Kintetsu Railway Co., Ltd. (近畿日本鉄道株式会社, Kinki-nippon Tetsudō Kabushiki-gaisha), referred to as Kintetsu (近鉄) and officially Kinki-Nippon Railway, is a Japanese passenger railway company, managing infrastructure and operating passenger train service. Its railway system is the largest in Japan, excluding Japan Railways Group. The railway network connects Osaka, Nara, Kyoto, Nagoya, Tsu, Ise, and Yoshino. Kintetsu Railway Co., Ltd. is a wholly owned subsidiary of Kintetsu Group Holdings Co., Ltd.

The Shinkansen (Japanese: 新幹線; [ɕiŋkaꜜɰ̃seɴ] , lit. 'new trunk line'), colloquially known in English as the bullet train, is a network of high-speed railway lines in Japan. It was initially built to connect distant Japanese regions with Tokyo, the capital, to aid economic growth and development. Beyond long-distance travel, some sections around the largest metropolitan areas are used as a commuter rail network. It is owned by the Japan Railway Construction, Transport and Technology Agency and operated by five Japan Railways Group companies.

Starting with the Tokaido Shinkansen (515.4 km; 320.3 mi) in 1964, the network has expanded to consist of 2,951.3 km (1,833.9 mi) of lines with maximum speeds of 260–320 km/h (160–200 mph), 283.5 km (176.2 mi) of Mini-shinkansen lines with a maximum speed of 130 km/h (80 mph), and 10.3 km (6.4 mi) of spur lines with Shinkansen services. The network links most major cities on the islands of Honshu and Kyushu, and connects to Hakodate on the northern island of Hokkaido. An extension to Sapporo is under construction and was initially scheduled to open by fiscal year 2030, but in December 2024, it was delayed until the end of FY2038. The maximum operating speed is 320 km/h (200 mph) (on a 387.5 km (241 mi) section of the Tōhoku Shinkansen). Test runs have reached 443 km/h (275 mph) for conventional rail in 1996, and up to a world record 603 km/h (375 mph) for SCMaglev trains in April 2015.

The East Japan Railway Company is a major passenger railway company in Japan and the largest of the seven Japan Railways Group companies. The company name is officially abbreviated as JR East in English, and as JR Higashi-Nihon in Japanese. The company's headquarters are in Yoyogi, Shibuya, Tokyo, next to Shinjuku Station. It is listed in the Tokyo Stock Exchange (it formerly had secondary listings in the Nagoya and Osaka stock exchanges), is a constituent of the TOPIX Large70 index, and is one of three Japan Railways Group constituents of the Nikkei 225 index, the others being JR Central and JR West

The West Japan Railway Company, also referred to as JR West (JR西日本, Jeiāru Nishi-Nihon; lit. 'JR West Japan'), is one of the Japan Railways Group (JR Group) companies and operates in western Honshu. It has its headquarters in Kita-ku, Osaka. It is listed in the Tokyo Stock Exchange, is a constituent of the TOPIX Large70 index, and is also one of only three Japan Railways Group constituents of the Nikkei 225 index: the others are JR East and JR Central. It was also listed in the Nagoya and Fukuoka stock exchanges until late 2020.

The Hokkaido Railway Company (北海道旅客鉄道株式会社, Hokkaidō Ryokaku Tetsudō kabushiki gaisha) is one of the constituent companies of the Japan Railways Group (JR Group), and is often referred to by its official abbreviation: JR Hokkaido (JR北海道, Jeiāru Hokkaidō). It operates intercity and local rail services in Hokkaido, Japan. The company introduced Kitaca, a smart card ticketing system, in autumn 2008.

At the time of its privatization in 1987, JR Hokkaido operated 21 railway lines totalling 3,176.6 kilometres (1,973.8 mi) of narrow-gauge (1,067 mm (3 ft 6 in)) track, as well as a ferry service to Aomori. Since then, that figure has dwindled to just below 2,500 kilometres (1,600 mi), as unprofitable lines have been shut down or spun off (in the case of the Hokkaidō Chihoku Kōgen Railway). The ferry service has also been replaced by the 53.85-km long dual-gauge Seikan Tunnel for railways.

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.

The division and privatization of Japanese National Railways (国鉄分割民営化, Kokutetsu bunkatsu min'eika) was a major administrative reform implemented by the Zenkō Suzuki Cabinet and Nakasone Cabinet. Under this reform, the Japanese National Railways (JNR) was divided into six regional passenger railway companies and one freight railway company, collectively known as the Japan Railways Group (JR), and these entities were privatized. The new companies officially began operations on April 1, 1987, bringing the 115-year history of JNR to a close.

In the transition to the new companies, approximately 94,000 employees—about one in three—were deemed surplus personnel. Around 70,000 of them left JNR through a voluntary retirement program with enhanced severance payments. Even after the liquidation was completed, about 16.7 trillion yen in debt remained, which was ultimately covered by the public.
