The island is connected to the mainland, and you can walk across at low tide
Shizuoka Prefectural Tourism AssociationTombolo is a phenomenon where a strip of land shows up between an island and the mainland at low tide. Dogashima Coast is a sightseeing spot where visitors can experience this rare phenomenon. At low tide, a pathway toward the Sanshiro Islands, consisting of Denbei Island, Nakano Island, Okinose Island and Taka Island 200 m offshore, will appear and people can walk on it.
A cave called Tensoudou, designated as a natural monument, is also a must-see spot. This is a place where waves have cut a hole in part of a stone wall. The inside of the cave can be observed from a sightseeing boat. A large opening is at the ceiling of the center of the cave, and you can see the blue sky through it. The blue sea surface shining with the sunlight seeping through the hole is a mystical view. You can also look down through the hole above the cave if you take a footpath.
