Cold Medicine and Patches in Japan: What Changes in 2026?

Medicine is bought to be used, and from November 1, 2026 you can start using it in Japan. The catch is the customs terminal, where a Red judgment asks for the goods. Here is how to handle both.

Medicine is the category you buy because you need it now. From November 1, 2026 the sealed bag is gone, so a qualifying purchase of ¥5,000 before tax can be opened and used while you are still in Japan — Japan Tourism Agency (checked August 19, 2026).

The other side of that freedom is the airport. A Red judgment at the customs terminal means showing the goods you bought — Japan Customs (checked August 19, 2026).

What actually changed for medicine?

The general goods and consumables split is abolished, so medicine and non-medicine in one shop count as one total.
The sealed bag is gone, so you can take what you bought during the trip.
The former daily ceiling on consumables is abolished, removing the old ¥500,000 limit on a single day.
The tax returns after the customs confirmation rather than at the register.

Medicine sat under all four of those, which is why this category feels different from November 1 in a way that, say, a handbag does not.

Why does using it create a problem?

Because the confirmation can ask for the goods, and a course of tablets you finished is not something you can present. The old sealed bag made that impossible; nothing replaces it.

This is not a rule against using medicine. It is a practical consequence of the refund moving to the end of the trip.

How do you handle both at once?

Take what you need. That is what the change allows.
Keep the box and the blister pack. An opened item you still have can be shown.
Do not finish a registered course before departure if you can avoid it.
Keep the registered purchases reachable at the airport, not in a checked bag.

What has not changed?

The minimum is ¥5,000 before tax, per buyer, per shop, per day — ¥5,500 on a tax-included tag.
Receipts from different shops never combine, so comparing three drugstores and buying a little in each still fails.
The 90 days run from the purchase date.
The refund is one eleventh of the tax-included price.
Separate shipment was abolished at the end of March 2025, so the boxes travel with you.

When does this come up?

You got a cold on the trip

Buy what you need and take it. If the purchase was registered, keep the packaging rather than binning it with the last dose.

You are stocking up for home

Concentrate it in one shop on one day. The daily ceiling is gone, so quantity is not the constraint.

You are buying patches for a sore back

Using some and carrying the rest is the ordinary case, and an opened box you still have is presentable.

You are buying eye drops for the flight

A small item is unlikely to reach the threshold alone. From November 1, 2026 it adds to whatever else you buy in that shop that day.

Your basket mixes medicine and cosmetics

They count as one total in that shop on that day, which usually makes the basket qualify more easily.

You are buying for family at home

The goods have to leave Japan with you. Anything handed over inside Japan is outside the refund.

You are on a long stay

The 90-day window and the chance of finishing the box push the same way: buy closer to departure.

You are unsure which rate applies

The till applies it. How the reduced rate is treated for tax-free purchases is unannounced as of August 19, 2026.

You have a connecting flight home

The confirmation happens where you leave Japan. Keep the medicine in the bag that stays with you.

You want to compare prices first

Compare, then buy in one shop. Receipts from different shops never combine.

You are asked at the till whether you want tax free

Say yes before payment is finalised. A purchase not registered then cannot be attached afterwards.

What is unannounced as of August 19, 2026?

What the terminal does when registered goods cannot be produced is unannounced as of August 19, 2026, which is exactly the case a finished course of medicine creates. Nothing on the Japan Customs (checked August 19, 2026) site sets out the handling.

Whether a handling fee is deducted, how many days the refund takes, and how the reduced rate is treated are unannounced as well; answers would appear via the Japan Tax-free Shop Association (checked August 19, 2026) or the Japan Tourism Agency (checked August 19, 2026). Rules about carrying medicine across borders belong to each country's own authorities and are not covered here.

What if I finish the box before flying?

A Red judgment asks for the goods. What follows when they cannot be produced is unannounced as of August 19, 2026.

Should I keep the packaging?

Keeping it is safer, because an opened item you still have can be shown.

Is there a daily limit on how much medicine I can buy?

The former daily ceiling on consumables is abolished on November 1, 2026.

Yes, in the same shop on the same day from November 1, 2026.

Receipts from different shops never combine toward the minimum.

How much comes back?

Do I need my passport at the drugstore?

Yes, before payment is finalised, if you want the purchase registered.

Yes, from the purchase date.

How many boxes may I take out of Japan?

That is a question for the authorities of the countries involved, not for this system.

Can I give some to a friend in Japan?

Can I open a box at the hotel and still claim?

Opening is allowed from November 1, 2026. Keep the box so the goods can be shown if asked.

What this system looks at is the purchase and the goods. Anything about prescriptions belongs to the relevant health authorities.

For the threshold and the bag, yes. The split that used to separate categories is abolished on November 1, 2026.
