Nanatsugama

Nanatsugama, located along the rugged coastline of Yagataishi in Karatsu City, Saga Prefecture, is a stunning natural attraction shaped by the relentless forces of the Genkai Sea. Over countless years, powerful waves have carved into the black basalt cliffs, creating seven distinct sea caves whose striking formation quietly showcases the enduring power of nature.

The cliffs here are notable for their regular columnar joints in the dark rock, creating a dramatic contrast against the vivid blue ocean. Visitors can take a sightseeing boat to get up close to the largest cave, experiencing the unique thrill of watching waves surge into the cavernous depths—an encounter that can only be appreciated from the water.

For those who prefer to stay on land, a walking trail runs along the top of the cliffs, inviting exploration all the way to the tip of the cape. From the lookout point, you can enjoy panoramic views of the white-capped waves below and the impressive line of sea caves. Surrounded by lush greenery and the sound of crashing waves, a walk here presents a peaceful yet powerful connection to the coastal landscape. Nanatsugama is truly a place where visitors can feel the dynamic beauty and timeless energy of the sea.
