The trains are designed by Ken Okuyama Design,[2] with exterior painted with sapphire blue to match with the blue sky of the Izu Peninsula. Two eight car sets were manufactured, by Kawasaki Heavy Industries' Hyogo factory (cars 1 to 3)[3][4] and Hitachi's Kasado factory (cars 4 to 8).[5]
Set RS1 operated a trial run on November 21, 2019,[2] and the trains entered service on March 14, 2020,[6] the day after the 251 series Super View Odoriko sets were retired.
The car bodies are made of aluminum, and the trains use three phase motors and VVVF inverters.[1] Each car has one door per side; cars 3, 5, and 7 are fitted with pantographs, with the one on car 5 being for emergency use.
The trains are formed as eight-car sets, with five motored and three trailer cars. Car 1 faces towards Izukyū-Shimoda and car 8 towards Tokyo.[1]
Car 1 is designated as a "premium green car" with a 1+1 private seating layout. The fully power-reclining seats, made of leather and equipped with leg rest and luggage space under each seat, can be swiveled towards the window side for the view of Izu's seaside.
Cars 2 to 3 are designated as "green cars" with private compartment seating for groups of 4 to 6 people and are priced higher than the "premium green car". Seats are arranged in transverse seating for the 4 person compartments and individual seatings for the 6 person compartments. All private compartments have the electrical power outlets.
Car 4 is designated as the cafeteria, with an open-style kitchen, counter seats, and table seats.
Cars 5 to 8 are designated as regular "green cars"; passenger accommodation consists of 2+1 seating throughout. Each seat is equipped with power outlets and can be reclined. Two single seats on car 5 are equipped with belts for wheelchairs.[7]
All cars, except cars 2 to 4, have a luggage area at the end sections and overhead, and restrooms are available in cars 2, 3, and 7, with multi-accessible toilet located at car 5. All seats except private compartments are equipped with personal reading lights, and all cars feature Wi-Fi connection.
