Controlled anabolic steroid; Yakkan Shoumei needed
Details
Testosterone is classified under Japan's Pharmaceutical Affairs Law as a prescription medication. Personal import for travelers requires a Yakkan-Shoumei import certificate filed at least two weeks before arrival via the regional Bureau of Health and Welfare. Without the certificate, customs at Narita / Haneda / Kansai will seize the medication. Therapeutic-replacement dose under 1-month supply has historically been processed sympathetically with a doctor's letter, but the formal rule still requires Yakkan-Shoumei.
Quantity limit
One month supply
Documentation required
- Prescription
- Yakkan Shoumei for larger quantities
Legal reference
Pharmaceutical and Medical Device Act
Leaving with this item
Testosterone is a controlled anabolic steroid; personal export from Japan requires the prescription and stays within personal-use limits.
Practical advice
Keep in original packaging with prescription. Apply for Yakkan Shoumei if staying more than one month.
