Japanese National Railways in the context of "Division and privatization of Japanese National Railways"

The Japanese civil service employs over three million employees, with the Japan Self-Defense Forces, with 247,000 personnel, being the biggest branch. In the post-war period, this figure has been even higher, but the privatization of a large number of public corporations since the 1980s, including NTT, Japanese National Railways, and Japan Post, already reduced the number.

The vast majority of civil servants (2.74 million) are employed by local governments, while around 585,000 are national government civil servants. National civil servants are divided into "special" and "regular" service categories. Appointments in the special service category are governed by political or other factors and do not involve competitive examinations. This category includes cabinet ministers, heads of independent agencies, members of the Self-Defense Forces, Diet officials, and ambassadors.

The Tōkaidō Shinkansen (Japanese: 東海道新幹線; lit. 'East coast route, new main line') is a Japanese high-speed rail line that is part of the nationwide Shinkansen network. Along with the San'yō Shinkansen, it forms a continuous high-speed railway through the Taiheiyō Belt, also known as the Tokaido corridor. Opening in 1964, running between Tokyo and Shin-Ōsaka, it was the world's first high-speed rail line, and it remains one of the world's busiest. Since 1987, it has been operated by the Central Japan Railway Company (JR Central), prior to that by Japanese National Railways (JNR).

There are three types of services on the line: from fastest to slowest, they are the limited-stop Nozomi, the semi-fast Hikari, and the all-stop Kodama. Many Nozomi and Hikari trains continue onward to the San'yō Shinkansen, going as far as Fukuoka's Hakata Station. The different services operate at mostly the same speed.

NTT, Inc. (formerly known as Nippon Telegraph and Telephone Corporation) is a Japanese telecommunications holding company headquartered in Tokyo, Japan. Ranked 128th in Fortune Global 500, NTT is the sixth largest telecommunications company in the world in terms of revenue, as well as the 15th largest publicly traded company in Japan by market cap, and the 6th largest by revenue, as of November 2025. In 2025, the company was ranked 79th in the Forbes Global 2000. NTT was the world's largest company by market capitalization in the late 1980s, and remained among the world's top 10 largest companies by market capitalization until the burst of the Dot-com bubble in the early 2000s.

The company traces its origin to the national telegraph service established in 1868, which came under the purview of the Ministry of Communications in the 1880s as part of a postal, telegraph and telephone service. In 1952, the telegraph and telephone services were spun off as the government-owned Nippon Telegraph and Telephone Public Corporation. Under Prime Minister Yasuhiro Nakasone, the company was privatised in 1985 along with the Japan Tobacco and Salt Public Corporation and subsequently the Japanese National Railways two years later, adopting the previous name until July 2025. While NTT has been listed on the Tokyo Stock Exchange since 1987, the Japanese government still owns roughly one-third of NTT's shares, regulated by the NTT Law (Law Concerning Nippon Telegraph and Telephone Corporation, Etc.).

Yasuhiro Nakasone (中曽根 康弘, Nakasone Yasuhiro; 27 May 1918 – 29 November 2019) was a Japanese politician who served as Prime Minister of Japan from 1982 to 1987. His political term was best known for pushing through the privatization of state-owned companies and pursuing a hawkish and pro-United States foreign policy.

Born in Gunma Prefecture, Nakasone graduated from Tokyo Imperial University and served in the imperial navy during the Pacific War. After the war, he entered the National Diet in 1947 and rose through the ranks of the Liberal Democratic Party, serving as chief of the Defense Agency from 1970 to 1971 under Eisaku Satō, international trade and industry minister from 1972 to 1974 under Kakuei Tanaka, and administration minister from 1980 to 1982 under Zenkō Suzuki. As prime minister, he passed large defense budgets and controversially visited the Yasukuni Shrine. A conservative contemporary of U.S. president Ronald Reagan, Nakasone privatized the Japanese National Railways and telephone systems, and favored closer ties with the U.S., once calling Japan an "unsinkable aircraft carrier". After leaving office in 1987, he was implicated in the Recruit scandal, causing the influence of his LDP faction to wane before he retired from the Diet in 2004.

The Japan Railways Group, commonly known as the JR Group (Jeiāru Gurūpu) or simply JR, is a network of railway companies in Japan formed after the division and privatization of the government-owned Japanese National Railways (JNR) on April 1, 1987. The group comprises six regional passenger railway companies, one freight railway company, and two non-service entities. The JNR Settlement Corporation assumed much of the debt of the former JNR.

The companies of the JR Group operates a significant portion of Japan’s rail services, including intercity routes, commuter lines, and the Shinkansen high-speed rail network.

The Japanese Government Railways (JGR) was the national railway system directly operated by the Japanese Ministry of Railways (鉄道省, Tetsudō-shō; Japanese pronunciation: [te̞t͡sɨᵝdo̞ːɕo̞ː]) until 1949. It was a predecessor of Japanese National Railways and the later Japan Railways Group.
