Role in Games
Tadatsugu appears mostly alongside the Four Tokugawa Guardians in the Samurai Warriors series. In the first game, he first appears at Okehazama. At Anegawa, he is seen as Ieyasu's sub-officer. At Mikatagahara, he is part of the Crane formation that must be protected by Hanzō. During the Iga Crossing, Hanzo must escort Tadatsugu to meet up with Ieyasu. On Ranmaru's version of Anegawa, Tadatsugu will be part of the Anti-Oda forces for the Tokugawa and Akechi.

In the expansion, Tadatsugu is one of the Guardians that can be killed by Yoshimoto at Komaki-Nagakute.

On the second game, at Nagashino, Yukimura will be given a mission to defeat him, Ieyasu and Yasumasa Sakakibara. On the 1585 siege of Ueda Castle, Tadatsugu will send reinforcements to the disadvaantaged center only to be washed away by Toishi Castle's flood attack. On Keiji's Tournament of Champions, Tadatsugu is stationed with Yasumasa in the central garrison. For Tadakatsu's Tournament of Champions, he along with the other Guardians must hold the garrisons without being overwhelmed. On the stage Nobunaga Unites Japan, he and his cohorts try to capture Kiyosu Castle from the Oda. For Shingen's version of Nagashino, he must protect Tobigasu garrison against Tadatsugu and Mitsuhide.

In Kessen, his son Ietsugu replaces him as a Guardian having died prior to the game. However, Kessen III has him fight for Motoyasu Matsudaira.
