Tennou

The term tennou (天皇) is the Japanese word for the Emperor of Japan. It literally translates to "heavenly sovereign." The tennou is the head of state and the ceremonial head of the Imperial Family of Japan. Historically, the position of tennou was believed to be divinely descended from the sun goddess Amaterasu, making the emperor a living god.

The current role of the tennou is defined by the post-World War II Constitution of Japan. In this constitution, the tennou is designated as the "symbol of the State and of the unity of the People." He has no political power and his duties are primarily ceremonial, such as appointing the prime minister and chief justice of the Supreme Court, promulgating laws, and receiving foreign ambassadors. The tennou also performs important religious rituals and ceremonies associated with the Imperial Family and Shinto traditions.

The Imperial Household Agency manages the affairs of the tennou and the Imperial Family. Succession to the Chrysanthemum Throne follows a hereditary line, with the eldest son traditionally inheriting the title. The current tennou is Naruhito, who ascended to the throne in 2019. The institution of the tennou has a long and continuous history, making it one of the oldest monarchies in the world.
