Jūji Kikkō Fuchi Kashira 十字龟甲

Fuchi-Kashira “Jūji Kikkō” ｜ White Copper (Cupronickel) Sword Fittings with Crossed Tortoiseshell Pattern

The Jūji Kikkō fuchi-kashira set is crafted from white copper and features a meticulously engraved geometric pattern based on the traditional Japanese kikkō motif. Inspired by the hexagonal structure of a tortoise shell, the design incorporates distinctive cross-shaped elements within each cell, creating a refined variation known as Jūji Kikkō, or “Crossed Tortoiseshell.” In Japanese culture, the tortoise has long been regarded as a symbol of longevity, protection, and steadfast endurance. The repeating hexagonal arrangement reflects balance, strength, and harmony, while the intersecting cross motifs add visual depth and architectural precision. The contrast between the darkened recessed background and the polished raised lines further accentuates the intricacy of the pattern, giving the fittings a timeless and dignified character. Widely associated with samurai aesthetics, traditional armor, and classical decorative arts, the Jūji Kikkō motif conveys resilience and permanence. Its clean geometry and understated elegance make this fuchi-kashira set particularly well suited to both formal koshirae and historically inspired sword mountings.
