A small boutique hotel with only six rooms, inspired by the forests of Kobuchizawa where the spirit of Jomon-era history still lives on.Its striking facade, appearing suddenly amid the nature of Yatsugatake, was designed by internationally acclaimed architect Atsushi Kitagawara. In a space where nature, art, and contemporary design come together, we offer time to reconnect with yourself. Each guest room features a distinct interior inspired by timeless elements unchanged since the Jomon period—light, mountains, and forest. Take in sunsets over Japan’s iconic peaks such as the Southern Alps, Yatsugatake, and Mt. Fuji from our rooftop terrace, then gaze up at a 360° canopy of stars. Soothe yourself to the core in our private open-air hot spring bath (reservation required), featuring free-flowing natural spring water direct from the source. And enjoy carefully selected whiskies at our guest-only bar while listening to the quiet of the surrounding forest...Escape everyday noise and spend an extraordinary moment of peace in nature.
