Akiu Onsen (秋保温泉) is a hot spring resort located in Akiu-cho, Taihaku Ward, Sendai City, Miyagi Prefecture, and is one of the representative hot springs of the Tohoku region. Despite being just a 30-minute drive from central Sendai, it is surrounded by abundant nature and is affectionately known as “Sendai’s Hidden Hot Spring Resort.”
An Ancient Hot Spring with Over 1,500 Years of History
The history of Akiu Onsen is ancient, with its opening dating back approximately 1,500 years. A legend remains that during the reign of Emperor Kimmei, the 29th emperor, it healed ailments in the imperial court. It is sometimes counted as one of the “Three Most Famous Hot Springs in Japan” alongside Arima Onsen in Hyogo Prefecture and Dogo Onsen in Ehime Prefecture.
During the Edo period, it flourished as the official hot spring of the Sendai clan’s Daimyo Date family, with successive lords visiting for hot spring therapy. After the Meiji period, it opened to the general public and developed into one of Tohoku’s leading hot spring tourist destinations.
