The line uses a fleet of LE-Car II series diesel railcars classified "Isumi Class 200".

In December 2010, former JR West KiHa 52 diesel car KiHa 52-125, formerly used on the Ōito Line was purchased by the Isumi Railway. This was repainted into JNR standard red and cream livery before entering revenue service.

From March 2012, two new Isumi Class 300 diesel cars entered service on the line. Built by Niigata Transys, these feature transverse seating and toilets.

On 11 October 2012, a former JR West KiHa 28 DMU car, KiHa 28 2346, was delivered to the line. This is used in conjunction with the KiHa 52 125 car.

In January 2013, a JR East KiHa 30 DMU car, KiHa 30 62, previously used on the Kururi Line was delivered to the line.
