Due to increased demand, JR Freight began building more EF66s in 1989.
This batch of locomotives was classified EF66-100, with locomotive numbered EF66 101 to EF66 133.
The Class EF66-100 locomotives were fundamentally the same design as the EF66-0, but with slightly more modern external styling.
The driver's cabs are air-conditioned.
The Class EF66 100 locomotives were also built in two batches, EF66 101 to 108 and EF66 109 to EF133.
The second batch differed in having rectangular headlamps and tail lamps, while the first batch had round lamps.
