The Japanese monarchy, known as the Chrysanthemum Throne, is the oldest continuing hereditary monarchy in the world. It has a history that dates back over 1,400 years, with the current emperor, Naruhito, ascending the throne in 2019. The emperor's role is largely ceremonial, and he serves as a symbol of the nation and its unity. The monarchy is governed by the Constitution of Japan, which was enacted in 1947. This constitution defines the emperor's position as the "symbol of the State and of the unity of the people," while political power is held by elected officials. The royal family participates in various cultural and religious events, maintaining traditions that have been passed down through generations.
