A height is a measurement rather than a label, so the 50 cm figure is exact. The width and depth above are the ones a case of that height is usually built to; if you know your own, put them into the checker instead.
What to do about it
- Sending the case from the airport to your hotel is usually the cheapest way to avoid all three problems: hand it in at the arrivals counter and travel with a day bag.
Frequently asked questions
Does a 50 cm tall suitcase fit in a Japanese coin locker?
At 50 × 35 × 22 cm it goes into a medium (m) locker, which is about 34 × 57 × 50 cm inside and costs roughly ¥500–800 a day. Cabinets differ from station to station, so leave a couple of centimetres of margin and have a staffed baggage room in mind as a backup.
Do I need a Shinkansen oversized baggage reservation for a 50 cm tall suitcase?
No. At 50 × 35 × 22 cm its three sides add up to 107 cm, under the 160 cm threshold, so it travels as ordinary baggage on every Shinkansen line and needs no reservation.
What does it cost to send a 50 cm tall suitcase by takkyubin?
At 50 × 35 × 22 cm, 107 cm around, it is a size 120 parcel — up to 120 cm total and 15 kg — which starts at ¥2040 for a parcel that stays inside one region and costs more the further it goes. Airport counters at Narita, Haneda and Kansai take the same sizes for delivery to your hotel.
