Can You Bring Ozempic to Japan? The Injectable Rule

Yes, you can bring Ozempic to Japan. Semaglutide pens are injectable drugs, so they follow the injectable allowance rather than the ordinary pill rule: up to a 1-month supply of the pre-filled pen or self-injection kit travels in with no certificate needed, as long as it's the pre-filled device itself, not medication drawn separately into a syringe. Carry a copy of your prescription and a doctor's letter alongside it even within that allowance, since customs can ask to see them. Go over a month's supply, and you need MHLW's import certificate, arranged before you fly.

Ozempic is semaglutide delivered through a pre-filled injector pen, exactly the category MHLW's injectable allowance covers: a pre-filled syringe or self-injection kit, up to a 1-month supply, no certificate required. Wegovy, also semaglutide, uses the same style of device and sits under the identical rule — a quantity rule keyed to the device, not the brand name. What it does not cover is medication drawn from a vial into a separate syringe; if your supply comes that way, confirm directly with MHLW before relying on the exemption.

More than a month's supply of Ozempic means applying for the 輸入確認書 (Yunyu Kakunin-sho), the import certificate still widely called 薬監証明 (Yakkan Shoumei), issued by MHLW. Apply through the online portal, the default route since 1 July 2025, at least 14 days before you arrive. Processing takes about 2-3 business days once your application is complete, but build in extra time around Golden Week, Obon, or New Year, when it moves slower.

Two regional desks handle applications by arrival airport: Kanto-Shinetsu Regional Bureau for Narita, Haneda, and Kanto ports (yakkan@mhlw.go.jp), and Kinki Bureau for Kansai, Chubu Centrair, Fukuoka, and Naha (kiyakuji@mhlw.go.jp). At customs, keep the certificate with your prescription and doctor's letter in hand luggage and use the red, declare channel. For a full walkthrough of the application itself, see the Yakkan Shoumei import certificate guide.

Semaglutide and other GLP-1 medications are prescribed in Japan, but the approved indications and insurance coverage don't map directly onto what you're used to elsewhere — don't assume your prescription, dose, or reason for taking it carries over automatically. A prescription written outside Japan cannot be filled at a Japanese pharmacy, so ongoing treatment means seeing a doctor in Japan who can evaluate your situation and issue a Japanese 処方箋 (shohosen). Japan's free-access system lets you go straight to a relevant specialist, no referral gatekeeper required. Whether to start, continue, or adjust GLP-1 treatment is a decision for that doctor, not something to plan around a customs allowance. For how indications and coverage differ, see weight-loss medication in Japan.

Insulin and EpiPens travel under this same injectable allowance — see bringing insulin to Japan if you're managing diabetes alongside GLP-1 treatment. For the broader system — insurance, registering with a doctor, the pharmacy versus drugstore distinction — the health guide and moving to Japan guide go deeper.
