These were built between 1964 and 1970. While not originally fitted with air-conditioning, most of the cars were fitted with air conditioning from 1975. The bogies of the trailer cars were changed from TR201 to TR212 for the cars built from 1968. Cars fitted with TR212 bogies feature disc brakes, because they needed to run on higher speeds on the Jōban and Hanwa Lines.KuMoHa 103: 1-155

This single 10-car unit was built in 1970. It was equipped with various air conditioning units and tested on the Yamanote Line in Tokyo. It was subsequently modified to become a standard air-conditioned set in 1978.

Some 101 series trailer cars were converted to the 103-0 series. The cars' bodies and bogies were 101 series originals as the conversions involved minimum modification. The last of these cars were withdrawn from service in 1999.SaHa 103: 751-780 (from SaHa 101)

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. The last set was retired in March 2006.
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. 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. Toilets were added to one end car of each set between June 2003 and October 2004.
Five three-car 103-3000 series sets (numbered 51 to 55) were formed in 1985 from former 72 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. The last set was withdrawn in October 2005.

One 4-car 103-3500 series set was formed in December 1995 from surplus 103-0 series cars to augment the fleet ahead of Hachikō Line electrification in March 1996. As with the 103-3000 series sets, passenger-operated door controls were fitted. The motor/trailer car configuration differed from that of the 103-3000 series sets. The set was withdrawn in March 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.
