Japan Airport Customs Rules 2026: Alcohol, Meds & Prohibited Items

Planning a trip to Tokyo involves more than just picking the Best Time to Visit Japan. While you might be excited about the cherry blossoms, Japan Customs does not mess around with "illegal" imports. What is a simple cold medicine in your home country could be considered a banned stimulant here. Whether you are landing at Narita or Haneda, knowing these rules is critical.

Red Channel vs. Green Channel

Like most international airports, Japan uses a color-coded channel system. However, they are shifting heavily towards digital declarations.

🟢 Green Channel (Nothing to Declare): Use this if you are within your duty-free limits and carry no restricted items. Note: You must still scan your declaration QR code at the kiosk.
🔴 Red Channel (Goods to Declare): Use this if you exceed allowances (alcohol, tobacco) or are unsure about an item (e.g., medications, food).

Important: Even if you have "Nothing to Declare," Japan Customs requires everyone to submit a declaration form (either paper or digital via Visit Japan Web).

Duty-Free Allowances (Per Adult)

If you are 20 years or older, you can bring the following items without paying taxes:

Item	Limit (Per Person)
Cigarettes	200 cigarettes OR 50 cigars OR 10 packs of heat-not-burn tobacco
Alcohol	3 bottles (approx. 760ml each)
Perfume	2 ounces (approx. 56ml)
Other Goods	Total market value up to ¥200,000 (approx. $1,300 USD)
Cash	Up to ¥1,000,000 (or equivalent) without declaration

The "Big Ban" / The Trap: Medications 💊

The biggest trap for travelers is medication. Japan has zero tolerance for stimulants, even if they are legally prescribed in the US or Europe.

The Danger Zone: Medications containing Pseudoephedrine (common in cold meds like Sudafed or Vicks inhalers) and Amphetamines/Methamphetamines (like Adderall, Vyvanse) are STRICTLY PROHIBITED.

The Consequence: Bringing these into Japan, even with a doctor's note, can lead to immediate arrest and deportation.

The Rule: If you need to bring restricted prescription meds, you must apply for a "Yunyu Kakunin-sho" (Import Certificate) weeks before your trip.

Banned & Restricted Items List

Do not pack these items under any circumstances. Japan's bio-security measures are extremely strict regarding food and plants.

Illegal Drugs: Cannabis (CBD oil is also very risky and mostly banned), cocaine, etc.

Certain Medications: Adderall, Vyvanse, Sudafed (containing pseudoephedrine).

Meat & Animal Products: Beef jerky, sausages, ham (even vacuum-sealed). Japan’s quarantine beagles will find them.

Fresh Produce: Most fruits and vegetables are banned to protect local agriculture.

Obscene Materials: Uncensored pornography (magazines, DVDs).

Counterfeit Goods: Fake designer bags or watches.

Official Source: For the full and official list of prohibited items, please refer strictly to the Japan Customs Official Website.

Fines & Payment

Confiscation: Banned items (like meat or fruit) will be confiscated immediately. You will not get them back.

Fines: Penalties for bringing in illegal meat products can be up to 3 million yen (approx. $20,000 USD).

Arrest: Carrying banned stimulants (drugs) usually results in detention, not just a fine.

The Connectivity Lifesaver

Customs in Japan can be stressful, especially with the language barrier. You will need internet access immediately upon landing to access the "Visit Japan Web" app or use translation tools.
