Overview
- JR Central and JR West unveiled the new Supreme Class private cabins to reporters on July 8 and plan to begin commercial service on October 1 with about 12 runs a day.
- Tokyo–Shin‑Osaka fares listed on Smart EX put a one‑person cabin at roughly ¥42,390 and a two‑person sofa cabin at about ¥60,790, making prices more than twice standard Green‑car fees.
- Each train will carry two fully enclosed cabins (a one‑person unit in car 10 and a two‑person unit in car 7) fitted with reclining seats, leg rests, dedicated Wi‑Fi, drinks and local snacks.
- Purchasers will buy cabins through the Smart EX reservation service and paying the cabin fee covers the passenger’s ticketing needs; second passengers must hold separate basic tickets.
- JR aims to expand service to roughly 30 daily runs by the end of FY2026 and to introduce six‑seat half‑cabins in FY2027, marking the first private‑cabin addition on the Tokaido route in 23 years and signaling a move to premiumize long‑distance rail travel.
