Doctor letter & quantity rules
- 1No certificate or permission is required if you carry ≤ the quantity threshold AND the form is non-injectable (oral only).
- 2If you are above the threshold OR carrying an injectable form, apply for a Yakkan Shoumei (import certificate) before travel.
- 3Carry the prescription bottle in original pharmacy packaging with the patient label legible.
- 4We recommend a doctor's letter listing your diagnosis, drug name, daily dose, and trip length — even when below the threshold, customs may ask.
Above the threshold? Apply for a Yakkan Shoumei (import certificate) — the MHLW equivalent of an import permit for psychotropics over the personal-use limit.
