In the same way, Sanyo RAI, who supported the Nancho legitimacy theory, claimed that since Emperor Gokomatsu (Northern Court (Japan)) became the legitimate Emperor because Emperor Gokameyama (Southern Court) abdicated in favor of a more virtuous successor, the Imperial succession of the Northern Dynasty should not be legitimatized because there is a problem with the legitimacy of emperors after Emperor Gokomatsu (however, the historical fact is that no ceremony for abdication by an emperor in favor of a more virtuous successor was carried out, only a ceremony to return the sacred treasures).
また同様に南朝正統論を支持した頼山陽は後小松天皇（北朝(日本)）は後亀山天皇（南朝）から禅譲を受けたことによって正統な天皇になったので、後小松天皇以後の天皇の正統性の問題を理由として、北朝の皇位継承を正当化とすべきではないと主張した（但し史実では神器帰還の儀式が行われたのみで禅譲の儀式は行われていない）。
