The trains are built by Kawasaki Heavy Industries to a "retro-future" concept, with black front ends intended to evoke images of a steam locomotive.[3] The exterior livery includes orange and green highlights evoking the satsuma oranges and olives for which the region is famous.[2] Each vehicle is built at a cost of approximately 250 million yen, financed partially by national infrastructure investment subsidies.[2] The trains will operate at a maximum speed of 130 km/h (80 mph) in service, although they have a maximum design capability of 140 km/h (85 mph).[3] Tilting capability enables the trains to negotiate curves with a radius of 600 m or more at a speed 30 km/h (20 mph) higher than the limit for conventional non-tilting trains.[3]

The three-car sets, numbered E1 to E3, include "Green" car (first class) accommodation in half of one car, and are formed as follows, with one motored car and two non-powered trailer cars.[4]
