JR Central and JR West are introducing a top-tier “Supreme Class” private-cabin service on the Tokaido and Sanyo Shinkansen lines [1].
The move marks the return of private-cabin travel for the first time in 23 years. By offering a luxury experience that exceeds the current Green Car, the rail companies aim to meet the increasingly diversified needs of modern passengers [2].
The new service will operate on the route between Tokyo and Shin-Osaka [3]. The Supreme Class consists of lockable private cabins available for either single passengers or groups of two [4]. These cabins feature reclining seats controlled by tablets, automatic leg-rests, and adjustable lighting [4]. Passengers in this class will also receive complimentary drinks and snacks [4].
Pricing for the luxury service varies by cabin size. A single-person cabin from Tokyo to Shin-Osaka is priced at ¥42,390 [5]. For those traveling in pairs, the price for a two-person cabin on the same route starts at ¥65,000 [6].
JR Central and JR West announced the initiative on June 17, 2026 [7]. Reservations for the new cabins are scheduled to open on Sept. 15, 2026 [8]. The official service start date is set for Oct. 1, 2026 [9].
These developments follow a broader trend of diversifying rail offerings to compete with other high-end travel options. The companies said the service is designed to provide a more exclusive environment for travelers seeking privacy and comfort during their journey [2].
“Private-cabin travel returns for the first time in 23 years.”
The introduction of the Supreme Class signals a strategic shift toward the ultra-luxury segment of domestic travel in Japan. By reviving private cabins and pricing them significantly higher than standard first-class options, JR Central and JR West are targeting high-net-worth individuals and business travelers who prioritize privacy and productivity over traditional shared seating.
