The ancient word Murakumo translates technically to “altocumulus clouds,” yet its poetic meaning goes far beyond a simple meteorological term. Historically, Murakumo evokes the image of a heavenly expanse where clouds gather and drift across the sky in a striking interplay of blue and white — a scene of movement, depth, and quiet grandeur suspended above the earth.
This spirit is woven directly into these jeans.
The fabric captures that atmospheric beauty through a carefully engineered interplay of slub yarns. Rich indigo-blue slub threads symbolize the vast summer sky, while irregular white slub yarns emerge between them like clouds breaking through the horizon. The alternating pattern creates a dynamic texture that feels alive — never flat, never uniform — just like the shifting sky itself. Each step, each crease, and each movement subtly changes how the fabric reveals its pattern, making the Murakumo effect something that unfolds over time.
Crafted from a substantial 17oz fabric, these jeans offer a reassuring weight and structure without sacrificing comfort. The rope-dyed indigo yarns ensure that as the denim ages, it will fade with character and nuance. High points will brighten, whiskers will form, and the contrast between sky and cloud will become even more pronounced. With wear, the fabric develops a refreshing, almost sun-washed aesthetic — a natural evolution that feels perfectly at home in the warmth of summer.
Murakumo is more than a name. It is a story told in texture and color — a piece of the sky, captured in denim, designed to transform beautifully with time.
Built in Osaka, Japan, this pair reflects everything that defines Samurai craftsmanship — substance, symbolism, and uncompromising construction.
Cut in a relaxed tapered fit with a high rise, the silhouette offers room through the top block while tapering cleanly toward the hem, striking a balance between comfort and a sharp profile. The denim itself is Samurai’s heavyweight 17oz slub fabric, spun from premium American Texas cotton. Its dramatically irregular texture — a true super slub — gives the surface depth and movement, creating a fabric that feels alive from the very first wear.
Dyed using 100% pure indigo through traditional rope-dyeing methods, the jeans are designed to evolve beautifully. Over time, the high points will brighten and the texture will become more pronounced, reflecting the philosophy woven into the piece: “Shogyo Mujyo” (諸行無常) — the impermanence of all things. Just as life is in constant motion, so too is a pair of jeans, changing and developing character with every wear.
The interior front pocket lining features a custom jacquard pattern interwoven with the words “Shogyo Mujyo,” reinforcing this deeper meaning beneath the surface.
Details throughout speak to durability and identity. Raised belt loops and reinforced stress points enhance strength where it matters most. Extra-heavy stitching ensures rugged longevity. Hammered copper rivets at high-strain areas are engraved with “サムライ” (Samurai), while the iron “Sunrise” buttons are boldly branded:
“SAMURAI CO LTD • JAPAN’S FINEST •”
The selvedge is finished with Samurai’s original white and silver lamé ID — a subtle yet unmistakable signature — complemented by a cowhide leather patch and a special Murakumo paper flasher. Each pair is one-washed, meaning no further shrinkage and a ready-to-wear fit from day one.
Every element serves a purpose. Every detail tells a story.
Strength, texture, and philosophy — woven into 17 ounces of evolving indigo.
