Gokayama Onsen Gokasansou

Gokasansou is a ryokan with an indoor bath and an open-air rotenburo facing the valley, plus a sauna; men's and women's baths are kept separate. The spring, drawn from the foot of Mount Ningyo (人形山), runs cooler than bathing temperature and is warmed before it reaches the tubs. The inn sits in Gokayama, the Toyama valley known for its UNESCO-listed gassho-zukuri (合掌造り) thatched-roof villages. Reviewers mention grilled river trout and Gokayama tofu on the dinner table, and the inn is a common stop for people touring the valley's thatched-roof hamlets.
