Matsumoto Onsen, attached to the Hiranogaoka Taiikukan sports complex, is located in Kagoshima City, Japan. Its sodium-chloride thermal water reaches around 40°C. An indoor bath, an outdoor rotenburo bath and a sauna round out the facility.
Insider tip — 'Matsumoto Onsen' at Matsumoto Hiranogaoka Taiikukan (sports and community center) in the western Kagoshima coastal area. 'Hiranogaoka' (平野ヶ丘 — flat field hill) offers views toward the Koshikijima Islands off the western Satsuma coast — three islands known for ancient stone-age remains and pristine coral reefs. The combination of sports facility and hot spring reflects Japan's holistic approach to community wellness.
