Iwakuni’s eco bath that makes use of waste heat from waste incineration, with a humid 84°C sauna and a refreshing cold plunge bath
Yamaguchi Iwakuni City
Spa Sunrise stands inside Hinode Park in Iwakuni City, Yamaguchi Prefecture, next to the Sunrise Clean Center. As an eco-friendly public bath facility that makes use of waste heat from the neighboring waste incineration plant, it has long been loved by local residents, tourists, and personnel from the U.S. Marine Corps Air Station Iwakuni alike. About a 7-minute drive from the east exit of Iwakuni Station, it is in a convenient location for dropping by between sightseeing in Iwakuni and visits to Kintaikyo Bridge.
