Japan
A river the colour of glacial flour through an alpine valley closed to private cars.
The Azusa runs the colour of glacial flour — a blue-green so vivid it looks painted on against the grey granite of the Northern Alps. Kamikōchi is a highland valley in Japan's Nagano Prefecture sealed off from private vehicles, so you arrive by bus or taxi or not at all, and the valley runs to the sound of water and wind. The Hotaka peaks wall the valley in on three sides, their snow lines visible from every clearing.
Kamikōchi sits at around 1,500 metres inside Chūbu-Sangaku National Park. The British missionary Walter Weston popularised it in the 1890s and helped make mountaineering a sport in Japan; a relief of his face marks the trailhead and a festival in his name is held each June. The Azusa River, headwater of the Shinano, Japan's longest river, rises among the Hotaka peaks, where Oku-Hotaka reaches 3,190 metres as the country's third-highest mountain. Taishō Pond was born in 1915 when Mount Yake erupted and dammed the river. The road opens in mid-April and closes in mid-November, after which the mountains reclaim the valley.
Solo
Hut-to-hut routes across the 3,000-metre peaks deliver the physical challenge that resets everything, with the valley floor as a gentle way in.
Couple
The level riverside path from Kappa Bridge to Myōjin Pond takes about an hour through scenery that needs no effort to reach — an easy shared afternoon.
Friends
A night in a mountain hut above the valley, curry rice and beer at a shared table, then a ridge at dawn — the sort of day that binds a group.
Mountain-lodge curry rice earned on the way down from the ridge — the most earned plate in Japan.
