Kamakura Shirts’ Shirt

Today, it is said that clothing sewn in Japan accounts for less than 1.5% of all apparel distributed in the country. In such an environment, Kamakura Shirts has remained committed to domestic production since its founding. Not only in sewing, but from the fundamental processes of craftsmanship—such as material selection, thread making, and fabric development—we collaborate with outstanding Japanese manufacturers in pursuit of truly one-of-a-kind shirts.

What lies at the heart of this philosophy is delivering shirts that can be worn with peace of mind and cherished for years to come. That, to us, is the true meaning of “Made in Japan.”

Japanese Craftsmanship

The true strength of domestic production lies in our direct connection with both makers and customers. By hearing their voices firsthand, we can respond quickly, this is the unique value of producing in Japan. Most of all, creating together with people who share a love for Japanese craftsmanship brings us joy. That passion is why we continue to insist on domestic production.

The Finest Shirts Begin with the Finest Materials

At Kamakura Shirts, every shirt starts with exceptional fabric. We travel the world to source only materials we believe in, knowing that the finest cloth brings out the best in our craftsmen.

Today, we’re also cultivating domestic cotton in Japan, connecting timeless craftsmanship to the next generation.

Thread

Every great shirt begins with a single strand. At Kamakura Shirts, we spin the world’s finest raw materials into exceptionally high-quality yarn typically two-ply 80s count or higher, with select shirts crafted from ultra-fine 400s count.

Only threads that meet our strict standards are used, ensuring hidden craftsmanship that delivers everyday comfort.

Fabric

Shaping the ideal through every step. From dyeing and weaving to finishing, we work closely with Japan’s specialized mills to ensure each fabric defines the shirt’s character. Seasonal colors, thread density, and subtle luster are all carefully considered, with master craftsmen overseeing every detail. The result? A shirt that delights every time you choose to wear it.

Sewing

Every stitch blends craftsmanship and design. Our artisans transform premium fabrics into shirts that captivate, using patterns and techniques mastered by only a few factories in Japan. The result is a perfectly balanced silhouette with three-dimensional beauty and exceptional comfort.

Natural Shell Buttons
A true mark of quality, our shirts feature natural shell buttons. Most are crafted from Takase shell, prized for its soft luster and effortless feel. For our luxury line, we use white mother-of-pearl, the same shell that creates pearls, with a brilliance that rivals fine jewelry. Even in the smallest details, Kamakura Shirts’ dedication to craftsmanship shines through.

 

Interlining That Complements the Fabric
The collar defines a shirt’s character, and the interlining brings it to life. From the advanced floating interlining used in fine tailoring to the carefully selected fusible interlining in our easy-care shirts, we choose only the highest quality to ensure a natural look. Each fabric is matched with the interlining that best enhances its unique qualities.

 

Finer Stitching
While most shirts use around 18 stitches per 3 cm, Kamakura Shirts are sewn with 21. The result is a sharper, more elegant look with added durability. Each shirt embodies the skill, time, and dedication of true craftsmanship.

Flat-Felled Seams
Our shirts feature flat-felled seams, where the inside fabric edges are fully enclosed. This labor-intensive technique doubles the stitching for unmatched durability, a smooth feel, and a clean, polished finish. Unlike typical overlocked seams used in mass production, our method ensures both comfort and elegance inside and out.

The Pinnacle of Mass Production

Since 1993, Kamakura Shirts has crafted high-quality shirts with one guiding principle: deliver authentic quality at a fair price. Even in a small store, founder Yoshio Sadasue believed success comes from the product and service, not location.

Our shirts feature ultra-fine yarns, flat-felled seams, and natural shell buttons—every detail designed for comfort, durability, and understated elegance. Made entirely in trusted Japanese factories, each shirt reflects decades of craftsmanship and dedication.

For over 30 years, our mission remains unchanged: create shirts that delight, surprise, and feel truly exceptional. Try one, and you’ll feel the difference.
