The Battle of Tennoji was described in "Sappan Nikki" of the Shimazu Family as follows: "Because the Sanada troop was the srongest troop in Japan, stronger than any troop in stories from ancient times, the Tokugawa army was half defeated", "Ieyasu even thought of committing seppuku", and so on.
天王寺合戦は島津家の「薩藩旧記」で「真田日本一の兵、古よりの物語にもこれなき由、徳川方、半分敗北」、「家康が切腹も考えるほどだった」などと記された。
