The Osaka Higashi Line (おおさか東線, Ōsaka-Higashi-sen; lit.'Osaka East Line') is a railway line in Osaka, Japan, operated by the West Japan Railway Company (JR West). The line connects Ōsaka Station in northern Osaka with Kyūhōji Station in Yao, forming an arc around the northern and eastern suburbs of the city. Before being named on August 23, 2007, the line was constructed with the tentative name "Osaka Outer Loop Line" (大阪外環状線, Ōsaka-soto-kanjōsen).
The line is constructed and owned by Osaka Soto-Kanjo Railway Co., Ltd. (大阪外環状鉄道株式会社, Ōsaka Sotokanjō Tetsudō Kabushiki Kaisha) as a Category 3 railway business under the Railway Business Act of Japan. JR West and JR Freight run trains as Category 2 operators.[citation needed] The Kita-Umeda extension opened on March 18, 2023, replacing the above-ground Umeda Freight Line.
History
Conceived in the 1950s during Japan's explosive postwar economic growth, it was planned as a grand "outer loop" of the city, using existing freight lines to link Amagasaki with Shin-Ōsaka, Suita, Awaji, Hanaten, Kami, Uriwari and Sugimotochō, with a newly constructed segment into Osaka's (then primarily industrial) Nankō Port Town. However, with JNR's financial situation deteriorating catastrophically (culminating in its privatization) and continuing issues surrounding land acquisition and squatting by local residents on railway property, the plan was cut back to Shin-Osaka and Kami, terminating at Kyūhōji in the south.[citation needed] (The Hanwa Freight Line, which would have carried the southern segment from Kami to Sugimotochō, was officially abandoned by JR Freight in 2009.) The line connects Shin-Osaka Station in northern Osaka with Kyūhōji Station in Yao, forming an arc around the northern and eastern suburbs of the city.
The southern part opened on March 15, 2008.[1][clarification needed] Due to problems with the illegal occupation of a site, construction of the northern part was delayed.[2] Construction of the northern segment started in 2011, and the section between Shin-Ōsaka and Hanaten opened on March 16, 2019.[3][4]
Incorporated into the second phase of the Osaka Higashi Line project is the construction of underground platforms at Osaka Station (known as Umekita).[5] The project provides the basis for the future Naniwasuji Line while also providing a small shortcut on current services on the Haruka and Kuroshio limited express trains.
In February 2023, track switching work took place between the 11th and 13th of that month.[6] The underground platforms began operation later in the year on March 18.[7]
