Domestic Connection in Japan: Where Does the Check Happen?

The customs confirmation happens at the airport you leave Japan from. From November 1, 2026 that confirmation is what releases the tax on a ¥5,000 purchase, so it is not the shop and not the domestic airport in between — Japan Tourism Agency (checked August 19, 2026).

With a domestic leg in the itinerary, the shop and the terminal can end up in different cities, so the goods and the passport have to travel together to the end.

Where exactly do you do the confirmation?

At the international departure airport. You present the passport the purchase was registered against, and the terminal returns one of two results: a Green judgment lets you walk on, a Red judgment means showing the goods — Japan Customs (checked August 19, 2026).

A domestic flight inside Japan is not a departure. Nothing happens at that airport for tax-free purposes, and there is nothing to do when you land there either.

Why does a domestic leg complicate it?

Because it separates the purchase from the confirmation by a flight. Under the old system the discount was finished at the register, so the itinerary did not matter. From November 1 the money depends on a step that happens at the very end.

It also puts your purchases into the baggage system earlier. If the goods go into a checked bag for the domestic leg and stay there, they are out of reach when the terminal asks for them.

What does not change with a connection?

• The minimum is ¥5,000 before tax, per buyer, per shop, per day. That reads as ¥5,500 on a tax-included tag.
• The 90 days run from the purchase date, not from the domestic flight or the international one.
• Receipts from different shops never combine, so buying in two cities does not add up.
• The refund is one eleventh of the tax-included price.
• Separate shipment was abolished at the end of March 2025, so posting goods ahead to the departure city takes them outside the system.

How should you plan the itinerary?

You bought in one city and fly out of another

Keep every receipt and the passport together to the end. The terminal at the departure airport is the only place the confirmation happens.

Your domestic leg has a checked bag

Keep the purchases in hand luggage if you can. A Red judgment at the end means producing the goods, and a checked bag cannot be opened at the terminal.

Your connection is tight

Add margin at the international airport rather than the domestic one. The confirmation is a step you cannot skip and cannot do later.

You are shopping on the morning of the domestic flight

That is fine, and the 90-day clock has barely started. What matters is that the goods stay reachable through both flights.

You are buying in two cities

Each shop is judged separately, so a little in each city is the same failure as a little in each shop. Concentrate the shopping in one place.

You are staying overnight between the two flights

An overnight stop puts a hotel between the purchase and the confirmation. Keep the goods and the passport in the bag you take to the room, not in one you leave with the front desk.

You are flying out on a different day from the domestic leg

The 90 days run from the purchase date, so a day or two in between costs nothing. What it does add is one more chance for the goods to end up in the wrong bag.

You are changing airports by train, not by air

It makes no difference to the rule. The confirmation still happens where you leave Japan, and the goods still travel with you.

What is unannounced about the terminals as of August 19, 2026?

Where the customs terminals sit in each airport, how many there are, and whether they are before or after security are all unannounced as of August 19, 2026. Nothing on the Japan Customs (checked August 19, 2026) site gives the layout yet.

Because of that, the honest advice for a connecting itinerary is to arrive early at the international airport rather than to plan around a specific location. Whether a handling fee is deducted is also unannounced as of August 19, 2026; the tax inside a tax-included price is one eleventh, and whether anything comes off it would appear via the Japan Tax-free Shop Association (checked August 19, 2026) or the Japan Tourism Agency (checked August 19, 2026).

Questions people ask

Where do I do the tax-free confirmation with a domestic connection?

At the airport you leave Japan from, not at the domestic airport in between.

Do I need to do anything at the domestic airport?

No. A domestic flight is not a departure from Japan.

Should the purchases go in my checked bag for the domestic leg?

Keep them in hand luggage if you can. A Red judgment at the end requires showing the goods.

Can I post my purchases to the departure city instead?

No. Separate shipment of tax-free goods was abolished at the end of March 2025.

Does the 90-day deadline change if I connect?

No. It runs from the purchase date regardless of the itinerary.

Can I combine receipts from two cities?

No. Receipts from different shops never combine.

What happens if I miss the terminal at the last airport?

For purchases from November 1, 2026 there is no refund to collect later.

Where are the terminals located?

Unannounced as of August 19, 2026, including whether they sit before or after security.

How much time should I allow?

More than usual. The layout is unannounced as of August 19, 2026, so arriving early at the international airport is the only reliable margin.

Does it matter which airline I use for the domestic leg?

No. The rule follows the departure from Japan, not the carrier.

Can I do the confirmation early at the shop instead?

No. The shop registers the purchase; the confirmation happens at the customs terminal on the way out.

What if I buy something at the domestic airport?

It is judged like any other shop, and it still needs the confirmation at the international airport before you leave.

Do I show the receipts at the domestic security check?

No. The domestic leg has nothing to do with the tax-free process.

Can someone else carry my purchases on the domestic flight?

The goods have to be with you when the terminal asks for them, so keep them in your own luggage.

Does the shop need to know my departure airport?

No. The shop registers the purchase against your passport; where you leave from is decided later.

Is a connection through a third country different?

The confirmation still happens at the Japanese airport you depart from. What happens after you leave Japan is outside this system.
