Hiroba) lets children roll objects of every shape and size down a slope of artificial turf — ages 3 and up, with an adult alongside.

That space, the restaurant and the rest areas on floors 1, 5 and 7 all sit outside the ticketed exhibits, so you can get in the door and use all three without buying a ticket.

The play sessions run 45 minutes, and on weekends, holidays and busy days they go by timed ticket handed out that day, so pick one up as you arrive — only the 10:15 a.m. session takes walk-ins.

Check your dates too: the whole building shuts for construction from October 1, 2026 and does not reopen until April 23, 2027.

By age0-1 / 2-3 / 4-6

Ages 0-1The whole museum, floors 1 to 7, is indoors, and the elevators are 180 cm wide by 190 cm deep with a 100 cm doorway — wide enough for a side-by-side stroller. The symbol exhibit, Geo-Cosmos, is a digital globe showing the Earth as it actually is, and the cloud imagery crossing it is data taken in daily from weather satellites. It can be looked up at from anywhere on floors 1 to 5. From the 7th-floor lounge the view runs from Odaiba to Tokyo Tower.There is one nursing room, on 5F, and the museum states plainly that men may use it too. Each of its two lockable private rooms has a nursing chair, a lie-down changing bed, a stand-up changing table and a diaper bin, and the shared area has a water server for making up formula and a hand-washing sink. Changing tables are also in the multipurpose restrooms on each floor. Strollers are lent at the 1F entrance — just ask a staff member. You may bring food in, but it can only be eaten in the rest areas on 1F, 5F and 7F.
Ages 2-3This museum has no set route — its FAQ answers the question by saying there is no particular route and you may view as you like. On 3F, the parent-and-child space Oya-kko Hiroba is free to use and suggested from age 3: Gorogoro-no-Shiba, an artificial-grass slope for rolling down objects of different sizes and shapes, and Koron-Koron-no-Kabe, a wall of holes where you fit rods, hoses and cups into a course and send a ball down it. On the same floor, Hello! Robot lets a child show a paper fan to Keparan, the museum's own partner robot, and watch it dance.Oya-kko Hiroba runs in 45-minute swaps, and on weekends, holidays and busy days you need a same-day numbered ticket (handed out at 10:00, 12:30 and 14:30, first come first served; only the 10:15 session is walk-in). A guardian goes in with the children, up to four children per adult. Eating is not allowed inside the exhibition areas — that happens in the rest areas on 1F, 5F and 7F. If new places are hard for your child, the information desk on 3F lends out comfort items such as ear muffs, sunglasses and lap blankets, and 5F has a Quiet Room with two private rooms, which the museum notes are not soundproofed.
Ages 4-6In Oya-kko Hiroba on 3F, Wunderkammer takes the colouring a child has just done, scans it onto a monitor, and the drawing starts to move; everyone's drawings together build one town. On 5F, Me, Everyone and You is built like a picture book you have stepped inside, moving along as if turning pages. Science communicators are out on the permanent exhibition floors and can be asked questions, and on weekends and holidays they run guided tours of the exhibits.The permanent exhibition is free for preschoolers and 210 yen from elementary school to age 18, and free for under-18s every Saturday. Booking online means a ticket for the preschooler too, priced at zero for the permanent exhibition alone. The Dome Theater on 6F is all reserved seating and must be booked in advance, and the museum warns that the films include blackouts, flashing, abrupt scene changes and loud sound, and that small children and anyone sensitive to light or sound should take care. It is the one place strollers cannot go, and you cannot leave and re-enter partway. Nanairo Quest and Quantum Computer Disco also need a numbered ticket picked up on the spot that day.

By weatherRain, heat, cold

Rainy dayThe permanent exhibition zones, the Dome Theater, and the nursing rooms are all inside one building, floors 1 through 7. The only outdoor spots are the 7th-floor terrace and the courtyard; the walk from the station is 4 to 15 minutes outside.

