The is an AC electric multiple unit (EMU) train type operated on local services by East Japan Railway Company (JR East), Aoimori Railway, and Iwate Galaxy Railway (IGR) in Japan. The design is derived from the 209 series commuter EMU, and was intended to replace locomotive-hauled trains formed of coaches in the north of Japan.[3]
89 701-0 series cars were delivered in 1993, formed as three-car sets (N1 to N13) and two-car sets (N14 to N38), all based at Akita Depot. Three two-car sets (N36 to N38) were later modified with some transverse seating, and from 2005, the entire fleet had the original PS104 scissors-type pantographs replaced with PS109 single-arm pantographs. Snowploughs were also added to the front ends at the same time.[4]
These sets are used on the Uetsu Main Line between and, on the Ōu Main Line between and, and on the Tsugaru Line between and . The sets with transverse seating are mainly used on the Ōu Main Line between Shinjō and Akita.[4]

Thirteen 701-100 series cars were delivered in 1994, formed as one 3-car set and five 2-car sets. All sets were initially based at Akita Depot, but four of the 2-car sets were subsequently transferred to Sendai. The Akita-based sets had the original PS104 scissors-type pantographs replaced with PS109 single-arm pantographs between 2007 and 2008. Snowploughs were also added to the front ends at the same time. The Sendai-based sets had the original PS104 scissors-type pantographs replaced with lower-profile PS105 lozenge-type pantographs in 2002 to allow operation through limited-clearance tunnels on the Senzan Line.[4] [5]
The Sendai-based sets are normally used on the Joban Line between and, and on the Tohoku Main Line between Iwanuma and Sendai. They are also available for use on Senzan Line services if required. The Akita-based sets are used interchangeably alongside the 701-0 series sets.[4]

92 701-1000 series cars were delivered between 1994 and 1995 to Morioka and Sendai depots, formed as 2- and 4-car units. As of 2010, 14 cars (seven 2-car sets), 30 cars (fifteen 2-car sets) are based at Morioka, and 36 cars (four 4-car sets and ten 2-car sets) are based at Sendai. Eight of the original 2-car sets were transferred to the Iwate Galaxy Railway Line, becoming IGR 7000-0 series (see below), and one 2-car set was transferred to the Aoimori Railway, becoming Aoimori 700-0 series (see below). On 28 October 1999, one Aomori-based 2-car set (KuMoHa 701-1033 + KuHa 700-1033) was damaged by storm surge at Aomori Station. New bodies were manufactured for this set in 2000, and it was renumbered KuMoHa 701-1508 + KuHa 700-1508 and reallocated to Sendai depot.[4]
A further seven 701-1000 series two-car sets were transferred to the Aoimori Railway during 2010, becoming Aoimori 700-0 series.
The Sendai-based sets are used on the Tohoku Main Line between and, including the branch line to, and on the Senzan Line. The Morioka-based sets are used on the Tohoku Main Line between and, and on the Iwate Galaxy Railway Line between Morioka and . The Aomori-based sets are used on the Tohoku Main Line between and .[4]

Eighteen two-car sets (numbered F2-501 to F2-518) were delivered to Sendai depot between 1998 and 2001, including set F2-508, which was rebuilt from an earlier damaged 701-1000 series unit. Sets from F2-509 onward were fitted with wheelchair spaces and ATS-Ps from new. They are used interchangeably with Sendai 701-1000 series sets.[4]
