Issa Onsen, attached to the Oshokujidokoro Issa restaurant, is located in Kirishima, Kagoshima Prefecture, Japan — a volcanic area rich in hot springs. Its sodium-chloride thermal water reaches around 40°C, with an indoor bath, an outdoor rotenburo bath and a sauna.

Insider tip — 'Issa Onsen' (一茶 — one tea, or the name of poet Kobayashi Issa) at Oshokujidokoro Issa — a restaurant-onsen in Kokubu, Kirishima city. Kobayashi Issa (1763-1828) was one of Japan's greatest haiku masters, famous for poems of compassion toward small creatures. The combination of meals and thermal bathing (shokuji-onsen) is a beloved format in Kagoshima, where volcanic hot spring culture permeates every aspect of daily life in the shadow of Kirishima's active volcanic chain.
