We collaborate with domestic and overseas original-yarn manufacturers and major material manufacturers, and handle yarns and fabrics that are suited for innerwear. Furthermore, we plan and sell products with various designs that make use of functional materials, including our own independently developed materials. We carry out the processing of yarns and fabrics and the sewing of products at subcontract factories in Asia, and at our own sewing factories (Nisshin Kohgyo Corporation / Sophia Corporation) in Japan. The main purchasers are major domestic and overseas apparel manufacturers, and mass-merchandise stores.

In collaboration with material manufacturers and processing plants, we supply yarns and products suitable for socks and legwear to major apparel and sock manufacturers both in Japan and overseas.
At our processing and sales company in Pinghu, China, we carry out yarn processing and production.
In Japan, in addition to yarn sales, we also engage in OEM and ODM production of finished products, as well as sales of licensed products from overseas brands.

Furthermore, our group company, GSI ABROS Co., Ltd., mainly conducts OEM and ODM transactions for socks and innerwear — planning and proposing products for major mass retailers and specialty select shops — and develops a product business centered on American brands.
