Futamata Onsen

Onsen group along the foothills of Mount Chausu, with Nasu-Yumoto's milky sulfur waters at its heart.

Aizu-Wakamatsu's traditional onsen quarter, founded in the 8th century. Ryokan packed along the Yukawa river gorge below Tsurugajo castle.

Eleven onsen districts strung along a 9-km gorge of the Hoki River in Tochigi. Wide range of spring chemistries within a tight valley.

Quiet gorge onsen at the confluence of the Kinu and Kawaji rivers in Tochigi, just upstream of bustling Kinugawa. The local saying "Kawaji for cuts, Kinugawa for ailments" nods to its gentle alkaline waters and traditional yutoji feel.
