Shinkansen reserved vs non-reserved seat: the extra cost

A reserved seat from Tokyo to Shin-Osaka costs ¥530 more than a non-reserved seat on the Hikari or Kodama, and ¥850 more on the Nozomi, in the normal season. The prices are ¥13,870 non-reserved, ¥14,400 reserved on the Hikari or Kodama and ¥14,720 reserved on the Nozomi, for one adult one way. We read them on JR Tokai Tours' seat guide on November 9, 2026.

This page shows how that extra changes with the season and the train, and what it buys. For the full Tokyo to Shin-Osaka price list, see Tokyo to Osaka by Shinkansen. To add up your own rides, use the JR Pass calculator.

Shinkansen reserved vs non-reserved seat: the extra on Tokyo to Shin-Osaka

The table shows the adult one-way price from Tokyo to Shin-Osaka in the normal season, and the extra for reserving.

The extra is our calculation from the three prices. The ¥530 is not a coincidence. JR Central's rule page says the non-reserved express charge is ¥530 below the normal-season reserved charge, whatever day you ride.

A round trip doubles the extra: ¥1,060 on the Hikari or Kodama and ¥1,700 on the Nozomi (our calculation).

How the season changes the extra

The reserved-seat charge moves with the season, but the non-reserved charge does not. For rides between April 1, 2026 and March 31, 2027, JR Central's rule page sets the reserved charge ¥400 higher on super-peak days, ¥200 higher on peak days and ¥200 lower in the off-season than in the normal season.

Because the non-reserved charge stays put, the price of reserving moves by the same amounts. This is our calculation for Tokyo to Shin-Osaka, not a published price list:

The Nozomi row assumes the Nozomi non-reserved price stays at ¥13,870, the figure JR Tokai Tours shows for both trains.

A price rise for the Nozomi reserved seat

JR Central and JR West's notice of October 16, 2026 says the Nozomi and Mizuho reserved-seat express charge rises for tickets bought on or after July 1, 2027, and that the charge for non-reserved seats is not being revised. The notice lists Tokyo to Shin-Osaka rising from ¥14,720 to ¥15,420 for one adult one way in the normal season. Against the ¥13,870 non-reserved price, that makes the extra for reserving the Nozomi ¥1,550 after that date (our arithmetic).

What a non-reserved seat can cost you

A non-reserved seat saves the extra, but it comes with limits that JR Tokai Tours and JR Central state:

• There is no guarantee you will get a seat. JR Tokai Tours lists "no guarantee of a seat" as the drawback of the non-reserved car.
• The non-reserved cars are few. On the Nozomi they are cars 1 and 2. On the Hikari they are cars 1 to 5, on some trains differently. On the Kodama they are cars 1 to 6 and 13 to 16, depending on the train.
• In peak holiday periods the Nozomi runs with reserved seats only. A non-reserved ticket does not get you a seat on those trains; JR Central says you can use the deck of an ordinary car, but you may not be able to board the train you want if it is crowded.

JR Central lists these all-reserved Nozomi periods for fiscal 2026 that had not started as of November 9, 2026:

• November 21 to 23, 2026
• December 25, 2026 to January 5, 2027
• January 9 to 11, 2027
• March 20 to 22, 2027

On those days the Hikari, Kodama and other trains still have non-reserved cars.

What the reserved seat buys

A reserved ticket is valid for the train named on it, so you have a seat on that train. JR Tokai Tours also lists choosing your own seat as a benefit of the reserved car. The reserved-seat ticket goes on sale one month before the ride at 10:00, and smartEX opens reserved seats one year before the ride, with conditions.

If you hold a JR Pass

Pass holders do not pay the extra. JAPAN RAIL PASS states that there is no additional charge for making seat reservations, and that a non-reserved seat on trains other than the Nozomi and Mizuho can be used with the pass alone. So on the Hikari or Kodama, reserving a seat costs a pass holder nothing, and the choice is only about convenience.

The pass is not valid on the Nozomi or Mizuho, reserved or non-reserved. A pass holder who wants the Nozomi buys a separate ticket; the Nozomi extra ticket, route by route lists the price for each section. To see whether a pass pays off against single tickets at all, read JR Pass vs individual tickets.
