Hachioji, in the western Tokyo Metropolis at the base of the Okutama mountain range, is the largest city by area in Tokyo with a population of over 600,000, home to twenty-one universities making it one of Japan's highest-density student cities, set where the Kanto plain meets the Tama foothills in a landscape of traditional silk weaving heritage and modern university culture. Hachioji Onsen Tokyo draws on chloride-rich thermal waters from the geological resources of the western Tokyo volcanic zone at the Kanto mountain fringe, offering restorative baths in a major western Tokyo city where the Hachioji matsuri festival — one of Tokyo's largest summer festivals with enormous painted festival floats — and the traditional Hachioji ori silk weaving craft create a distinctively cultural spa setting. The spectacular Hachioji Matsuri festival floats in August, the Shoin Jinja shrine commemorating loyalist scholar Yoshida Shoin, and the gateway access to the Okutama mountain wilderness — Tokyo Metropolis's surprisingly wild western mountain landscape — create a rewarding and accessible spa destination in western Tokyo.
