Shrines and Swords—From Sacred Tools to Divine Objects
In Japan, swords have been more than mere weapons; since ancient times they have been revered as "sacred treasures" possessing divine power. The Kusanagi Sword (Ama no Murakumo no Tsurugi), one of the Three Sacred Treasures, is widely known as a symbolic example, but throughout the country, countless other swords are enshrined and stored in shrines, with their total number said to reach tens of thousands.
The reasons why swords are dedicated to shrines are diverse. There are various reasons.
- Gantou: Swords offered by warriors departing for battle to pray for victory
- Houshatou: Swords dedicated as gratitude for safe return
- Acts of pure faith by offering the finest works to the divine
In the aristocratic society of the Heian period, the dedication of swords to influential shrines such as the Ise Shrine became an established form of ritual practice.
Types and Historical Transitions of Dedicated Swords
Swords dedicated to shrines can be broadly divided into three categories.
- Goshintaitou: Enshrined as the body of the deity, usually kept deep within the inner sanctum away from public view
- Shinpoutou: Managed as treasures of the shrine, sometimes displayed during festivals and special occasions
- Honoutou: Swords brought and dedicated by believers, most commonly stored in treasure vaults
Historically, sword dedications by the samurai class reached their peak during the Kamakura and Muromachi periods. Multiple records document swords dedicated to Tsurugaoka Hachimangu by Minamoto no Yoritomo, and these dedications included political intent to demonstrate the shogunate's authority before the gods. During the Edo period, regular dedications by the shogunal and daimyo families became systematized, and renowned swords were offered annually to prestigious shrines such as Ise Shrine, Kasuga Taisha, and Sumiyoshi Taisha.
The Reality of Modern Dedication Procedures
In contemporary Japan, the possession of swords requires a registration certificate based on the "Law Regulating Possession of Firearms, Swords and Daggers," and the handling of this certificate is important in shrine dedications. Dedication forms are broadly divided into two types: "permanent dedication" and "temporary dedication."
| Form of Dedication | Transfer of Ownership | Required Procedures |
|---|---|---|
| Permanent dedication | Ownership transfers from dedicator to shrine | An "owner change notification" must be submitted to the prefectural board of education, and the shrine is registered as the new owner. The shrine, as a legal entity, can be registered as the owner on the certificate |
| Temporary dedication (custodial dedication) | No transfer | Name change procedures are unnecessary. However, if the custodial arrangement extends over a long period, the shrine may be held responsible for safekeeping, so it is advisable for both parties to prepare a custody receipt or storage agreement |
Storage and Maintenance of Dedicated Swords
The storage condition of swords dedicated to shrines varies greatly depending on the shrine's size and financial resources. Large shrines store swords in specialized treasure vaults with controlled temperature and humidity, but in small shrines simple storage in wooden boxes is not uncommon.
Sword preservation requires periodic "oil reapplication" (abura-biki) and "wiping" (nugui). A thin coating of clove oil or camellia oil is applied to prevent rust, and deteriorated oil must be regularly removed, otherwise rust develops and damages the blade. However, shrine priests do not necessarily possess specialized knowledge of sword preservation, and cases where swords are discovered in poor condition decades after dedication are not rare.
To address this issue, the Nippon Bijutsu Katana Hozon Kyokai (NBTHK) conducts sword preservation lectures and touring guidance for shrines throughout the country. Additionally, restoration efforts utilizing subsidies from the Agency for Cultural Affairs are underway, and swords designated as Important Cultural Properties receive government-funded restoration.
Issues Surrounding the Return of Dedicated Swords
Cases exist where swords dedicated to shrines are later demanded to be "returned" in subsequent generations. The most common are return requests by descendants of the dedicators, but legally, since ownership has transferred, the shrine has no obligation to return them. However, from an ethical perspective or to maintain relations with believers, shrines sometimes respond voluntarily.
More complex are issues surrounding swords "requisitioned" by the military from shrines during wartime. In the final stages of the Pacific War, numerous swords were confiscated from shrines throughout the country, but some that were not melted down were confiscated and lost overseas after the war. Negotiations for the return of such dedicated swords continue today, and some have been realized through diplomatic channels.
In recent years, the treatment of swords from defunct shrines has also become an issue. In unmanned shrines without priests, dedicated swords sometimes remain without anyone knowing of their existence. These swords, which should be protected as regional cultural assets, are left in abeyance with unclear ownership and management responsibility, creating challenges from administrative and cultural heritage protection perspectives.
Transmission of Sword Culture Through Dedicated Swords
The practice of dedicating swords is not merely a religious act but has played an important role in transmitting Japanese sword culture to future generations. Through multiple crises—warfare, iconoclasm, and postwar confiscation—swords stored in shrine treasure vaults have generally continued to be protected.
Among contemporary swordsmiths, many view shrine dedication as the highest form of craftsmanship. Offering a commission-made sword to a shrine means that the swordsmith's skill and spirit are permanently preserved before the gods, giving it significance in a different dimension from swords that are bought and sold.
The culture of dedicated swords continues vibrantly today, with new dedications occurring annually at shrines throughout the country. Particularly during the relocation ceremony (sengu), it is customary for new swords to be dedicated, and during the Ise Shrine's Great Sengu, the creation of dedicated swords by contemporary swordsmiths has been carried out. The deep connection between swords and Shinto belief continues to be inherited unchanged across the ages.
