Kintetsu Railway Co., Ltd.

The line that is now the Kashihara Line was completed in 1923 and the section of today's Osaka Line between Fuse and Yamato-Yagi in 1927, and the Shigi Line opened in 1930. The Kyoto Line began with Nara Electric Railway, a joint venture with Keihan Electric Railway that Kintetsu later absorbed. To reach Ise, Daiki founded Sangū Express Electric Railway ('Sankyū') on 28 September 1927; the line reached Ujiyamada in 1931, making day-trip pilgrimages from Osaka to the Ise Grand Shrine possible. Sankyū absorbed Ise Electric Railway in 1936, the year the affiliated Kansai Express Electric Railway was founded, and on 26 June 1938 that company opened its Kuwana–Nagoya section, completing the route from Osaka to Nagoya — the first private-railway service between the two cities.

Under the wartime Land Transport Business Coordination Act the group then merged with one neighbouring railway after another. Sankyū absorbed Kansai Express Electric Railway and the Yōrō Railway in 1940, and on 15 March 1941 Daiki itself merged with Sankyū to form Kansai Express Railway ('Kankyū'), with 437 km of routes across five prefectures. Kankyū absorbed Osaka Railway, owner of the present Minami Osaka Line, in February 1943, by which point the prototype of today's Kintetsu network was in place. Then on 1 June 1944, at the strong urging of the state, Kansai Express Railway and the long-established Nankai Railway merged to form Kinki Nippon Railway Co., Ltd. — with roughly 630 km of routes, the largest private railway company in Japan.

The forced union with Nankai did not last: on 1 June 1947 the former Nankai lines were transferred to Nankai Electric Railway (the renamed Kōyasan Electric Railway), returning the company — which kept the Kinki Nippon Railway name — to its Kansai-Express-era network. On 8 October 1947 it began running a charged limited express between Uehommachi and Nagoya — the first postwar revival of paid limited-express service in Japan and the origin of today's Kintetsu limited express network. In 1958 the 10000 series 'Vista Car', with double-deck cars, entered service. Because the Nagoya Line was narrow gauge while the Osaka and Yamada lines were standard gauge, through passengers had to change trains at Ise-Nakagawa — until the Ise Bay Typhoon of September 1959, when president Isamu Saeki had the planned regauging brought forward and carried out alongside the recovery works; conversion finished on 27 November, and through Osaka–Nagoya expresses with the new 10100 series 'Vista Car II' began that December. The network was then essentially completed by absorbing Nara Electric Railway (1963, today's Kyoto Line), Shigi-Ikoma Electric Railway (1964) and Mie Electric Railway (1965).

For the 1970 Osaka Expo, Kintetsu built the Toba Line and regauged the isolated Shima Line to bring the Ise-Shima resorts onto the network, and that March it opened the Namba Line, regaining its own access to Namba for the first time since the 1947 Nankai separation. Distinctive limited express trains followed: the 120 km/h 'Urban Liner' (1988), the 'Sakura Liner' (1990), the 'Ise-Shima Liner' (1994), the sightseeing 'Shimakaze' (2013) and the 'Hinotori', which entered Osaka Namba–Kintetsu Nagoya service in March 2020. Kintetsu trains also run through onto the Kyoto Municipal Subway Karasuma Line (from 1988), the Osaka Metro Chūō Line (all Keihanna Line trains) and, from 20 March 2009, the Hanshin Namba Line, linking the Nara area with Nishinomiya and Kobe. The company marked its centenary on 16 September 2010.

The English corporate name became Kintetsu Corporation in 2003, and in 2007 the Iga and Yōrō lines were handed to Iga Railway and Yōrō Railway to operate, Kintetsu retaining the infrastructure as a Type III railway business. On 1 April 2015 the group adopted a holding-company structure: the existing company was renamed Kintetsu Group Holdings, and its railway business passed to Kintetsu Split Preparatory Company, Ltd. (founded 30 April 2014), renamed Kintetsu Railway Co., Ltd. the same day; operation of the Utsube and Hachiōji lines passed to Yokkaichi Asunaro Railway. Kintetsu Railway today is a wholly owned subsidiary of Kintetsu Group Holdings and the core company of the Kintetsu Group, based in Uehommachi, Tennoji-ku, Osaka. Most of the network is 1,435 mm standard gauge electrified at 1,500 V DC; the Minami Osaka Line group remains 1,067 mm narrow gauge, and the Keihanna Line uses 750 V DC third rail. Its fleet of 1,905 electric multiple unit cars (April 2017) was Japan's second-largest among private railways after Tokyo Metro, with new 8A series commuter trains entering service in October 2024 and the 1A series in January 2026.
