From Britain comes our red-quilting lining, our ball-chain puller fasteners, our CLIX fasteners, our cowhide leather and functional bag design. From Japan comes the PORTER nylon twill material and a functional know-how. All of the bags are made by high standard Japanese craftsman.

Yoshisa & Co., Ltd has been manufacturing bags since its establishment in 1935. They take a lot of care in every step of the manufacturing process including in the selection of material, the sewing pattern, and even the process of stitching pieces to completion.

The PORTER range began in 1962 and is one Yoshisa & Co., Ltd’s most of popular lines.
