# Imperial Regalia of Japan

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). The actual historical status of these legendary treasures is unknown as they are intentionally kept from public view to symbolize authority.
Representations of the regalia are used in masakaki in many Shinto rituals.

## Legend

According to legend, these treasures were brought to Earth by Ninigi-no-Mikoto, legendary ancestor of the Japanese imperial line, when his grandmother, the sun goddess Amaterasu, sent him to pacify Japan. These treasures were eventually said to be passed down to Emperor Jimmu, who was the first Emperor of Japan and Ninigi's great-grandson. Traditionally, they were a symbol of the emperor's divinity as a descendant of Amaterasu, confirming his legitimacy as paramount ruler of Japan. When Amaterasu hid in a cave from her brother Susanoo-no-Mikoto, thus plunging the world in darkness, the goddess Ame-no-Uzume-no-Mikoto hung the mirror and jewels outside the cave and lured her out of hiding. Upon emerging from the cave, Amaterasu was so startled by her reflection in the mirror that it gave the gods an opportunity to extract her. Susanoo later presented the sword Kusanagi to Amaterasu as a token of apology; he had obtained it from the body of an eight-headed serpent, Yamata no Orochi.
At the conclusion of the Genpei War in 1185, the six-year-old Emperor Antoku and the Regalia were under the control of the Taira clan. They were present when the Taira were defeated by the rival Minamoto clan at the Battle of Dan-no-ura, which was fought on boats in the shallow Kanmon Straits. Although there are some medieval texts relating to the loss of the sword, which variously contended that a replica was forged afterwards, or that the lost sword itself was a replica, or even that the sword was returned to land by supernatural forces; replicas of the sword and mirror were actually made as early as the 9th century, and the original sword is considered entrusted to Atsuta Shrine in Nagoya. The importance of the Imperial Regalia to Japan is evident from the declarations made by Emperor Hirohito to Kōichi Kido on 25 and 31 July 1945 at the end of World War II, when he ordered the Lord Keeper of the Privy Seal of Japan to protect them "at all costs".

## Role

Since 690, the presentation of these items to the Emperor by the priests at the shrine has been a central element of the enthronement ceremony. This ceremony is not public, and these items are by tradition seen only by the Emperor and certain priests. While their actual locations are not confirmed, it is commonly thought that the sword is located at the Atsuta Shrine in Nagoya, the jewel is located at the Three Palace Sanctuaries in Kōkyo (the Imperial Palace in Tokyo), and the mirror is located at the Ise Grand Shrine in Mie Prefecture. Their first post-World War II enthronement appearance occurred during the accession and enthronement of Akihito in 1989 and 1990. Aside from their presence during the abdication of Akihito on 30 April 2019, their latest appearance occurred during the enthronement of Emperor Naruhito. He formally took possession of the regalia in a brief ceremony on 1 May 2019. The items themselves were never revealed during these public occasions as they remained shrouded from view in packages or boxes.
When these items are not being used for their ceremonial purpose, their supposed locations are kept off limits to the public. Mikael Adolphson, a professor at Cambridge University, stated that this hidden strategy "adds mystique, and thus, authority, to the objects." He went on to say that Shinto religious tradition is "especially protective" of its symbols. There is a general reluctance in Japan to allow a historical analysis of the regalia as such an assessment could potentially "de-mythologize" the items.
Scholars consider the imperial regalia to represent the fusion of Japan's ancient indigenous groups with new arrivals. The three treasures are a symbol that the emperor should unite the ethnic groups without discrimination.
