Kiyosu Castle is a castle that acted as a base of operations for Nobunaga Oda during the Sengoku period. It is located in the city of Kiyosu, Aichi Prefecture, Japan.
Kiyosu Castle was built between 1394 and 1427, first belonging to Yoshishige Shiba, then head of the Shiba clan and the shugo of Owari Province. Upon completion of construction, Toshisada Oda was installed in the castle as the shugodai. It is thought to have been intended as a defensive stronghold meant to protect Orizu Castle, the seat of Owari's provincial government until its destruction during battle in 1476. After the loss of Orizu Castle, the government shifted to Kiyosu, bringing prosperity to the city.
Operating from Nagoya Castle, Nobunaga Oda captured Kiyosu Castle in 1555. After Nobunaga's death, his second son, Nobukatsu Oda, came into control of the castle and began large scale renovations in 1586.
In 1610, the capital of Owari was moved from Kiyosu to nearby Nagoya on the orders of Ieyasu Tokugawa. Once a thriving castle town of 60,000 people, much of the city disappeared in what is known as the "Moving of Kiyosu."
Parts of Nagoya Castle were constructed with the use of building materials taken from Kiyosu Castle. Constructed using parts taken from the Kiyosu Castle tower, one of the names of the northwest turret of Nagoya Castle's Ofukemaru fortress is subsequently the "Kiyosu Turret."
Use of Kiyosu Castle would continue until the Edo period of the 18th century. Yoshinobu Tokugawa, a descendant of Ieyasu, was the last owner of the castle.
The original kinshachi are now in Sofuku-ji in Gifu in the neighboring Gifu Prefecture.
