Osaka bag label making durable, function-first backpacks and travel gear in its own Japanese factory since 1994.



Since 2008, much of the line has been cut, sewn and finished in-house at Base Osaka, the brand's own facility, under a Made in Japan production model.
The range is built around backpacks, shoulder bags, waist packs and luggage — the label has done bags since 1994 rather than adding them to a clothing line.
Coated high-density nylon and Cordura, reinforced stitching and heavy-duty hardware sit behind the clean boxy shapes, which is where the mid-high pricing goes.

Master-piece is a Japanese bag label founded in Osaka in 1994 by Taichi Fujimatsu, built on a "Made in Japan" production model. In 2008 it opened its own manufacturing hub, Base Osaka, where much of the line is cut, sewn and finished in-house. The range centres on backpacks, shoulder bags, waist packs and luggage in coated high-density nylon and Cordura, with reinforced stitching, clean boxy silhouettes and heavy-duty hardware. Menswear-leaning but unisex, it sells through Japanese flagships and international retailers including END. and SSENSE.
