During the Sengoku period, Kiyosu Castle was the residence of the Oda clan (Oda Yamato no kami family), the shugo (lord of the castle), but Nobunaga Oda, who was from a branch of the clan, stole it and made it his residence. However, after Nobunaga moved his base to Gifu Castle and then to Azuchi Castle, the value of Kiyosu Castle decreased drastically. In June 1582, after Nobunaga died in the Honnoji Incident, a conference to discuss Nobunaga's successor, the so-called Kiyosu Conference, was held at Kiyosu Castle, and at this time, Toyotomi Hideyoshi decided that Nobunaga's successor would be Nobunaga's successor. Nobunaga's second son, Nobuo Oda, was appointed as the lord of Kiyosu Castle.
