Kokubunji, in the central western part of Tokyo Metropolis on the Chuo Line, is named for the ancient Musashi Kokubunji Temple established by Emperor Shomu in the eighth century as part of his national network of provincial temples, and the city has preserved the archaeological site of this ancient foundation alongside its modern university-town character shaped by eight educational institutions. Kokubunji Onsen Tokyo draws on chloride-rich thermal waters from the geological resources of the central western Tokyo upland, offering warm restorative baths in a university city whose ancient temple heritage, the traditional Kokubunji Hikawa Shrine, and the lively student culture create an engaging and intellectually vibrant spa setting in central western Tokyo. The Musashi Kokubunji Temple archaeological site and museum, the Nomi River natural green corridor cycling path, and the creative and independent café culture of the Kokubunji station area — known for its concentration of traditional coffee shops and independent bookstores — create a pleasantly cultured and historically layered thermal destination in western Tokyo Metropolis.
