MasterCraft Union is a Japan-based luxury apparel brand that was started by Hiroyuki Yoshikawa in 2014. The brand embraces elements like vintage Americana, Western wear, utilitarian aesthetics, and military-inspired styles in their pieces, creating a diverse plane for opportunity and creation. MasterCraft Union's brand ethos is based on Takumi: the pursuit of mastery through relentless dedication and attention to detail. The brand's Takumi artisans approach their work with a deep respect and testament to their lineage.

The brand's primary focus is their selection of Japanese denim. Each piece is handcrafted in Okayama, Japan by denim artisans using premium cotton sourced globally. The lands of Okayama stand as a beacon for textile craftsmanship, dating back to the 19th century, making it the optimal location for denim-making. Additionally, indigo dyeing holds a rich history in Okayama. MCU's artisans use traditional dyeing techniques to yield color depth and richness that sets the fabric apart from any other.
