## History

The area of Genkai was part of ancient Hizen Province. During the Edo period, the area was part of Karatsu Domain. Following the Meiji restoration, the villages of Chika and Ariura, were established with the creation of the modern municipalities system. The two villages merged on September 30, 1956 to form the town of Genkai. On December 31, 1957 the neighborhoods of Sosorogawachi, Yunoo, Fujihira, Tashiro from the village of Kirigo were incorporated into Genkai. Kirigo's remaining neighborhoods are incorporated into Karatsu.

### The great Heisei merger

All other towns and villages from Higashimatsuura District were incorporated into Karatsu between 2005 and 2006. Genkai originally planned to merge into Karatsu with the rest of the district, but was concerned about the slow administrative response of the surrounding areas. Eventually they withdrew their decision to merge and decided to continue as an autonomous municipality.

## Government

Genkai has a mayor-council form of government with a directly elected mayor and a unicameral city council of ten members. Genzai, collectively with the city of Karatsu, contributes six members to the Saga Prefectural Assembly.

## Economy
