Part of a second, proposed "outer" second loop line, the Osaka Higashi Line, from Hanaten to Kyuhoji was opened on March 15, 2008, and the line from Shigino to Shin-Ōsaka is planned to open in 2020. This entry covers the original central loop line.
2x jr 225 series in temma station osaka loop line
Outline
This loop line consists of two tracks around the heart of metropolitan Osaka. Most trains consist of 8 carriages, with distinctive orange colour with white JR graphics on the front, rear and sides. The train schedule varies, but on average, two trains leave Tennōji Station and Ōsaka Station every seven minutes, in opposite directions.
Operation
On this line, JR West operates several types of trains. The line serves as a link between Ōsaka Station in northern Osaka (actually the Umeda district), and Tennōji in southern central Osaka. Some Limited Express trains linking north and south of the Osaka-Kobe-Kyoto area use the line as a bypass between the Tōkaidō Main Line in the north and the Hanwa Line in the south. Traffic is heavier in the eastern half, Osaka - Kyōbashi - Tennōji, than in the western half via Nishi-Kujō.
Direction
The completely loop shaped Osaka Loop Line is unable to use the 'up' and 'down' train direction convention commonly applied in Japanese railways, e.g. trains traveling to Tokyo are usually 'up' trains and vice versa. Instead, the words "outer circle" (or outer loop) (外回り, Soto mawari) and the "inner circle" (内回り, Uchi mawari) are used to refer to the direction. The outer is clockwise, the inner counterclockwise.
If rules, such as the registration of the line at Ministry of Land, Infrastructure and Transport apply, the inner loop is down.
Local
Local trains are operated all day. Some operate over the complete loop, while some serve the eastern half between Osaka and Tennōji via Kyōbashi.
Eight-car EMUs of 103 series and 201 series are used.
Sakurajima Line trains
Trains of the Sakurajima Line (JR Yumesaki Line) are now operated through to the loop line to/from Kyōbashi and Tennoji.
Eight-car 103 series and 201 series EMUs are used.
Rapids of Kansai Main Line
Through trains to the Kansai Main Line (Yamatoji Line) began operated in 1973. "Yamatoji Rapid" (大和路快速, Yamatoji Kaisoku) and "Regional Rapid" (区間快速, Kukan Kaisoku) trains originate at Tennōji on the loop, passing the loop as "inner" via Osaka, and after stopping at Tennōji after a complete circuit, exit the loop onto the Kansai Main Line and terminate at Kamo, Nara or Ōji. In the loop, Yamatoji Rapids pass some stations while Regional Rapids stop all.
For "Yamatoji Rapid", 6 or 8-car 221 series EMUs are used, while 8-car 103 series of light green livery and 6 or 8-car 221 series are for "Regional Rapid".
Rapids of Hanwa Line
Trains to the Hanwa Line, "Kansai Airport Rapid" (関空快速, Kankū Kaisoku) for Kansai Airport and Kishūji Rapid (紀州路快速, Kishūji Kaisoku) for Wakayama originate at either Tennoji or Kyobashi, and together with other types of rapid trains, operate on the inner loop via Osaka, pausing at Tennoji and then exiting from the loop. This pattern commenced in 1989, but increased significantly in 1994 on the opening of Kansai Airport.
8-car 223 series and 225 series EMUs in 4+4 formations are used for Kansai Airport and Kishūji rapids. 113 series 4-car units were used for rapids of Shin-Ōsaka - Kii-Tanabe in early morning and late night. They were withdrawn in 2010.
Limited express
Charged Limited Expresses such as Haruka for Kansai International Airport, and south bound Kuroshio on the Hanwa Line and Kisei Main Line (Kinokuni Line) heading for the scenic southern Wakayama Prefecture utilise the Osaka Loop Line to bypass the Tōkaidō Main Line and reach the Hanwa Line. On the loop, aside from Tennōji, limited numbers of trains stop only at Nishi-Kujō.
Between the Tōkaidō Main Line and the Osaka Loop Line, trains utilse the "Umeda freight line" which crosses immediately west of Ōsaka Station, not stopping at Osaka because no passenger facilities are installed on the freight line, until it merges the main line at Shin-Ōsaka. This route was introduced in 1989 on the completion of a bypass track from the Hanwa Line to platforms of the Kansai Main Line at Tennōji. Until then no through operations were possible from the Hanwa Line.
281 series EMUs are used for Haruka, 283 series EMUs, 287 series EMUs and 289 series EMUs for Kuroshio.
