The Japanese Emperor is the ceremonial head of state in Japan and is part of the country's long-standing imperial family. The role is largely symbolic, with the Emperor performing various ceremonial duties and representing Japan at official events. The current Emperor, Naruhito, ascended to the throne in May 2019, following the abdication of his father, Akihito. The Japanese imperial family is considered the oldest continuing hereditary monarchy in the world, with a lineage that dates back over a thousand years. The Emperor's powers are defined by the Constitution of Japan, which emphasizes the Emperor's role as a symbol of the state and the unity of the people, rather than a governing authority.
