Mt. Mitō

Mount Mitō (Mitōsan, 1,531 m) straddles the border between Hinohara/Okutama in Tokyo and Yamanashi Prefecture, and is one of Japan’s 300 Famous Mountains.
Together with Mount Ōdake and Mount Gozen it is the highest of the Okutama Three Mountains, and its name comes from its three summits — the West, Central and East peaks. The classic day hike starts from Hinohara Tomin-no-Mori (Citizens’ Forest) at around 1,000 m and climbs through beech woods, with views of Mount Fuji opening up from the West Peak.
For public-transport access, take a Nishi-Tokyo Bus from JR Musashi-Itsukaichi Station to Hinohara Tomin-no-Mori.

The trailhead is Hinohara Tomin-no-Mori (about 1,000 m), with a free car park, toilets and a Forest Hall and other facilities. The main route is Tomin-no-Mori → Mitō Great Falls → Mount Mitō (West Peak) and back, a beginner-to-intermediate route of about 3–4 hours. It is a well-maintained loop through beech forest, and the West Peak gives a wide view toward Mount Fuji and the Southern Alps.
The best season is late April to November, from fresh greenery to autumn colours; the buses also mainly run from April to November, with no service in winter (December–February). Always check the latest trail and bus operating days before you go.

Trail Guide and Safety Notes

Route: Tomin-no-Mori → Mitō Great Falls → Buna-no-Michi (Beech Path) → Mount Mitō (West Peak 1,524 m / Central Peak 1,531 m) loop. The standard time is about 3–4 hours, an beginner-to-intermediate route. The West Peak offers views toward Mount Fuji, the Southern Alps and the Daibosatsu range.

Route-finding and slippery sections: the forest paths are well maintained, but the ridge has steep wooden steps and slippery spots. Follow the signs, and watch for mud after rain.
