小牧・長久手の戦い
From 1558–1573, the castle lord was Sassa Narimasa's subordinate. When the Battle of Komaki and Nagakute occurred in 1584, Ikeda Tsuneoki came there. After the war, Toyotomi Hideyoshi stayed at Jōjō Castle. The founder of Higashikasugai, Mayor Hayashi Kimbei, lived here during the Meiji period.
