Hiking in Tokachidake Onsen

A return trip up Tokachi-dake (2077m), an active volcano and one of Japan's Hyakumeizan (100 Famous Mountains), will take six to eight hours return (16km) and reveal some marvellous volcanic landscapes – if you're lucky enough to get clear weather.

About 40 minutes in, the trail splits, with one branch heading up to the Tokachi-dake summit and another veering south to Furano-dake (富良野岳; 1912m); the 9.5km return trip up the latter will take four to six hours.
