A solitary inn standing at 1,100 meters above sea level, where you can relax in a stunning semi-open-air bath overlooking the Asama mountain range

Gunma Tsumagoi Village

"Tsumagoi Prince Hotel" is a quiet resort hotel nestled on a highland 1,100 meters above sea level in Tsumagoi Village, Agatsuma District, Gunma Prefecture. It offers Motoshirane Onsen, a natural hot spring highly rated by the Japan Spa Association and various rankings, in an open, roofed semi-open-air bath with a superb sense of spaciousness. From the bath, guests can take in sweeping views of the majestic ridgelines of the Asama mountain range, including Mount Asama and Mount Asamayama, one of Japan's 100 Famous Mountains, and enjoy this high-quality hot spring to the fullest while gazing at the sunset-lit mountains and the star-filled night sky overhead, all of which make it easy to stay warm after bathing.

Hot Spring & Bath Information

Motoshirane Onsen Roofed Semi-Open-Air Bath

TypeNatural Hot Spring

A roofed semi-open-air bath where the refreshing highland breeze at 1,100 meters above sea level flows pleasantly through. The water is filled with Motoshirane Onsen, a high-quality natural hot spring known for its skin-beautifying effects and for its salt content, which clings to the skin to help retain warmth and make you less likely to cool down after bathing. Directly in front of you stretches a magnificent panorama of Japan's 100 Famous Mountains, including the Asama mountain range and Mount Asamayama. At dusk, you can be soothed by the sunset turning the sky a deep crimson, and at night by a star-filled sky that seems to pour down from above.
