S1956R (001R) ISHIKAWADAI RG TAPERED FIT

ISHIKAWADAI RG TAPERED. A tapered jean that carries the memory of Japan’s first denim-making era.

Reconstructing the atmosphere of the time when BIG JOHN first created jeans in Japan, the ISHIKAWADAI RG TAPERED is a special model rooted in the brand’s origin.

■ ISHIKAWADAI RG
The ISHIKAWADAI series represents one of the most meaningful chapters in BIG JOHN history.

This model is made with a deep respect for Japan-made craftsmanship, bringing together historical details, authentic fabric character, and a clean tapered fit designed for modern wear.

■ Fabric — 13oz African organic cotton denim
The fabric is a 13oz denim made with African organic cotton.

The yarn is spun using a vintage Ishikawadai spinning machine, creating a rustic and powerful uneven texture that cannot be achieved through modern uniform spinning.

The subtle irregularity of the yarn gives the fabric depth and character from the start.

With wear, whiskers, fading, and natural abrasion begin to appear, allowing the denim to develop a strong and personal aging expression over time.

■ Concept — Returning to the origin of Japanese denim
This model is intentionally made without selvedge denim, recreating the spirit of the denim BIG JOHN first produced in Japan.

Rather than simply chasing vintage aesthetics, it looks back to the true starting point of Japanese denim-making — a perspective that only BIG JOHN can bring to life.

Orange stitching against deep indigo, original buttons, a leather patch, and classic flasher details all reflect the history and identity of the brand.

Every element is designed to carry the mood of BIG JOHN’s earliest denim era into the present.

■ Silhouette — TAPERED FIT
The silhouette is a clean and versatile TAPERED FIT.

It offers comfortable room around the waist, hip, and thigh, then narrows naturally toward the hem for a neat, modern line.

While keeping the rugged character of denim, the tapered shape gives the lower leg a clean finish.

It pairs easily with sneakers, leather shoes, casual tops, shirts, and jackets, making it suitable for both relaxed and refined styling.

Wear it as a set with the matching ISHIKAWADAI RG JACKET, or break it in on its own.

The more it is worn, the more it conforms to the body, developing a personal expression that reflects time, movement, and BIG JOHN heritage.
