Oda Nobunaga was not pleased that Toshimitsu chose to work under Mitsuhide, and if not for Mitsuhide's intervention Nobunaga would have killed him.

Toshimitsu was also vital for the Akechi action at Honnō-ji and the Battle of Yamazaki.[3]

He was the father of the Lady Kasuga, who became a preeminent retainer of the Tokugawa Shogunate.[3]
