Okutama Onsen, called Moegi no Yu, lies in Okutama, west of Tokyo, amid mountainous surroundings. Bicarbonate water at 40°C supplies an indoor bath and a rotenburo, with an on-site sauna.
Insider tip — Okutama Onsen Moegi no Yu is a scenic open-air bath nestled in the Okutama mountain valley, just 90 minutes by train from central Tokyo. The bicarbonate-rich waters soften skin beautifully and are set against views of cedar forests and the Tama River. The rotenburo outdoor bath is especially atmospheric in autumn when maple leaves turn crimson on the surrounding slopes. Arrive by the Ome Line and hike the river trail before soaking.