Before you go

The museum is built around science still in the making, which is what its English name, the National Museum of Emerging Science and Innovation, is getting at. The permanent exhibition runs in three zones: the fifth floor explores how the world works at scales from space to the environment to life; the third floor asks what kind of society people want and what ideas would build it; and a third zone, about our connection to the planet, works from current scientific data and tools. That last one is the odd one out — its pieces (Geo-Cosmos, Geo-Scope, Geo-Prism and the Oval Bridge) are spread across floors 1, 3 and 5 instead of sitting on one floor.source2026-08-11
Asked which way visitors should walk, the official FAQ answers that there is no particular route and you may look in any order. Instead the museum offers six suggested courses, one of them a half-day family course that tells parents to move at the child's pace. It lists eight stops: the parent-and-child play space (Oya-kko Hiroba) on the third floor, the cloud installation (Sky) in the seventh-floor Innovation Hall, the robot gallery (Hello! Robot) and the aging simulator (Aging Park) on the third, an exhibit about the brain and society on the fifth, the fifth-floor nursing room, the eating areas on floors 1, 5 and 7, and the first-floor shop. Which is to say the museum puts a nursing room and a lunch table on the same list as its exhibits.source2026-08-11

More notes (11)

You can get inside without buying anything. The admission page says entry is free for everything other than the permanent exhibition, the dome theater and special exhibitions, naming the restaurants, the parent-and-child play space and the rentable rooms; the online ticket page adds that you may come in as far as the entrances of the exhibition floors with no ticket at all.source2026-08-11
The parent-and-child play space (Oya-kko Hiroba) on the third floor is free, recommended for ages 3 and up, and runs in 45-minute sessions that an adult has to attend with the child, up to four children per adult; the 4:15 p.m. session runs 35 minutes. Inside are three things. A slope of artificial turf for rolling objects that differ in size, shape and material, where you find out how an egg shape travels and what it takes to send something straight. A wall of holes where rods, hoses and cups become a course for a ball, with no single right answer. And a screen that takes in kids' colored-in drawings, sets them moving and builds them into one town.source2026-08-11
The signature exhibit is a digital globe (Geo-Cosmos), described by the museum as the Earth as it actually is, rendered as a digital sphere. The clouds crossing it come from weather-satellite images loaded daily, so the planet you watch keeps changing, and it can be seen from floors 1 through 5. Short programs run through the day: Into the Diverse World, about 5 minutes, at 10:15 a.m., 12:20 p.m. and 4:15 p.m., in English at 1:30 p.m.; Strata of the Future, about 4 minutes, at 11:45 a.m., 1 p.m. and 3:30 p.m., in English at 2:30 p.m.; World Processor, about 6 minutes, at 11 a.m. and 2 p.m.; Earthquakes of the World, about 2 minutes, at 12:45 p.m. and 3 p.m.; and a staff explanation of Geo-Cosmos itself, about 5 minutes, at 10:20 a.m., 1:35 p.m., 3:35 p.m. and 4:20 p.m. All of them, the museum warns, can move or be canceled.source2026-08-11
The sixth-floor dome theater wraps a screen about 15 meters (roughly 50 feet) across in stereoscopic 3D, using two 4K RGB laser projectors, active-shutter glasses and a MEGASTAR-II cosmos projector that throws about 10 million stars. It shows Birthday (3D, about 25 minutes), The Man from the 9th Dimension (3D, about 30 minutes) and a special screening of BLUE OCEAN DOME (about 10 minutes, no narration, recommended for upper elementary age and above). The museum writes its own warning for families: the films go dark, flash, cut hard and get loud, and the curved screen can look distorted or bring on motion sickness, so small children and anyone sensitive to light or sound should think it over. This is also the one room in the building where strollers and large bags cannot come; park them outside the theater or in a locker. Nothing may be eaten in there, candy and gum included, and nobody enters late, leaves early or changes seats. Free English audio guides can be borrowed on the way in while they last.source2026-08-11
