Overview
ISAMU KATAYAMA BACKLASH was founded in Tokyo in 1999 by Isamu Katayama, following roughly fourteen years of work in bag manufacturing and leather production. The label first grew through Japanese select-shop wholesale, opened its own Daikanyama store in 2003 and entered the international market with buyer exhibitions in Milan and Paris in spring 2004. Leather craft, material processing and direct knowledge of manufacturing formed the basis of the house before its reputation spread internationally.
The collection system developed through seasonal lookbooks, product catalogues and advance order exhibitions, with gallery presentations providing an early international framework. BACKLASH staged its first domestic runway for the twentieth-anniversary event BACKLASH NIGHT II DECADES in Tokyo in 2019. From 2020 the seasonal rhythm became especially clear, combining the main Spring/Summer and Autumn/Winter cycles with a recurring 2nd programme for specialist lines and collaborations.
Katayama remains the label’s designer and is also named as the responsible person for BACKLASH Inc.’s online store. The active structure includes the high-end made-to-order BACKLASH The Line, the denim-specialist BACKLASH THE DENIM and the long-running BACKLASH XX Yohji Yamamoto programme. By 2026 the brand operates direct retail in Tokyo and Osaka, maintains further officially designated flagship locations, supplies a broad Japanese dealer network and selected US retailers, and ships internationally through its own e-commerce operation.
Philosophy
BACKLASH is built around the behaviour of leather after construction. Its defining garment-dye process, seihin-zome, begins with a completed garment made from undyed or lightly prepared hide, then subjects the piece to dyeing, washing, shrinkage and related treatments. The leather contracts around fixed metal hardware, creating buckled zipper lines, compressed surfaces and irregularities that make the production process visible in the finished garment.
Katayama’s material vocabulary ranges from Japanese calf and steer to Italian shoulder leather, Guidi, Maryam and Horween hides, with treatments chosen for the structure and response of each skin. The Line carries this material focus into exotic leathers and 925 silver hardware; THE DENIM applies abrasion, repair and leather contrast to jeans. Riders jackets remain central, joined by leather trousers, fabric garments, footwear, bags, jewellery and small leather goods.
Ageing is designed into the clothing. Vegetable tanning, garment dyeing, colour transfer, abrasion and patina allow the surface to keep changing through wear, and the house’s year-round material development gives familiar forms a long technical life. BACKLASH repeatedly revisits silhouettes, hides, hardware and finishing methods, using variation in construction and wear as a source of visual change across the collection system.
