Fought in present-day Higashimurayama, Tokyo at the foot of the Hachikokuyama ridge on May 12, 1333, it pitted the anti-shogunate imperial forces led by Nitta Yoshisada against the forces of the pro-Shogunate Hōjō Regency led by Sakurada Sadakuni.

The region from the east side of the Sayama Hills through the Yanagase River was the field of several battles during Japan's Sengoku period.

The chosen battlefield was a plain crisscrossed by small rivers and bordered by low-lying ridges.

The geography gave the mounted warriors room to maneuver with their commanders overlooking the battle from the surrounding ridges such as where Nitta Yoshisada raised his banner at Hachikokuyama.

[4] The result was a victory for the Imperial forces; having grown weary from two days of heavy fighting, they rested at the battlefield.
