Toshimitsu was from Mino province and a long-time retainer of Akechi Mitsuhide, though he at first served Saitô Yoshitatsu. He was considered a competent soldier. According to one version of events, he was captured after the Battle of Yamazaki and executed. Another theory has that he killed himself the day after the battle. Toshimitsu's daughter was the well-known Kasuga no Tsubone, who would be a nurse for the later shôgun Tokugawa Iemitsu.
