Shinto Onsen, known as Fureaikan, is located in the village of Shinto-mura, Gunma Prefecture. Its sodium-chloride thermal water is kept around 40°C (pH 7.3), with an indoor bath, an outdoor rotenburo and a sauna.
Insider tip — Shinto Village lies at the foot of Mt. Haruna — one of Gunma's great volcanoes whose summit caldera contains Lake Haruna, famous in Japanese motorsport culture as the mountain road backdrop of the Initial D manga/anime series about drift racing. The JGSDF Sousagahara tank exercise area occupies the plateau. Fureaikan (community exchange hall) onsen serves the farming communities of this quietly distinctive village where volcanic mountain drama meets everyday rural Kanto life. The approach road through Haruna's cedar forests is atmospheric in all seasons.
