Toda, directly adjacent to Tokyo across the Arakawa River in southernmost Saitama Prefecture, is internationally renowned as the home of the Toda Rowing Course, the official venue for the 1964 Tokyo Olympics rowing competition and still one of Japan's premier flat-water rowing facilities hosting national and international regattas throughout the year. Toda Onsen Saitama provides chloride-rich thermal waters from the geological resources of the Tokyo metropolitan aquifer, offering relaxing mineral baths in an urban community where Olympic sporting heritage, modern residential development, and traditional sento bathing culture exist in remarkably close proximity. The Arakawa riverside cycling paths, the Toda Olympic Boat Course Museum, and easy Saikyo Line rail access to Shinjuku in just twelve minutes make Toda an extremely convenient thermal bathing destination for visitors based in central Tokyo.

Insider tip — Toda borders Tokyo across the Arakawa River and is famous as Japan's premier rowing venue, hosting Olympic rowing events on the Toda Olympic Rowing Course. Its sento draws sodium-chloride thermal water at 40°C from deep Kanto sediments, producing the dark amber kuroyu characteristic of the region. Post-race recovery soaks are a longstanding tradition among the rowing clubs training here year-round. The proximity to Itabashi and the cycling paths along the Arakawa embankment make Toda a particularly active and sporty thermal destination.
