The Ministry’s table gives this block 19 seats. That is the block, not this prefecture alone.

Where this page sits

The regional tier in this release is the prefecture. Municipalities do not have pages yet. The single-member districts, the proportional block, and the Councillors’ district are linked below.

Article 92 says the organisation of local public bodies is fixed by law under the principle of local autonomy. Article 93 says each has an assembly and that residents directly elect the chief executive and the assembly members. The Ministry describes separate elections for prefectural governors, prefectural assembly members, municipal mayors, and municipal assembly members.

District index

Government

Gap. The governor’s name, the assembly’s party totals, and the next polling day are not printed here. The sources read on 17 October 2026 say the chief executive and the assembly members of a local public body are elected, and that an election caused by the end of a term is held within 30 days before the term ends. Those sources do not print each prefecture’s term-end date.

Municipalities

Gap. Municipality pages are not in this release. House single-member districts, proportional districts, and Councillors’ districts open from the district index. Article 93 of the Constitution says a local public body has an assembly and that residents directly elect the chief executive and the assembly members.
