The Shimonoseki Marine Science Museum, affectionately known as “Kaikyokan,” is an aquarium in the Karato district of Shimonoseki City which opened in 2001. The Museum is famous for its collection of over 100 species of Fugu (Pufferfish) from all over the world and for its exhibit of a complete skeleton of a Blue Whale.

Review of Kaikyokan

TripAdvisor Traveler Rating
Reviewed:2018/03/04 Very interesting puffer fish exhibit.
Shimonoseki is famous for puffer fish. But I cant remember seeing so many species of puffer fish in an aquarium. In general, an enjoyable visit.
Reviewed:2018/02/14 If you the Puffer fish fan, this is a good place to visit
The aquarium itself is not so big as the Osaka one but it has a collection of more than 100 types of puffer fish (Fuku:in Japanese). There is also a small area for sea show but you its only one...

          Heading west along Japan's largest island, Honshu, the very last prefecture you'll reach is Yamaguchi, separated from Kyushu by a small strip of water known as the Kanmon Straits, which the far-reaching harbor city Shimonoseki looks over. With water at every turn, the seafood of Yamaguchi is an indisputable highlight, and we're not talking just the usual fish dishes - the notorious fugu, or puffer fish, is a Japanese delicacy that was discovered in Yamaguchi prefecture, making it the best place to try it out.
