According to "the Records of the Oda Family," he took the tonsure in his later years and called himself Urabo (浦坊) (which is rare as a Kaimyo [posthumous Buddhist names], and one opinion states that it is a transcription of his Christian name), and it is said that he died of Hansen's disease in Kyoto in the Bunroku era.
信秀の晩年については『織田家雑録』によれば、晩年は剃髪し、浦坊（戒名としては珍名の部類に入るらしく、洗礼名を音訳したものとの説がある）と号した、文禄年間、京都でハンセン病のために病死したとされる。
