japanese regalia
The Imperial Regalia of Japan (三種の神器 Sanshu no Jingi / Mikusa no Kandakara), also known as the Three Sacred Treasures of Japan, consist of the sword Kusanagi (草薙劍 Kusanagi no Tsurugi), the mirror Yata no Kagami (八咫鏡), and the jewel Yasakani no Magatama (八尺瓊曲玉). The regalia represent the three primary virtues: valor (the sword), wisdom (the mirror), and benevolence (the jewel).
Due to the legendary status of these items, their locations or appearance are not confirmed, but it is commonly thought that the sword is located at Atsuta Shrine in Nagoya, the jewel is located at Kōkyo (the Imperial Palace) in Tōkyō, and the mirror is located in the Ise Grand Shrine in Mie Prefecture.
