History

edit

The area of Sera was part of an ancient Bingo Province. For the Heian period, Sera was an estate and market town centered on the temple of Ryuge-ji, which belonged to the Shingon center of Mount Koya. The need to make shipments of rice to Mount Koya triggered the construction of a port in Onomichi. During the Edo Period, the area was part of the holdings of Hiroshima Domain and developed as a post town on the Iwami Ginzan Highway . Following the Meiji restoration, the area was organized into villages within Sera District, Hiroshima with the creation of the modern municipalities system on April 1, 1889. The villages of Omi, Nishi-Ota, and Higashi-Ota merged to become the town of Sera on January 10, 1955. On October 1, 2004, the towns of Kōzan and Seranishi, both from Sera District, were merged into the expanded town of Sera. After the merger, the former Sera Town Hall officially closed down and the new town hall is now located in the former town of Kōzan.

Government

Sera has a mayor-council form of government with a directly elected mayor and a unicameral town council of 12 members. Sera, together with the city of Mihara contributes three members to the Hiroshima Prefectural Assembly.

Although it has a population of less than 20,000, it is also a transportation hub, so it is the center of commerce in the central Bingo region with large supermarkets, home appliance mass retailers, and home centers. In addition, the highlands in the town are relatively cool in the summer, and are attracting attention as a summer resort because of its convenient transportation.
