History

The ''Shiosai'' service was introduced from 10 March 1975 following the completion of electrification of the Sōbu Main Line in October 1974, using 9-car 183 series EMUs, replacing five of the seven daily diesel-powered express services that operated between / and .

From the start of the November 1982 timetable revision, further 183 series EMUs were drafted in, displaced from '' Toki'' limited express services following the opening of the Joetsu Shinkansen, and the remaining ''Inubō'' express services were discontinued and absorbed into the ''Shiosai'' services, giving seven return workings daily.

From the start of the revised timetable on 10 December 2005, 255 series 9-car EMUs were introduced on ''Shiosai'' services. From the same date, services were made entirely no-smoking.

From the start of the 14 March 2015 timetable revision, all ''Shiosai'' services started and terminated at Tokyo Station, with no services operating from Shinjuku.
