History
Two 300 series six-car sets were built in 1990 from former 1800 series express EMUs displaced by the arrival of new 200 series EMUs. Three 350 series four-car sets were similarly rebuilt in 1991, with the trains entering service from the start of the revised timetable on 21 July 1991. The 300 series six-car sets were withdrawn on 20 April 2017, following the introduction of the Tobu 500 series. On 6 March 2022, the 350 series four-car sets were also withdrawn from service, alongside the discontinuation of Kirifuri limited express services.
