    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.
  • 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...
  • Real and happy times
