Sueyoshi Onsen Miharashi no Yu (Hachijojima-island)
Hachijojima in the Izu Islands has the best open-air bath in Tokyo. “Sueyoshi Onsen Miharashi no Yu” is a town-run day trip hot spring located in the Sueyoshi district in the eastern part of the island. The greenish hot water is a rich chloride spring. If you have a panoramic view of the sea, you can experience the best feeling of liberation with nothing to block.
