Nanatsukama

Nanatsugama is a sea cave located on a cape that juts out into the sea, named after the seven holes that open up into it. The magma that flowed out of the volcano rapidly cooled in the seawater, forming rare rock formations called columnar joints. These were then eroded by the rough waves of the Genkai Sea, creating the seven caves. You can tour the caves on the sightseeing boat, Ika-maru. You can also see them from underwater through activities such as snorkeling and diving, making it a natural cave system where you can enjoy the mysterious scenery!
