The following year, in March 1430, the shogunate ordered Kofuku-ji Temple to subdue Toyota in support of the Ido clan and its related Tsutsui clan but the maelstrom of war expanded, so that the Tsutsui clan and the Hashio clan both attacked the other's castle in September 1431.
翌永享2年（1430年）2月には井戸氏と同族の筒井氏を支持する幕府より、興福寺に対し豊田討伐の指示が出、更に翌永享3年（1431年）8月には筒井氏と箸尾氏が互いに相手方の居城を攻めるなど戦乱は拡大。
