Kamikochi Onsen sits within or near the famous Kamikochi alpine resort in Nagano Prefecture, one of Japan's most celebrated highland landscapes, where the Azusa River flows beneath the jagged peaks of the Northern Japan Alps in a glacially carved valley designated as a special natural monument and national park scenic area. The spring provides naturally heated thermal waters in one of the most dramatically scenic settings available to any onsen in the Japanese archipelago, where the grandeur of the surrounding alpine environment — towering peaks, pristine river, and ancient forests — amplifies the restorative experience of immersion in geothermal water. Kamikochi Onsen invites visitors to complement their experience of Japan's most iconic mountain landscape with the deeply human tradition of warming both body and spirit in the earth's naturally heated mineral waters.
Insider tip — Kamikōchi Onsen sits in the celebrated Kamikōchi highland valley — one of Japan's most beautiful alpine landscapes, a pristine river valley at 1,500 metres surrounded by the soaring peaks of the Northern Japan Alps, accessible only by bus to protect its pristine environment. The sulfurous springs draw on the volcanic geology of the Hotaka range, allowing bathers to soak amid one of Japan's most magnificent mountain settings, where the clear Azusa river flows beneath 3,000-metre peaks in the Chubu Sangaku National Park.
