"If any daimyo posed a serious challenge to Oda Nobunaga as a potential unifier, it was Takeda Shingen of Kai Province. An able general, he had conquered all or part of the provinces surrounding his own and certainly had his sights on Kyoto. To his southwest lay Mikawa, Tokugawa Ieyasu's province. With the fall of the Imagawa clan after the Battle of Okehazama, Takeda acquired the province of Suruga while he and Tokugawa divided the province of Totomi. In 1570, Tokugawa moved his headquarters to Hamamatsu in Totomi Province, which Takeda viewed as a provocative act. What ensued was a Takeda victory over a Tokugawa force (with some Oda allies) at the battle of Mikata ga hara in 1572. In a follow-up offensive the following year Takeda Shingen died; some sources say of disease, others of a wound inflicted by a sniper at the siege of Noda Castle in Mikawa.
Takeda Shingen was succeeded by his favorite son, Takeda Katsuyori. He was a talented soldier but alienated the twenty-four generals and advisors he inherited from his father. His rejection of their advice, coupled with the belief that he was born of an enchanted mother, made his followers less than enthusiastic. Nevertheless, they followed him into Mikawa Province in 1575 even though they argued against it—there was another threat from the north, that of the Takedas' long-time adversary Uesugi Kenshin. Without their right flank, securing an invasion of Mikawa was very dangerous, even if it was a continuation of the strategy his father, Shingen, had been pursuing. However, Katsuyori had a traitor inside Tokugawa's headquarters at the castle of Okazaki, who was to open the gates to him.
Entering Mikawa from the mountains to the north, Katsuyori was marching his men toward Okazaki when he learned that his plan had been discovered and the turncoat had been executed. This turn of events convinced him not to try for the stronghold but to turn southeastward toward Tsukude, a castle he had once controlled before its commander turned his allegiance to Tokugawa. However, he then bypassed Tsukude and marched to Noda Castle on the Toyokawa River, and marched downstream toward the coast to raid three of Tokugawa's castles in the region. Katsuyori attacked and burned two minor outposts of Yoshida Castle (Nirengi and Ushikubo), but failed to take the castle itself. He then pointed his army back upriver toward the final frontier castle, Nagashino. Turnbull observes, "Possession of Nagashino was an asset worth having. It had passed from Tokugawa to Takeda and back again, and covered one of the mountain passes to Shinano … Little Nagashino would be a good consolation prize with which to conclude his Mikawa campaign."…"
