Makurazaki; Nagisa Onsen is located in the town of Makurazaki, Kagoshima Prefecture, on the south coast of Kyushu. Its iron-rich thermal water measures 41°C. The facility offers an indoor bath, an outdoor bath (rotenburo) and a sauna.
Insider tip — Makurazaki Nagisa Onsen sits near the southern tip of Kyushu where the Nagisa coastline meets volcanic terrain, producing richly mineral iron-bearing water. The oceanside setting means sea breezes drift through the outdoor areas, blending salt air with the warm mineral steam. Iron waters here are especially valued in winter for their heat-retaining properties. Combine a soak with a fresh bonito meal at the adjacent harbor market.
