NTTs

NTTs is a plural form commonly used to refer to Nippon Telegraph and Telephone Corporation (NTT) and its group of companies, collectively known as the NTT Group. The group operates one of the largest telecommunications and information technology networks in Japan and maintains a substantial international presence through its subsidiaries.

Origin and structure: NTT began as the Nippon Telegraph and Telephone Public Corporation, a government-owned monopoly. It was privatized in 1985 and subsequently reorganized into a holding structure that separated local and long-distance networks and created specialized subsidiaries. The group now includes regional operating companies such as NTT East and NTT West, and major subsidiaries covering mobile communications (NTT DoCoMo), global networks and IT infrastructure (NTT Communications), system integration and IT services (NTT Data), and cybersecurity (NTT Security).

Services: The NTT Group offers fixed and mobile telephony, data communications, cloud and data center services, managed IT and security solutions, and network infrastructure. It operates extensive subsea cables, data centers, and enterprise services worldwide.

Global presence: While primarily a Japanese company, NTT maintains operations and facilities around the world, serving corporate and government clients, carriers, and consumers.

Significance: NTT is one of the largest telecommunications groups by revenue and influence, and its technology and networks underpin much of Japan’s communications infrastructure. The term NTTs may be used to reference the group as a whole or to refer to its individual companies collectively.
