FOB FACTORY / F1147 Wide Denim 5P Pants
A modern revival of the very first denim produced in Japan in the 1940s.
Crafted using FOB’s expertise and modern looms, this 13.75oz selvedge denim faithfully recreates Japan’s earliest domestically produced denim, featuring a deep indigo hue and rich texture. Like “new vintage,” it develops unique fading and wear patterns over time, gradually becoming a one-of-a-kind pair of jeans.
While designed with a wide silhouette, the waist and hips are carefully tailored, creating a clean, stylish shape without excess bulk.

FOB FACTORY
A Japan-made brand inspired by vintage clothing, rooted in workwear, military styles, and denim. Based in Kojima, Kurashiki City, Okayama Prefecture—one of Japan’s most renowned production hubs—all processes are carried out domestically. FOB FACTORY creates garments with the aim that, three years from now, the wearer will feel glad they chose them.

Recreating Japan’s First Domestically Produced Denim
Faithfully reproduced using FOB’s craftsmanship and modern looms, this fabric is based on the very first denim made in Japan in the 1940s.
By reviving the distinctive character of the era through advanced contemporary techniques, the result captures the feel of “new vintage” denim. With its slightly blue-toned hue and natural texture, it gives the jeans a refined and polished appearance.
Crafted from 13.75oz selvedge denim—a standard mid-weight fabric—it is finished with a one-wash treatment for immediate softness, allowing you to enjoy it from the first wear without the stiffness typically associated with raw denim.
Vintage-Inspired Details
The front features a zipper fly by UNIVERSAL, paired with donut buttons. Antique-finished metal hardware and carefully selected stitch colors reflect a thoughtful attention to detail.

A white flasher made from DuPont Tyvek is attached at the back and can be removed by cutting the stitching.
When the hem is rolled up, the signature selvedge detail—commonly known as “red ear”—appears. Its classic look adds a relaxed, understated character to the feet.
Comfort Without Compromise
Unlike traditional wide-cut jeans, the waist and hips are subtly tapered to eliminate bulk, giving the wide silhouette a clean and refined look.
A well-balanced rise ensures a comfortable, stress-free fit. With a fabric weight that is neither too heavy nor too light, this pair can be worn comfortably throughout the year.

●Staff Height / Weight: 165cm / 64kg Wearing Size: 0 Body Type: Slim Thigh Fit: Standard Fit (Waist): Just right Length: Slightly long I usually choose a size S, but for these pants, size 0 fits perfectly. The waist feels secure even without a belt, and the room from the hips through the thighs creates a relaxed silhouette. The inseam is slightly long, so at my height it creates a subtle break at the hem, adding a sense of volume. |

●Staff Height / Weight: 171cm / 70kg Wearing Size: 1 Body Type: Standard Thigh Fit: Standard Fit (Waist): Just right Length: Perfect I usually wear a size M, and size 1 offers the best fit for me. There’s no tightness at the waist, and the generous room around the hips makes it extremely comfortable to move in. The length hits just right with a slight half-break over sneakers, making it an ideal balance for a relaxed, urban style. |

●Staff Height / Weight: 177cm / 73kg Wearing Size: 2 Body Type: Standard Thigh Fit: Standard Fit (Waist): Just right Length: Perfect I usually wear a size L, and size 2 gives me an ideal fit. With an 85cm waist, there’s plenty of room and no stress around the hips. The 78cm inseam means that even at my height in the upper 170cm range, the pants aren’t too short and can be worn as a clean full-length—one of the highlights for me. |

●Staff Height / Weight: 181cm / 78kg Wearing Size: 3 Body Type: Solid build Thigh Fit: Roomy Fit (Waist): Relaxed Length: Perfect I usually choose an XL, and size 3 allows me to wear these comfortably without any sense of restriction. Even with a solid build, there’s ample room through the thighs, creating a clean drape without emphasizing body shape. The length is reassuring even for taller frames, and the balance with the hem width feels just right. |
