Question: Give a comprehensive introduction to the history of NTT, the Japanese corporation.

Answer:

NTT (currently known as NTT, Inc.) is Japan’s largest telecommunications company and one of the world’s leading ICT (Information and Communications Technology) groups. Its history spans over 150 years, evolving from early telegraph services in the Meiji era to a modern global technology conglomerate.

Early Beginnings (1868–1952)

The roots of NTT trace back to the early introduction of telecommunications in Japan:

1868–1870: Telegraph services began in Japan shortly after the Meiji Restoration. The first telegraph line connected Tokyo and Yokohama in 1870 under the Ministry of Communications.
1890: The first telephone exchange service started in Tokyo and Yokohama.
Pre-WWII and wartime periods saw gradual expansion of telephone networks, but growth was limited and heavily disrupted during World War II (subscriber numbers dropped sharply).
Post-WWII reconstruction: Telecommunications remained under government control through the Ministry of Communications and later the Ministry of Telecommunications.

Nippon Telegraph and Telephone Public Corporation (1952–1985)

August 1, 1952: The Nippon Telegraph and Telephone Public Corporation (commonly called “Dendenkosha”) was established as a government-owned special public corporation. It took over all domestic telephone and telegraph services from the ministries.
The primary mission was rapid nationwide expansion of telephone infrastructure during Japan’s high-economic-growth period.
Key achievements:
- Telephone subscribers grew dramatically: ~1.5 million in 1953 → ~20 million by 1972.
- 1977: Telephone service became available nationwide, marking a major milestone in universal access.
The corporation also invested heavily in R&D through its Electrical Communication Laboratory (predecessor of today’s NTT R&D).
It played a crucial role in Japan’s rise in electronics, semiconductors, and telecommunications equipment manufacturing.
In the late 1970s, NTT announced visionary concepts such as the INS (Information Network System) in 1979, an early blueprint for an advanced digital network.

Privatization and the Birth of Modern NTT (1985–1999)

April 1, 1985: Under Prime Minister Yasuhiro Nakasone’s reforms (similar to those for Japan Tobacco and Japanese National Railways), the public corporation was privatized and became Nippon Telegraph and Telephone Corporation (still commonly abbreviated as NTT).
Goals of privatization: Increase efficiency, introduce competition in telecommunications, and reduce government monopoly.
1987: NTT shares were listed on the Tokyo Stock Exchange (and later on other exchanges). The IPO was massive — NTT became the world’s most valuable company by market capitalization in the late 1980s (peak during the Japanese asset bubble).
During the late 1980s and 1990s, NTT was frequently the world’s largest company by market cap.
Key subsidiaries were created:
- 1988: NTT DATA Corporation (IT services and system integration)
- 1992: NTT Mobile Communications Network (later NTT DOCOMO — pioneered mobile internet with i-mode in 1999)

Restructuring and Holding Company Structure (1999–2025)

1999: Major reorganization under telecommunications reform laws.
- NTT became a pure holding company.
- Main operating companies:
  - NTT East and NTT West (regional fixed-line telephone services)
  - NTT Communications (long-distance, international, and enterprise services)
  - NTT DOCOMO (mobile — later fully integrated)
  - NTT DATA (IT services)
This structure allowed greater competition while maintaining universal service obligations.
The group expanded globally, especially in data centers, cloud services, managed services, and submarine cables.

Recent Era — Global Tech Company and Name Change (2020s)

NTT Group has transformed into a comprehensive ICT provider with strong focus on:
- IOWN (Innovative Optical and Wireless Network) — next-generation all-photonics network concept
- AI, quantum computing research, 6G, sustainable technologies
July 1, 2025: The official corporate name changed from Nippon Telegraph and Telephone Corporation to NTT, Inc. to better reflect its global technology identity (while keeping the iconic “NTT” brand and “dynamic loop” logo).
As of early 2026:
- One of the world’s largest telecom companies by revenue (typically ranked in the global top 10)
- Major presence in Fortune Global 500 and Forbes Global 2000
- ~330,000–340,000 employees worldwide
- Operates through numerous subsidiaries in nearly 100 countries

Summary Timeline

1870 — First telegraph service (Tokyo–Yokohama)
1952 — Nippon Telegraph and Telephone Public Corporation established
1977 — Nationwide telephone service achieved
1985 — Privatized as Nippon Telegraph and Telephone Corporation
1987 — Stock market listing
1999 — Became holding company with regional/long-distance/mobile spin-offs
2025 — Renamed NTT, Inc.

From a government telegraph office to a global leader in optical networks, AI, and sustainable ICT, NTT’s history closely mirrors Japan’s own modernization, postwar recovery, economic miracle, and shift toward a digital, knowledge-based economy.
