Built jointly by Hitachi, Kawasaki Heavy Industries, and Kinki Sharyo, the design was developed from the earlier 211 series, with the first five trains introduced from July 1989 to replace older 113 and 115 series EMUs. Eight more sets were introduced from the start of the new timetable in March 1990, and a further two sets were introduced in March 1991.
As of 1 October 2015[update], the fleet consists of 15 four-car sets (G1 to G15), all based at Ogaki Depot. The trainsets are formed as shown below with two motored cars and two non-powered trailer cars.
