This situation did not differ during TAIRA no Masakado's War (930-931) or in the Revolt of TAIRA no Tadatsune (1028-1031) a hundred years later because several neighboring provinces became 'ruined provinces' after the Revolt of TAIRA no Tadatsune and the imperial court had to exempt kanmotsu (tribute goods paid as taxes or tithes) for four years in order to recover.
この状態は、平将門の乱（930-931年）から100年後の平忠常の乱（1028-1031年）においても変わらず、それが故に平忠常の乱は近隣数ヶ国が「亡国」となり、朝廷はその復興の為に4年間も官物を免除しなければならなかったほどである。
