District Timeline

In the cadastral reforms of the early Meiji period, on October 1, 1889, Atsumi District was divided into the town of Toyohashi and 32 villages (35 villages by 1891 due to reorganization). The village of Tahara was raised to town status on October 3, 1892, followed by the village of Okawa on June 23, 1893, and the village of Fukue on February 22, 1897. In a round of consolidation in May 1906, the town of Fukagawa was created, and the remaining number of villages was reduced from 33 to 10. Toyohashi was also raised to city status on August 1, 1906. Toyohashi annexed two neighboring villages in 1932, leaving the district with three towns and eight villages. After World War II, in another round of consolidation in 1955, the town of Futagawa was merged into the city of Toyohashi; and the town of Atsumi was created. With the elevation of the village of Akabane to town status on November 1, 1958, the district was left with only three towns.

Recent mergers
