The Aichi Loop Line (愛知環状鉄道線, Aichi Kanjō Tetsudō-sen; "Aichi Loop Railway Line") is a Japanese railway line connecting Okazaki Station in Okazaki and Kōzōji Station in Kasugai. It is the sole line operated by Aichi Loop Railway (愛知環状鉄道, Aichi Kanjō Tetsudō). The line and operating company are both abbreviated as Aikan (愛環). Despite its name, the line is a not a true loop; however, it can be said to form a loop with the JR Tokaido Line and Chuo Line serving as other portions of the circle.

The Aichi Loop Railway is a third-sector company, with shares held by public sector such as Aichi Prefecture, the city of Toyota, and also by private companies. Unlike typical third-sector lines in Japan, the Aichi Loop Line makes a profit, as it functions as commuter rail for nearby Toyota Motor factories and offices.

History

The line's construction was proposed by the amended Railway Construction Act on 30 March 1927. The line was described as a railway line starting from Okazaki, Aichi Prefecture, passing through Koromo and terminating at Tajimi, Gifu Prefecture.[2] The Ministry of Railways considered establishing bus routes before constructing railway lines for some of the proposed lines that were considered hard to sustain. Out of the seven candidates, this route was selected as the first bus route of this plan. The bus route opened as the Okata Line (岡多線) on 20 December 1930 with seven buses and ten trucks. This bus line has since been abolished in 2002.[3]

Construction of the Okata Line by the Japan Railway Construction Public Corporation[4] commenced on 13 August 1965. Freight operations on the line between Okazaki and Kitano-Masuzuka began on 1 October 1970.[5]

The first section of the line between Okazaki and Kitano-Masuzuka opened for passengers in 1970, as a railway line of the Japanese National Railways (JNR). The section between Kitano-Masuzuka and Shin-Toyota was extended and the whole line started a passenger service in 1976. Another part of the line, between Setoshi and Kōzōji, was originally part of a freight line planned as the JNR Seto Line. The line did not do well financially under JNR ownership, and it was later designated for closure.[6]

The newly founded third-sector Aichi Loop Line Company took over the line, now renamed to the Aichi Loop Line, from Central Japan Railway Company (JR Central), with services starting on 31 January 1988. Beginning on 1 March 2005, through service began with the JR Chuo Main Line to Nagoya Station, initially to carry visitors to the site of Expo 2005.[6][5]

The line became compatible with TOICA, a contactless smart card, on 2 March 2019.[7]

Network and operations

Three to five trains run in each direction per hour, while one or two train run in each direction instead during the first and last hours of service. Trains in two-car or four-car formations are operated. Some services operate with reduced cars, or are not operated at all during weekends.[8]

The line does not form a loop line by itself, although it connects to the Chūō Main Line or the Tōkaidō Main Line on each side of the terminus. Toyota factories and offices, along with various schools, are located alongside the line,[9] and the line transports commuters to those locations, allowing it to turn a profit unlike other formerly JNR-owned third-sector companies.[10]

Infrastructure