For a child who struggles in unfamiliar places, the museum has four things ready. It lends comfort gear at the third-floor information desk, no reservation, limited numbers: ear muffs, sunglasses, a lap blanket, a soft ball. It publishes a photo-and-plain-language visitor guide, in an easy all-hiragana version and a more detailed one, as PDFs or printed at that same desk. It maps every floor for light, sound, smell, crowding and places to sit. And it keeps two quiet rooms on the fifth floor for stepping away from stimulation, though it notes those rooms are not soundproofed. The museum says the first three are for anyone, not only for visitors with developmental differences or sensory sensitivity.source2026-08-11
Science communicators are out on the permanent exhibition floors giving talks and explaining exhibits, and you can stop one with a question; on weekends and holidays they also run guided tours through the galleries. A station on the third floor lets visitors walk the permanent exhibition behind an AI Suitcase, the self-navigating robot developed for blind users, every day the museum is open — you need an exhibition ticket and you sign up on the third floor that day.source2026-08-11
The hands-on core is on the third floor. A robot gallery (Hello! Robot) where various communication robots greet visitors, including the museum's own partner robot Kepalan, which you can show the fan kept there or watch as it dances. An aging simulator (Aging Park) built from mock video games and photo booths that put you inside failing eyes, ears, joints and memory. A look at people living alongside robots (Nanairo Quest), which needs a timed ticket. And a hands-on quantum computing exhibit (Quantum Computer Disco), with a read-aloud mode and Lego models you can compare by touch. The fifth floor adds an exhibit that turns the human brain and its place in society into something like walking through a picture book, page by page.source2026-08-11
The seventh floor is the view floor, with a lounge that looks from Odaiba across to Tokyo Tower and a 278-seat restaurant (CAFETERIA BLUE) whose 39 outdoor deck seats are part of that count. Two newer rooms sit on the same floor: a theater room traveling through space on a large LED panel (timed ticket plus an exhibition ticket), and the Innovation Hall, where an installation called Sky puts you inside clouds drawn from meteorological research as the sky moves from dawn to dusk, with mist and wind added at special times. From September 2026 the restaurant moves to a temporary location while the lounge is renovated.source2026-08-11
Crowding shows up here in the form of timed tickets. The play space switches to them on weekends, holidays and busy days, released at 10 a.m. for the 11:15 a.m. and 12:15 p.m. sessions, at 12:30 p.m. for the 1:15 and 2:15 p.m. sessions and at 2:30 p.m. for the 3:15 and 4:15 p.m. sessions — first come, first served while they last, with only the 10:15 a.m. session open to walk-ins. Inside the permanent exhibition, Nanairo Quest runs on timed tickets and Planetary Crisis and the Quantum Computer Disco on numbered ones. The dome theater is fully assigned seating and can sell out on the day, and the museum recommends booking online because the outdoor ticket booth gets busy.source2026-08-11
ASIMO no longer appears here: asked where the demonstrations are, the official FAQ answers that they ended on March 31, 2022.source2026-08-11
Eating works on a bring-it-and-sit-in-the-right-place basis. The FAQ says you may bring your own food and eat in the rest areas on floors 1, 5 and 7, but not inside the galleries. The seventh floor has the view lounge, the terrace and courtyard when they are open, the dome theater lobby and a vending corner; the fifth floor has a lobby with vending machines, an unstaffed coffee stand, the nursing room and the quiet rooms; the first floor has a multipurpose room that groups and events sometimes take over. The seventh-floor restaurant (CAFETERIA BLUE) is self-service, with a kids' plate at 1,000 yen and a soft omelet over rice (omurice) at 1,400 yen, allergen labeling on every dish to Japan's 28-item national standard, vegan and vegetarian marks, and a bottomless drink bar at 500 yen per person.source2026-08-11

