History
The Seto service commenced on 1 April 1950, as an "express" service operating between Tokyo and Uno in Okayama Prefecture.[3] From 11 November 1956, the name was changed to kanji, written as 瀬戸.[3] From 15 March 1972, the train was upgraded to become a "limited express" service.[3] In 1977, the 20 series sleeping cars were replaced by 24/25 series sleeping cars.[2]
