Shinkansen Luggage Rules for Big Suitcases
Short answer: measure your suitcase — if length + width + height is 161–250 cm, book a "seat with an oversized baggage area" (no extra cost) on the Tokaido, Sanyo, Kyushu or Nishi Kyushu Shinkansen. Without it you pay JPY 1,000 on board; over 250 cm cannot board.
| Total of 3 sides | Where it goes | Reservation |
|---|---|---|
| Up to 160 cm (most check-in suitcases) | Overhead rack, at your feet, or deck storage area | Not needed |
| 161–250 cm | Space behind the last row, shared by the 5 seats in that row | Required — free, choose "seat with an oversized baggage area" |
| Over 250 cm | Not allowed on board | — |

How to book it
- At a JR ticket office: say "seat with an oversized baggage area".
- At reserved-seat ticket machines or online booking sites for those lines: pick that seat type.
- With a JAPAN RAIL PASS: ticket office or the JAPAN RAIL PASS reservation site.
- Seats open one month ahead and can sell out on busy trains. Non-reserved cars have none.
Travel without the suitcase
JR Central also runs a paid same-day luggage delivery from stations or hotels. Or send it ahead with a delivery company — see sending your suitcase to the airport.
Quick answers
Do I need to reserve space for my suitcase on the Shinkansen?
Only if its three sides add up to 161–250 cm, on the Tokaido, Sanyo, Kyushu and Nishi Kyushu Shinkansen. Reserve a 'seat with an oversized baggage area'; it costs nothing extra.
What if I board with a big suitcase and no reservation?
JR Central charges a JPY 1,000 baggage fee and the conductor decides where it goes. If the train is full you may be asked to take another train.
Can I reserve the luggage seat with a JAPAN RAIL PASS?
Yes. Ask at a JR ticket office or use the JAPAN RAIL PASS reservation site.
