Hatonosu Gorge 鳩ノ巣渓谷

A short, dramatic river gorge on the Tama River in Okutama where emerald water swirls between granite boulders beneath a tiny suspension bridge. Locals hike it on the Okutama Mukashi-michi trail, a quieter alternative to the crowded Mitake Valley.

About

Hatonosu means "doves' nest". Legend says doves nested in a nearby shrine when the Edo-era timber workers' camp was here. Today it is a small Okutama village whose gorge is one of the prettiest spots in the Tama River valley. From Hatonosu Station, a five-minute walk leads to the Hatonosu Kobashi suspension bridge, high above blue-green pools and granite boulders. A riverside trail, part of the Okutama Mukashi-michi, heads upstream past the Shiromaru dam to Okutama Station, about 1.5 hours away and with hardly any crowds. The river is famous with locals for its autumn colours and as a summer cool-off spot. It is spectacular for a day trip within Tokyo.

Tips

Ride the JR Ome Line to Hatonosu, then walk 5 min to the bridge.
Walk upstream to Okutama Station (about 1.5 hours) and take the train back.
Don't swim. The currents are strong and the water is cold.
Peak autumn colour is usually mid-November.
