Three locomotives were built by Hitachi in Mito, Ibaraki, in 1926, based on electric locomotives previously imported from overseas.[1] Initially designated Class 1170 under the original Japanese Government Railways (JGR) numbering scheme, the locomotives became Class ED15 from 1928.[1]

The locomotives were initially used on Tokaido Main Line freight services, and were later employed on the Chuo Main Line.[1]

The locomotives were withdrawn from service between 1959 and 1960.[1]


ED15 1 is preserved at the Hitachi Mito Factory in Hitachinaka, Ibaraki.[1]
