Aquamarine Fukushima
SaveAn aquarium of nine exhibit zones, with a sushi counter facing the big tank.
Outdoors, a shallow beach lets small children wade in through the warmer months and spot starfish at their feet.
MoreWhat kind of place
The aquarium goes by the name Aquamarine Fukushima and is run by the Fukushima Marine Science Museum, a public-interest foundation.
The displays are split into nine zones, among them the evolution of life in the sea, the rivers and coast of Fukushima, a coral reef, tropical Asian waters, and the sea mammals and seabirds of the northern seas.
Children get a building of their own, Aquamarine Egg, with an otter pool, a shallow wading beach and woodland play areas.
The lot out front holds about 1,600 cars, and lot PW1 keeps five priority spaces for pregnant women and for families with children not yet in first grade.

- The lockers are near the entrance gate and in the main building entrance, and can be used from 9:00 a.m. to 5:30 p.m. (to 5:00 p.m. from December 1 to March 20).source
- Bags too big for the lockers can be left at the information desk by the entrance.source
- There is a first-aid room at the main building entrance, and if anyone feels unwell you can tell a nearby staff member.source
- There is a restaurant on the first floor (Aqua Cross) and a sushi restaurant in front of the big tank on the second floor (Shiome no Umi).source
- A rainy day still works here, but bring an umbrella, since much of the path from the entrance gate to the main building is uncovered.source

With kidsThe part that matters
Walking the nine exhibit zones takes an hour and a half to three hours, so plan on a long stop rather than a quick walk-through.
In the warmer months, small children can wade in at a shallow beach outside and spot starfish at their feet.
Strollers are free to borrow at the main gate, but they cannot be reserved and lending sometimes stops when the aquarium is packed, so ask as you go in.
The whole site is step-free and an elevator links all four floors, so you can push a stroller through every zone.
Lunch is a sushi restaurant on the second floor facing the big tank, so the kids keep watching the fish while you eat.

- About 90 minutes round the building, and sushi from ¥825 eaten standing at the 2,050-tonne triangular tunnel tank.source
- A baby and a 3-year-old. Nursing room on 1F, baby beds in the accessible toilets; the evolution hall scared the girl.source
- Rod and bait ¥1,000, then ¥200 a fish to have it fried. Same-day only, 30 minutes max, and every catch must be eaten.source
- With a 2-year-old. No dolphin show; you wade in the outdoor tidal beach. Showers are provided but no towels to borrow.source
By age0-1 / 2-3 / 4-6
- Ages 0-1Inside the children's hands-on building, Aquamarine Egg, there is a room for small children called Gorogoro Hiroba, where they watch a tank, play with stuffed animals and look at books — and that room has its own baby care room with a nursing booth, a diaper-changing table and a handwashing sink. The aquarium is step-free throughout and an elevator links floors 1 to 4, so the nine exhibition zones can be done without taking the baby out of the stroller.There are three baby care rooms. The one in the first-floor entrance hall has two private nursing booths, two diaper-changing tables and a handwashing sink; the one at the outdoor Aquamarine Egg has a nursing booth and a sink; the one inside Gorogoro Hiroba has a nursing booth, a changing table and a sink. Hot water for formula comes from the first-floor entrance if you ask a staff member, and microwaves for warming baby food are at Aquamarine Egg on the first floor and at the fishing area kitchen. Disposable diapers are sold at the shop inside. Strollers are lent free at the main gate by the ticket windows — no reservations, and lending can stop when the aquarium is very crowded; they are the lightweight folding type, usable from around two months. Parking lot PW1 keeps five spaces for families with young children.
- Ages 2-3The children's hands-on building, Aquamarine Egg, breaks into an animal play forest, a woodland walk, a countryside area, an otter pool and a shallow wading beach. The wading beach is outdoors and shallow enough to walk into and look down at your own feet, and it doubles as one of the places where you may eat a packed lunch, so splashing and eating can take turns.You may eat a packed lunch on the first-floor south terrace, in the outdoor plaza or at the wading beach, but none of them has a roof, so they are out in bad weather. Rough weather can also close the outdoor areas themselves — the woodland walk, the wading beach, the countryside area and the animal play area at Aquamarine Egg. A rainy day still works indoors, but bring an umbrella: much of the path from the entrance gate to the main building is uncovered. Restrooms with a changing table are the accessible restroom beside the northern-seas exhibit on the fourth floor, the women's restroom by the keepers' research reports on the second, the accessible and women's restrooms in front of the uminos museum shop on the first, the spot to the left of the Aquamarine Egg entrance, and the accessible outdoor restroom.
- Ages 4-6The exhibits are laid out as nine zones — the evolution of life in the sea, the rivers and coast of Fukushima, sea mammals and seabirds of the northern seas, the Oceanic Galleria, tropical Asian waters, the coral reef sea, the Oyashio ice box, the meeting of the currents, and the sea of Fukushima and the road to the continental shelf — so a child can pick which one to head for next. In front of the big tank on the second floor is a sushi counter, Shiome no Umi, where the seat you eat at faces the fish swimming past.Walking the exhibits takes about an hour and a half to three hours, and about two hours to half a day if you join a hands-on activity such as the fishing. Admission is free for preschool children and 900 yen from elementary school age. At the exit there is a re-entry stamp, pressed on the back of your hand and on your ticket, so you can go out to the plaza for lunch and come back. The aquarium is open 9:00-17:30 (to 17:00 from December 1 to March 20), with last entry an hour before closing.

The displays run from Fukushima's rivers and coast to the sea mammals and birds of northern waters. Tropical Asian wetlands, coral reefs and the currents off Fukushima follow. On the second floor a sushi counter sits in front of the big tank. Outside stands a children's building, Aquamarine Egg, with an otter area and its own outdoor zones. Inside it a small room lets toddlers watch a tank while playing with soft toys and books.
