The 125 series is a single-car DC electric multiple unit (EMU) train type operated by West Japan Railway Company (JR-West) on local services in Japan since March 2003.
Design
The 125 series design is based on the 223-2000 series EMU design, with stainless bodies and steel front ends.
The cars have two pairs of sliding doors on each side, with provision for a third set of doors in the centre.
The second-batch cars (KuMoHa 125-9–12) delivered in 2003 differ from the earlier batch by having enlarged front-end skirts and darker grey tinted windows.

Operations
The 125 series is used on wanman driver-only operation services, primarily on the Obama Line and Kakogawa Line.
Up to five single cars can be operated together as a multiple car set.

A further six cars (KuMoHa 125-13–18) were built in September 2006 to coincide with the conversion of Tsuruga area services from 20 kV AC to 1,500 V DC electrification from 21 October 2006.
From the start of the revised timetable on 18 March 2023, 125 series trainsets began operation on the Maizuru Line.
