In Japan there were two examples of Shosei which were, Prince Naka no Oe (Emperor Jomei and Empress Saimei's Prince, later called Emperor Tenchi or Tenji) and Emperor Jito (Emperor Tenchi's Princess, Emperor Tenmu's Empress and later called Emperor Jito), however there are some opinions that the three examples of Empress Jingu and Iitoyo no Himemiko (Princess Iitoyo) and Ahe no Himemiko (Princess Ahe) were considered as Shosei.
日本においては、中大兄皇子（舒明天皇・斉明天皇の皇子で後の天智天皇）と持統天皇（天智天皇の皇女・天武天皇の皇后で後の持統天皇）の2例を「称制」としているが、この他に神功皇后・飯豊皇女・阿閉皇女の計3例のケースも称制に相当すると言う考えがある。
