Omuro Onsen Makiba no Yu, in Nagano, offers bicarbonate water with a pH of 8, heated to 40°C. An indoor bath, an open-air outdoor bath and a sauna make up this onsen.
Insider tip — Makiba no Yu, the pasture spring, evokes the apple orchards and dairy farms surrounding Nagano city, once famous worldwide for the 1998 Winter Olympics. The soft bicarbonate spring draws from the volcanic piedmont of the Togakushi highlands and the basin of the ancient Zenkoji Temple pilgrimage.
