The history of this Japanese sock brand began in 1950 just after World War II. Katsuji Nishiguchi founded the company with a single hand-operating knitting machine in Katsuragi, Nara prefecture. The brand continued to develop under succession and is currently operating under third-generation director Isato Nishiguchi. Today, Nishiguchi Kutsushita has evolved and expanded into a sock manufacturing company housing over 130 knitting machines. Their main team of professionals consists of veterans with over 50 years of experience.

The brand's catchphrase "Hakuhito omoi" conveys a deep consideration for the people who purchase and enjoy the brand's products. Everything, including the materials, designs, knitting methods and prices is thoroughly vetted. By demonstrating a commitment to high-quality natural materials and combining new and old technologies and decades of experience, Nishiguchi Kutsushita creates true timeless classics of incomparable quality and aesthetic distinction
