Then Imperial Prince Kuninaga's son, Imperial Prince Yasuhito, was raised as crown prince of Emperor Kogon (Jimyoin-To Line), but in 1333 the Kamakura bakufu was ruined, and when Emperor Godaigo returned to Kyoto from Okinoshima island, accession to the throne of Emperor Kogon was cancelled, which also entailed cancellation of Imperial Prince Yasuhito becoming the crown prince.
次いで邦良親王の子・康仁親王が光厳天皇（持明院統）の皇太子に立てられるが、1333年に鎌倉幕府が滅亡し、後醍醐天皇が隠岐島から京都に還幸すると、光厳天皇の即位は取り消されて、それに伴い康仁親王も皇太子を廃された。
