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 Inubō (犬吠) express services that operated between Shinjuku/Ryōgoku and Chōshi.[6]
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,[7] and the remaining Inubō express services were discontinued and absorbed into the Shiosai services, giving seven return workings daily.[6]
From the start of the revised timetable on 10 December 2005, 255 series 9-car EMUs were introduced on Shiosai services.[3] From the same date, services were made entirely no-smoking.[3]
Future developments
From the start of the 14 March 2015 timetable revision, all Shiosai services will start and terminate at Tokyo Station, with no services operating from Shinjuku.[8]
