The King of Tachi: “Yamatorige Ichimonji” Replica

This is a museum-grade reproduction of the National Treasure “Yamatorige” (Sanchōmō), widely considered the greatest masterpiece of the Fukuoka Ichimonji School. Historically owned by the legendary Warlord Uesugi Kenshin, the original sword is revered for its flamboyant beauty and overwhelming power.

Authentic “Ichimonji” Geometry 

This replica faithfully captures the “Gouketsu” (Heroic/Magnificent) geometry characteristic of the mid-Kamakura period:

• Massive Proportions: With a 79cm blade length and an extraordinary 0.91cm thickness, it replicates the sheer weight and cutting power of the original battle Tachi.

• The Magnificent Curve: It features a deep 3.2cm Sori (Curvature). This extreme “Koshizori” curve is the signature silhouette of the classic Tachi, offering a majestic presence that standard katanas cannot match.

Premium Materials & Craftsmanship

• Tamahagane Replica Steel: To honor the legendary craftsmanship of the Ichimonji smiths, this blade is forged using Tamahagane Replica Steel. It recreates the subtle, natural grain (Hada) texture found in authentic Koto (Old Era) blades.

• Full Buffalo Horn Koshirae: Adhering to the highest standards of traditional mounting, all key fittings—Kashira (Pommel), Koiguchi (Mouth), and Kurigata (Knob)—are crafted from Genuine Water Buffalo Horn. This ensures a historically accurate, durable, and seamless finish.

• Japanese Leather Wrap: The handle is wrapped in Imported Japanese Leather, providing the superior grip and aging characteristics preferred by high-ranking samurai.
