The Ultimate Expression of Masculine Elegance in Black — A Short-Sleeve Shirt that Embodies the Beauty of Traditional Japanese Attire

In fashion, black is a timeless classic — a color that symbolizes masculinity and refined sophistication. Among all shades of black, this piece embodies a “true black” rooted in Japanese tradition.

This short-sleeve shirt, dyed with the highest-quality black used in traditional Japanese clothing, features a relaxed silhouette and exudes a unique presence through the use of traditional dyeing techniques. It’s a one-of-a-kind item that blends cultural heritage with modern wearability.

The Allure of a Short-Sleeve Shirt Dyed in Traditional Japanese Black

Key Design Features

Tailored Collar with Short Sleeves
A relaxed tailored-collar shirt that maintains an air of sophistication, perfect for effortless summer style.

Left Chest Pocket and the "Third Button" Detail
A practical and stylish left chest pocket, along with a subtly placed third button for a refined accent.

Crisp, Refined Wrinkle Texture from Garment Dyeing
The sharp creases created by garment-dyeing hemp twill add a cool, rugged edge — the very essence of masculine fashion.

Our Obsession with a One-of-a-Kind Black

This is no ordinary black. It’s a deep, profound black used in traditional Japanese garments.
The fabric is first dyed red, then immersed overnight in a high-concentration black dye solution (200–400%) and set to lock in the color.
This meticulous process ensures exceptional durability and resistance to fading, resulting in what can only be called true black.

Material & Craftsmanship: A Textile that Enhances Masculinity

Hemp Twill (Produced in Enshu)
Made from high-quality Japanese twill fabric using 21-count single hemp yarn for both warp and weft.
The natural wrinkles and cool texture of hemp make it an ideal material for summer wear.

Tough and Ages Beautifully
The more you wear it, the more character it develops — with added finishing processes enhancing its rugged charm.

Black Dyeing (Aichi Prefecture)
This shirt is dyed using the traditional craft of Nagoya Kuro Montsuki-zome, a renowned Japanese black dyeing method.
Passed down through generations, this technique brings out the deepest and most beautiful shades of black.
