Sanshu ni jingi 三種の神器, also known as Mikusa no Kandakara, are the Imperial Regalia of Japan and consist of the sword Kusanagi (草薙劍), the mirror Yata no Kagami (八咫鏡), and the jewel Yasakani no Magatama (八尺瓊曲玉 or 八坂瓊曲玉). They symbolise the primary values of courage, wisdom and benevolence, as well as the Imperial family’s divine descent from Amaterasu.
They are regarded as legendary and sacred to Shintoism and are therefore kept concealed from the public in separate locations, said to be the Atsuta Shrine (熱田神宮 Atsuta-jingū) in Nagoya for the sword, either the Imperial Palace in Tokyo or Meiji Shrine (明治神宮 Meiji jingū) for the mirror, and the Ise Grand Shrine (伊勢神宮 ise jingū) for the jewel.
The jewel and the sword were last seen in public in 1989, when the current Emperor Akihito ascended to the throne, and again in 1993 during the actual enthronement, albeit on both occasions wrapped and therefore shrouded from view.
The term sanshu no jingi is sometimes used to describe amenities of modern life, such as the refrigerator, the washing machine and the vacuum cleaner in the 1950s or the “three Cs” in the 1970s (colour television, car and cooler).
