Tatsukushi Marine Park

Tatsukushi Underwater Park was the first marine park in Japan to be designated as a national park in China, and is a great spot for recreational diving that even beginners can enjoy. Diving is permitted except during typhoons and summer storms, so there is essentially no off-season. There is a colony of coral reefs underwater, which is said to be the largest in Japan. You can observe the beautiful underwater scenery from a glass-bottom boat.
