History
The area of Yoshinogari was part of ancient Hizen Province. During the Edo Period, it was part of the holdings of Saga Domain. Following the Meiji restoration, the villages of Mitagawa and Higashi-Sefuri were established with the creation of the modern municipalities system on April 1, 1889. On April 1, 1965 Mitagawa was raised to town status. Mitagawa and Higashi-Sefuri merged to form the town of Yoshinogari on March 1, 2006. The town took its name from the remains of a Yayoi period moat-encircled village that was discovered on Yoshinogari Hill in 1986 at the site of a planned factory housing complex.
