Manza Onsen
万座温泉
A hidden highland spa at about 1,800 meters. Its sulfur content ranks among the highest in Japan, and its milky-white outdoor baths overlook snowy mountains.
Manza Onsen lies on the western foot of Mount Kusatsu-Shirane, at an elevation of about 1,800 meters. It is one of Japan's highest hot-spring resorts. Its waters are acidic sulfur springs with very high sulfur content, giving them a milky-white color. Many inns have outdoor baths facing the mountains, and soaking in snow in winter is especially spectacular. Manza Ski Resort is nearby. The Sorabuki geothermal area has fumaroles to see. It takes about 30 minutes to drive from Kusatsu Onsen. In winter you need to enter from Tsumagoi via the Manza Road. Buses also run from JR Manza-Kazawaguchi Station, but they are infrequent.
Opening hours
Day-trip bathing approx. 10:00–15:00 (varies by inn)