Basics

Fee：The permanent exhibition is ¥630 for adults, ¥210 from elementary school age to 18, and free for children not yet at school. Under-18s go free every Saturday. Adult means 19 and over, a definition the museum spells out in its own campaign notice. A combined ticket with the Dome Theater is ¥940 / ¥310 (¥100 on Saturdays) / ¥100; adding the Dome Theater to a ticket you already hold is ¥310 / ¥100 / ¥100. An annual pass for the permanent exhibition is ¥1,250 for adults and ¥410 for under-18s, sold at the window only. Groups of eight or more pay ¥500 and ¥160. Holders of a Japanese disability, rehabilitation, mental-health, atomic-bomb survivor, war-wounded or welfare-service certificate go free with one companion, and that covers the permanent exhibition, the Dome Theater and the special exhibition. The permanent exhibition is also free on 9 July, on Children's Day for under-18s, on Respect for the Aged Day for over-65s, and on set days of Science and Technology Week and Education and Culture Week. You can enter the building itself for nothing if you are only going to the restaurant, the rest areas or the free kids' space. The special exhibition running to 27 September 2026 costs ¥2,000 / ¥1,300 / ¥900 from age 3, free for age 2 and under, and includes the permanent exhibitionsource 2 3 4
Hours：Open 10:00 to 17:00, with ticket sales and reception closing at 16:30; the museum calls 16:30 the last admission time. Closed on Tuesdays, except when the Tuesday is a public holiday, and from 28 December to 1 January; during the spring, summer and winter school holidays it may open on Tuesdays instead, and extra closed days are sometimes added for maintenance, so check the official opening calendar for your date. Times can change. The big one: the whole museum shuts from 1 October 2026 to 22 April 2027 for building work and reopens on 23 April 2027. You may leave the permanent exhibition and come back in on the same ticket, though a special exhibition may not allow that. Dome Theater screenings run from 10:20 to 16:20; you can go in from ten minutes before, and once a screening has started you cannot enter. The 7F cafeteria keeps museum hours with last orders at 16:30, and from September 2026 it moves to a temporary space while the 7F lounge is refurbishedsource 2 3 4 5 6
Time to allow：2–3 h — The museum's own FAQ (checked August 2026) says about 2 hours, more if you watch the Dome Theater. Its six suggested courses are marked 120 min (four), 180 min (one) and half a day (the family course)source 2
Booking：The permanent exhibition needs no booking — buy on the day at the outdoor ticket booth (10:00-16:30, cash, VISA/Mastercard/JCB/AMEX/Diners, Suica and other transport IC cards, Rakuten Edy, iD and QUICPay+). The museum still recommends buying online because the booth gets busy. The Dome Theater is different: every seat is reserved, so book ahead; same-day seats are sold only if any are left and you cannot choose your seat. Online sales for the permanent exhibition and the Dome Theater open one week before your date and let you pick your seat; there are no refunds and no date changes once you have paid, and preschool children need a ticket of their own when you book online (zero yen for the permanent exhibition, 100 yen if you add the Dome Theater). Special exhibition tickets are sold on separate sites and at a separate counter on 1F opposite the museum shop. Several popular exhibits and the free kids' space hand out numbered tickets on the day, first come first servedsource 2 3 4 Official booking site ↗
Note: the whole museum is closed from 1 October 2026 to 22 April 2027 for building work, reopening on 23 April 2027. The free play room Oyakko Hiroba is recommended for ages 3 and up, runs in 45-minute sessions with everyone leaving between them, children must be with an adult, and on weekends, holidays and busy days entry is by numbered ticket handed out on the daysource 2

