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

From November 1, 2026 a drugstore purchase of ¥5,000 before tax leaves the shop unsealed, so nothing about the packaging keeps it shut until the flight — Japan Tourism Agency (checked August 19, 2026).

The step that meets it later is at departure, inside the 90 days that begin on the purchase date, where a terminal reads the passport and a Red result asks for the goods themselves — Japan Customs (checked August 19, 2026).

Can you open tax-free medicine while you are still in Japan?

Yes, for purchases dated from November 1, 2026, because the sealed bag that used to hold this category closed is abolished on that date. What replaces it is not another wrapper but a step at the end of the trip: the confirmation may ask to see what was registered. A box still in your bag answers that request whether or not it has been opened. A box that no longer exists does not, and how that situation is handled has not been published as of August 19, 2026.

What is recorded in the shop and what is checked at departure?

• In the shop: the passport and the total. The purchase is written against the passport produced while it is being recorded, for that shop and that date — Japan Tourism Agency (checked August 19, 2026).
• In the shop: no seal. From November 1, 2026 nothing in the packaging marks the goods as untouchable during the trip.
• At departure: the passport, then possibly the goods. A Green result lets the traveller move on and a Red result brings the registered items into view — Japan Customs (checked August 19, 2026).

The two ends of that list are what a drugstore basket has to hold together: the freedom to open it, and the ability to produce it, and the second is set out on what the departure terminal looks for.

What changes for a drugstore purchase on November 1, 2026?

• The sealed bag is abolished, so a purchase can be unwrapped between the shop and the flight rather than waiting for the airport.
• The tax is released after the customs confirmation rather than at the register, which is why the goods matter at departure at all.
• The division between general goods and consumables ends, so everything bought by one traveller in one drugstore on one date forms a single total.

Purchases dated up to October 31, 2026 are read under the earlier arrangement, in which the wrapper stayed closed.

What stays the same for a drugstore purchase?

• The qualifying line is ¥5,000 before tax, reached by one traveller in one shop on one date, which shows as ¥5,500 on a tax-included tag.
• The passport is produced while the purchase is being recorded, and a slip taken away without that step does not become a registered purchase afterwards.
• The goods leave Japan with the traveller who bought them, and separate shipment ended in March 2025.

Where does this come up between the shop and the flight?

Something is needed partway through the trip

Buying because the need arrived is exactly what this category is for, and from November 1, 2026 the purchase does not have to stay wrapped to keep its status. The one habit worth forming is keeping the outer box in the bag rather than at the hotel.

An opened box is what you still have

Something opened and still in your possession is something that can be brought into view. The state of the wrapper is not what the confirmation reads; whether the registered item is there to be looked at is.

Nothing is left by the day of the flight

This is the one case the new arrangement creates and does not answer. How a confirmation handles a registered item that cannot be produced has not been published as of August 19, 2026, and the situation is stayed with on when there is nothing left to show.

The outer box went into a hotel bin

Throwing away the carton and keeping the contents leaves a different object from the one that was registered. What would be enough to show in that case has not been published as of August 19, 2026, so the cautious move is to keep the carton with the rest of the purchase.

Medicine and other goods share one basket

From November 1, 2026 they form a single total for that traveller in that drugstore on that date, so the basket reaches the line as one figure. The split that used to sort a basket into two piles is not applied to it.

One small item is all you came in for

A single low-priced item rarely reaches the qualifying line by itself. From November 1, 2026 it joins whatever else is bought at that counter on that date, and what the counter writes down at that moment is described on the moment the drugstore till writes it down.

You want to compare two or three shops first

Comparing costs nothing, and buying in pieces does. Each shop keeps its own total, so a basket assembled across several counters can leave a traveller below the line at every one of them.

The till asks whether you want the purchase registered

That question arrives at the only moment it can be answered. The passport goes across the counter while the purchase is being written down, and a decision postponed to the pavement outside is a decision made.

The suitcase is being packed for the flight home

Registered items that may be asked for are the ones to keep within reach. Anything already travelling in the hold cannot be brought into view, which is followed on purchases that went into the hold.

The trip home runs through a connection

The confirmation belongs to the point where the traveller leaves Japan, not to the airport where the journey finally ends. Registered items therefore stay in the bag that does not get handed over before that point.

The receipt shows two different rates

A drugstore basket can carry lines at different rates, and the till applies them. How the reduced 8% rate is treated inside the tax-free system has not been published as of August 19, 2026, which is traced on the 8% rate that has no tax-free answer yet.

A family member asked you to bring something back

The purchase belongs to the passport produced for it, and the goods leave Japan with that traveller. Handing an item to somebody inside Japan changes who is carrying it out and therefore what can be brought into view at departure.

The stay is long and the shopping day was early

Departure has to fall inside the 90 days that begin on the purchase date. On a long stay, buying nearer the end of it keeps both that window and the box itself on the safe side.

The wrapper comes off in the hotel room

Unwrapping is permitted for purchases dated from November 1, 2026, and the registration is not undone by it. The act itself is followed on unsealing a purchase mid-trip.

The trip crosses October 31, 2026

A purchase dated on or before that day is read under the earlier arrangement, where the wrapper was meant to stay closed until departure. A purchase dated from the following day is read under the new one, so a single trip can hold both kinds of drugstore bag.

Which parts have no published answer as of August 19, 2026?

Two of the gaps sit exactly where this category lives.

• Producing what was registered. How a confirmation handles a registered item that can no longer be brought into view has not been published as of August 19, 2026.
• The reduced rate. How the 8% rate is treated inside the tax-free system has not been published as of August 19, 2026, which is why a mixed drugstore receipt cannot be read to the end here.

The other open points — whether a fee is deducted, how many days the money takes, where terminals stand, whether cash can be collected — belong to the bodies that publish them: the Japan Tax-free Shop Association (checked August 19, 2026) and the Japan Tourism Agency (checked August 19, 2026), with the departure step described by Japan Customs (checked August 19, 2026). Rules on carrying medicine across a border belong to each country's own authorities and are not settled here.

With those points unpublished as of August 19, 2026, the practical part is the part already written down: the purchase is registered at the counter, and the goods travel with the traveller who bought them.

Which questions follow a drugstore purchase?

Can a tax-free drugstore purchase be opened in Japan?

For purchases dated from November 1, 2026, yes; the sealed bag is abolished on that date.

What happens if there is nothing left by the flight?

How a confirmation handles an item that cannot be produced has not been published as of August 19, 2026.

Should the outer box be kept?

Keeping it is the cautious choice, because the registered item is what may be asked for.

Can an opened box still be shown?

Yes. What matters is that the registered item is there, not that the wrapper is intact.

What exactly would be enough to show?

That has not been published as of August 19, 2026.

Do medicine and other goods count as one total?

From November 1, 2026 they do, in one shop on one date for one traveller.

Can one small item reach the line on its own?

Rarely. It joins the rest of that counter's total on that date.

Can purchases at several shops be added together?

No. Each shop's total is read by itself.

Is the passport needed at the drugstore counter?

Yes, while the purchase is being recorded.

Can a purchase be registered after leaving the shop?

The registration happens at the counter, not afterwards.

Can a drugstore purchase be posted home instead?

No. Separate shipment of tax-free goods ended in March 2025.

Does the 8% reduced rate apply here?

The till applies the rates. How the reduced rate is treated inside the tax-free system has not been published as of August 19, 2026.

How much comes back?

One eleventh of the tax-included price, before any deduction that may exist.

How long is there to leave Japan?

90 days, counted from the purchase date.
