Ganmon 巌門

Sea cave along the rugged coastline with boat rides

Ganmon is a sea cave on the Kongo coast of the Noto Peninsula. The cave was formed as water eroded a sizeable hole into a rock rising out of the sea. The rock is 6 meters wide, 15 meters high, and 60 meters deep, with an old pine tree growing on top.

Boat rides from mid-March to mid-November take visitors around Ganmon and other nearby rock formations along the rugged Sea of Japan coast.
