Does Japan Have Kings or Queens? No — It Has an Emperor

Japan's Monarchy: Imperial, Not Royal

Zero kings or queens. Japan's head of state is the Emperor (Tennō) — currently Naruhito (reigned since May 1, 2019).

Key Points

• World's oldest continuous hereditary monarchy (legendary 660 BC; verified ~5th c. AD).
• Constitutional role: "Symbol of State and unity of the people" (Art. 1, 1947 Constitution). No political power.
• Consort: Empress Masako. Heir: Crown Prince Fumihito. Daughter: Princess Aiko.
• No "king/queen" titles in Japanese tradition; Ō (king) used only for foreign monarchs.

Japan = Empire → Emperor. Europe = Kingdoms → Kings/Queens.
