Nakadanaso was founded in 1898. A secluded Accommodation in Komoro, Shinshu, with ties to the literary master Toson Shimazaki. Inspired by the founder’s vision, the building is wooden throughout, offering the warmth of natural timber. Our natural Onsen, fed directly from our own source and flowing freely, is known for its gentle, silky feel and skin-beautifying qualities. Guided by the belief, “Is there not a way to make oneself more fresh—and more simple?”, we welcome you with heartfelt hospitality. Leave the bustle of everyday life behind and enjoy a relaxing stay as you reflect on history and savor the nostalgic charm of Shinshu.

The Hotel boasts natural Onsen with eight types of baths and two types of saunas for men and women respectively. Room types are abundant, including single, twin, double, Japanese-style, and Japanese-Western-style rooms, accommodating groups and parties. Located just 10 minutes by car from Saku-Daira Station on the Hokuriku Shinkansen or the Saku IC on the Joshinetsu Expressway, and only 30 minutes by car to the popular Karuizawa, our hotel offers excellent accessibility as a base for business and sightseeing.

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.
