The Battle of Ozawahara (Japanese: 小沢原の戦い) was fought in 1530 in the present day Asao, Kawasaki, Kanagawa. This was the first battle for Hōjō Ujiyasu, then sixteen years old.^[1]

Ujiyasu faced Uesugi Tomooki at Ozawahara in Musashi Province. The battle was part of a seventeen-year struggle between the Hōjō clan and the Uesugi clan for control of the Kantō region which began with the 1524 Siege of Edo. The battle ended with a Hōjō victory.
