Any Shinkansen suitcase with length, width and height adding up to 160cm or more needs a seat reservation with an oversized-baggage area, or the conductor charges a fee.[1] As of early September 2026, this system covers the Tokaido and Sanyo Shinkansen[3] plus the Kyushu and Nishi-Kyushu Shinkansen.[4]
The rule at a glance
| Combined size (L+W+H) | What you must do | Extra cost |
|---|---|---|
| 160cm (63 in) or less[1] | Store at your feet or overhead, no reservation | ¥0 |
| 160cm up to 250cm, reserved[2] | Book a seat with an oversized-baggage area | ¥0 extra |
| 160cm up to 250cm, no reservation | Conductor charges the fee onboard | ¥1,000, tax included[1] |
How to tell if your suitcase is oversized without a tape measure
The 160cm cutoff equals 63 inches, so add your suitcase’s height, width and depth in inches and compare the total to that number.[1]
Its listed size can still sound ordinary at an airline check-in counter, even after adding all three dimensions together.
Strollers, sports equipment such as bicycles, and musical instruments are excluded from this rule entirely, whatever their size.[1]
How to reserve a seat with an oversized-baggage area
Book through Smart EX, EX RIDE, e5489 or the JR Kyushu Train Reservation site when you buy your ticket.[4] Then choose a seat marked for oversized baggage.
These seats go on sale exactly one month before departure and cannot be booked through after-hours or pre-sale requests.[2]
Once aboard, put the suitcase in the compartment or behind the last row of seats in the section you reserved.[1]
Since July 1, 2025, JR West has run a trial allowing its oversized baggage compartment to be used without a reservation.[3] This applies only on some 16-car Tokaido and Sanyo trains.
JR Kyushu Rail Pass holders cannot book this seat type through the pass’s online system and must reserve it at a staffed ticket counter instead.[4]
Reserve on every leg of a multi-city trip, not just the first
If your itinerary uses separate reserved legs, say Tokyo to Kyoto and then Kyoto to Hiroshima, you need a fresh reservation for the entire trip.[2] This covers every leg, not only the first train.
A non-reserved seat cannot be swapped in later just because you are carrying oversized baggage, so skipping the reservation on the second leg still triggers the fee.[2]
What it actually costs: reserve, pay the fee, or ship ahead
Reserving is always free, so the real trade-off is between paying the conductor’s onboard fee and shipping ahead by takkyubin. The comparison below uses Yamato’s Size 160 parcel category, the size band closest to a large checked suitcase.[5]
| Solo, 1 suitcase, Tokyo to Kyoto | Family of 4, 2 suitcases, Tokyo to Shin-Osaka | Couple, 2 suitcases, 3 legs Tokyo-Kyoto-Hiroshima-Tokyo | |
|---|---|---|---|
| Reserve in advance | ¥0 | ¥0 | ¥0 |
| Fee if not reserved | ¥1,000 | ¥2,000 | ¥6,000 |
| Ship ahead by takkyubin | ¥2,630[5] | ¥5,260[5] | ¥5,540[5] |
| Cheapest legitimate option | Reserve | Reserve | Reserve |
The family’s fee is ¥1,000 × 2 suitcases = ¥2,000, payable in cash or by IC card or credit card straight to the conductor.[1]
The couple’s fee across three legs is ¥1,000 × 2 suitcases × 3 legs = ¥6,000.[1] That is more than the ¥5,540 it costs to ship both suitcases to Hiroshima and travel light through the Kyoto stop.[5]
Practical alternatives for first-time visitors with big luggage
Reserving the oversized-baggage seat when you buy your ticket costs nothing beyond the standard reserved-seat fare, and it is the simplest fix for a single city-to-city hop.[3]
For a multi-city trip, sending both suitcases ahead to the next hotel and carrying only a daypack sidesteps the reservation question, at the cost shown above.
Where you stay also changes how far you haul that bag between platform and hotel, so it’s worth comparing Kyoto Station against central Kawaramachi before booking a room (compare both areas here). A few thousand yen for forwarding is a small line item against total trip costs by travel style.
FAQ
Can I use a JR Kyushu Rail Pass to book this online?
No. The pass’s online booking site cannot reserve seats with an oversized baggage area, so pass holders need to go to a staffed ticket counter.[4]
What if my group is traveling with more than one large suitcase?
One reservation covers up to five people in an ordinary car or four in a Green car, but you cannot split the group across different car numbers.[2]
Does the fee change if I only realize I need the space after boarding?
No, it is still ¥1,000 tax included, charged by the conductor, and you store the bag wherever the crew instructs.[1]
