Since our foundation in 1970, as an independent software company, NJK has been developing various kinds of computer systems, such as general-purpose computer, Private Branch Exchange (PBX), and so on. Our mission is to make health computer network society and we have been gaining high reputation from our customers with technical skills and the best solutions. With these achievements, we were listed on the second section of the Tokyo Stock Exchange in November 6, 2001.

Our core business is a variety field of software development, such as financial settlement systems, social infrastructure systems of traffic and communication, and embedded software development of mobile and automotive devices and home appliances. NJK group has consolidated its management structure and we have expanded the range of business areas, including sale of IT solutions and network devices, development of software packages, hardware construction and others, so that we can swiftly meet the dynamic changes of society all the time.

We made a capital and business tie-up with NTT DATA Corporation (NTT DATA), a global IT Innovator of Japan, and NTT DATA had held 50.01% of NJK stocks through Tender Offer, then NJK became a group company of NTT DATA on March 1st, 2010. Furthermore, through Tender Offer on July 2016, we delisted from the second section and became a wholly owned subsidiary of NTT DATA.

We are coping with rapid changes in the business environment with “the selection and concentration” and strengthening development of human resources. Based on our originality as an independent software company, we will continually provide quality-first IT services for our society as one of group companies of NTT DATA.
