The Imperial Regalia of Japan are three ancient objects associated with the Imperial House of Japan: the Kusanagi Sword, the Yata-no-Kagami and the Yasakani-no-Magatama. They exist in real life, but are housed in sacred Japanese shrines and almost never seen in public. However, as national treasures of Japan, many replicas of them do exist. Actually, some of the objects themselves are believed to be replicas of older versions that have since been lost or destroyed.
