Sagamiko Onsen Ururi, near Lake Sagamiko in Sagamihara, Kanagawa Prefecture, offers sodium-chloride thermal water at 40°C, with an indoor bath, an outdoor rotenburo and a sauna.
Insider tip — Lake Sagami (Sagamiko) is a reservoir formed by damming the Sagami River in the Tanzawa foothills — beloved by Tokyo day-trippers for its spectacular spring cherry blossom illuminations and winter light festival (Sagamiko Illumillion, one of the largest in the Kanto region). The Tanzawa-Oyama Quasi-National Park frames the lake on three sides with forested ridges. Sagamiko Onsen Ururi provides the perfect post-illumination soak on chilly winter evenings.
