The Formation of Saikai City

A significant turning point in the region's history occurred on April 1, 2005. To streamline local administration and foster regional growth, several towns within the Nishisonogi District underwent a merger—a process where multiple local governments combine to form a single, larger administrative unit.

Ōseto joined forces with four other neighboring towns to create the new city of Saikai. The participating municipalities included:

  • The former town of Saikai
  • Ōshima
  • Sakito
  • Seihi

This merger transformed the local governance structure, integrating the diverse communities of the Nishisonogi District into one unified city. Today, the area remains a part of the broader Saikai City administration, maintaining the historical connections established by these former towns.
