Shogunal forces hunted down and executed the ringleaders of the Incident and recaptured the sword, but the Grand Jewels remained with the Gonancho forces who fled in 1457, the surviving retainers of the Akamatsu clan - which had been crushed in the Kakitsu Rebellion of 1441 - including Taro ISHIMI, Tatewaki NIUNOYA, and Mitsuyoshi KOZUKI, wishing to restore the Akamatsu clan's fortunes, went to the Gonancho headquarters at Kitayama near the provincial borders of Yamato and Kii Provinces (possibly referring to modern-day Kamikitayama village in Yoshino district, Nara Pref.), or perhaps at Sannoko (in Kawakami village of Yoshino district, Nara Pref.), and pretended to become vassals of the Gonancho before turning on them and striking down many of their forces, murdering Princes Jitenno and Tadayoshiten who were brothers and Imperial descendants of the Southern Court bloodline, before recapturing the Grand Jewels (in what became known as the Choroku Incident).
幕府軍によって変の首謀者たちが討たれ、剣が奪い返された後も神璽は後南朝に持ち去られたままであったが、1457年（長禄元年）に至って、1441年（嘉吉元年）の嘉吉の乱で取り潰された赤松氏の復興を願う赤松家遺臣の石見太郎、丹生屋帯刀、上月満吉らが、大和国・紀伊国国境付近の北山（奈良県吉野郡上北山村か）あるいは三之公（同郡川上村(奈良県)）に本拠を置いていた後南朝に臣従すると偽って後南朝勢力を襲い、南朝の末裔という自天王・忠義王兄弟を殺害して神璽を奪い返した（長禄の変）。
