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:
⚠️ WARNING: Allowances are individual. You cannot pool your alcohol allowance with a friend to bring one expensive bottle that exceeds the individual value limit.
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).

Obscene Materials: Uncensored pornography (magazines, DVDs).
