Is Lorazepam Legal in Japan?
Conditional — quantity threshold applies
Lorazepam (Ativan) is allowed into Japan for personal use without a permit, provided you carry no more than 90 mg in oral (non-injectable) form. Above that threshold, or for any injectable form, you must apply for a Yakkan Shoumei import certificate supported by a doctor's letter before travel.

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.
