伯耆伝
Hōki Tradition
A distinctive regional sword tradition from Hōki Province (modern Tottori Prefecture). The master smith Yasutsuna is credited with forging Dōjigiri Yasutsuna, one of the Five Greatest Swords of Japan and considered by many the finest surviving Japanese sword. The Hōki tradition represents an independent regional development in the formative period of the Japanese sword.
Description
Hōki Province and the Formative Period of the Japanese Sword
Hōki Province (modern western Tottori Prefecture) sits in the Sanin region with abundant tatara iron-sand deposits along its river valleys. The Hōki sword tradition developed independently of the five major Gokaden traditions and represents an important regional current in the very formative period of the Japanese sword's emergence—roughly contemporaneous with the transition from straight blades to curved tachi.
Yasutsuna and Dōjigiri Yasutsuna
The Hōki master Yasutsuna (active late Heian, c. 990–1030) forged what many consider the finest surviving Japanese sword: Dōjigiri Yasutsuna, one of the Five Greatest Swords (Tenka-Goken) and a National Treasure housed in the Tokyo National Museum. Named for the legend of the warrior Minamoto no Yorimitsu slaying the demon Shuten-dōji with this blade, the sword embodies the archaic Heian ideal of the Japanese tachi: deep koshi-zori, ko-kissaki, and a ko-itame jigane with a flowing, ancient hamon. After nearly a millennium, its aesthetic perfection remains undiminished.
Continuation: Aritsuna and Mamori
The subsequent Hōki smiths Aritsuna (believed son or disciple of Yasutsuna) and Mamori extended the tradition into the early Kamakura period. Their works are transitional, combining late Heian forms with early Kamakura developments. Confirmed signed works are extremely rare and designated Cultural Properties.
Decline and Legacy
The Hōki tradition contracted as the major Kamakura schools expanded. However, the Sanin region's iron-production culture—culminating in the Izumo tatara system—remained vital through the modern era, indirectly sustaining all of Japanese swordmaking. For students of early Japanese sword history, the Hōki tradition is indispensable—a window onto the founding moments of Japanese sword art.
Characteristics of This Era
- Among the oldest surviving Japanese swords — Yasutsuna's works document the transition from straight blades to curved tachi in the formative period of the Japanese sword
- Deep koshi-zori and ko-kissaki — the archaic Heian ideal; functional and aesthetic perfection in the same form
- Ancient jigane and hamon — ko-itame with a primitive, archaic hamon distinct from the later refined Gokaden schools; iron quality from Hōki tatara smelting of extraordinary durability
- Mythological resonance — Hōki swords are bound to demon-slaying legends; they embody the Japanese sword as spiritual object rather than mere weapon
