The standard-class seating arrangement used in the original 253 series sets was unusual for Japanese limited express trains in consisting of European-style fixed four-seat bays.
The seats were later rearranged in a fixed unidirectional layout facing four-seat bays in the centre of each car between 2003 and 2004.
The green (first class) cars in the original three-car sets were classified as KuRo 253 or KuRo 253-100.
The KuRo 253 cars had ten rows of 1+1 seating at a seat pitch of 1,090 mm (43 in), with seats angled to face the windows, together with one 4-person compartment.
The KuRo 253-100 cars had eight rows of seats arranged in a mixture of 2+1 and 1+1 at a seat pitch of 1,340 mm (53 in), together with one 4-person compartment.
