Kusanagi-no-Tsurugi: The Divine Sword of Atsuta Shrine
Deep within the verdant embrace of Atsuta-no-Mori in Nagoya lies a treasure that has defined the spiritual backbone of Japan for millennia. Atsuta Jingu, or Atsuta Shrine, is not merely a place of worship; it is the sanctuary of the Kusanagi-no-Tsurugi, the legendary “Grass-Cutting Sword.” As one of the Three Sacred Treasures of Japan (the Imperial Regalia), this sword bridges the gap between the mythological age of gods and the modern imperial lineage. While the sword itself remains hidden from human eyes, its presence imbues the shrine with a profound sense of power and mystery.
Origins of the Sacred Treasure
The Kusanagi-no-Tsurugi holds a status in Japanese history that is comparable to Excalibur in Arthurian legend, yet it is treated with a religious reverence that far exceeds simple folklore. The sword is part of the Imperial Regalia of Japan (Sanshu no Jingi), alongside the mirror Yata-no-Kagami (housed at Ise Grand Shrine) and the jewel Yasakani-no-Magatama (kept at the Imperial Palace).
According to tradition, these items serve as the physical proof of the Emperor’s divine ancestry. The sword represents the virtue of valor. While historians debate the physical nature of the artifact—speculating whether it is a bronze or iron blade from the Yayoi period—its symbolic weight is undeniable. It was enshrined at Atsuta Jingu roughly 1,900 years ago, making the shrine one of the most significant Shinto sites in the country, second only to Ise Jingu.
The Legend of the Serpent and the Prince
The mythology surrounding the sword is detailed in Japan’s oldest chronicles, the Kojiki and the Nihon Shoki. The story begins not with a samurai, but with the storm god, Susanoo-no-Mikoto.
The Slaying of Yamata no Orochi
After being banished from the heavens, Susanoo encountered an elderly couple weeping over the fate of their daughter, who was to be devoured by the eight-headed serpent, Yamata no Orochi. Susanoo devised a plan to intoxicate the beast with sake. Once the serpent fell into a drunken stupor, Susanoo hacked it to pieces. When he cut into the creature’s tail, his own blade chipped, revealing a brilliant sword hidden within the flesh. He named it Ame-no-Murakumo-no-Tsurugi (Sword of the Gathering Clouds of Heaven) and presented it to his sister, the sun goddess Amaterasu.
Yamato Takeru and the Fire
Generations later, the sword was gifted to the legendary warrior prince Yamato Takeru. During a treacherous campaign in the eastern lands, the prince was lured into a trap by a warlord who set the surrounding grassland on fire. Desperate, Yamato Takeru used the divine blade to cut away the burning grass and discovered the sword had the power to control the wind. He turned the flames back onto his enemies and survived. From that day forward, the blade was known as Kusanagi-no-Tsurugi—the Grass-Cutting Sword. Following the prince’s death, the sword was enshrined at Atsuta, where it remains to this day.
Modern Culture and Significance
In contemporary Japan, the Kusanagi sword occupies a unique space between religious artifact and pop-culture icon. It gained international attention during the enthronement of Emperor Naruhito in 2019, where the Imperial Regalia (or their replicas/stand-ins) played a central role in the accession rituals.
Beyond the solemnity of imperial rites, the sword appears frequently in modern media. From anime like Naruto and One Piece to video games like Final Fantasy, references to the Kusanagi sword and the Yamata no Orochi myth are ubiquitous. This constant reinvention keeps the ancient legend alive for younger generations, proving that the sword’s cultural sharpness has not dulled over the centuries.
However, at Atsuta Jingu, the atmosphere remains strictly traditional. The sword is never put on public display. It is kept deep within the shrine’s innermost sanctum (Hongu). This invisibility amplifies its mystique; pilgrims pray not to an object they can see, but to the invisible presence of the deity residing within the sword.
Traveler’s Tips for Visiting Atsuta Jingu
Visiting Atsuta Jingu is a serene escape from the urban bustle of Nagoya. Here is how to make the most of your pilgrimage:
- Access: The shrine is easily accessible via the Meitetsu Line (Jingu-mae Station) or the JR Line (Atsuta Station), just a few minutes south of Nagoya Station.
- The Treasure Hall: While you cannot see the Kusanagi sword, you can visit the Bunkaden (Treasure Hall), which houses over 4,000 other historical artifacts, including ancient swords, mirrors, and documents that offer context to the shrine’s history.
- Culinary Delight: Do not leave without trying Kishimen (flat noodles) served at the restaurant on the shrine grounds. It is a local Nagoya specialty.
- Walk the Nobunaga Wall: Look for the tall earthen wall donated by the warlord Oda Nobunaga in 1560 after his miraculous victory at the Battle of Okehazama, for which he prayed at this very shrine.
