Broadly based on the 103 series commuter EMU, the 301 series was designed specifically for use on through-running services with the Eidan Tozai Line (present-day Tokyo Metro Tozai Line) in Tokyo, and was the first aluminium-bodied rolling stock introduced on Japanese National Railways (JNR).
When first delivered, the sets were finished with a clear acrylic paint, giving an unpainted appearance. The sets were subsequently painted in light grey with a yellow bodyside stripe. This was later changed to a light blue ("Blue No. 22") stripe to match the Tōzai Line line colour.
For cost reasons, only 56 vehicles were built, and subsequent rolling stock built for Tozai Line through-running services was conventional steel-bodied 103-1200 series stock.
Following reforming into 10-car sets, the fleet was formed as follows, with car 1 at the Nishi-Funabashi end and car 10 at the Mitaka end. Sets K1 and K2 included former KuHa 301 and KuMoHa 300 driving cars with driving cab equipment removed.

The 301 series were delivered in 1966 to Mitaka Depot in Tokyo, initially formed as eight 7-car sets. From 1981, the fleet was reformed into 10-car sets with the creation of SaHa 301 trailer cars converted from former MoHa 300 and MoHa 301 motored cars.
As of 1 April 2002, 50 vehicles (5 x 10-car sets) remained in service, but the fleet was subsequently replaced by new E231-800 series EMUs and withdrawn during 2003.
A special Sayonara 301 series train was run by JR East on 3 August 2003.
Driving car KuMoHa 300-4 of set K2 is stored at JR East's Omiya Works.
