The 103-0 series trains were built between 1963 and 1981. Built for JNR as an "upgraded" version of the 101 series, the 103 series has been widely used around Japan and has been manufactured in a multitude of different body styles and configurations.

Based on the earlier 101 series, the 103 series has been used on various commuter services since 1963. In fact, some 103 series cars were actually converted from 101 series cars. The 103 series was the main rolling stock used on urban commuter services for a time.

Some sets have been used for at least 50 years, and their age is starting to show; as such, their use on various lines is diminishing and they are being replaced by newer trains. For instance, the 103 series are being replaced by the newer 323 series on the Osaka Loop Line where they famously operate.

The sets have been manufactured in a multitude of different body styles, with additional body styles being created over the years. Older sets had body styles similar to the one used on the 101 series.

160 103-1000 series cars (16 10-car sets) were built in 1970 and 1971 for use on Jōban Line-Chiyoda Line inter-running services, which commenced in 1971. Originally painted in grey with a sea green stripe, they were subsequently displaced by new 203 series trains. Some sets were later converted to become 105 series, and the rest of the fleet was reallocated to Jōban Line services from Ueno.[7] In 1989, one Joban Line set was reallocated to the Chūō-Sōbu Line-Tōzai Line inter-running services. This set was repainted in grey with light-blue stripe, which was the same livery as the 103-1200 series. The last set was retired in March 2004.

Similar to the 103-1000 series, these were 7-car sets built by Nippon Sharyo and Tokyu Car Corporation for use on Chūō-Sōbu Line-Tōzai Line inter-running services alongside the aluminium-bodied 301 series. 5 sets (35 cars) were built between 1970 and 1978. They were initially painted in grey with a yellow stripe, but this was changed to a light blue stripe from 1989 to avoid confusion with the similarly coloured 205 series trains introduced on Chūō-Sōbu Line services.[7] The last set was retired in July 2003.

Nine 103-1500 series 6-car sets were built between 1982 and 1983 by Kawasaki Heavy Industries and Hitachi for use on inter-running services between the Chikuhi Line and the Fukuoka City Subway Kūkō Line in Kyushu. In 1989, four sets were reformed as eight 3-car sets (numbered E11 to E18) by rebuilding MoHa 103 and MoHa 102 cars as KuMoHa 103 and KuMoHa 102 cars respectively. They were initially painted in light blue with a white stripe, but were repainted into a grey and red livery from 1995. The 3-car sets were modified for driver-only operation between December 1999 and March 2001.[8] Toilets were added to one end car of each set between June 2003 and October 2004.[9]

Five three-car 103-3000 series sets (numbered 51 to 55) were formed in 1985 from former 72-970 series EMU cars for use on the Kawagoe Line following electrification in September 1985. Five MoHa 72970 cars were also converted to SaHa 103-3000 cars to augment Ome Line trains. These cars were fitted with passenger-operated door controls. The five Kawagoe Line sets were lengthened to four cars between October 1995 and March 1996 ahead of Hachiko Line electrification in March 1996.[7][10] The last set was withdrawn in October 2005.

One internal crew training set, formed as KuMoHa 103-100 + MoHa 102-224, was used for internal crew training at the JR East Crew Training Center at Higashi-Omiya Depot. The set had different cab end designs, as MoHa 102-224 used the cab of former ATC equipped KuHa 103-332, sets. It was withdrawn in 2009 following the delivery of a new 209 series-based training set in 2008.
