Takayama Onsen Dome is located in Nakatane, on Tanegashima Island, Kagoshima Prefecture. The sulfurous, slightly acidic water (pH 6.5) reaches around 44 °C (111 °F). An indoor bath, a rotenburo-style outdoor bath and a sauna round out the offering.
Insider tip — Takayama Onsen Dome on Tanegashima Island draws intensely sulfurous geothermal water from the same volcanic system that makes the island's southern tip one of Kagoshima's most geothermally active zones. The covered dome facility provides year-round bathing regardless of the subtropical typhoon season. Tanegashima's dual identity — home to Japan's primary space rocket launch facility and a centuries-old onsen culture — creates a uniquely modern-ancient atmosphere. The sulfurous water is appreciated for its soothing effect on the skin.
