A total of 19 cars have been delivered, formed as seven single-car KiHa 122 series units and six two-car KiHa 127 series units.[2] Test-running commenced in late September 2008,[4] with the units entering revenue-earning service from the start of the revised timetable on 14 March 2009.[5]

The body design features improved crash resistance, based on the 223 series electric multiple unit design. The cars use environmentally-friendly diesel engines with reduced NOx and particulate emissions.[6]
Externally, the units are finished in unpainted metal with thin yellow and red waistline stripes.[4]
Internally, the cars feature flip-over reversible seating arranged 2+1 abreast. Toilets in both types of train are wheelchair-accessible, and the step between the passenger compartment and station platform has been eliminated.[6]
The KiHa 122 single-car units and KiHa 127 two-car units are formed as follows.[7]
The KiHa 122 series uses a diesel engine with a small lithium-ion battery (18 kWh) that is used to power auxiliary machines in the train.[8]
