The Kuroshio (くろしお) is a limited express train service in Japan connecting Kyoto, Shin-Osaka, Tennōji, Wakayama, Kii-Tanabe, Shirahama, and Shingu via the Tokaido Main Line (JR Kyoto Line), Osaka Loop Line, Hanwa Line, and Kisei Line (Kinokuni Line), operated by West Japan Railway Company (JR West). This article also covers the derivative limited express trains, "Super Kuroshio (スーパーくろしお)" and "Ocean Arrow (オーシャンアロー)", the names of which were discontinued from start of the revised timetable on 17 March 2012.
Stations in brackets () are stations where not all trains stop at.
Previously, train services went directly between the Loop Line and Shin-Osaka via the Umeda Freight Line, resulting in no trains going to Osaka Station. This changed on 13 February 2023 when trains started to route through new underground platforms at Osaka Station.[1] The new platforms were opened on 18 March 2023.
New 287 series EMUs were introduced on Kuroshio services from start of the revised timetable on 17 March 2012. From the same date, the Super Kuroshio and Ocean Arrow service names were discontinued, with services integrated with Kuroshio services.[3]
New 289 series EMUs converted from former dual-voltage 683 series trainsets were introduced on Kuroshio services from 31 October 2015, replacing the last remaining JNR-era 381 series trains.[4] The 289 series fleet consists of five six-car sets and three three-car sets (39 vehicles in total).[2]
