Taking the Shinkansen with a large suitcase? Measure it before you book.
If Tokyo is part of your route, it also helps to decide your base early. Our Shinjuku vs Ueno hotel-area comparison can help you choose a convenient place to stay before you lock in longer train journeys.
The 160 cm rule
JR Central says baggage with a total of length + width + height of 160 cm or less does not normally require an oversized-baggage reservation.
If the total dimensions are 161–250 cm, you need to reserve a seat with an oversized baggage area on the Tokaido-Sanyo-Kyushu Shinkansen.
What if you do not reserve?
JR Central states that passengers carrying oversized baggage without the required reservation can be charged a ¥1,000 baggage fee.
What if your bag is larger than 250 cm?
Baggage with total dimensions over 250 cm cannot be brought onboard under these rules.
What should first-time visitors do?
- Measure your suitcase before buying the ticket.
- If it is 161–250 cm, reserve the appropriate oversized-baggage seat or space.
- If your luggage is extremely large, consider a luggage forwarding service instead.
- Do not wait until you reach the platform to figure it out.
This matters most on common visitor routes such as Tokyo → Kyoto → Osaka.
