## History

The area of Nishimera was part of ancient Hyūga Province. In the early 15th century, the Mera clan, who are said to be descendants of the Kikuchi clan, moved to the area and ruled 14 villages surrounding Mount Mera, constructing Ogawa Castle in present-day Ogawa, hamlet as their stronghold. The area came under the control of Hitoyoshi Domain during the Genna era (1615-1624) and remained part of that domain to the Meiji restoration of 1871. In 1872, it was transferred to Koyu District in Mimitsu Prefecture (predecessor of Miyazaki Prefecture). Due to this historical background, the Mera region has stronger ties with the Kuma region of Kumamoto Prefecture (Higo Province) than other regions of Miyazaki Prefecture. With the creation of the modern municipalities system on May 1, 1889, the villages of Nishimera a Higashimera were created. Higashimera was incorporated into Saito city and Kijo town in 1962 when the Hitotsuse Dam was constructed, but the borders of Nishimera remain as established in 1889.
