The town of Keya is awesome in many ways. It’s got sandy beaches, some of the best surf points, fresh seafood restaurants, a golf course, and it’s home to many talented craftspeople. It’s also the location of one Kyushu’s wondrous power spots: the sea caves of Keya no Oto. It’s a huge cave with columned walls of pitch-black hexagonal and octagonal rocks. Measuring 64 meters high and 90 meters deep, it faces the rough waves of the Genkai Sea and it’s one of Japan’s three largest basalt (volcanic rock) caves. Between mid-March and November you can get up close on a 25-minute boat tour and if the water is calm, the boat will enter the cave.
