Shuzenji Onsen
The oldest hot spring town on Izu, built along a river with a bamboo path and a spring in the middle of the water.
Updated 20 October 2026
Shuzenji takes its name from the temple founded here by tradition in 807 by Kobo Daishi, who is said to have struck the rock in the river bed with his staff and brought up hot water. That spring, Tokko no Yu, is still in the middle of the Katsura river, marked by a small roofed structure on a rock; it can no longer be bathed in but the water runs. The town is small, built along both banks with red bridges, and the two set pieces are the bamboo path - a short walk under a planted grove with a round bamboo bench in the middle - and Chikurin no Komichi, its lit continuation. The temple has a museum with a mask connected to a grim episode in the Kamakura shogunate's family history. Several inns date back centuries, and the writer Natsume Soseki nearly died of a haemorrhage at one of them in 1910.
History
The hot springs have been used for more than fourteen centuries, and folklore says Kobo Daishi, who lived from 774 to 835, found them by probing the rocks of the river with his staff (Wikipedia, Shuzenji Onsen).
