Sakamoto Onsen is located in Kagoshima, on the volcanic southern island of Kyushu. Its thermal sodium-chloride water reaches 42°C, with an indoor bath, outdoor rotenburo and sauna on offer.
Insider tip — Kagoshima's dense network of sentos reflects extraordinary volcanic productivity; Sakamoto Onsen's name resonates with Sakamoto Ryoma — the legendary Satsuma/Tosa samurai visionary who engineered the alliance that brought down the Shogunate and launched the Meiji Restoration. The Satsuma domain (modern Kagoshima) was the military force that transformed Japan; its fighters bathed in the same thermal waters before marching north in 1868 to forge modern Japan. Sakurajima's column of smoke is perpetually visible from the city streets.
