Boat diving in Kumomi

The Izu Peninsula is a rare place in the world where the Philippine Sea Plate is located just above the Eurasian Plate, and its geological value has attracted worldwide attention and has been certified as a UNESCO Geopark. ..

Diving in Kumomi is where you can feel the real thrill of the unusual terrain.

You can swim around the intricately intricate cave endlessly, and enjoy macros such as sea urchins who prefer dark places. Above all, the beauty of the light that shines into the cave in the high transparency is impressive.
