There is an anecdote that Ujisato GAMO asked Hideyoshi whether he could use the 'Three-layer sedge hat' uma-jirushi (horse insignia); Hideyoshi said 'the uma-jirushi ('Three-layer sedge hat') was used by heroic Narimasa SASSA during the Siege of Odawara in 1590. You would allow to use it when you achieved appropriate feat.'
天正18年（1590年）の小田原の役で、蒲生氏郷が「三階菅笠」の馬印を使用願いたいと秀吉に申し出たところ、秀吉は「（「三階菅笠」は武勇高き）佐々成政が使用した馬印。それに相応しい手柄を立てれば使用を許そう」と言った。
