A total of eight items utilizing Brewed Protein™ fiber (four dress shirts and four denim trousers) designed by the Yohji Yamamoto brands Yohji Yamamoto Collections and Y’s will be launched exclusively in collaboration with Isetan Mitsukoshi and showcased at a pop-up store within the Nihombashi Mitsukoshi Main Store from April 17–30, 2024.

For Yohji Yamamoto Collections, the two denim trousers and two dress shirts utilizing fabric made with Brewed Protein™ fiber are timeless designs that combine Yohji Yamamoto’s style and functionality. These items are intended to be incorporated into the wearer’s daily wardrobe and worn for a long time.

Y’s will release two cotton shirts using their iconic broadcloth and two denim trousers. All four garments feature a cactus flower print with distinctive brush strokes.

This collection, launched under the theme of “connecting to the future”, serves as a continuation of Mitsukoshi’s 2023 “Japanese tradition” initiative, which celebrated the store’s 350th anniversary. 
Through this collaboration, Spiber hopes to increase awareness of the unique aspects of Brewed Protein™ fiber and the value it provides, as well as contribute to advancements in the world of Japanese fashion as it works toward achieving sustainable manufacturing in the future.
