Luggage Rules on the Shinkansen

Shinkansen bullet trains limit luggage by size. Most suitcases ride free in the overhead racks and at your feet. A bag above a set size needs a reserved seat with oversized-luggage space, and a bag above a larger limit cannot go on the train at all. The Shinkansen is the high-speed rail network linking Tokyo with cities across Honshu and into Kyushu. JR East, JR Central, JR West, and JR Kyushu set the rules.

For most travelers, the rule depends on one measurement. Add the bag’s length, width, and height. If the total is 160 cm or less, you can board without a reservation. Bags over 160 cm and up to 250 cm need a reserved seat on the Tokaido, Sanyo, Kyushu, and Nishi-Kyushu lines. Bags over 250 cm must go by delivery service. These rules were current as of December 27, 2025, so check the operator websites before you travel.

How big a bag can you bring

The limits apply to each piece of luggage, and the first measurement is the three-side total. JR operator pages set the boundary at "over 160 cm," so a bag that measures exactly 160 cm falls in the no-reservation group.

The general carry-on limits from JR East are a three-side total of up to 250 cm, a length of up to 2 m, and up to 30 kg per piece. Each adult may bring up to two pieces, and JR East does not count umbrellas, canes, or handbags toward that two-piece limit. Items that exceed these limits cannot be carried on.

Measuring a bag at home saves a surprise at the station. Hard-shell cases sold as 28 inches are often just under 160 cm on a three-side measurement, while 29-inch and 30-inch cases often go over it. Use a tape measure, add the three dimensions with the wheels and handles folded in as they normally sit, and compare the total to the 160 cm line.

Which trains need a reservation

The oversized-luggage reservation applies to the Tokaido, Sanyo, Kyushu, and Nishi-Kyushu Shinkansen. The requirement applied to those four lines as of December 27, 2025.

The Hokkaido, Tohoku, Akita, Yamagata, Joetsu, and Hokuriku trains have no oversized-luggage seats. Ordinary luggage on those lines goes in the racks or at your feet, and an oversized bag has no reserved space to use. If your route includes one of those lines, plan the bag’s route with that limit in mind, or ship it ahead.

Some items are exceptions to the size rule. Sports equipment and musical instruments can come on board without a reservation regardless of size, and so can wheelchairs and strollers. For a bag over 250 cm, the rules state that it cannot be carried on board, and the rules do not say whether a golf bag or instrument case of that size counts as an exception. Ask the staff at the station before you arrive with a bag that size, or ship it.

Booking space for an oversized bag

An oversized bag requires a reserved seat that includes oversized-luggage space. You book that seat before you board, through the same channels as any other reserved seat. Online booking is available through the SMART EX app, at ticket machines in stations, and at Midori no Madoguchi ticket windows. The reservation system started with rides from May 20, 2020, so it has been in place for several years.

Reserve early. Oversized-space seats are limited, and the rear of the car is the typical location for the space behind the reserved seat. The space holds one oversized item per seat and accepts luggage up to the 250 cm three-side total. Ordinary reserved cars and Green cars include these seats, but not every car has them.

Passengers in non-reserved cars cannot bring an oversized bag into those cars, because they have no oversized-luggage seats. If you hold a Japan Rail Pass, the reservation still applies to the bag. The pass does not cover the oversized fee.

The reservation has no separate charge beyond the regular seat fare.

The fee for an unreserved oversized bag

Carrying an oversized bag without a reservation costs ¥1,000 including tax. Check the current fee on the JR East or JR Central baggage page before you travel, or ask at the ticket window.

The ¥1,000 charge and the no-fee rule for luggage within the limits do not conflict. The no-fee rule covers bags within the carry-on limits and bags with a reservation. The ¥1,000 charge covers an oversized bag with no reservation.

Deck spaces on Tokaido and Sanyo trains

The rules changed in 2025. JR Central and JR West announced on April 4, 2025 that some deck-area spaces on 16-car Tokaido and Sanyo trains would hold luggage for passengers without a reservation. The change took effect July 1, 2025, as a trial that runs "until further notice." The companies said the end date would be announced separately. The details of the trial are set out in one report.

Each train has six spaces, located on the decks of cars 3, 5, 7, 9, 13, and 15. You lift an anti-fall bar to store a bag, and you share the spaces with other passengers, so expect to take turns. The official limit for these spaces is 160 cm three-side total, as the JR Odekake baggage page describes. Oversized bags still need a reservation and cannot go in these spaces.