Doors open at 10 a.m. and close at 5 p.m., with tickets sold and entry accepted only until 4:30 p.m. The museum closes on Tuesdays (open when the Tuesday is a public holiday) and from December 28 to January 1, though Tuesdays sometimes open during school breaks and extra maintenance closures can appear, so check the official calendar for your date. The big one is the construction closure from October 1, 2026 through April 22, 2027, with reopening on April 23, 2027. A permanent exhibition ticket lets you leave and come back (special exhibition tickets may not), dome theater screenings run between 10:20 a.m. and 4:20 p.m. with doors opening 10 minutes before each start and no entry once a film has begun, and the seventh-floor restaurant follows museum hours with last orders at 4:30 p.m., moving to a temporary location from September 2026 during the lounge renovation.source2026-08-18
The permanent exhibition is 630 yen for adults, 210 yen for ages 6 through 18 and free for preschoolers, with under-18s free every Saturday and adult defined as 19 and over in the museum's own campaign table. A combined ticket with the dome theater is 940 yen, 310 yen (100 yen on Saturdays) and 100 yen, and adding the theater to a ticket you already hold costs 310, 100 and 100 yen. An annual pass to the permanent exhibition is 1,250 yen for adults and 410 yen for under-18s, sold at the counter only, and groups of eight or more pay 500 and 160 yen. Visitors holding a disability, atomic-bomb survivor, war-wounded or welfare-services certificate enter free with one companion, covering the permanent exhibition, the dome theater and special exhibitions. The permanent exhibition is also free on July 9, the museum's anniversary; on Children's Day for under-18s; on Respect for the Aged Day for those 65 and over; and on certain days of Science and Technology Week and Education and Culture Week. Using only the restaurant, the rest areas or the free play space costs nothing to enter, and the Great Antarctic Exhibition running through September 27, 2026 is 2,000, 1,300 and 900 yen for ages 3 and up, free for 2 and under, and includes the permanent exhibition.source2026-08-18
The permanent exhibition takes no reservation, and same-day tickets are sold at the outdoor booth from 10 a.m. to 4:30 p.m. (cash, VISA, Mastercard, JCB, AMEX, Diners, transit IC cards, Rakuten Edy, iD and QUICPay+), though the museum recommends buying online because that booth can get crowded. The dome theater is the exception, with every seat assigned and a booking required in advance; it sells on the day only if seats remain, and then without a choice of seat. Online sales cover the permanent exhibition and the dome theater, open a week before your visit and do let you pick seats, with no refunds and no date changes after purchase. Booking online means preschoolers need a ticket of their own (0 yen for the permanent exhibition, 100 yen with the theater). Special exhibitions are sold through a separate site and a separate counter opposite the first-floor shop, and the popular permanent exhibits and the play space may still need a first-come timed ticket picked up on the day.source2026-08-18
The first-floor exhibition gallery is running the Great Antarctic Exhibition for the 70th anniversary of Japan's Antarctic research, where you can put a hand on real Antarctic ice, walk into a re-creation of an expedition team working in a blizzard, and see an ice core holding 340,000 years of the planet's record along with a meteorite found in Antarctica. Admission is 2,000 yen for adults, 1,300 yen for ages 6 through 18 and 900 yen for ages 3 and up, free for 2 and under, and the ticket covers the permanent exhibition as well.source2026-08-11
The dome theater is running a special screening of BLUE OCEAN DOME, the all-CG film shown at the Osaka-Kansai Expo, remade for the museum's roughly 15-meter (50-foot) dome from a version built for the Expo's roughly 10-meter (33-foot) LED screen. It runs about 10 minutes with no narration, is recommended for upper elementary age and above, and costs nothing beyond a permanent or special exhibition ticket, though you still have to reserve a seat.source2026-08-11

