MoreWhat kind of place
Tokyo Sea Life Park is an aquarium inside Kasai Rinkai Park in Edogawa Ward, about 20 minutes by train from Tokyo Station.
The entrance is a glass dome, and inside are more than 500 species, from oceans around the world to the rivers and shorelines closer to home.
At its center is a doughnut-shaped tank holding 2,200 cubic meters of water, where bluefin tuna circle in a school.
In April 2026, this aquarium and the three other zoos and aquariums run by the Tokyo metropolitan government were added to Japan's official museum register.

With kidsThe part that matters
Saturdays, Sundays, and holidays are the busy days here, so check the crowd forecast the aquarium posts for each day and you can pick a quieter one.
Children stop at the penguin exhibit, one of the largest in Japan, where the world's smallest penguins waddle and swim.
You can bring your own lunch into the restaurant if you tell a staff member, who will also warm baby food or pour hot water for formula.
There are no strollers to rent, so bring your own and take it inside with you rather than leaving it at the ticket office.
One family with a five-year-old and a two-year-old got through it in just under two and a half hours, lunch at the restaurant included.

By age0-1 / 2-3 / 4-6
- Ages 0-1Strollers are allowed inside, so your baby can stay in the seat as you go round. In the doughnut-shaped main tank holding 2,200 cubic meters of water, bluefin tuna swim past in a school. At the penguin exhibit, one of the largest in Japan, the penguins swim right by.There are two nursing rooms: the rest house beside the main gate and the 2nd floor of the main building. Only women may enter the rest house nursing room; the 2nd floor has three mamaro baby care booths, and men should ask staff about using the main building room. For formula, ask staff at the information counter, the restaurant, or the ticket office for hot water, and ask restaurant staff if you need baby food warmed in a microwave. Diaper changing tables are in every restroom in the park. No strollers are lent, so bring your own, and since the only stroller parking is at the ticket office, plan to push it through the exhibits.
- Ages 2-3There are galleries of familiar waterside life, among them Tide Pool, Creatures of the Shore, and Life in Freshwater. You can watch feeding time for the tuna, the penguins, and the seabirds. Admission is free through 6th grade.The hands-on touch program is suspended for now with no restart date, and visitors do not feed the animals. If touching was the draw, time your visit around feeding time or a spot guide instead. Child toilet seats are fitted on every Western-style toilet in the main building. Sensory goods such as ear muffs are lent free, first come first served, at the information counter on the 2nd floor of the main building, and a calm down space for a rest sits beside the escalator there.
- Ages 4-6More than 500 species from seas around the world and from waters close to home. At feeding time a guide explains while the animals eat, so a child can watch and listen at once. The galleries are named by place, such as Deep Sea, Bioluminescence, Arctic and Antarctic Seas, and Coral Reef, so a child can pick which sea to visit next.Admission is free through 6th grade; adults pay 700 yen. Three spots need stairs: the tank display below the stairs in Penguin Ecology, the passage above the stairs in The Sea of Tokyo, and Bioluminescence. A Sunday visit with a 5- and a 2-year-old (2025) took just under two and a half hours including lunch at the park restaurant. Packed lunches can be eaten in the restaurant if you tell a staff member, and on a rainy day the roofed places to eat are part of the restaurant and the rest house by the main gate.

A glass dome marks the entrance, inside Kasai Rinkai Park. A doughnut-shaped tank of 2,200 cubic meters holds a school of bluefin tuna, and the penguin display is among the largest in Japan. Coral reef, deep sea, polar waters and tide pools carry more than 500 species. At feeding time, keepers explain what the tuna, penguins and seabirds are eating. The main building keeps a calm-down space, lends ear defenders free, and runs quiet hours six times a year.
| Stroller friendly | Yes | You can go in with a stroller, but there is no stroller parking inside the building — the only parking spot is at the ticket office. Three displays can only be reached by stairs: the tanks below the steps in the Penguin area, the passage above the steps in the Sea of Tokyo area, and Bioluminescence (the same three places a wheelchair cannot reach).

| Nursing space | Yes (2) | Two: the rest house beside the main gate, and the second floor of the main building, where three 'mamaro' baby-care pods stand.

| Outside food allowed | Yes | You may bring a bento and eat it in the restaurant — tell a member of staff, since other people are eating what they ordered, and groups are asked not to. Under a roof in the rain, the choices are part of the restaurant and the rest house by the main gate; there is no covered space big enough for a large group.

| Stroller access notesExtra info — guide only | Yes | Three things worth settling before the gate. The stroller: it can come in, but the only parking spot is at the ticket office, and three displays need stairs. Luggage: there is no left-luggage counter, only coin lockers — inside the rest house by the main gate (small 200 yen, up to extra-large 500 yen) and beside the information room on the second floor of the main building (small only), usable until 17:00. Getting there: the park has no parking lot of its own, so use the Kasai Rinkai Park parking lot, or come by train — Kasai Rinkai Koen station on the JR Keiyo line is a five-minute walk, about 20 minutes from Tokyo station. Re-entry is possible: ask staff at the gate or the information counter. | Web-checked | checked Aug ’26 | tokyo-zoo.nettokyo-zoo.nettokyo-zoo.net |
