Kazuma-no-yu 檜原温泉センター「数馬の湯」
A village onsen an hour by bus from Musashi-Itsukaichi, closed only on Mondays.
The public hot-spring complex of the village of Hinohara, the only municipality in Tokyo that is neither a city nor a district (mura). The spring is simple alkaline, with an indoor bath, an outdoor bath and a sauna; the in-house restaurant offers local dishes, including soba with maitake mushrooms. It is the terminus of the bus from Musashi-Itsukaichi, the last station on the JR Itsukaichi Line, about an hour's journey: the westernmost point of Tokyo reachable by regular scheduled transport.