Freight trains
After the abandonment of the Naniwa freight terminal, freight trains on the line operate only between Fukushima and Nishikujō, from the "Umeda Freight Line" to Ajikawaguchi on the Sakurajima Line (JR Yumesaki Line).
Stations

Fares
A special discount rate is applied for travels within the Osaka Loop Line, the Sakurajima Line and the segment between JR Namba Station and Tennōji Station of the Kansai Main Line (collectively called the Osaka Loop Zone (大阪環状線内, Ōsaka Kanjōsen-nai)). The following table is the rate for adult single-ride tickets. (Note: Fractions of one kilometre are rounded up to the nearest full kilometre.)
For travel between a station within the zone and a station out of the zone or between two stations out of the zone, fares are calculated in accordance with a universal fare table and the discount rate as above is not applicable.
For the calculation of the fare for travel between two stations out of the zone that includes the segment between Ōsaka Station and Tennōji Station of the Osaka Loop Line, where two routes (10.7 km route via Temma and 11.0 km route via Fukushima) are practical, the shorter route is always used irrespective of the actual travel route.
History
The Osaka Loop Line consists of four segments, namely:
Jōtō Line
The Osaka to Tennōji via Kyōbashi section (the eastern half of Osaka Loop Line) was opened by the Osaka Railway (大阪鉄道, Osaka Tetsudō) (which also opened the present Minami Osaka Line network) to link it to the Japanese Government Railway (JGR) network in 1895. The line was opened in 2 stages: Tennōji - Tamatsukuri (2 mi. 28 chain, ca. 3.8 km) on 28 May; and Tamatsukuri - Umeda (4 mi. 29 chain, ca. 7.0 km) on 17 October.
Earlier, in 1889, the company opened its main line from Kashiwara - Tennōji - Minatomachi (湊町, present JR Namba) which includes a short section of the Osaka Loop Line, being Tennōji - Imamiya; Imamiya station itself, located between Tennōji and Minatomachi, was opened in 1890.
The Osaka Railway merged with the Kansai Railway (関西鉄道, Kansai Tetsudō, also read as Kansei or Kwansai) in 1900, creating a single entity for the line from Tennōji Station to JGR Ōsaka Station. The Kansai Railway was acquired by the national government in 1907 under the 1906 Railway Nationalization Act. In 1909 the line was named the "Jōtō Line" (城東線, Jōtō sen).
In 1930, distrances were changed to metric, thus the distance changed from 6.6 mi (10.6 km). to 10.7 km. Electrification of the Jōtō Line was commissioned in 1933.
Nishinari Line
The Osaka to Nishi-Kujō section (the northwestern quarter of the line) was built by the Nishinari Railway (西成鉄道, Nishinari Tetsudō) to provide rail access to the Osaka Port. In 1898, the company opened the Osaka - Ajikawaguchi line, which was leased to JGR in 1904. In 1906 the company was nationalized under the act of the same year. In 1909, the line was named the "Nishinari Line" (西成線, Nishinari sen) which included the present-day Sakurajima Line.
The Nishinari Line was electrified in 1941.
Kansai Main Line Freight Line
The Tennōji to Sakaigawa Signal Box (between Taishō and Bentenchō, closed in 2006 when the branch to the port closed) section (south-western portion of the loop) was constructed for freight traffic by the JGR to the port area in 1928, connecting to a freight branch line of the Kansai Main Line, Imamiya - Naniwa (浪速) - Osaka-minato (大阪港, apart from the present Ōsakakō Station on the Osaka Municipal Subway Chūō Line) with a distance of 5.2 mi. (ca. 8.4 km). In 1930 with the change to metric measurement, it became 8.2 km. The former Osaka-Minato and Osaka-Tōkō stations were closed in 1984.
Purpose-built loop line section
The completion of the Loop Line involved the construction of new railway tracks between Nishi-Kujō and Sakaigawa Signal Box by the Japanese National Railways at the time. This segment was inaugurated in 1961, leading to the establishment of the new Osaka Loop Line. This designation encompassed the entire Jōtō Line, the Osaka - Nishi-Kujō segment of the Nishinari Line (with the remaining part, Nishi-Kujō - Sakurajima, being renamed as the Sakurajima Line), and the newly constructed Nishi-Kujō - Taishō - Tennōji section.
In 1964, operation as a complete Loop Line commenced with the opening of elevated double tracks around Nishi-Kujō. Until then the operation had been undertaken in the shape of a mirrored "6", Sakurajima - Nishi-Kujō - Osaka - Kyōbashi - Tennōji - Nishi-Kujō. The Tennōji - Shin-Imamiya section was quadrupled in 1968, to separate operations from the Kansai Main Line.
