Japan's premium trains are not interchangeable. Supreme Class is a private-cabin product for the Tokaido-Sanyo-Kyushu Shinkansen. GranClass covers selected northern and Hokuriku routes. SPACIA X is built around Nikko and Kinugawa. Shimakaze makes Ise-Shima part of the experience, while Hinotori focuses on Osaka-Nagoya comfort.

SUPREME CLASS: THE PRIVATE-CABIN CHOICE
JR Central states that Supreme Class begins on 1 October 2026. It offers two cabin types: a Car 7 cabin that can accommodate two people and a Car 10 cabin for one person. Published normal-period SmartEX totals include JPY 32,660 from Tokyo to Nagoya and JPY 42,390 from Tokyo to Shin-Osaka for the one-person cabin. Reservations are sold through SmartEX and Express Reservation.
This is the choice when privacy and control of the cabin environment matter more than a lounge-style social experience.

SUPREME CLASS OR GRANCLASS?
GranClass operates on selected Tohoku, Hokkaido, Hokuriku and Joetsu Shinkansen trains. Service levels differ: some trains are sold as GranClass without beverage or light-meal service. Check the service icon for the exact train rather than assuming every GranClass ticket includes the same hospitality.
SPACIA X: SIX SEATING STYLES FOR NIKKO
SPACIA X connects Asakusa with Tobu-Nikko and Kinugawa-onsen. Its choices range from Standard and Premium Seats to Box Seats, Compartments, Cockpit Lounge seats and the seven-person Cockpit Suite. Cafe priority is given to passengers in the Cockpit Lounge, Cockpit Suite and Compartment.

SHIMAKAZE OR HINOTORI?
Shimakaze is the sightseeing choice for Ise-Shima, with departures from Osaka-Namba, Kyoto and Kintetsu-Nagoya. Hinotori is the frequent premium intercity choice between Osaka-Namba and Kintetsu-Nagoya. Choose by destination first, not by which train looks more luxurious in photographs.
