Notes

Kamo District (加茂郡) was one of the ancient districts of Shinano Province, but was transferred to Mikawa Province during the Sengoku period. In the cadastral reforms of the early Meiji period, on July 22, 1878, Kamo District was divided into Nishikamo District and Higashikamo District within Aichi Prefecture. With the organization of municipalities on October 1, 1889, Nishikamo District was divided into 30 villages.
