Hakata Onsen (Ganso Motoyu), in downtown Fukuoka City, heats its sodium-chloride water to 41°C. An indoor bath, an outdoor rotenburo bath and a sauna are on offer.
Insider tip — Hakata Onsen Ganso Motoyu, the original pioneer source spring of Hakata, serves the ancient merchant city heart of Fukuoka famous for Hakata-ori silk weaving, Hakata doll ceramics, and the Hakata Gion Yamakasa festival where giant decorated float teams race through the old merchant streets in a July celebration of extraordinary communal athleticism. The Hakata thermal aquifer draws from the Chikuzen coastal sedimentary basin beneath one of Japan most dynamic commercial cities.
