Dogashima

Higashi-Izu / Minami-Izu / Nishi-IzuArea

"Dogashima is a famous scenic spot in Nishiizu Town, Kamo County. There are a number of tourist attractions in the area, including the Sanshiro Islands - comprising Zo-jima, Nakano-shima, and Taka-shima-and the Tensodo sea-cave, which has been designated a National Natural Monument. Sightseeing cruise boats operate throughout the year; visitors can look up at the sky through the opening in the roof of the Tensodo sea-cave (also known as the ""Blue Cave""), which was created by sea erosion of tuff (a type of rock formed from volcanic ash), and can also view the tombolo phenomenon, a narrow strip of land that links Zo-jima (traditionally known as Denbei-jima, this is the closest of the Sanshiro Islands to the Izu Peninsula) to the mainland at low tide. This area is also famous as the setting for the tragic love legend of Izu no Sanshiro and Koyuki."
