Sujiyu Onsen Senshakuyu

A tiny community bath tucked down a grassy path near Sujiyu Onsen, you might easily walk past it. It runs on an honor system: drop some coins in the box and you have the place to yourself. The lukewarm, slightly metallic water fills a simple rock bath, and moss that grows on the stones drifts in the water, giving it a wild, unhurried feel.
