The first 1800 series trains entered service on 20 September 1969 on new Ryōmō express services from Asakusa in Tokyo to Akagi in Gunma Prefecture. 18 8-car sets were built between 1969 and 1973. An additional set, 1819, was built in 1987 as a 6-car set to provide increased capacity.
All cars were made no-smoking from 18 March 1995.
With the appearance of the new 250 series EMU, the 1800 series sets were removed from regular Ryōmō services from 1 April 1998. The remaining set, 1819, was subsequently used for charter trains and seasonal extra services.
From 1990, two 1800 series sets were modified to become 6-car 300 series sets, and from 1991, three more sets were modified to become 4-car 350 series sets. These entered service from 21 July 1991, replacing 6050 series on express services on the Nikkō Line.
Three sets (1811–1813) were kept in storage next to Tatebayashi Station from April 1998 following their withdrawal from Ryomo services. These were subsequently shortened to 4-car sets and modified for use on commuter services on the Sano Line and Koizumi Line from 23 April 2001, allowing ageing 5000 series EMUs to be withdrawn. Conversion involved arranging the seats in fixed 4-seat facing bays, removal of the vestibule partitions, and repainting in the Tobu commuter stock colour scheme of white with blue bodyline stripes. These sets were finally withdrawn in early 2007.
