In 1484, Amago Tsunehisa (1458–1541), was deprived of the position of Shugodai by Kyogoku Masatsune, who was the Shugo, because he did not obey the request of tax from the Muromachi bakufu, and was expelled from Gassan Toda castle. Although Enya Kamonnosuke was dispatched to Gassan Toda castle as the new Shugodai, Tsunehisa recaptured Gassan Toda castle by a surprise attack in 1486, took control of Izumo, and developed the Amago clan into a Sengoku Daimyo clan.
