Our Heritage

Since 1967, NTT DATA has played an instrumental role in establishing and advancing Japanese IT infrastructure, in particular large-scale and mission critical IT systems. Originally Data Communication Headquarter of Nippon Telegraph and Telephone Public Corporation, its heritage contributed to social benefits with a quality-first mindset. Having spun-off from NTT in 1988 and going public in 1995, the company maintained a hybrid culture of long-term commitment and challenge to innovation in order to contribute to the progression of business and society.

Today we build on this proven track record of innovation by providing novel IT solutions to customers in over 35 countries, all under the NTT DATA brand. We foster long-term collaboration that results in greater quality of life for people, communities and societies around the world.
