Enjoy an extraordinary retreat surrounded by tranquility at this Onsen accommodation, a renovated traditional house perched above the river in the Hoshio village.

Hoshio Hamlet, tucked deep in Nammoku Village at the far western edge of Gunma Prefecture, is a true hidden retreat where Japan’s nostalgic original landscape still remains. Traditional farmhouses over 100 years old (former sericulture homes) still stand here, and the stone walls built by earlier generations create a remarkable scenery. The “Shiomizu Mineral Spring” (local name), once used as the hamlet’s public bathhouse, was revived as Hoshio Onsen through the efforts of villagers and supporters from outside the village. The bath attached to each Room features free-flowing hot spring water from Hoshio Onsen (piped directly from the source). Its reddish, golden-hued water warms you to the core and leaves your skin smooth—an Onsen known for its beautifying qualities. Tateiwa: A 40-tatami total pure Japanese-style Room with two connected 12-tatami rooms (24 tatami), surrounded by a three-sided veranda corridor + private open-air Onsen bath for guests Hoshio: A 20-tatami Western-style Room with an 8-tatami living area plus two 6-tatami bedrooms finished with solid hinoki wood for a natural woody fragrance + private open-air Onsen bath for guests Hoshiogawa: A 10-tatami Western-style Room with views of the Hoshiogawa River right in front of you + private Onsen rock bath for guests (the tub is tiled—a symbol of Showa-era romance) Step away from city crowds, immerse yourself in silence filled only with murmuring streams and birdsong, soak in Hoshio Onsen, gaze at the stars at night, and enjoy a truly extraordinary escape. <Hot spring quality of Hoshio Onsen> Sodium-Calcium Bicarbonate-Chloride Cold Mineral Spring (Hypotonic Neutral Cold Mineral Spring)