Tokyo's national museum of emerging science fills its floors with exhibits made for touching. A digital globe of the Earth pulls in cloud images from weather satellites each day. The museum says plainly there is no set route. Tickets start at the exhibition gates; outside them are the restaurant, rest areas and a free play room of slopes and ball runs. The play room is for ages three and up, with numbered tickets on busy days. Ear muffs and sunglasses are lent at the information desk to anyone who asks.

Stroller friendly	Yes	You can push a stroller through the museum, and it lends them too — ask a member of staff at the 1F entrance. (The museum never writes 'strollers are fine everywhere' in so many words; what it does is lend them and name exactly one room you cannot take them into.) Every floor from 1 to 7 is served by two elevators, and the museum's own Chinese page describes all its elevators as accessible. The one place strollers cannot go is the Dome Theater on 6F: strollers and large bags are not allowed inside, so leave them at the stroller parking or in a locker before the screening. Staff may also refuse tricycles and similar wheels for the safety of other visitors. Coin lockers are by the entrance to the Symbol Zone on 1F and cost a ¥100 coin that comes back afterwards; anything too big for a locker can be left at the 3F information desk, with no reservations and limited space	Web-checked	checked Aug ’26	miraikan.jst.go.jp miraikan.jst.go.jp miraikan.jst.go.jp miraikan.jst.go.jp
Diaper changing table	Yes	Changing tables are inside the multipurpose toilets on every floor — the museum's Chinese page counts eleven places in the building. The nursing room on 5F has more than a table: each of its two lockable rooms holds a changing bed for lying down, a changing table for standing up and a bin for used diapers. Adult-size changing tables are on 1F and 7F	Web-checked	checked Aug ’26	miraikan.jst.go.jp miraikan.jst.go.jp miraikan.jst.go.jp
Nursing space	Yes	The nursing room is on 5F and men may use it — the museum says so in as many words. It has two lockable private rooms and a shared space. Each private room has a nursing chair, a changing bed for lying down, a changing table for standing up and a diaper bin. The shared space has a nursing sofa, a water dispenser for making up formula and a sink for washing hands. The museum's own family route puts this room on the list of stops, alongside the exhibits	Web-checked	checked Aug ’26	miraikan.jst.go.jp miraikan.jst.go.jp miraikan.jst.go.jp
Indoor / outdoor	Indoor	Indoors — a seven-story building. The official floor map puts every exhibition zone, both theaters, the toilets and the nursing room inside, on floors 1 to 7. The only open-air part still on the museum's eating-area list is the 7F courtyard; the terrace beside the observation lounge dropped off that list when the seventh floor went in for refurbishment (checked 2026-09-22). Food trucks park outside on most weekends and holidays. Getting from the station to the door is outdoors, four to fifteen minutes on foot depending on which station you use	Web-checked	checked Sep ’26	miraikan.jst.go.jp miraikan.jst.go.jp miraikan.jst.go.jp
Family restroom	Yes	Wheelchair-accessible toilets sit outside the exhibition rooms on B1 (parking lot), 1F, 3F, 5F, 6F and 7F, with 80 cm doorways that you open by hand; the museum's Chinese page counts eleven multipurpose toilets in the building. Cubicles fitted for ostomates are on 1F (one in the ladies' and one in the unisex toilet, 90 cm doorways), and on 3F and 5F (90-95 cm). Whether the cubicles have a baby seat to strap a child into is not stated on the official pages	Web-checked	checked Aug ’26	miraikan.jst.go.jp miraikan.jst.go.jp miraikan.jst.go.jp
Diaper disposal bin	Yes	Each of the two lockable rooms in the 5F nursing room has its own bin for used diapers. Whether the multipurpose toilets around the building have one is not stated on the official pages	Web-checked	checked Aug ’26	miraikan.jst.go.jp
English support	English menu & signs	Exhibition labels are written in both Japanese and English, with a few exceptions the museum notes itself, and the videos inside the permanent exhibition carry English subtitles. The floor guide comes in Japanese, English, Chinese and Korean, and the website runs in the same four languages. The Dome Theater lends a free English audio guide — ask as you go in, numbers are limited, and it is a straight English track rather than descriptive audio. Scripts in English exist for two of the Geo-Cosmos shows — Into the Diverse World and Digging the Future — kept by the handrail in front of Geo-Cosmos on 3F and lent at the 3F information desk while copies last. Whether staff speak English is not stated	Web-checked	checked Aug ’26	miraikan.jst.go.jp miraikan.jst.go.jp miraikan.jst.go.jp miraikan.jst.go.jp
Outside food allowed	Designated areas only	You may bring your own food and drink, but only to the places the museum lists as eating areas; nothing may be eaten in the exhibition areas or inside any theater. The list, as the museum published it on 2026-09-22: 1F multipurpose room (sometimes taken by groups or events), 1F Symbol Zone (in the marked spots only), 5F lobby (vending machines, an unstaffed cafe stand, nursing room on the same floor), 7F courtyard, 7F Dome Theater lobby, and the 7F conference rooms. Drinks only, no meals: 1F communication lobby and the 7F drinks corner, both with vending machines. The 7F observation lounge and its terrace have dropped off this list while that floor is refurbished. Food trucks park outside on most weekends and holidays. Inside the Dome Theater nothing at all may be eaten, sweets and chewing gum included	Web-checked	checked Sep ’26	miraikan.jst.go.jp miraikan.jst.go.jp miraikan.jst.go.jp
Kids' toilet seat & step stool	Yes	A family media report says the third floor has toilets designed for children, decorated with astronauts and rockets, so a child can use them alone. The official accessibility page lists toilet fittings in detail — ostomate cubicles, adult-size changing tables, urinals with handrails — but says nothing about a child seat or a step stool (checked 11 Aug 2026).

