Cruising in Dogashima, Nishi-Izu, Shizuoka Prefecture: Visit Tensodo Cave and Sanshiro Island by Sightseeing Boat

Dogashima Marin in Nishi-Izu Town, Kamo District, Shizuoka Prefecture, where you can enjoy Suruga Bay by sightseeing boats. As well as famous locations such as Sanshiro Island, known for Tensodo Cave and its tombolo phenomenon, the boats also tour the beautiful coast made up of layers formed from 20 million to 2 million years ago, visiting sunset spots such as Koganezaki Park and Otago Coast.
Tensodo Cave, a National Natural Monument, is a particular must-see. Light shines down through a hole in the roof of the cave, causing the water below to glow a mystical blue. This approximately 130-meter long sea cave created by erosion from the wind and waves is a place of symbolic beauty in Dogashima.

Sanshiro Island lies in the waters off the coast. The “Sanshi” in its name means “three or four.” It gets its name from the fact that it can look like three or four islands based on the angle from which you view it. In low tides during spring tides, a 200-meter long sandbar path appears, connecting the island to the shore and allowing visitors to cross over without even getting their feet wet. This is known as the tombolo phenomenon.

Koganezaki Park has a promenade. Here, you can feast your eyes on the breathtaking sight of Mount Fuji across the sea and the surface of the rocks glowing amber as the sun sets into the sea. The rocks protruding out of the sea look like the sideways view of the face of a horse, earning them a place on a list of "Japan’s top 100 strangely-shaped rocks".

The Otago Coast is a romantic sunset spot. The sight of the sun setting between the Tagojima’s two islands of Ojima and Mejima during the vernal and autumnal equinoxes is particularly mystical.
