Insider tip — 'Kasa no Yu' (傘の湯 — umbrella/hat spring) at Tamana Onsen on the Kikuchi River. Tamana is also famous for its Gyotan Onsen area and the Tamana lantern festival. The 'umbrella' name may refer to the distinctive roof architecture of this traditional bathhouse, or to the umbrella pines along the river. Tamana's sodium-chloride waters are prized for leaving skin luminously smooth — the 'bijin no yu' (beauty spring) quality.
