Katori Jingū Treasure House

Katori Jingū is a shrine located in Katori City, Chiba Prefecture, dedicated to Futsunushi-no-Ōkami, the martial deity, and together with Kashima Jingū in Ibaraki Prefecture forms the sacred "Kashima-Katori" pair, the supreme object of veneration by warriors and martial artists throughout history. Its Treasure House, befitting a shrine to the god of war, houses numerous fine examples of Japanese swords, armor, and martial implements.

The primary reason for Katori Jingū's preeminence in Japanese sword culture is its inseparable connection to Tenshin Shōden Katori Shintō-ryū. This school of swordsmanship is one of the oldest extant martial arts traditions, founded in the middle Muromachi period by Iizasa Chōisai Ienao, and is regarded as the foundational source of many subsequent schools of swordsmanship. Katori Jingū has served as the head temple of this tradition, with votive swords offered by successive generations of masters accumulating here.

The Treasure House preserves swords and weapons donated by successive swordmasters revered as "sword saints," as well as votive offerings from martial lords closely connected to the shrine. Among these holdings are numerous swords and martial implements designated as National Treasures or Important Cultural Properties, authentically reflecting the character of a shrine dedicated to the martial deity.

The solemn main hall and precincts, standing within deep forest and surrounded by the Tone River and water village landscapes, convey to all visitors the dignity and sanctity of this sacred site of martial arts. It stands as Chiba Prefecture's foremost sacred destination for experiencing both the history of swordsmanship and the votive culture of the Japanese sword.
