Yoshina Onsen is a hot spring in Shizuoka Prefecture on the Izu Peninsula or in the Shizuoka mountain zone, one of the thermally rich regions of central Honshu where the proximity of the Philippine Sea Plate tectonic boundary generates abundant geothermal activity beneath the volcanic arc of the Izu archipelago and the mainland coastal ranges. Shizuoka Prefecture combines the iconic beauty of Mount Fuji, visible from much of the prefecture on clear days, with the rich thermal heritage of the Izu Peninsula and the Shizuoka mountain interior, making hot spring bathing a seamlessly integrated part of the regional culture of leisure and wellness. The mineral waters of Yoshina Onsen provide accessible thermal bathing to visitors and residents exploring the diverse natural and cultural attractions of this scenic central Honshu prefecture.

Insider tip — Yoshina Onsen in the central Izu Peninsula is a quiet, traditional hot-spring hamlet in the wooded hills near the Amagi mountains — the landscape immortalised in Kawabata Yasunari's celebrated novella The Izu Dancer. The springs serve a region of the volcanically active Izu Peninsula where literary heritage, lush mountain scenery, and abundant hot springs combine, in one of Japan's classic onsen landscapes within reach of Tokyo yet evoking a timeless rural Japan of forested valleys and inns.
