The Izumo (出雲) was a limited express overnight sleeping car train service in Japan operated by Japanese National Railways (JNR) and later by West Japan Railway Company (JR West), which ran from Tokyo to Izumoshi and Hamada in Shimane Prefecture until March 2006.

[1][2] In its latter years, the Izumo service was operated using JR East 24/25 series sleeping cars based at Oku Depot in Tokyo.

[4] From 19 November 1956, this was upgraded to become an "express" service (written in kanji as 出雲) operating between Tokyo and Hamada.

[5] The remaining pair of services followed the original route, travelling over the Sanin Main Line west of Kyoto, via Fukuchiyama.

[5] The last remaining Izumo services were withdrawn from the start of the revised timetable on 18 March 2006.