JR Central and JR West gave a reason for the change. They said hand luggage is generally expected to go in the overhead racks, but tourism-related demand for luggage space had grown. If you travel with a medium-sized bag on a Tokaido or Sanyo train without a reservation, check whether the deck spaces are still in use before you rely on them. Sending a bag ahead is the more dependable plan if you need guaranteed space.

Sending bags ahead instead

Forwarding takes a bag off the train. A bag shipped ahead does not ride in the car, so it needs no oversized-luggage space. It suits travelers with large suitcases, golf bags, or bulky gear, and anyone who wants to travel light between cities. The trade-off is cost and timing. You pay for the shipment, and the bag arrives later than you do.

JR East Logistics operates Hakobyun Quick (?????Quick), a same-day rail courier that sends parcels on the nearest train with space. Parcels must be handed in up to 30 minutes before departure, and the receiving station holds them for pickup. The service accepts pieces up to 120 cm three-side total and 30 kg. The fee depends on the larger of the size tier or the weight tier, and the operator’s fee table includes tax:

The fee depends on size and section. At Morioka Station, the operator’s counter is open 10:00 to 17:30 and accepts cash only, so plan around those hours. Check the operator’s page for the full list of stations and current terms before you book.

Hakobyun Quick moves a parcel the same day along the rail line. It does not hold a bag for several days, so it works best when you ship a bag to a station where you will be on the same day.

Takkyubin for multi-day shipping

Takkyubin is the Japanese term for door-to-door parcel delivery, and the main carriers are Yamato, Sagawa, and Japan Post. Yamato’s product is TA-Q-BIN. These carriers take bags between hotels and homes. They also take bags to and from stations, and they can move a suitcase across the country in a day or two. Hotel front desks and convenience stores commonly accept the bags for shipment. Japan Rail Pass coverage does not apply to takkyubin.

Carrier prices depend on three things: the size class, the route, and the date. The rates you find online vary for that reason. Sample rates include a Tokyo to Kyoto starting price of ¥1,650, a Yamato Size 160 bag on the same route at ¥2,630 for next-day delivery, Tokyo to Osaka at about ¥2,200, and Tokyo to Sapporo at about ¥3,400 with two-day delivery. Get a current quote from the carrier before you commit.

Delivery usually arrives the next day within Honshu and in about two days to Hokkaido, Kyushu, or Okinawa. Ship the bag the day before you need it, and expect it to arrive after you do. Check the carrier’s declared-value and liability terms before you ship anything valuable.

Planning the bags for the trip

Start by weighing each bag. The rules set three limits: 160 cm, 250 cm, and 30 kg. Each adult is limited to two pieces. Keep the bags at 160 cm or less whenever you can, and use the racks and the space at your feet. For a bag between 160 cm and 250 cm, book a reserved seat with oversized space on the four covered lines, and book it early. Plan to ship a bag over 250 cm ahead. The same goes for any bag on a Hokkaido, Tohoku, or similar line.

Build the trip around the bag rather than the other way around. A traveler with two large suitcases on a Tokyo to Kyoto to Hiroshima route can reserve one oversized seat with space and send the second bag by takkyubin between hotels. A traveler on a Hokkaido route with bulky gear can plan to ship everything ahead and carry a day pack.

Key Takeaways

• Measure every bag first: Keep the three-side total at 160 cm or less to board without a reservation, and treat anything over 250 cm as a bag that must be shipped.
• Reserve oversized space early: Bags over 160 cm up to 250 cm need a reserved seat with oversized-luggage space on the Tokaido, Sanyo, Kyushu, and Nishi-Kyushu lines. Those seats are limited.
• Confirm the ¥1,000 fee before you travel: An unreserved oversized bag costs ¥1,000 including tax, so check the current JR fee on the official baggage page.
• Check the deck spaces on the day: The Tokaido and Sanyo deck spaces became a trial from July 1, 2025. They hold only bags up to 160 cm, so do not count on them for oversized luggage.
• Ship bags that will not fit: Use Hakobyun Quick for same-day rail parcels up to 120 cm and 30 kg, or use takkyubin for multi-day moves, and send each bag the day before you need it.
