When he, as Sodaisho (commander-in-chief), attacked Iwaya-jo Castle defended by Joun TAKAHASHI in 1586, his troops suffered as many as 4000 casualties by desperate counterattack on the part of only less than 800 Johei (castle garrison), which, in addition, ended up giving time for the troops of Hideyoshi TOYOTOMI to land upon Kyushu shores.
