Exterior
The car bodies are constructed of stainless steel and are based on JR Central's 313 series electric multiple unit design. The beading on the lower bodyside was discontinued on the second-batch units, giving flush body sides. The second-batch units have cushions on the front-end skirts to prevent damage from collisions with deer.

Interior
Seating in the first-batch units (P1 to P5) consists of transverse flip-over seats arranged 2+2 abreast, with interiors based on the 313-1300 series EMU design. The second-batch sets (P101 onward) have longitudinal seating.

History
The first two sets, P1 and P2, were delivered from the Nippon Sharyo factory in Toyokawa to Nagoya on 10 November 2010. The remaining three sets, P3 to P5, were delivered on 23 February 2011.

The type entered service on the Taketoyo Line from 1 March 2011.

A second batch of KiHa 25 series trains is on order by JR Central, with a total of 52 new vehicles scheduled to be introduced between fiscal 2014 and 2015 on the Takayama Main Line, Taita Line, Kisei Main Line, and Sangu Line, at a cost of approximately 12 billion yen, replacing all remaining former JNR-era DMUs, including KiHa 40, KiHa 47, and KiHa 48 types. The new batch of trains will include LED interior lighting.
