In 1587, Hideyoshi attacked and captured Yoshihisa SHIMAZU, who was going to control Kyushu, by condemning him for having broken 'Ou Sobujirei' (peace edict for Ou region) (the subjugation of Kyushu), which meant the western part of Japan was completely under Hideyoshi's control.
そして天正15年（1587年）には九州を席捲しつつあった薩摩国の島津義久を惣無事令に違反したとして討ち秀吉の前に遂に屈服させ（九州平定）、西国は完全に豊臣氏の支配下に入った。
