The siege of Arai was among the first steps taken by Hōjō Sōun towards becoming one of the most powerful warlords of Japan's Sengoku period. After attacking Kamakura in 1512, Hōjō turned to Arai castle, on a peninsula to the south, which was controlled by Miura Yoshiatsu.

Miura Yoshiatsu's son Yoshimoto, believing defeat to be inevitable, took his own life by chopping off his own head.
