Japan Restricted & Prohibited Items
Japan has strict customs rules. The most common issue for tourists is medication — especially cold medicine containing pseudoephedrine. Violations result in confiscation, fines, and in serious cases, arrest.
General guidance only — entry requirements change frequently. Verify with official Japanese government sources before traveling.
🚨 Most common mistake: Sudafed and NyQuil
These common US/UK cold medicines contain pseudoephedrine, which is a controlled substance in Japan. Every year, travelers are stopped at customs with Sudafed in their bag. Confiscation is automatic. Do not bring them — leave them home or switch to a pseudoephedrine-free alternative before traveling.
💊Medications — Most Common Mistake
Pseudoephedrine (Sudafed, DayQuil, NyQuil)
ProhibitedContains pseudoephedrine — a controlled substance in Japan. Even a single box can result in confiscation and fines. Switch to a pseudoephedrine-free formula before traveling, or leave it home.
Codeine cough syrup
ProhibitedCodeine is a controlled substance in Japan. Available only by prescription in Japan. Do not bring over-the-counter codeine products.
Stimulants (Adderall, Vyvanse)
ProhibitedAmphetamine-based ADHD medications are strictly illegal in Japan. Bringing them, even with a prescription, can result in arrest. No import process exists for these.
Ritalin / Concerta (Methylphenidate)
RestrictedUp to a 30-day supply is allowed for personal use with a copy of your prescription. Quantities over 30 days require a Yunyu Kakuninsho (import certificate).
Sleeping pills / sedatives (high dose)
RestrictedMany are allowed with a prescription, but quantities over a 1-month supply require an import certificate (yunyu kakuninsho) from the Ministry of Health. Bring the minimum needed.
Prescription drugs (under 1 month supply)
AllowedMost prescription medications under a 1-month supply are allowed with your original prescription document. Carry in original packaging with your name visible.
🥩Food & Agricultural Items
Fresh meat (all types)
ProhibitedAll fresh, frozen, and cooked meat products are prohibited without a phytosanitary certificate — which individual travelers cannot easily obtain. This includes cured meats, jerky, sausages, and pork products.
Fresh fruits and vegetables
ProhibitedMost fresh produce is prohibited to prevent agricultural pests. Commercially sealed, heat-treated canned or packaged items are generally OK.
Soil, plants with roots
ProhibitedPlant material with soil attached (potted plants, cut flowers with roots) requires inspection and is usually confiscated.
Commercially packaged snacks / candy
AllowedSealed, commercially packaged food products from your home country are generally fine to bring in reasonable quantities.
🔪Weapons & Blades
Swords and long blades
ProhibitedSwords and blades over 15 cm are heavily regulated. Antique Japanese swords require a "Sword Carrying Certificate" and must be declared. Leave decorative swords home.
Pocket knives over 6 cm
ProhibitedFolding knives with a blade over 6 cm are illegal to carry in public in Japan. Many camping knives fall in this category.
Firearms and ammunition
ProhibitedStrict prohibition. Declaring a firearm at customs requires advance approval from the National Police Agency — not possible for most travelers.
💰Cash & Valuables
Cash over ¥1,000,000 (≈$6,500)
RestrictedYou must declare cash (any currency) or monetary instruments exceeding ¥1,000,000 equivalent at customs. Failure to declare can result in seizure. Use the red customs lane and complete Form C.
Commercial goods / items for resale
RestrictedItems bought abroad to resell in Japan must be declared and may attract import duty. Personal use items up to ¥200,000 are duty-free.
Departure Tax (Sayonara Tax)
RestrictedFrom July 1, 2026, the international departure tax increases from ¥1,000 to ¥3,000. This is typically included in your airline ticket price.
New Tax-Free System (Nov 2026)
RestrictedStarting Nov 2026, Japan moves to a "refund-at-airport" system. You pay full price (including tax) at shops and collect your 10% refund at the airport upon departure.
