In the history of the Sengoku Jidai period, the Battle of Uedahara is known primarily as the first defeat of the previously undefeated Takeda Shingen, as well as the first field battle in which firearms were used.
With the fall of Shiga Castle in 1547, the entire Saku region came under the control of Takeda Shingen. In early 1548, Shingen convened a military council to determine the direction of future military expansion. His advisors pointed out that the Murakami clan was preparing for war. The Murakami began mobilizing their troops and sought to form alliances with the clans of the Saku region. At the end of 1547, Tomono Nobutoyo joined them. The situation became threatening: if no action was taken, it would be extremely difficult to control the newly conquered region. Therefore, a decision was made to launch a military campaign in the Tiiisagata region, which was owned by Murakami Yoshikiyo.
The beginning of the war
In January 1548, Murakami's troops began hostilities by invading the Saku region. Yoshikiyo's main goal was to expel Takeda's forces from these lands. In response, Shingen immediately declared a general mobilization and in early February marched out of his headquarters in Tsutsujigasaki. In Uehara, he was joined by General Oyamada Nobuari.
Despite the deep snow, Takeda's 7,000-strong army (some sources cite a figure of 10,000) crossed the Daimon Pass and reached Nagakubo Castle, where it made a brief stop to rest.
Opposing forces
If Takeda's army had managed to defeat the Murakami clan, most of the province of Shinano would have fallen under Shingen's control. However, the enemy was formidable. The Murakami clan controlled several regions and also enjoyed the support of other clans that, while not their vassals, were allied with them. Yoshikiyo mobilized vassals from various areas, and all of northern Shinano was ready to face Takeda. The Murakami army had no fewer soldiers than Shingen's.
Takeda's army set up camp on the edge of Uedahara, a large valley west of the Chikuma River. Murakami's army, approaching from the north, crossed the Muroga Pass and settled in the castle of the same name. Learning of the enemy's movements, Shingen moved his troops closer to the San River (also called Ubu), a tributary of the Chikuma River. Murakami's warriors set up camp in Iwahana. Both armies slowly drew closer, seeking to occupy the most advantageous positions for battle.
The beginning of the battle
The battle began in mid-February. Murakami's army, numbering between five and eight thousand experienced warriors, crossed the Urano River and attacked the vanguard of Takeda's army. Murakami's warriors knew the terrain well, and this played an important role in the outcome of the battle.
The commander of Takeda's vanguard, Itagaki Nobukata, formed his 3,500-strong unit into a battle formation, which some sources describe as six rows. At a signal, Itagaki's cavalry launched a powerful attack on the enemy. However, Murakami's warriors pretended to retreat and lured Itagaki's troops away from Takeda's main forces. After that, they attacked from the flanks. The maneuver caused panic, and Itagaki's soldiers fled in disorder.
Some sources claim that the Murakami used about fifty teppo arquebuses. Most likely, these were not European guns, which only appeared in Japan in 1543 and were not yet widely used, but simpler Chinese-made models. Their effectiveness was more psychological than military.
Defeat of the vanguard
Ultimately, Murakami's troops surrounded Itagaki's forces. At the same time, other positions of Takeda's army were also attacked. Oyamada Nobuari's warriors fought bravely, but were unable to turn the tide. According to some sources, even Shingen's headquarters was attacked, and he was slightly wounded.
During the battle, two senior Takeda generals, Itagaki Nobukata and Amari Torayasu, as well as Hajikano Denemon and Saima Kawatano-kami, were killed. The Takeda army suffered about 700 casualties and approximately 1,200 wounded. Shingen was forced to give the order to retreat.
Outcome of the battle
Murakami's victory was not complete and unconditional. Their losses amounted to about 350 killed and about 600 wounded. Despite their heavy defeat, Takeda's troops were not completely destroyed. They managed to avoid panic and retreat in an orderly manner.

It belonged to the type of “water castles” — mizujō — as one side of it faced Japan's largest lake, Lake Biwa, and it was surrounded by a system of moats filled with lake water, which made the fortress resemble an island.
