The Three Sacred Treasures (三種の神器, Sanshu no Jingi/Mikusa no Kamudakara) are the imperial regalia of Japan and consist of the sword Kusanagi no Tsurugi (草薙劍), the mirror Yata no Kagami (八咫鏡), and the jewel Yasakani no Magatama (八尺瓊勾玉). They represent the three primary virtues: valour (the sword), wisdom (the mirror), and benevolence (the jewel).
