Battle of Mikatagahara
By the time Takeda Shingen was 49 years old, he was the only "daimyō" with the necessary power and tactical skill to stop Oda Nobunaga's rush to rule Japan. He engaged Tokugawa Ieyasu's forces in 1572 and captured Futamata, and in January engaged in the Battle of Mikatagahara, where he defeated the combined army of Nobunaga and Ieyasu, but not decisively. After defeating Tokugawa Ieyasu, Shingen stopped his advance temporarily due to outside influences, which allowed the Tokugawa to prepare for battle again.
