Anjo, in the southwestern Aichi Prefecture on the Yahagi River plain, is known as the 'Denma city' for its agricultural research heritage — the Anjo Agricultural Research Center established in the Meiji era conducted pioneering work on Japanese rice cultivation improvement — and for its traditional watermelon and fruit cultivation in the fertile Mikawa plain whose deep alluvial soils are some of the most productive in the Tokai region. Aichi Anjo Onsen draws on chloride-rich thermal waters from the geological resources of the southwestern Aichi plain, offering restorative baths in an agricultural research heritage city whose Mikawa plain farming culture, the Yahagi River cycling trail, and the proximity to the Toyota City automotive manufacturing corridor create a practically located spa destination in the industrial-agricultural transition zone of southwestern Aichi. The Anjo Agricultural Research heritage and the Denma Traditional Museum, the Yahagi River cycling path through the Mikawa plain agricultural landscape, and the Toyota Motor Company historic facilities accessible from the broader Mikawa region create an appealingly diverse agricultural and industrial backdrop for thermal spa relaxation in southwestern Aichi Prefecture.

Insider tip — Anjo sits at the heart of Toyota's automotive supply chain corridor in Aichi, and its sento draws sodium-chloride water from the deep Nobi Plain aquifer that underlies the region's industrial lowlands. The baths provide a deeply warming soak favored by factory workers and are often more spacious and well-equipped than their urban equivalents in central Nagoya. The city's elaborate Tanabata Star Festival in August draws visitors who often combine the event with an evening at the local sento.
