The Battles of Kawanakajima were a series of fierce conflicts during Japan's Sengoku period, waged between Takeda Shingen of Kai Province and Uesugi Kenshin of Echigo Province from 1553 to 1564. These battles centered around the strategic Kawanakajima plain, lying between the Sai and Chikuma rivers in northern Shinano Province, now within Nagano City. The rivalry began when Shingen took control of Shinano, forcing Ogasawara Nagatoki and Murakami Yoshikiyo to seek refuge with Kenshin, prompting repeated clashes.
There were five major battles: Fuse in 1553, Saigawa in 1555, Uenohara in 1557, Hachimanbara in 1561, and Shiozaki in 1564. The most notable of these was the Battle of Hachimanbara on October 18, 1561, which unfolded in the heart of the Kawanakajima plain and saw brutal casualties on both sides. Despite the intensity of these conflicts, neither Shingen nor Kenshin managed to secure definitive control of Kawanakajima.
These battles became iconic in Japanese military history, symbolizing valor, chivalry, and the tactical mastery of the Sengoku period. They are celebrated in Japanese literature, art, and popular culture for their dramatic and relentless nature.
Historical Background
Shingen initiated his campaign in Shinano in 1541, advancing in 1550 to capture several castles from Ogasawara Nagatoki, who fled to Murakami Yoshikiyo. Following intense skirmishes, Shingen forced Murakami out of his strongholds, taking Katsurao Castle in 1553, which led to Kenshin’s intervention and the subsequent battles.
The Major Battles
- First Battle of Kawanakajima (1553): Known as the Battle of Fuse, Shingen marched through Kawanakajima, reaching as far as the Chikumagawa River’s eastern bank, where he encountered Kenshin. Although initially repelled, Shingen pressed forward, defeating scattered Murakami forces, while Kenshin retreated before winter.
- Second Battle of Kawanakajima (1555): Also called the Battle of Saigawa, Shingen set camp south of the Sai River, while Kenshin held the east. The Kurita clan, allied with Shingen, supported him from Asahiyama fortress. Despite Kenshin’s repeated attempts to take this fortress, the armies eventually disengaged without a decisive battle.
- Third Battle of Kawanakajima (1557): Known as the Battle of Uenohara, Shingen captured the Katsurayama fortress near Zenko-ji temple. Kenshin advanced to engage Shingen but later withdrew without a major confrontation.
- Fourth Battle of Kawanakajima (1561): The largest and most famous battle, it saw Kenshin unexpectedly descending on Shingen's forces, catching them off-guard. Kenshin’s army attacked in waves, dealing heavy casualties. Kenshin himself attacked Shingen, who famously defended himself with his war fan until aid arrived. Though Kenshin’s forces withdrew, the battle inflicted a staggering toll on both sides.
- Fifth Battle of Kawanakajima (1564): Also called the Battle of Shiozaki, this final clash involved smaller skirmishes, with both sides withdrawing after 60 days.
Despite severe losses, neither side achieved lasting control over Kawanakajima. The sustained intensity of these battles immortalized them in Japanese history, becoming revered tales of strategy and valor that encapsulate the spirit of the Sengoku era.
