Senmatsumaru's remaining retainers and people living in his fief mourned over his death and held a memorial service for Senmatsumaru and his father with a song 'Father risked his life for the sake of his son Senmatsumaru – Be a brave man, my son.'
遺臣や領民たちは嘆き悲しみ「命すつるも子ゆえにすたれ　けなげなれとよ　千松丸」と唄い、十河父子の菩提を弔ったという。
