Bringing Medication Into Japan
One of the most consequential things to get wrong without realizing it.
🚨
Applies to every nationality, not just US travelers. Common medications — including Adderall and other amphetamine-based ADHD medications, and any form of cannabis/CBD oil — are fully illegal in Japan, even with a valid prescription from your own doctor. Bringing them in can result in arrest, regardless of your passport.
📋 Do you need a Yunyu Kakunin-sho (import certificate)?
Depending on type and quantity, some medications need this certificate applied for before you leave — not on arrival. Apply at least 2 weeks ahead, to the Regional Health Bureau nearest your arrival airport in Japan. Present it to customs on entry. If your medication is classified as a narcotic in Japan (even if legal at home), separate advance approval is required from the Narcotics Control Department — a stricter process than the standard certificate.
