Districts of Japan

Districts of Japan

A district (郡; gun) was the administrative unit during the period from 1890 to 1923, which is roughly equivalent to the county of the United States, and was ranked at the level below prefecture and above city, town or village.

It is still used in the Japanese addressing system to identify the location of towns or villages. Cities, unlike counties in the US, belong directly to prefectures.

Confusing cases in Hokkaido

Becase district names had been unique in the province and nowadays prefecture boundaries are roughly aligned to province boundaries, most district names are unique in the prefecture. However, the Hokkaido Prefecture, consisting of eleven provincess, involves a few confusing cases.

There are three Kamikawa Districts and two Nakagawa Districts in the Hokkaido Prefecture.

Kamikawa District (Ishikari), managed by the Kamikawa subprefecture
Kamikawa District (Teshio), managed by the Kamikawa subprefecture
Kamikawa District (Tokachi), managed by the Tokachi subprefecture
Nakagawa District (Teshio), managed by the Kamikawa subprefecture
Nakagawa District (Tokachi), managed by the Tokachi subprefecture

Abuta Disctrict, Rumoi District, Sorachi Disctrict, and Yufutsu Disctrict are deceptively similar, but each of them is a single district allotted to two subprefectures.

Abuta Disctrict, managed by Iburi subprefecture and Shiribeshi subprefecture
Sorachi Disctrict, managed by Kamikawa subprefecture and Sorachi subprefecture
Teshio Disctrict, managed by Rumoi subprefecture and Soya subprefecture
Yufutsu Disctrict, managed by Iburi subprefecture and Kamikawa subprefecture
