The Imperial Regalia of Japan consists of three sacred treasures that symbolize the legitimacy of the Japanese emperor. These treasures are the Kusanagi no Tsurugi (a sword), the Yasakani no Magatama (a jewel), and the Ame-no-Murakumo no Tsurugi (another sword). Together, they represent the emperor's divine right to rule and are essential to the enthronement ceremonies. These regalia are housed in various locations and are rarely displayed publicly. The Kusanagi no Tsurugi is associated with the mythological hero Susanoo, while the Yasakani no Magatama is linked to the sun goddess Amaterasu. The regalia are considered sacred and are integral to Japan's imperial history.
