Question: Provide a comprehensive introduction to NTT, the company.
Answer:
NTT, Inc. (formerly known as Nippon Telegraph and Telephone Corporation) is one of the world’s largest telecommunications and information technology companies, headquartered in Tokyo, Japan.
History
NTT’s roots trace back to 1869 with the introduction of the telegraph in Japan. Modern operations began in 1952 when the Nippon Telegraph and Telephone Public Corporation was established as a government-owned entity to manage the country’s telecommunications infrastructure.
In 1985, it was privatized and became Nippon Telegraph and Telephone Corporation to introduce competition and liberalization in Japan’s telecom market. The company was a major global player in the late 1980s and 1990s, at times holding the position of the world’s largest company by market capitalization.
In a significant recent change, effective July 1, 2025, following amendments to the NTT Law, the company officially changed its name to NTT, Inc. (NTT株式会社), simplifying its branding while maintaining the iconic “NTT” abbreviation.
