In 1870, the Ministry of Communications launched a telegraph service between Tokyo City and Yokohama City.
On July 31, 1952, the Nippon Telegraph and Telephone Public Corporation Act was enacted. Based on this Act, Nippon Telegraph and Telephone Public Corporation ("Dendenkosha" for short), which would later become the core company of NTT, was set up on August 1, 1952 to promote widespread use of telephone services in Japan as a state-owned special corporation.

Telephone and communications services were expanded throughout Japan during the country's period of rapid economic growth and, in 1985, Nippon Telegraph and Telephone Public Corporation was privatized. To streamline its structure and expand its business domains, NTT founded a subsidiary for each line of business and established NTT.

NTT's sales (operating revenues) reached approximately 12.15 trillion yen in March 2022. (as of March 31, 2022).

We carried out the "Your Value Partner 2025" NTT Medium-Term Management Strategy based on the business of each existing group company. This included expanding our global cloud services, streamlining our high value-added network business, pursuing collaboration with a wide range of operators, and expanding our B2B2X business. As a result, we recorded our highest ever revenue and profits to date.

NTT Ltd.

NTT has registered approximately 17,000 patents to date. In response to market globalization and intensifying competition in technology development, we have effectively combined our and other companies' technologies, thereby efficiently and strategically spreading technologies as we grow our business.

Almost no other telecommunications company around the world has its own research and development division.

This is one more thing that sets NTT at a cut above the rest.
