Taiyo no Sato Onsen Center, also called Tosenbo, is in Nagashima, Kagoshima Prefecture. The sodium-chloride thermal water flows at 39°C, with an indoor bath, an outdoor rotenburo bath and a sauna.
Insider tip — 'Tosenbo' at Taiyo no Sato Onsen Center (太陽の里 — village of the sun) on Nagashima island, northern Kagoshima — connected to Kumamoto by the Nagashima Bridges crossing the fast-flowing Hayasaki Straits. Nagashima's subtropical climate supports Japan's finest mandarin orange (mikan) orchards and yellowtail (buri) fisheries. The Kuroshio Current warming these waters also feeds the island's geothermal system.
