Insider tip — 'Alps Kaido Hirayu' at Hirayu Onsen — one of the five Okuhida Onsengo hot spring areas in the Northern Japanese Alps (Hida Mountains) near Takayama, Gifu. The Alps Highway (Alpine Route) passes through Hirayu connecting the Matsumoto and Takayama basins across the volcanic highlands. Hirayu Onsen sits at 1,000 m elevation, with the volcanic peaks of Norikura and Yakedake visible above. The sulfurous spring waters are complemented by spectacular autumn foliage and winter powder snow — some of Japan's finest alpine skiing within reach.
