What other travelers are saying about Tokyo Sea Life Park
just visited Tokyo Sea Life Park, tucked away in the scenic coastal setting of Kasai Rinkai Park in Tokyo. It’s very convenient to reach: from Tokyo Station take the JR Keiyō Line to Kasai-Rinkai-Koen Station, and from there it is only a 5-minute walk to the aquarium entrance. 
Once inside you’ll be immersed in an incredible marine world: one of the signature exhibits is the vast donut-shaped tank holding hundreds of bluefin tuna, a truly memorable sight. 
The facility also features one of Japan’s larger penguin habitats and a plethora of species from tropical seas, temperate zones, even arctic waters — over 600 different sea-creatures and many unique habitats. 
For getting there, if you’re coming by car note that the aquarium has no dedicated parking lot, so it’s highly recommended to use the train, especially on holidays and weekends. 
After your aquarium visit, you can stroll around the surrounding Kasai Rinkai Park — enjoy fresh sea breeze, views of Tokyo Bay and the large Ferris wheel in the park. 
Practical tip: allow at least 1–2 hours for the aquarium portion; if you plan to also ride the Ferris wheel or explore the park grounds, budget half a day. 
Overall, Tokyo Sea Life Park offers a relaxed alternative to busier Tokyo aquariums — ideal for a calm, memorable outing with nature, sea-life and waterfront scenery.”
Getting to the park is easy with various public transport options. By train, Kasai Rinkai Koen Station on the JR Keiyo Line is just a 5-minute walk away. Buses from Tokyo Disney Resort, Urayasu, or Funabori also stop at "Kasai Rinkai Koen" near the park. If driving, it's accessible via the Shuto Expressway Wangan Line, with nearby paid parking available.
In addition to its marine exhibits, the park offers educational programs, a gift shop, and a restaurant. It does not have a parking lot but is near toll parking areas. Public transport is recommended during holidays and weekends.
Yes, groups of 20 or more paying individuals are eligible for a 20% discount, provided they enter the park together one entry at a time. This option is excellent for school trips, company outings, or significant family visits.

Amazing marine life experience!
Tokyo Sea Life Park is a fantastic place to explore the ocean world up close. The aquariums are well-designed, clean, and showcase a wide variety of marine creatures, from colorful tropical fish to majestic penguins and seals. The park is family-friendly, educational, and perfect for a relaxing day out. Great for kids, couples, or anyone who loves marine life and photography!
It’s a decent aquarium for what you pay for which was 700 yen. It was cool to see all the different fish they have from around the world. The tuna were really cool to see but they are in a really small enclosure for how many tuna there are. Penguins where cute and seem to be chill. Decent place to kill some time after walking around the park.
My husband and I took our 10 month old son to this spot last month. It was a week day so it was not crowded at all. He was able to look at all the sea creatures at his own pace. We also went on the ferris wheel and it was so fun. My husband and I definitely had a great time reading all the information beside the fishtanks.
Visited during Tokyo Citizens Day which was a mistake since I had to skip a few exhibits, but the variety and displays I did see were lovely!
It's a nice place that is absolutely worth the price of the regular ticket because it has cool areas such as a touch tank that even expensive aquariums in Tokyo don't offer.
I'll definitely visit again on a quieter day.
