Trains originally operated as 7+4-car formations on Super Hitachi limited express services between Ueno in Tokyo and Sendai via the Jōban Line, but were withdrawn from regular scheduled services from the start of the revised timetable on 16 March 2013. The majority of the fleet was subsequently modified to become the 651-1000 series, and re-employed on Akagi and Kusatsu limited express services from March 2014.
- 651-0 series: Original (nine 7-car and nine 4-car) AC/DC sets built from 1989
- 651-1000 series: 7-car and 4-car DC-only sets modified from 651-0 series between 2013 and 2014
- Izu Craile: Rebuilt 4-car resort trainset entering service in July 2016
As of 15 April 2019, a four-car 651-0 series set operates as a local service on a segment of Jōban Line between Iwaki and Tomioka, making 2 round trips a day. The 651-1000 series sets are used on Akagi, Swallow Akagi, and Kusatsu limited express services.
As of 1 October 2015, the fleet of original 651-0 series trainsets consists of three (out of the original nine) seven-car sets (K102, 103, 105) and five (out of the original nine) four-car sets (K201, 202, 204, 205, 205), based at Katsuta Depot.

The 651 series trains were introduced on new Super Hitachi limited services between Ueno and Sendai on 11 March 1989, and the trains received the 33rd Blue Ribbon Award presented annually in Japan since 1958 by the Japan Railfan Club.
From 2 December 2000, the Green car (car 4) was made entirely non-smoking, and the internal partitions were removed between December 2000 and January 2001. Three seats were added to the Green car in June 2004, increasing the seating capacity to 36. All cars became no-smoking from the start of the revised timetable on 18 March 2007. The refreshment vending machines were discontinued from 31 March 2008.
From the start of the revised timetable on 17 March 2012, six pairs of 651 series trains were removed from service and put into storage, replaced by new 10-car E657 series EMUs on Super Hitachi services. The entire fleet was replaced by the start of the revised timetable on 16 March 2013, but the sets were however retained for seasonal and additional workings.
From 1 October 2013, one 11-car 651 series formation was brought back into service for use on two Fresh Hitachi services daily while the E657 series fleet undergoes modification work to add LED seat reservation status indicators above each seat. This continued until March 2015.
651-1000 series conversions
Between late 2013 and early 2014, a number of 651 series sets were modified and renumbered 651-1000 series for use on Akagi and Kusatsu limited express services from the start of the revised timetable on 15 March 2014, replacing ageing 185 series EMUs. The modifications included disconnecting (but not removing) the original AC electrical equipment, replacing the original PS26 lozenge-type pantographs with the same PS33D single-arm pantographs used on E233 series suburban EMUs, and adding an orange bodyside stripe below the windows. No changes were made to the interiors.
Izu Craile resort train
Four-car set OM301 was rebuilt as a resort train set named Izu Craile (伊豆クレイル) between November 2015 and April 2016, and is scheduled to enter service on the Ito Line from 16 July 2016. The name is a portmanteau formed from "Cresciuto" (Italian for "mature"), "train", and the suffix "-ile". Car 1 has window-facing counter seats on the seaward side, car 2 has a bar counter and lounge, car 3 has semi-open compartments, and car 4 has conventional unidirectional 2+2-abreast seating.
