What makes it 78% Solo-Friendly: A solo traveler can explore 50 tanks, outdoor mammal park, and shows at own pace without coordination. Frequent buses and a 3-hour suggested stay make it an easy independent outing.
Why 3-4 hours visit duration is ideal for solo trip: This allows time to see main exhibits, catch multiple shows, and feed seals at a relaxed pace.
Main Aquarium Exhibits:
Walk through indoor tanks housing over 250 cold‐ and temperate‐sea species.
Tip: Begin at the Okhotsk Sea tank in the morning to photograph the rare harbor porpoises before crowds arrive.
Dolphin & Sea Lion Shows:
Watch high jumps and playful tricks in the outdoor stadium.
Tip: Arrive 10 minutes early for front‐row seats and hear trainers’ English commentary clearly.
Penguin Time:
See Humboldt penguins march from pool to sea in a choreographed hike.
Tip: Check the schedule at the entrance and stand on the west platform for unobstructed views.
Seal Feeding Experience:
Buy a fish bucket and feed seals up close at the marine mammal park.
Tip: Purchase the 500 ¥ bucket at the kiosk just before the outdoor pool and hold fish at seal mouth level for best photos.

An interesting aquarium with lots of sea creatures to look at. Penguins and seals were a delight. I kind of feel that the dolphins' pool was too small for these magnificent mammals. Like whales, sharks and sea turtles, they belong in the ocean. There's a good restaurant, but it was loud and crowded. I think it was a holiday or there were simply too many tourists about.

We regret we just found out this amazing aquarium this summer! I agree with the previous reviews about not too much but everything is excellent! 1. Check their website for activities timetable. 2.

If you didn’t get to see all the things s...

Rephrased and Corrected Text This is an old aquarium with a marine mammal area that features shows. While the aquarium itself isn't very big, I was amazed by the size of the animals; they're huge! The marine mammal area has shows with walruses, seals, penguins, and sea lions. Some of the animals seemed too lazy to perform, but the trainers didn't force them, which I thought was a nice touch. They ...

the exhibition is not very big but educational with a good collection of rare species. The shows are entertaining especially the penguins going to picnic. It is a perfect sized aquarium ; you get enough but not exhausted. There are not computer simulations nor games to attract children, only real natural things. So don’t need to worry about screens. 👏

Although it was a little crowded, it was still such a fun experience! You even get to buy fish to feed the sea lion – definitely a highlight. Not to forget the penguin walk, which was super cute to watch! Just a heads-up: people start gathering really early, so it’s hard to get a good spot unless you’re there ahead of time haha. Overall, a fun and memorable visit – great for families and animal ...
Penguin Time runs April–October; winter months have fewer outdoor events but quieter indoor exhibits. Check show times ahead.
