The Divine Sword of Japan – One of the Three Sacred Treasures
A Symbol of Power, Legacy, and Imperial Divinity
The Three Sacred Treasures of Japan
Japan’s imperial lineage is said to be unbroken since mythological times, rooted in divine legitimacy. Central to this ancient heritage are the Three Sacred Treasures, known in Japanese as Sanshu no Jingi (三種の神器): the mirror (Yata no Kagami), the jewel (Yasakani no Magatama), and the sword (Kusanagi-no-Tsurugi). These objects are not merely symbols of royal regalia; they represent virtues that every ruler must possess—wisdom, benevolence, and valor.
Among these, the Divine Sword, Kusanagi-no-Tsurugi, stands out for its power, martial symbolism, and the aura of mystery that surrounds its existence. Its origins lie deep within Japanese mythology, intertwined with deities and dragons, making it both a national treasure and a spiritual totem.
The name Kusanagi-no-Tsurugi literally means "Grass-Cutting Sword", and its origin traces back to the legendary Shinto storm god Susanoo-no-Mikoto. According to the ancient chronicles Kojiki and Nihon Shoki, Susanoo slew the fearsome eight-headed serpent Yamata-no-Orochi and discovered the sword inside one of its tails.

According to the ancient chronicles Kojiki and Nihon Shoki, Susanoo slew the fearsome eight-headed serpent Yamata-no-Orochi and discovered the sword inside one of its tails.
This sword was presented to his sister, Amaterasu, the Sun Goddess, as a token of reconciliation.
Later, the sword came into the possession of a heroic prince, Yamato Takeru, who used it to escape a trap in which his enemies set fire to a field. By using the sword to cut down the burning grass and redirect the flames, he earned the name “Grass-Cutting Sword.”
Though the physical location of the sword is unknown to the public and shrouded in secrecy, tradition holds that it is kept at Atsuta Shrine in Nagoya.

Replicas are used in imperial ceremonies to represent the original.
What makes Kusanagi-no-Tsurugi particularly fascinating is that no one alive today has seen it directly. Its presence is spiritual and ceremonial, not public. During enthronement rituals of a new Japanese emperor, the sword (or its representation) is one of the core regalia bestowed upon the monarch to legitimize his reign.
Myth, Mystery, and Imperial Ceremony

During enthronement rituals of a new Japanese emperor, the sword (or its representation) is one of the core regalia bestowed upon the monarch to legitimize his reign.
It is said that the sword cannot be shown to anyone outside a select group of priests and royals. Legends warn that those who gaze upon it without permission may face dire consequences. This veil of secrecy only adds to the sword’s sacredness and mythic status.
Over the centuries, the sword has been lost, recovered, copied, and even involved in disputed historical accounts, such as during the Genpei War when it was said to have sunk with Emperor Antoku during a sea battle. Yet belief in its power persists, unshaken.
Though deeply rooted in Shinto mythology, the Kusanagi Sword also plays a key role in modern Japanese identity. Its symbolism can be seen in popular media, anime, literature, and games—reflecting Japan's seamless blend of ancient tradition with modern creativity.
