The was the first defeat suffered by Takeda Shingen, and the first field battle in Japan in which firearms were used. It took place in Shinano Province or the modern-day Nagano Prefecture.
Battle
The Battle of Uedahara was part of Shingen's attempt to control Shinano Province. Shingen's father had invaded the territory and the clan was already in control of the bulk of its southern region around Lake Suwa. Shingen's campaign began with the takeover of Shika castle, which alarmed Murakami Yoshikiyo due to its proximity to his territories. Shingen, on the other hand, adhered to the traditional battle strategy and failed to use the tanegashima first. Around 700 of Takeda's men were killed, including Itagaki, and two other generals, Amari Torayasu and Hajikano Den'emon. Shingen himself even suffered a spear wound to his left arm. On the other hand, Shingen benefited from the conflict, expanding his power further as he gained the Kousaka, Inoue, Mennai, Suda, Takanashi, and Seba districts.
