Japan Drug Import Laws
Common US Medications
Banned or Restricted in Japan
Millions of Americans travel internationally carrying medications that are perfectly legal at home — but classified as controlled or prohibited substances at their destination. Japan’s drug import laws are strict. Consequences range from confiscation to imprisonment.
Prohibited — Cannot Bring
Prohibited under Stimulants Control Act. Cannot be imported even with a prescription.
Prohibited under Cannabis Control Act. Most CBD products (oils, gummies) are treated as high-risk at the border.
Conditional — Permit or Limits Apply
Classified as stimulant raw material. Requires NCD permission before travel.
Psychotropic — allowed up to 2.16 g with prescription. Above limit requires NCD permission.
Psychotropic — allowed up to 72 mg with prescription. Above limit requires NCD permission.
Psychotropic — allowed up to 1.2 g with prescription. Above limit requires NCD permission.
Psychotropic — allowed up to 300 mg with prescription. Above limit requires NCD permission.
Psychotropic — allowed up to 6 g with prescription. Above limit requires NCD permission.

Common Questions
Is Adderall legal in Japan?▼
No. Adderall (amphetamine) is prohibited under Japan's Stimulants Control Act. A US prescription does not authorize import — travelers have been detained at customs for personal-use quantities. Speak with your prescriber about Japan-legal alternatives like methylphenidate (Concerta) or atomoxetine (Strattera) before travel.
Is Vyvanse legal in Japan?▼
Vyvanse (lisdexamfetamine) is allowed in Japan only with advance Narcotics Control Department (NCD) permission. Apply at least 14 days before arrival with a doctor's letter detailing diagnosis, dosage, and trip length. Elvanse, Venvanse, Aduvanz, and Tyvense are also lisdexamfetamine and require the same permit.
Can I bring Sudafed to Japan?▼
Sudafed containing pseudoephedrine above 10% is restricted and requires an NCD import permit. Most US Sudafed products exceed that threshold. The simplest plan: leave Sudafed at home and buy Pabron or another Japanese cold remedy at any pharmacy.
Can I bring CBD oil or gummies to Japan?▼
Only CBD products certified THC-free AND pre-approved by Japan's NCD are legal. Most US CBD products do not meet this bar and are routinely seized at customs. When in doubt, don't bring any cannabis-derived product.
Real arrests happen every year to travelers carrying legal US prescriptions.
Japanese customs has zero-tolerance policies for carrying medications like Adderall, Vyvanse, and codeine. A valid US prescription does not protect you in Japan.
