The 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.[1]
The 125 series design is based on the 223-2000 series EMU design, with stainless bodies and steel front ends.[1]
The cars have two pairs of sliding doors on each side, with provision for a third set of doors in the centre.[1]
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.[1]
The 125 series is used on wanman driver-only operation services, primarily on the Obama Line and Kakogawa Line.[1]
Up to five single cars can be operated together as a multiple car set.[1]

Cars KuMoHa 125-7/8/11/12 are equipped with a second de-icing pantograph.[2]
Passenger accommodation consists of longitudinal bench seating at the ends, and 2+2 abreast transverse reversible seating in the centre of the cars.[1] The first two batches of cars (KuMoHa 125-1–12) were delivered with 1+2 abreast seating, but this was increased to 2+2 seating during 2003 and 2004.[2]
The first eight cars (KuMoHa 125-1–8) were built by Kawasaki Heavy Industries in December 2002 for entry into service from 15 March 2003 on the then-newly electrified 84.3km (52.4miles) Obama Line between and .[2] These sets were initially allocated to Fukuchiyama Depot, but were subsequently transferred to Tsuruga Depot.[1]
Four more cars (KuMoHa 125-9–12) were built in September 2004 for entry into service from 19 December 2004 on the newly electrified 48.5km (30.1miles) Kakogawa Line between and .[2]
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.[1] [2]
From the start of the revised timetable on 18 March 2023, 125 series trainsets began operation on the Maizuru Line.[3]
