Kiyosu was the location of a post town (Kiyosu-juku) on the junction of the Nakasendō and the Minoji connecting Kamakura with Kyoto and the Ise Shrine during the Kamakura period.
In the Muromachi period, the area was fortified with the construction of Kiyosu Castle, which subsequently became a stronghold of the Oda clan and the base from which Oda Nobunaga consolidated his control over Owari Province during the Sengoku period.
After the start of the Edo period, Kiyosu Castle was dismantled by order of Tokugawa Ieyasu, and most of the population relocated to Nagoya.
By the start of the Meiji period, the area was a rural area organized into villages within Nishikasugai District of Aichi Prefecture. The town of Kiyosu was proclaimed on August 1, 1889, with the establishment of the modern municipalities system.
The city of Kiyosu was established on July 7, 2005, from the merger of the former town Kiyosu with the towns of Shinkawa and Nishibiwajima (all from Nishikasugai District).
On October 1, 2009, the neighboring town of Haruhi (also from Nishikasugai District) was merged into Kiyosu.[4]
