ED75-0
This was the original type. Two prototypes, ED75 1 and 2, were delivered in 1963, built by Hitachi and Mitsubishi.[2] Following test running, a further 158 locomotives were built from 1964 by Hitachi, Mitsubishi, and Toshiba.[1] Locomotive numbers 50 to 100 were equipped for cold regions, and were fitted with icicle cutters above the driving cab windows.[1] As of 1 April 2016[update], no Class ED75-0 locomotives remained in service.[3]
ED75-300
11 Class ED75-300 locomotives were built from 1965 to 1968 by Hitachi and Mitsubishi for use in Kyushu, numbered ED75 301 to ED75 311. These locomotives used a 20 kV AC 60 Hz power supply.[2]

ED75-500
One Class ED75-500 locomotive, number ED75 501 was built experimentally for use on the recently electrified Hakodate Main Line between Otaru and Asahi in Hokkaido. No further locomotives in this sub-class were built, as Class ED76-500 locomotives were instead chosen for this route.[2]

ED75-700
91 Class ED75-700 locomotives were built from 1971 to 1976 by Hitachi, Mitsubishi, and Toshiba, for use on the Ou Main Line and Uetsu Main Line, numbered ED75 701 to ED75 791. These locomotives used a 20 kV AC 50 Hz power supply.[2] These locomotives differed from earlier examples in having PS103 cross-arm type pantographs.[1] 34 members of this subclass were converted to become Class ED79 locomotives in 1988 for use on services through the undersea Seikan Tunnel between Honshu and Hokkaido.[1][2]
As of 1 April 2016[update], five Class ED75-700 locomotives remained in service, operated by JR East, with three locomotives based at Sendai and two at Akita.[3]

ED75-1000
The ED75-1000 subclass were built from 1968 for use on express freight services. 25 locomotives were built between 1968 and 1970, followed by a second batch of 14 locomotives built from 1973 to 1976, bringing the total to 39.[2]
JR Freight started a programme of life-extension refurbishment of its Class ED75-1000 fleet from 1993, and refurbished locomotives were initially repainted in a new livery with the bottom half of the body sides finished in ivory.[4] The livery applied to refurbished locomotives was subsequently simplified to just adding a white stripe along the bottom of the body sides.[4]
From the start of the 17 March 2012 timetable revision, the remaining scheduled JR Freight workings using ED75 locomotives, operating in pairs, were completely replaced by JR Freight Class EH500 locomotives.[4]
