Sakura Onsen, part of Sakura Park Golf in Utsunomiya, Tochigi Prefecture, offers sodium-chloride water at 41°C. The site includes an indoor bath, an outdoor rotenburo pool and a sauna.
Insider tip — Sakura Onsen at the golf park serves the western Utsunomiya hills where cherry-lined drives and thermal bathing combine in the pastoral zone between the Nasu volcanic highlands and the Kanto plain edge. The Utsunomiya area has been a cultural crossroads since antiquity — the city is equidistant between Nikko, the Nasu imperial resort, and the Kinugawa gorge spa district, making it the logistical heart of Tochigi thermal tourism.
