Kusanagi - Folklore

Folklore

Although the sword is mentioned in the Kojiki, this book is a collection of Japanese myths and is not considered a historical document. The first reliable historical mention of the sword is in the Nihonshoki. Although the Nihonshoki also contains mythological stories that are not considered reliable history, it records some events that were contemporary or nearly contemporary to its writing, and these sections of the book are considered historical. In the Nihonshoki, the Kusanagi was removed from the Imperial palace in 688, and moved to Atsuta Shrine after the sword was blamed for causing Emperor Temmu to fall ill. Along with the jewel and the mirror, it is one of the three Imperial Regalia of Japan, the sword representing the virtue of valor.

Kusanagi is allegedly kept at Atsuta Shrine but is not available for public display, and its existence cannot be confirmed. During the Edo period, a Shinto priest, claimed to have seen the sword. According to him, the sword was about 84 cm long, shaped like calamus, fashioned in a white metallic color, and well maintained. Another record claims that this priest died from the curse and the power of the sword, but this is most likely a story that was spread to emphasize its power. Recently, Japan's nationally run broadcasting station, NHK, went to Atsuta Shrine to videotape the sword but were turned away.

In The Tale of the Heike, a collection of oral stories transcribed in 1371, the sword is lost at sea after the defeat of the Heike clan in the Battle of Dan-no-ura, a naval battle that ended in the defeat of the Heike clan forces and the child Emperor Antoku at the hands of Minamoto no Yoshitsune. In the tale, upon hearing of the Navy's defeat, the Emperor's grandmother led the Emperor and his entourage to commit suicide by drowning in the waters of the strait, taking with her two of the three Imperial Regalia: the sacred jewel and the sword Kusanagi. The sacred mirror was recovered in extremis when one of the ladies-in-waiting was about to jump with it into the sea Although the sacred jewel is said to have been found in its casket floating on the waves, Kusanagi was lost forever. Although written about historical events, The Tale of the Heike is a collection of epic poetry passed down orally and written down nearly 200 years after the actual events, so its reliability as a historical document is questionable.

According to some records, the Tenth Emperor, Emperor Sujin, is reported to have ordered the fashioning of a replica of Kusanagi. However, this information was reportedly only made public after it was known that the sword had been stolen. The imperial household claimed that it was the replica which was stolen, but it is just as likely that the replica was made after the fact to replace the irrecoverable sword. Sujin is considered a "legendary Emperor" by historians because there is insufficient evidence to assign him to a historical period.

Another story holds that the sword was reportedly stolen again in the sixth century by a monk from Silla. However, his ship allegedly sank at sea, allowing the sword to wash ashore at Ise, where it was recovered by Shinto priests.

Due to the refusal of Shinto priests to show the sword, and the rather sketchy nature of its historical references, the current state of or even the existence at all of the sword as a historical artifact cannot be confirmed. The last appearance of the sword was in 1989 when Emperor Akihito ascended to the throne, the sword (including the jewel and the Emperor's two seals) were shrouded in packages.
