Itagaki Nobukata (板垣 信方?, 1489 – March 23, 1548) was a retainer of the Takeda family. His name is also seen with different kanji as 信形.
Nobukata served under both Takeda Nobutora and Takeda Shingen and also was tasked with young Shingen. In 1541 Nobutora, along with Amari Torayasu, was driven out from the position of the head of Takeda clan, and he served as the general for Shingen often leading the troops into a battle when Shingen could not. In 1542, he would personally finish off Takato Yoritsugu at Ankokuji, shortly after the Siege of Fukuyo. In 1545, he successfully captured Takato castle. In 1546, he defeated Uesugi Norimasa at Usui Toge. With these victories, he was instrumental in gaining the control of Shinano Province and proved himself a skilled tactician. He was known as one of the "Twenty-Four Generals of Takeda Shingen".
After these victories, Nobukata increasingly became selfish and started to hold victory ceremonies without firmly winning a battle. These victories rapidly became fewer. As Nobukata was the eldest of the Takeda retainers and having educated Shingen, few could criticize his actions. In 1547, Nobukata and his troops were almost completely wiped out in a battle against the Murakami clan and without a timely rescue by Hara Toratane, Nobukata himself would have been in danger as well. Shingen offered the following waka to Nobukata to encourage him to correct his act.
In 1548 at the Battle of Uedahara, Nobutaka, satisfied with a victory, had his troops stand down to hold a ceremony. Murakami's troop regrouped and counterattacked, killing Nobutaka and Amari Torayasu.
