Sagamihara Onsen Kanagawa

Sagamihara, the second-largest city in Kanagawa Prefecture stretching from the Tama Hills to the Sagami River plain, is home to the JAXA Sagamihara Campus where Japan's space exploration satellites and deep-space probes are designed and tracked, including the celebrated Hayabusa asteroid sample-return missions. Sagamihara Onsen Kanagawa draws on chloride-rich thermal waters from the geological resources of the Sagami River valley, offering relaxing mineral baths in a sprawling suburban city that bridges the technological ambitions of the aerospace campus with the green corridors of the Sagamiko reservoir and Tanzawa mountain foothills. The JAXA campus open days, the Sagamiko Lake resort area with its famous autumn illuminations, and the Tanzawa-Oyama Quasi-National Park rising above the western city make Sagamihara a surprisingly varied destination for thermal spa visitors in the greater Tokyo-Yokohama metropolitan region.
