Chofu, in the central western part of Tokyo Metropolis, is a significant city on the Keio and Seibu railway lines known as the location of Tokyo Racecourse — one of Japan's largest and most famous thoroughbred horse racing tracks — and the historic gateway to the Kyodo family shopping district and the Jindaiji district whose ancient temple and surrounding soba noodle restaurants create one of Tokyo's most charming temple-town neighbourhood experiences. Chofu Onsen Tokyo draws on sodium and bicarbonate thermal waters from the geological resources of the western Tokyo plain, offering restorative baths in a city whose racing culture, traditional Jindaiji temple neighborhood, and easy Keio Line access to Shinjuku create a pleasantly varied urban spa destination in central western Tokyo. The Tokyo Racecourse and its sweeping grandstands, the Jindaiji Temple — one of Tokyo's oldest Buddhist foundations — and the row of traditional soba restaurants in the Jindaiji temple approach street create a delightfully diverse and historically layered spa destination in the western Tokyo Metropolis.

Insider tip — Chofu is home to the Jindai Botanical Garden and a thriving sento scene fed by bicarbonate aquifers beneath the Musashino Plateau. The slightly elevated 41°C temperature suits the cooler months when Chofu's parks turn to russet and gold, and locals file in from the Keio Line platforms to decompress. The soft alkaline water is particularly valued for eczema-prone skin and is a reason many residents choose the sento over home bathing. Visit on a Sunday morning before the botanical garden opens for a quietly meditative double experience.
