Tanushimaru (田主丸町, Tanushimaru-machi) was a town located in Ukiha District, Fukuoka Prefecture, Japan.
On February 5, 2005, Tanushimaru, along with the town of Kitano (from Mii District), and the towns of Jōjima and Mizuma (both from Mizuma District), was merged into the expanded city of Kurume and no longer exists as an independent municipality.
Tanushimaru was famous for its hot springs, the best being Mino Onsen, as well as its plant farming, unagi, and kappa.
Many of the local inhabitants offer cucumbers and sake to the kappa shrines.
Close ties remain with the neighboring city of Ukiha, particularly with Yoshii town.
