It is located in former Mino Province in what is now Akasaka neighborhood of the city of Ōgaki, Gifu Prefecture, Japan.

The area was known in the Edo Period for its lime kilns producing quicklime for use as fertilizer, and for its marble processing industry.

The village of Akasaka was at an intersection of the Nakasendō with a road to the Buddhist temple of Kegon-ji, the 33rd and final stop on the Saigoku Kannon Pilgrimage.

Per the 1843 "中山道宿村大概帳" (Nakasendō Shukuson Taigaichō) guidebook issued by the Inspector of Highways (道中奉行, Dōchu-būgyō), the town had a population of 1129 people in 292 houses, including one honjin, one waki-honjin, and 17 hatago.
