JR Central will introduce fully lockable private cabins on the Tokaido Shinkansen starting Oct. 1, 2026 [1].
The move marks a significant shift in premium rail travel in Japan, targeting high-end travelers who require more privacy and customization than the existing Green Car amenities provide [1, 3].
Marketed as "Supreme Class," the new service will feature both one-person and two-person cabins on N700S fleet trains [1, 2]. A one-way trip between Tokyo and Shin-Osaka in a one-person cabin is priced at ¥42,390 [1]. These cabins are located in specific cars, with car seven hosting a two-person cabin and car 10 featuring a one-person cabin [1, 2].
Reservations for the new service open on Sept. 15, 2026 [1]. At launch, the company will operate approximately 12 daily round-trip services across both the up- and down-lines [1]. JR Central plans to expand this capacity to about 30 daily round-trip services by the end of fiscal year 2026 [1, 3].
This is the first time the line has offered such private accommodations in 23 years, following the retirement of the 100 series private cabins [1]. The company intends to further diversify its seating options by introducing half-private seats in fiscal year 2027 [1].
JR Central said the goal is to provide a space that exceeds current luxury standards to differentiate the line's offerings [1, 3].
“A one-way trip between Tokyo and Shin-Osaka in a one-person cabin is priced at ¥42,390.”
The introduction of the Supreme Class reflects a strategic pivot toward the ultra-premium market to offset fluctuating travel patterns. By pricing these cabins significantly higher than standard luxury fares and introducing lockable spaces, JR Central is moving away from mass-transit efficiency toward a 'boutique' rail experience, catering to business executives and wealthy tourists who prioritize seclusion over speed.
