Ladies and gentlemen, welcome to the website of NK Co., Ltd.

In the 20 years since our founding in 2002, we have fulfilled a wide range of customer demands through planning, design, and manufacturing, from consumer products such as fashion accessories such as bags and wallets and office equipment, to industrial products such as vehicle interiors and amusement materials. I have become. Although we were a latecomer as a manufacturer, we propose manufacturing that is not preconceived, and we have a wide range of customers, including famous overseas fashion brands, furniture brands, and major domestic automobile manufacturers. Since the beginning of 2020, the business performance has maintained an upward trend even after the corona disaster, and the sales performance in 2022 was 167% compared to the previous year. First of all, I would like to express my deepest gratitude to the community formed by suppliers and partner companies within a 30km radius from our Adachi-ku head office factory.

At NK, the current factory manager, Chixiong Zhang, was faced with financial difficulties at his place of work at the time, and he had no relatives in his home country of China. to this day. Since its founding, our company has maintained a policy of hiring and employment that does not discriminate against nationality, origin, or gender. Whether it's local housewives or foreigners, everyone has spent time improving their skills and building high quality in a diverse work environment. As a result, our "defect rate" is 0.01%.

In recent years, we have further reduced the use of molds, which is an industry custom for bag manufacturing, and have been promoting ultra-precision cutting manufacturing while minimizing the use of iron, which is a precious earth resource. In addition, we are strongly committed to building a value chain together with our customers and suppliers, with a management stance of achieving traceability of the production background for animal welfare and minimizing the disposal of scrap materials toward the realization of biodiversity. We are pushing forward.

In 2022, we will achieve a complete switch to 100% renewable energy, mainly solar power, for factory operation energy, and we are shifting to a system that contributes to carbon neutrality.

Aiming for the world's best technology, to technology that contributes to the world.

We look forward to hearing from you, who have not seen us yet.



At NK, we have created a wide variety of products such as bags, accessories, office supplies, interior goods, etc. with unconventional ideas and precise processing technology. We have a proven track record.

​In addition to consumer products, our unique technology is utilized in scenes that are difficult for people to see and industrial materials used in commercial facilities.



Based on our own policy, we thoroughly operate the following facilities.

1. LED lights are used throughout the facility. Approximately 50% lower power consumption and 40 times longer life than incandescent lamps.

2. The entire facility operates with 100% renewable energy such as domestic solar and wind power.

``Coexist with the natural environment and local communities, and make it a management goal whether or not we can fulfill our responsibilities, and make it the axis of all decision-making.''

For us, whose original business was manufacturing products such as bags using animal skins, we cannot avoid facing animals, the natural environment, and biodiversity. On the other hand, if I were to say that I was able to solve the many problems I faced as a result of my daily efforts, I would have to say that I am far from reaching that point.

How can we return the value that can only be created in the information society and globalization to the universal natural environment and our local communities? We will continue to face each other every day so that NK's manufacturing technology and experience can contribute.

■What is a company? What is a business?

Many of the phenomena that surround us are overwhelmingly not the result of the natural environment, society, and companies striking a balance. For example, although Japan is an economically developed country, the food self-sufficiency rate* is extremely low compared to other countries*, and the import penetration rate of clothing is extremely high**. We live in a world where we can hardly understand what it is.

We take full responsibility for the business model that NK builds, the day-to-day operations, and the circumstances under which the products that arise from it are produced, and through what kind of supply chain they are delivered to our customers. We will explain and provide it to you. Beyond that, we will continue to create benefits not only for our own business, but also for various stakeholders.


As NK has done so far, if your company's unique perspectives and practices bring benefits to the same industry and other industries, sharing and coexisting with them should be considered as a company's benefit. , is the true uniqueness of NK.
