Traveler highlights

Keya no Oto is a sea cave on the Itoshima coast, formed as waves eroded basalt. Designated a national natural monument in 1966, it is Japan’s largest basalt cave, measuring 64 meters high, 90 meters deep, and 10 meters across at the opening. Hexagonal and octagonal basalt columns line the surrounding cliffs. Since access by land is difficult, sightseeing boats from Keya Fishing Port offer a close view of the cave mouth and rock face; in suitable sea conditions, boats may enter. Seen from the water, the cave’s scale and basalt patterns stand out against the Genkai Quasi-National Park coast.
