District Timeline

In the cadastral reforms of the early Meiji period, on October 1, 1889, Nukata District was divided into one town (Okazaki) and 26 villages. The village of Fukuoka was raised to town status on November 8, 1893, followed by Hirohata village on May 13, 1895. In a round of consolidation in May 1906, the remaining number of villages was reduced from 24 to 15. The town of Hirohata was annexed by Okazaki on October 1, 1914. Okazaki attained city status on July 1, 1916. The village of Iwazu became a town on September 1, 1928 and later the same year, three neighboring villages were annexed by Okazaki, leaving the district with two towns and 11villages. Following World War II, on April 1, 1952 the village of Kōta gained town status. On August 1, 1954 the village of Toyosaka (from Hazu District) was merged into the town of Kōta. The towns of Iwazu and Fukuoka, and the villages of Motojuku, Yamanaka, Fujikawa, Ryudani and Tokiwa were merged into the city of Okazaki on February 1, 1955; and on September 30, 1956, the villages of Toyotomi, Miyazaki, Katano, and parts of Shimoyama were merged to form the town of Nukata. Despite pressure from the central government, on November 14, 2003 Kōta declined to participate the Okazaki-Nukata Region Merger Conference. As a result of this Conference, on January 1, 2006 Nukata
