Suitcase sizes checked against Japan
Pick the size or the model you own. Each page gives the four verdicts — coin locker, Shinkansen, takkyubin and airline carry-on — from the maker’s published dimensions.
By inches
The label used in Japan and the United States. It refers to the height of the shell, usually with the wheels included.
By capacity in litres
The European label. Capacity says nothing directly about whether a case fits a locker, so these pages give the external size a case of that capacity usually has.
By height in centimetres
If you have measured your own case, start here: height is the dimension that decides most locker and Shinkansen verdicts.
Last checked: 2026-09-09 — Rules and prices change. Coin locker dimensions in particular vary from station to station, so treat the sizes here as a guide and check the official page before you travel.