Elevator	Yes	Two elevators run between 1F and 7F, and one more goes down to the underground parking garage. The ones inside the building measure 180 x 190 cm with a 100 cm-wide, 240 cm-high doorway — wide enough for a side-by-side stroller; the parking-lot elevator is 140 x 135 cm with an 80 cm doorway. They are center-opening, with a voice announcement, braille and handrails on both sides. The museum's Chinese page describes all of its elevators as accessible	Web-checked	checked Aug ’26	miraikan.jst.go.jp miraikan.jst.go.jp miraikan.jst.go.jp
Stroller rental	Yes	Strollers are lent at the 1F entrance — just ask a member of staff, and the FAQ says the same. Do not count on a particular number: the Japanese page says only that numbers are limited, while the English page says thirteen and the Chinese page says four, so treat it as first come, first served. Wheelchairs and power wheelchairs are lent too, and unlike strollers those can be booked: phone any time from a week before your visit up to 17:00 the day before (the day before that if the museum is closed), though numbers are limited and a booking is not guaranteed. Whether either loan costs anything is not stated on the official pages	Web-checked	checked Aug ’26	miraikan.jst.go.jp miraikan.jst.go.jp miraikan.jst.go.jp miraikan.jst.go.jp
Child switch (rider swap)	Not checked yet	Nothing here works like a ride with a height or age limit, so there is nothing to take turns for. Rider swap: not stated
Steps & slope caution	Barrier-free	Built to be rolled through. Two elevators run the whole way from 1F to 7F and a third reaches the underground parking garage; wheelchairs, power wheelchairs and strollers are all lent; wheelchair-accessible toilets sit on six levels (parking lot, 1F, 3F, 5F, 6F and 7F, outside the exhibition rooms); four spaces in the parking lot are reserved for wheelchair users; guide, assistance and hearing dogs are welcome; and the museum publishes photo-by-photo wheelchair routes from each of the three nearest stations. The one exception is the Dome Theater on 6F: the seating is tiered, so the museum warns there may be steps as you move to your seat, and strollers cannot come in with you — two wheelchair spaces per screening are provided instead	Web-checked	checked Aug ’26	miraikan.jst.go.jp miraikan.jst.go.jp miraikan.jst.go.jp miraikan.jst.go.jp
Nursing rooms	Yes	One nursing room, on 5F, holding two lockable private rooms and a shared space. Men may use it	Web-checked	checked Aug ’26	miraikan.jst.go.jp
Diaper changing tables	Yes	In the multipurpose toilets on every floor, plus a changing bed and a changing table in each of the two rooms of the 5F nursing room. Adult-size tables are on 1F and 7F	Web-checked	checked Aug ’26	miraikan.jst.go.jp

Microwave	Not checked yet	Not stated on the official site as of 11 August 2026 — the nursing room's fittings are listed item by item and a microwave is not among them
Room privacy	Yes	Two lockable private rooms inside the 5F nursing room, with a shared space alongside for anyone who does not need a door	Web-checked	checked Aug ’26	miraikan.jst.go.jp
Official family-friendly certificationExtra info — guide only	Not checked yet	No local-government or third-party family certification is mentioned anywhere on the official site as of 11 August 2026
Crowding (guide)Extra info — guide only	Yes	The museum does not publish a crowding chart; it publishes numbered tickets, which tells you the same thing. The free kids' space runs in 45-minute sittings and hands out numbered tickets on weekends, public holidays and busy days, with the times it starts handing them out printed on the official page — 10:00 for the 11:15 and 12:15 sittings, 12:30 for the 13:15 and 14:15 ones, 14:30 for the 15:15 and 16:15 ones. Only the first sitting at 10:15 needs no ticket; you just turn up. Three of the popular permanent exhibits also need a numbered ticket collected on the day. The Dome Theater is all reserved seating and can sell out. Of the outdoor ticket booth the museum says it can get busy and recommends buying online instead	Web-checked	checked Aug ’26	miraikan.jst.go.jp miraikan.jst.go.jp miraikan.jst.go.jp
Lost-child supportExtra info — guide only	Not checked yet	Not stated on the official site as of 11 August 2026. There is a first-aid room on 1F with a nurse on duty, but nothing about where to report a lost child or whether the museum pages people
Stroller access notesExtra info — guide only	Yes	Two things to settle before you start pushing. First the stroller: it goes everywhere in the building except the Dome Theater on 6F, so if a screening is on your list, decide now whether to use the stroller park outside the theater, a locker, or a carrier. Second the luggage that rides under the stroller: coin lockers are on 1F, on the left in front of the entrance to the Symbol Zone, and take one ¥100 coin per space that comes back afterwards, in three sizes (large 33 x 42 x 81 cm, 24 of them; medium 33 x 42 x 53 cm, 24; small 33 x 42 x 39 cm, 80). Anything that does not fit goes to the 3F information desk, which takes no reservations and can turn you away when its space is full. Tricycles and similar wheels may be refused at the door for the safety of other visitors	Web-checked	checked Aug ’26	miraikan.jst.go.jp miraikan.jst.go.jp miraikan.jst.go.jp
Quietness (guide)Extra info — guide only	Not checked yet	The museum does not rate itself as quiet or noisy. Instead it publishes a sensory map that marks, floor by floor, where the sound is very loud, loud or quiet, alongside bright and dark places, crowds and benches — so the answer here depends on which room you are standing in
