[1][4] Dōsan supported the marriage which allowed Nobuhide to focus on facing Imagawa Yoshimoto.

[1][4] Dōsan's head was taken by a man called Komaki Genta, a retainer of Yoshitatsu's son Saitō Tatsuoki.

His remains were originally interred in Sōfuku-ji, but they were later moved to Jōzai-ji because the Nagara River kept overflowing and covering his burial mound.

[8] Both temples are located in the city of Gifu which celebrates Dōsan with an annual festival.

Other names of Saitō Dōsan are Minemaru (峰丸), Hōrenbō (法蓮坊), Matsunami Shogorō (松浪庄五郎), Nishimura Kankurō Masatoshi (西村勘九郎正利), Shinkurō (新九郎), Nagai Norihide (長井規秀), and Saitō Sakondayu Toshimasa (斎藤左近大夫利政).
