If you are planning to travel across Japan by Shinkansen (bullet train) with a large suitcase, there are a few important things to consider. 

 Here’s a comprehensive guide to help you navigate the process smoothly.

Baggage Storage Options on Shinkansen

When traveling on the Shinkansen, there are several options for storing your baggage:

Overhead Shelves/Luggage Rack
The overhead luggage rack on the Tokaido Shinkansen (runs between Tokyo and Shin-Osaka) has a depth of about 16.5 in (42 cm).

  • Small carry-on-sized suitcases can be placed on the overhead shelves.
  • A general guideline is that the overhead space can accommodate bags up to approximately 22 in x 14 in x 9 in (56 cm x 36 cm x 23 cm), similar to most airline carry-on restrictions.

Foot Space (Under the Seat or in Front of You)

If your suitcase does not fit on the overhead shelf but is still a standard size, you may store it in front of your seat.

Oversized Baggage Space

Large suitcases exceeding 63 in / 160 cm (sum of height, width, and depth) must be placed in the designated Oversized Baggage Area behind the last row of seats. See below for details.

What is Considered a Large Suitcase?

For Shinkansen, a “large suitcase” is defined as any baggage where the sum of its dimensions (length + width + height) exceeds 160 cm (approximately 63 inches) but is within 250 cm (approximately 98 inches). This size typically corresponds to the checked baggage size on international flights.

What to do if you have a Large Suitcase?

If your suitcase falls into the “large” category, you must reserve a specific type of seat on the Shinkansen that can accommodate your baggage.


Reserving an oversized baggage space incurs no additional charges.
However, passengers traveling with a large suitcase without a reservation will be subject to a baggage fee of 1,000 yen.

1.Reserve Seat with Oversized Baggage Space:
These are seats located at the rear of certain cars, providing extra space behind the seat for your suitcase.

2.Reserve Seat with an Oversized Baggage Compartment:
This is a designated baggage storage area near the train’s entrance or exit doors, where you can securely store your suitcase. These areas are equipped with a locking mechanism that you can operate using a contactless IC card.

You will need an IC card to use the Oversized Baggage Compartment.

How to Reserve a Seat with an Oversized Baggage Compartment

If you have a oversized suitcase, you must reserve a specific seat with an oversized baggage area or compartment.

  1. Online Reservation
    Use services like “SmartEX” or “JR West Online Train Reservation” to book your seat in advance.

  2. Ticket Machines
    You can also reserve your seat at ticket machines available at major train stations.

Japan Rail (JR) Pass holders:
If you plan to use a JR Pass and bought the voucher in US, be sure to exchange your voucher for the pass in Japan first, as you can’t make seat reservations without it.

If you bought the JR Pass through the official Japan Rail Pass website, you can book a reserved seat on the dedicated website before arriving in Japan.
The official website allows you to make seat reservations for Shinkansen and limited express trains online, up to one month before your travel date.

Alternative Solution – Shipping Your Suitcase in Advance

If securing a seat with an oversized baggage space is not possible, or if you prefer a different option, consider shipping your suitcase in advance.

Japan’s Takkyubin 宅急便 (baggage delivery) services, such as Yamato Transport and Sagawa Express, allow you to send your baggage ahead to your hotel or airport. This is a convenient and stress-free way to travel without carrying heavy bags.

・ At major airports like Narita, Haneda, and Kansai, you can find baggage delivery counters where you can send your baggage directly to your hotel.

・ Most hotels in Japan can also arrange this service for you.

・ JAL and ANA offer their own baggage delivery services. Check their websites for details.

This option is especially helpful for travelers who want to move around freely without the burden of carrying heavy baggage.

Essential Tips for Traveling with Large Suitcase on the Shinkansen

  • Early Reservations:
    Seats with oversized baggage space are limited and can fill up quickly, especially during peak travel seasons. It’s advisable to book as early as possible.
  • Baggage Size Limits
    If your suitcase exceeds 250 cm in total dimensions, it cannot be brought onto the Shinkansen.
  • IC Card for Locking: 
    You will need a contactless IC card (such as a Suica or Pasmo) to secure your baggage in the oversized baggage compartment. Make sure you have one ready.
  • Alternative options:
    Consider shipping your baggage in advance from airport or hotel for hassle-free trip.
