About
A wild hot spring (yato, 野湯) on the slopes above Toushichi Onsen (藤七温泉), with no facilities at all. The water surfaces naturally in open pools and runs a murky grayish-green from sulfur. The surrounding ground has active steam vents, and the adjacent Saiunso (彩雲荘) facility has posted warnings about burn risk in the area.
