Tokaido/Sanyo Shinkansen "Nozomi" to Operate All-Reserved During Additional Periods in 2026 Fiscal Year

The Tokaido and Sanyo Shinkansen "Nozomi" service—the fastest and most popular train category linking Tokyo, Nagoya, Kyoto, Osaka, Hiroshima, and Hakata—is well known for offering both reserved and non-reserved seating on standard operating days. However, during periods of anticipated heavy demand, the operating railway companies (JR Central and JR West) routinely convert Nozomi trains to all-reserved (全席指定席) operation to manage passenger flow and reduce overcrowding. As of the latest official announcement from JR West, several additional all-reserved periods have been confirmed for the 2026 fiscal year (April 2026 – March 2027).

This article breaks down the announcement, explains which services are affected, and offers practical guidance for travelers planning Shinkansen journeys during the newly designated periods. For background on Nozomi ticketing and reservation options, see our complete Nozomi Shinkansen guide.

What Happened

On May 21, 2026, JR West published a press release confirming that additional date ranges within the 2026 fiscal year have been designated as all-reserved operation periods for the Tokaido and Sanyo Shinkansen "Nozomi" services. This means that during these specified windows, every seat on every Nozomi train—including what would normally be non-reserved cars—will require a reserved-seat ticket.

All-reserved operation on the Nozomi is not a new practice. JR Central and JR West have historically designated certain high-traffic periods—such as Golden Week, Obon, the year-end/New Year holidays, and select long weekends—as all-reserved. The May 2026 announcement adds periods that were not previously included in the initial 2026 fiscal year schedule, or extends existing windows to cover additional dates.

Why All-Reserved Operation?

The decision to switch Nozomi trains to all-reserved mode during high-demand periods serves several operational objectives:

• Overcrowding prevention: By requiring every passenger to hold a reserved seat, the railway ensures that no more passengers board a train than there are seats available, eliminating standing passengers and corridor crowding.
• Predictable passenger distribution: Reservation data allows the operators to better plan train formations, allocate rolling stock, and manage platform flow at major stations like Tokyo, Shin-Osaka, and Hiroshima.
• Safety and comfort: Reducing crowding in train cars and on platforms improves safety conditions, especially during Japan's hot summer months and holiday surges.

It is worth noting that this announcement is specific to Nozomi services only. "Hikari" and "Kodama" services on the same Tokaido/Sanyo lines are subject to their own separate reservation policies. Travelers who prefer or need non-reserved seating options may still find availability on Hikari and Kodama services during these periods, though demand on those trains will likely increase as a result.

Affected Services

Lines and Train Categories

The all-reserved designation applies to the following:

What Is Not Affected

• "Hikari" and "Kodama" services are not covered by this specific announcement. Non-reserved seating on those categories is expected to remain available, subject to their own policies.
• Green Car and Gran Class seats on Nozomi trains continue to require separate premium reservations regardless of all-reserved designation. The all-reserved policy primarily affects what would normally be the non-reserved ordinary car sections.
• Other Shinkansen lines (e.g., Tohoku, Joetsu, Hokuriku, Kyushu) are governed by separate announcements and are not included in this notice.

What Travelers Should Do

Based on the information in the official JR West announcement, travelers planning to use Nozomi services during the 2026 fiscal year should take the following steps:

1. Check Whether Your Travel Date Falls Within an All-Reserved Period

Consult the official source below or visit the JR West and JR Central official websites to determine whether your intended travel date is within one of the newly added all-reserved periods. The source notice contains the specific date ranges. If you are uncertain, contact JR West or JR Central customer service directly.

2. Reserve Your Seat in Advance

During all-reserved periods, you cannot board a Nozomi train without a reserved seat ticket. Non-reserved seat tickets, including those loaded onto IC cards such as Suica or ICOCA, will not be valid for Nozomi boarding during these dates. You must obtain a reserved-seat ticket (指定席券) through one of the following channels:

• Midori-no-Madoguchi (Green Ticket Windows) at JR stations
• Smartphone apps such as the JR Central "EX-IC" or JR West "e5489" platforms
• Travel agency ticket counters (View Plaza, etc.)
• Online reservation systems operated by JR Central or JR West

Reservations typically open one month before the travel date. During peak periods, popular time slots (morning departures from Tokyo, evening returns from Osaka) may sell out quickly. For tips on securing Shinkansen reservations, see our guide on booking Shinkansen tickets.

3. Consider Alternative Services if You Cannot Secure a Reservation

If Nozomi reservations for your desired time slot are fully booked, consider the following alternatives:

• Hikari services: These stop at more stations than Nozomi but still offer reasonable travel times between major cities. Non-reserved seating may be available on Hikari, though it will be more crowded than usual during peak periods.
• Kodama services: All-station Shinkansen services with the longest travel times but generally the most availability.
• JR Pass holders: Remember that the Japan Rail Pass (JR Pass) does not cover Nozomi services. JR Pass holders must use Hikari or Kodama. This restriction applies year-round, not only during all-reserved periods.

4. Allow Extra Time at Stations

During all-reserved periods, station platforms and ticket gates at major hubs such as Shin-Osaka, Kyoto, and Nagoya may be more congested than usual. Arrive at the station with ample time before your train’s departure, particularly if you need to pick up reserved-seat tickets from a counter or ticket machine.
