Shinkansen baggage size
Add the three outside dimensions and flag the 160 cm and 250 cm planning boundaries, weight, and piece count.
Measure the bagJapan baggage decision center
Will your bag fit the train, locker, and delivery schedule?
Measure the outside dimensions, test the actual storage space, and work backward from hotel check-in before luggage becomes a trip-day emergency.
Check Shinkansen sizeCheck locker fit
Three different constraints
Dimension, space, and time need separate checks.
A bag can be legal on the train but awkward to store, small enough for one locker but not another, or accepted for forwarding without arriving when you need it.
Coin locker orientation
Use the real locker dimensions and test all six ways the suitcase could be rotated, with clearance.
Test locker fitForwarding send-by day
Start at the next hotel check-in and subtract the route-specific quote, buffer, and any missed cutoff.

Use this baggage sequence.
- Measure each piece.
Include wheels, rigid handles, pockets, and the protective cover. - Match the exact service.
Check the train operator, locker bank, carrier counter, route, and cutoff you will actually use. - Separate essentials.
Keep medicine, documents, valuables, electronics, and everything needed through the delivery window. - Confirm the receiving side.
Ask whether the next hotel accepts luggage and which reservation name and check-in date belong on the waybill. - Keep a fallback.
Know the staffed counter, hotel-hold option, smaller day bag, or later train before the first plan fails.
