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 Inubō (
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,[9] and the remaining Inubō express services were discontinued and absorbed into the Shiosai services, giving seven return workings daily.[8]
From the start of the revised timetable on 10 December 2005, 255 series 9-car EMUs were introduced on Shiosai services.[10] From the same date, services were made entirely no-smoking.[10]
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.[11]
From the start of the 16 March 2024 timetable revision, E259 series 6-car EMUs used on Narita Express services are scheduled to also be used on Shiosai services for six return trips. Meanwhile, E257 series trains in 5-car formations will continue to be used for one return trip. As a result, 255 series sets will no longer operate on these services.[4]
