It is disputable to treat these two wars as one historical event, but both wars happened as a result of the policy by which Shonyo, the 10th chief priest of Hongan-ji Temple, and his guardian Renjun (the 6th son of Rennyo, the 8th chief priest, and also both a maternal grandfather and a grand-uncle of Shonyo) tried to strengthen the authority of hoshu (a head of a Buddhist sect).
この2つの戦いを一括りにすることの是非については、議論の余地があるものの、両者とも本願寺10世証如と、その後見人蓮淳（8世蓮如の6男で証如の外祖父であり大叔父でもある）による法主の権限強化を図った政策方針の末に生じた出来事である。
