What Travellers Say
Reviews Summary
Visitors praise Kaikyokan Aquarium for its engaging exhibits, particularly the diverse pufferfish collection and impressive dolphin shows. It's a great spot to escape the heat and enjoy a full day, with the flexibility to revisit exhibits after a meal at the nearby Karato Fish Market. Some find parking expensive, and while translations are available, live interpreter services are limited.
"If you want to beat the heat and have fun while doing it, this is the perfect place, especially if you have kids! Our family spent the entire day here and around the wharf where the aquarium is located. An aquarium ticket lasts a whole day with the QR code. We were able to go in early in the morning, get some exhibits looked at, pop out for a fresh sushi lunch at the nearby Karato Fish Market, and then pop back into the aquarium to look some more or revisit previous exhibits.
The dolphin shows were amazing, but definitely get there 30 min early for seats, and not every show is the same since they change the animals sometimes.
Our favorite spot to rest was the sofa area in the corner of the Subantarctic Penguins on B1F. If you get there around 1:00 PM, you'll see angelic light streaming down the tank water which was stunningly beautiful when the penguins would swim and dive with a trail of bubbles behind!
There are English translations for almost everything displayed, but no interpreters for whatever the caretakers are saying, but translating apps come in real handy for those times!
Definitely recommend going more than once!"

"It's another aquarium in Fukuoka, slightly small, but each has its strength and weaknesses against other aquarium. If like to see puffer fish I think this place had the most variety in Japan....😲 🐟 Great for fish lover. Not forgetting the std seal n dolphins act..👍"
Dan Chong
"Small aquarium.
A place I went to to escape the heat in very hot weather. Just a small aquarium.
There are dolphin and seal shows a few times a day, and there is also a fish feeding show.
I couldn't find a parking lot, so I parked in the parking lot across the street toward Karato Market and paid 800 yen. Parking fee is too expensive.
There is a restaurant on the beach on the first floor where you can eat while looking at the aquarium. If you don't want to go into the aquarium, you can eat ice cream (500 yen) at this restaurant while looking at the aquarium."
