Tonosawa Onsen has prospered as one of the seven hot springs in Hakone since the Edo period. At the end of the suspension bridge of the Hayakawa River, which flows through the ravine between Tanomine and Yusakayama, there is a one-house inn called "Yama no Chaya" surrounded by a deep bamboo grove. Rooms with elaborate views of nature in the four rich seasons. All of the baths, including the atmospheric open-air bath, are filled with hot water from a private source, and the colors of the four seasons spread out on the plates of carefully selected kaiseki cuisine. The murmuring of the clear stream and the seasonal breeze blowing through the bamboo grove. Enjoy a quiet time while admiring the bright moon floating in the mountains.
