NTT is an acronym for Nippon Telegraph and Telephone Corporation.
NTT's business consists of integrated ICT (NTT DOCOMO, NTT Communications, and NTT COMWARE etc.), regional communications (NTT EAST and WEST etc.), global solutions (NTT DATA etc.), real estate (NTT Urban Solutions), energy (NTT Anode Energy) and others.
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 13.13 trillion yen in March 2023. (as of March 31, 2023).
NTT Group's fiscal 2022 financial results increased sales and profits which is based on the business of existing group companies, and due to the effect of increased sales in the global solutions business. Operating income profits hit a record high.
Approximately 330,000 employees work at NTT. NTT now has over 900 related companies making it a global enterprise that delivers ICT services across the world.
NTT has registered approximately 19,000 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.
