About Cohérence

The wardrobe of legends

Cohérence's outerwear draws inspiration from legendary artists and intellectuals like Albert Camus, Le Corbusier, Marcel Duchamp, and Léonard Foujita, blending the best of the past with the latest technology.

Designer Kentaro Nakagomi's love for Surrealism, Jazz, and “Nouvelle Vague” cinema is reflected in the beautiful modern classics collection, crafted with a high level of Japanese craftsmanship. Cohérence's fabrics are developed in-house, including the "Tweed Chevron Jersey," made with rare knitting machines and a blend of four types of wool.

The collection showcases Japanese attention to detail, featuring real horn buttons, a lining motif designed after a Jean Cocteau’s shirt or very practical storm pockets.
All overcoats are made entirely in Japan.
