NTT Group's Roots

continued to develop a range of solutions as a partner that enables society and industry to move ahead.

It was some 70 years ago that the telephone and telegraph services provided by the Ministry of Communications and Ministry of Telecommunications were handed over to Nippon Telegraph and Telephone Public Corporation. With economic growth booming following the country's post-war recovery, the company began exploring a range of avenues to meet growing public demand for telephone services that connect in an instant.
After subsequently undergoing a name-change to NTT, the company expanded its businesses including the regional communications, long-distance and international communications, mobile communications, and global data communications sectors, based on its roots that aim to respond to the needs of customers and challenges faced by industry and society.
Focused on creating a better future for Japan and the world... Never losing sight of the goal as "Your Value Partner."
