Shinkansen Luggage Rules: The 160cm Limit Explained
Quick answer
Bags up to 160cm (height + width + depth) need no booking. Bags over 160cm need a free oversized-baggage seat reserved in advance. As of June 2026, skipping the reservation can cost a 1,000 yen handling fee.
Is my suitcase too big for the Shinkansen?
Most suitcases are fine. The rule only affects very large bags. To check, add the three sides of your bag together: height plus width plus depth. As of June 2026, this is how the totals are treated on the Tokaido, Sanyo, and Kyushu Shinkansen lines.
| Three-side total | What you need | Cost |
|---|---|---|
| 160cm or less | Nothing special; carry it on board | Free |
| Over 160cm, up to 250cm | An oversized-baggage seat, reserved in advance | Free to reserve |
| Over 250cm | Not allowed on board | Send it another way |
A common large suitcase (around 75cm tall) often totals close to 160cm once you add all three sides. Measure before you travel so you know which row you fall into.
How do I measure my bag correctly?
Measure the bag at its widest points, including wheels and handles, because those count too.
- Measure the height from the floor to the top, including wheels.
- Measure the width at the widest point.
- Measure the depth (front to back), including any handle that sticks out.
- Add the three numbers. That total decides your category.
If the total is 160cm or less, you do not need to do anything special. If it is more, read the next section.
How do I reserve an oversized baggage seat?
An oversized-baggage seat is a normal reserved seat placed next to a luggage space, usually at the back of the train car. As of June 2026, reserving it is free. You can book in these ways:
| Booking method | How |
|---|---|
| Online reservation site | Choose a seat marked for oversized baggage when booking |
| Ticket machine at the station | Select the reserved seat option and the oversized-baggage seat type |
| Ticket office (Midori no Madoguchi) | Ask staff for an oversized-baggage seat |
| Travel agent | Ask them to book the oversized-baggage seat type |
Book early, because the number of these seats per train is limited. After booking, you store your large bag in the space behind the last row, next to your seat.
What happens if I do not reserve?
If your bag is over 160cm and you board without a reservation, staff handle it on the spot. As of June 2026:
- Staff may charge a 1,000 yen handling fee.
- They place your bag in a space of their choosing, if room is free.
- There may be no suitable space on a busy train, which causes delay and stress.
It is far easier to reserve in advance, or to send the bag ahead so you travel light.

Rules and fees can change. Check the official JR Central or JR West site before you travel, and book your oversized-baggage seat as early as you can.
What if my bag is over the limit, or I want to travel light?
If your bag is over 250cm, or you simply do not want to carry it on a crowded train, send it ahead instead. Luggage forwarding services pick up a bag at one hotel or a convenience store and deliver it to your next hotel, often by the next day. This lets you ride the Shinkansen with only a small bag.
This is a popular choice for travelers moving between cities. You drop the bag off the day before, then collect it when you arrive. It avoids the size rule entirely and keeps the trip relaxed. Check delivery times in advance, since some routes take more than one day.
FAQ
How is the 160cm Shinkansen luggage size measured?
You add the three sides of the bag together: height plus width plus depth. As of June 2026, if the total is 160cm or less, you can carry it on board with no special booking. If the total is more than 160cm and up to 250cm, you need an oversized-baggage seat. Bags over 250cm are not allowed.
Which lines does the oversized baggage rule apply to?
As of June 2026, the rule applies to the Tokaido, Sanyo, and Kyushu Shinkansen lines (the routes linking the Tokyo, Osaka, Hakata, and Kagoshima areas). Other Shinkansen lines do not have the reservation rule, but check the official site, because rules can change.
Does the oversized baggage seat cost extra?
No. As of June 2026, reserving an oversized-baggage seat is free. You book a normal reserved seat that sits next to a luggage space, at no added charge. The only cost comes if you bring an over-160cm bag without booking, which can add a 1,000 yen handling fee.
What if I did not reserve and my bag is over 160cm?
As of June 2026, staff may charge a 1,000 yen handling fee and place your bag in a space they choose, if room is available. To avoid this, reserve an oversized-baggage seat before you board, or send the bag ahead with a luggage forwarding service.
Do strollers and sports gear count as oversized baggage?
As of June 2026, strollers and wheelchairs are not counted as oversized baggage and do not need a special seat. Large sports gear and instruments are judged by the same three-side total, so measure them. Check the official rules if you are unsure.
