Shinshun no Kago is a lodging facility that finds value in the very act of "retreating" within the forest environment of Nasu. The stay is themed around stepping away from the hustle of daily life and turning one's senses inward. All guest rooms feature semi-open-air baths, allowing guests to soak in the hot spring while sensing the presence of the forest. In the spacious rooms, guests can spend time as they wish, and the materials and color tones employ a calm quality that harmonizes with nature. The space as a whole was arranged with care for a sense of distance that blends into the surrounding nature. It creates a place where guests can confront their own time while sensing the light, sound, and presence of the wind.
