History[edit]
Sakai is within ancient Hizen Province.
The city of Saikai was established on April 1, 2005, from the merger of five towns on the northern tip of Nishisonogi Peninsula: the former town of Saikai, Ōseto, Ōshima, Sakito and Seihi (all from Nishisonogi District). Its city hall is the former town hall of Ōseto.
Government[edit]
Saikai has a mayor-council form of government with a directly elected mayor and a unicameral city council of 18 members. Saikai contributes one member to the Nagasaki Prefectural Assembly. In terms of national politics, the city is part of the Nagasaki 4th district of the lower house of the Diet of Japan.
Economy[edit]
The economy of the towns in this area were dominated by fishing and whaling in the Edo period, and coal mining in the Meiji period. The area is now primarily agricultural, with forestry products and tourism also of importance. However, on Oshima island, north of Saikai and close to Sasebo, a large shipyard is active building bulk ships and metal structures, i.e. Oshima Shipbuilding, in which the Sumitomo Heavy Industries has shares.
Education[edit]
Saikai has 11 public elementary schools and six public junior high schools by the city government, and three public high schools operated by the Nagasaki Prefectural Board of Education. The prefecture also operates one special education school for the handicapped.
