Hoi District, Aichi

Hoi District (宝飯郡^?, Hoi-gun) is a former rural district located in eastern Aichi Prefecture, Japan.

As of 2008 (the last data available), the district had an estimated population of 21,766 and a population density of 2194 persons per km². Its total area was 9.92 km².

Hoi District was one of the ancient districts of Mikawa province, and is mentioned in Nara period records. Originally covering all of eastern Mikawa, Shitara District to the north was separated from Hoi in 903. The district contained the provincial capital of Mikawa along with the provincial temple, both of which were located in what is now part of the city of Toyokawa. During the Sengoku period, the area was controlled by various samurai clans, including the Makino and branches of the Honda and Matsudaira clans, all of whom rose to high positions within the Tokugawa shogunate. The area was also a battlefield between the forces of the Imagawa clan and the Oda and Tokugawa clans during the late Sengoku period. In the cadastral reforms of the early Meiji period, on July 22, 1878 modern Hoi District was created, with its headquarters at Goyu-shuku, a former station on the Tōkaidō. With the organization of municipalities on October 1, 1889, Hoi District was divided into 33 villages.
