Can you book a private room on the Tokyo–Osaka Shinkansen? From 1 October 2026, yes: ¥42,390 solo or ¥60,790 for two (Supreme Class)

This week's news · Checked 2026-09-23

Update 2 Oct 2026 — it has started. Supreme Class began running on 1 October (Travel Watch report, 1 Oct; JR Central's Supreme Class page). One rule on the official page matters for families: in the two-person room (Car 7), a companion aged 6 or under needs no ticket ("in case the accompanying passenger is 6 year old or younger, s/he does not need any tickets"). So one parent with a child aged 6 or under pays ¥60,790 in total (≈ RM1,571) one way Tokyo–Shin-Osaka, against ≈ ¥75,290 for two adults. The room still takes two people only. A companion aged 7 or over needs their own Shinkansen ticket for the same train (any seat class).

Short answer. Yes, from 1 October 2026, but only for one or two people. JR Central introduces Supreme Class, a tier above the Green Car, on Nozomi trains on the Tokaido and Sanyo Shinkansen: private rooms with a lockable door (opened with a registered IC card), reclining seats with leg rests and seat heating, dimmable lighting, dedicated luggage space and Wi-Fi. Two types: a solo room in Car 10 and a two-person room with a sofa in Car 7. Official JR Central fares (regular season, one way, checked 30 Sept 2026): Tokyo–Shin-Osaka ¥42,390 per person (solo) or ¥60,790 for the two-person room, plus the second passenger's own Shinkansen ticket. Booking is only through Smart EX (membership required). It starts on about 12 trains a day, planned to reach about 30 by the end of the fiscal year.

What it means for you.

• Not for a family of four. The biggest room takes two. An ordinary reserved seat Tokyo–Shin-Osaka is ≈ ¥14,500; the solo room is about three times that. For four people, ordinary seats together remain the sensible choice.
• When it makes sense: a couple without children who want 2.5 hours of sleep or work undisturbed, or a parent with a baby or small child worried about crying (a locked room, sound stays in). Two adults: ¥60,790 + ¥14,500 ≈ ¥75,290 (≈ RM1,946) one way. One adult + a child aged 6 or under: ¥60,790 (≈ RM1,571).
• JR Pass holders: don't plan on Supreme Class. The JR Pass official page on train accommodations says "Reservations cannot be made for the Supreme Class", and JR Central sells it only through Smart EX. The pass also doesn't cover Nozomi on its own: you need the separate NOZOMI MIZUHO Ticket, ¥4,960 Tokyo–Shin-Osaka (JR Pass: train accommodations · NOZOMI MIZUHO Ticket, checked 6 Nov 2026). Pass-vs-tickets sums, 8 days before the price rise: JR Pass price increase, 1 Oct.
• Ordinary Shinkansen tickets Tokyo→Shin-Osaka for your dates, paid in RM: Tokyo–Osaka Shinkansen ticket on Klook (price varies by date; checked 23 Sept 2026).
