Established in 1988, NTT DATA was spun off from Data communications business headquarters of NTT (Nippon Telegraph and Telephone). It is also the industry's largest IT service provider with customers across a wide range of industries, mainly in the field of public and social infrastructure, as well as finance, and sales has been increasing for the 30th consecutive year since its establishment. Since around 2005, the company has been focusing on expanding global coverage and establishing the brand as its main business objectives.
