## History
### Feudal period

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.
