This is the question travellers get wrong most often, and the confident answers in travel forums contradict each other. The rule itself is short, and it splits cleanly in two.

Can I wear or use what I bought?

If it is a consumable, it has to leave Japan unconsumed. If it is anything else, you can use it in Japan — the National Tax Agency says so directly: even if you have been using a non-consumable in Japan up to the point you depart, as long as it is ultimately taken out of the country, you can still receive the customs check.

So the shirt you bought and wore, the shoes you have been walking in, the camera you took on the trip: all fine.

What counts as a consumable?

The Q&A names three kinds and leaves the category open: food and drink, medicines, cosmetics, and other consumables. The test is whether the thing gets used up, not what shop it came from.

That puts clothes, shoes, bags, watches and electronics outside the category. It puts snacks, drinks, sweets, medicine, skincare and make-up inside it.

Because the category ends with “and other consumables”, treat anything that is depleted by use as being on the consumable side, even if it isn’t one of the three named kinds.

What happens if I eat or use one up?

Two things, and the second one surprises people.

First, you cannot get the customs check for that purchase. The item as bought is no longer leaving the country, so the check is not available for it.

Second, you must not use the terminal at all in that situation. If you have consumed all or part of a consumable, the Q&A tells you to skip the tax-free terminal and tell a customs officer at the counter instead. This is an instruction, not a suggestion. Our airport procedure guide covers where the terminal and the counter are.

On the shop’s side, the purchase record is cancelled — the shop sends cancellation data for it. Nothing is collected from you: you paid the tax at the till, and the purchase simply stays an ordinary taxed one. Tax is collected from a traveller in a different situation — where you did receive the customs check and then did not take the goods out of the country.

One missing item can cost a whole receipt

This is the part worth understanding before you open anything.

Customs does not check item by item. It checks one purchase record at a time, and a purchase record is one sale — in practice, one receipt. If even a single item on that receipt is not with you, every item on it fails, including the ones you still have.

The National Tax Agency’s own example makes the stakes plain:

○○ SHOP

5 December 2026, 10:40

---

Item A¥3,000have it

Item B¥75,000have it

Item C¥13,000missing

---

Total¥91,000

No refund on any of it — all ¥91,000

Shop D

6 December 2026

---

Item d¥8,000missing

No refund

Shop E

7 December 2026

---

Item e¥7,000have it

Refund is fine

A ¥13,000 item you no longer have takes a ¥75,000 item down with it, because they were rung up together. Split across two receipts, the same two purchases would have been independent.

The rule is about possession, not about why. The Q&A’s condition is simply that an item is not in your possession at the check — eaten, left at the hotel, posted home, given away, it makes no difference. That is also why this is not a consumables-only rule.

Don’t throw away the box

This applies to everything, consumable or not, and it is the rule most likely to catch out someone who packed carefully.

If you separate packaging that is part of the item from its contents, or throw away packaging that carries the details identifying the item — a model number, for instance — customs may not be able to identify it as something bought at a tax-free shop. If they cannot identify it, you may not be able to get the check.

The Q&A’s advice is to leave things as they were at purchase until you have departed. That is what makes the check go smoothly.

Note what this is not: the Q&A’s rules on packaging materials were removed in the July 2026 revision, so there is no sealed-bag requirement in the current rules. Keeping the original box is about letting customs recognise the item, not about keeping a seal unbroken.

Once you know what you can and cannot use, the remaining step is the check itself at the airport — see Japan’s tax-free airport check.
