Why You Can’t Bring Big Suitcases on the Bullet Train Anymore

Last updated: February 5, 2026

Are you planning to travel to Kyoto or Osaka by Bullet Train with a giant suitcase? Be very careful. A strict rule introduced in 2020 could cost you money if you are unprepared. If your luggage has total dimensions (length + width + height) between 160cm and 250cm, it is legally classified as “Oversized Baggage.” For reference, most large airline check-in suitcases fall into this category, while small carry-ons are fine to place on overhead racks.

If you have an oversized bag, you MUST reserve a specific seat equipped with a designated baggage area (usually located in the last row of the car). The seat reservation itself doesn’t cost extra, but you must book it in advance when buying your ticket. You cannot just hop on any train and hope for the best.

If you bring a huge bag without this specific reservation, you will face consequences. You will be charged a 1,000 yen fine on the spot, and the conductor may force you to move your bag to a designated area in a completely different car. To avoid starting your trip with a fine and a hassle, measure your suitcase before you head to the station!
