Carry-in limit (guide)
Carry-in limit (guide): up to 3 months' supply per person
You need to check with the HSA in advance. The conditions for not needing prior approval include a prescription from your country of residence, so a Japanese prescription alone may not meet them.
This is for checking the quantity. It does not guarantee that you can bring it in.
What to have ready
- Doctor's certificate: You can add a certificate (¥3,000) in English and your language, showing your name, the medicine, and the quantity, on the same screen as your medicine.
- Original box: Keep the original box with the clinic's label.
- Carry-on prep: Pack it in your carry-on bag, and declare it if you're unsure.
Entry rules
Condition about your country of residence
Only if you meet all of HSA's criteria may you be able to bring in up to 3 months' supply without prior approval. Different rules apply to controlled or prohibited ingredients, and more than 3 months' supply is not allowed.
Leave time for approval
If HSA approval is needed, apply at least 2 weeks before you arrive. Before you buy, ask HSA how a prescription issued in Japan is treated.
Documents and customs
Prescription and pharmacy label
Carry a valid prescription or doctor's letter issued in your country of residence. Keep the medicine in its original packaging, labeled by the dispensing pharmacy with the patient's name, the medicine name, and the quantity.
How customs treats approved medicine
According to HSA, approved medicines do not need to be declared, but you must be able to show the approval email and related documents if inspected. First, check the approval status of your own medicine.
Check your injection pen
Check tirzepatide and all ingredients against HSA's latest document guide. You need to confirm whether approval is required, and whether you have it, for the specific Japanese product, its prescription, and your travel situation.
