Pretty neat place to drop by! There's a little aquarium at the basement/underwater section where you can actually see the outside. The aquarium itself isn't too large, but has some neat creatures. When I visited (October 2025), they also had sturgeon that you can feed for ¥200.

The main reason that this place gets 5 stars is for the crab claw plush lottery. Otherwise, the underwater aquarium wasn’t that interesting and most of the other features seem to be aimed at children.

The small aquarium inside was charming—few exhibits, but each had detailed, handmade info signs. Loved the personal touch! Great spot to see sea creatures and drift ice in winter

2️⃣0️⃣1️⃣9️⃣0️⃣8️⃣0️⃣1️⃣ Never been inside a underwater tube before until now. We were fairly deep ... at least that was what we have been told. The windows were so dirty so we can't really look out to see the sea bed which was quite disappointing for me. Nonetheless, that did not ruin my whole experience. Get to see up-close (well as close as the glass allows) some pretty cool marine life. Didn't bother remembering what they are call. I was too busy trying to catch its attention so it would look into my camera :) I bet this place will be awesome during winter. Given the opportunity, I would love to come back here during winter. Appreciate if you leave a LIKE if you find my comment useful. Thank you for your support.

Could do with a miss to be honest, great view from the top though which is free to access. Small aquarium in the basement which is paid entry, doesn’t justify the cost. There was a cool octopus there however and considering I have never seen an octopus up close 2 stars
