Crown Prince of Teiko

The Crown Prince of Teiko (皇太子親王) is a title held by the heir apparent to the Throne of Teiko. First created by Prince Akihiro in 1899, for his son Prince Kuroko Masanori, the prince's eldest son by a royal wife Princess Akira. Prior to this, the Teikonian throne did not have a law or formal system regulating the royal succession. As of the current succession rules of the Royal House of Teiko, females, children of commoner wives or children of foreign wives are barred from inheriting the throne.

Throughout history, the powers of the Crown Prince has varied greatly. Prior to World War II, he is formally the second most powerful person in the Kingdom of Teiko. After the 1984 Teiko Constitutional Crises, the Crown Prince serves as an official liaison officer of the Royal House of Teiko to the Teikonian cabinet. Although officially invited to all proceedings, he holds no voting power and may not be given executive powers like those of the ministers of the state. However, he holds reserve power

The current Crown Prince of Teiko is Kiyoshi who is expected to fulfill his constitutional duties after his coming of age in September 2026.
