The siege of Akasaka was one of the earlier battles of the Genkō War between the figurehead Emperor Godaigo and the largely Hōjō-controlled Kamakura shogunate during the final years of the Kamakura period in Japan. The battle in question was fought at Shimo Akasaka-jō (下赤坂城, English: Lower Akasaka fortress), a fortress built upon Mount Yoshino near modern-day Osaka in the former Kawachi Province in Osaka Prefecture.
