Short answer
Standard Yamato TA-Q-BIN accepts parcels up to 200 cm in three-side total and 30 kg, with additional single-side restrictions. Ask staff to measure and weigh your packed suitcase. If it exceeds a maximum, do not assume paying more solves it: repack and recheck, carry it subject to your transport’s rules, or find storage that confirms it can take your bag.
Do this now
- 1Measure the packed suitcase.
Measure its outside height, width and depth, then add them. Include protruding wheels and handles as a conservative practical check; ask staff for the final measurement.
- 2Weigh it and identify the service.
Ask whether the refusal is due to the bag, this particular service or this drop-off location.
- 3Repack only if the result can qualify.
If practical, split contents into suitable parcels, then have each parcel remeasured and weighed. Do not assume an overweight case is accepted for a surcharge.
- 4Confirm an alternative before leaving the counter.
If it still cannot be shipped, plan to carry it or check a storage location’s actual bag conditions and collection hours.
Current standard TA-Q-BIN limits
Yamato’s English table lists a maximum three-side total of 200 cm and a maximum weight of 30 kg. Both conditions matter. The longest side is limited to 170 cm; for parcels requiring a particular orientation, such as ones that cannot be turned upside down, the maximum side is 100 cm.
A lower size band is not the overall maximum: Size 160 allows up to 160 cm and 25 kg, while Size 180 allows up to 180 cm and 30 kg. Yamato applies the higher category when size and weight fall into different bands. Final acceptance also depends on the contents and packing.
These are TA-Q-BIN limits, not permission for every drop-off service. Confirm the service and location with staff. The Haneda/Narita luggage-delivery page also states 200 cm and 30 kg as its overall limits.
Slightly over a band or a maximum
If you are only over a lower size band, ask whether a higher permitted category applies. If you are over the maximum size or weight, remove or split contents if feasible and have staff check again.
Practical suggestion: do not force a bulging case shut or rely on your home scale being exact. A second parcel needs its own suitable packing and acceptance; ask for the actual total charge.
Clearly over, or cannot repack
Do not hand it over expecting an exception. Ask Yamato whether it has a suitable service for the actual dimensions, weight, contents and destination; this guide does not verify a larger alternative service.
If you carry it yourself, check your train, bus, taxi or airline’s baggage arrangements separately. If you only need it out of your hands, ask a hotel or staffed storage location about that specific bag. Storage does not transport it onward.
If that fails
A locker is an option only if the bag fits through its opening and inside the compartment. The checker is a planning aid, not confirmation of a particular available locker. For an unusually large case, get a staffed storage location’s acceptance before travelling there.
If you need a paid storage fallback, check a specific ecbo cloak listing for availability, opening hours, bag conditions and collection time before booking. This is a normal non-affiliate link. Do not assume a storage address also accepts courier deliveries.
What not to do
Do not assume a storage provider accepts any size or weight. Do not confuse a train’s oversized-baggage rule with a courier’s shipping limit, or leave the suitcase at a counter that has refused it.
