In 950, Imperial Prince Norihira was installed as the Crown Prince, but according to itsubun (a composition previously existed but doesn't exist now) of "Kyureki" (Diary of FUJIWARA no Morosue) this was decided in a secret discussion between Emperor Murakami, FUJIWARA no Onshi, Cloistered Emperor Suzaku, and FUJIWARA no Morosuke, which means that Saneyori was kept out of the loop on this decision.
天暦4年（950年）には憲平親王が立太子が決定されたが、『九暦』逸文によれば、これは村上天皇・藤原穏子・朱雀法皇・藤原師輔の密談によって決定され、逆に言えば実頼の知らないうちに決定されていたのである。
