We've been traveling to Japan with injectable medication for years — Doug, our co-author, manages Type 2 diabetes and takes Ozempic. We've navigated Japanese customs together with his insulin on more than a dozen trips, and with his Ozempic on seven of them. Everything in this post comes from those experiences.
We have begun receiving more questions about traveling to Japan with GLP-1 medications than almost any other topic — and it's easy to understand why. Millions of travelers are now on Ozempic, Wegovy, or Mounjaro, and Japan is one of the world's great long-haul destinations. The question of what you can bring, and how, is one worth answering carefully.
The good news is that these medications are generally allowed into Japan for personal use, provided you follow a few important guidelines.
Quick Rules for Bringing GLP-1 Medications to Japan
✔ Up to a one-month supply is permitted
✔ Keep medications in their original packaging
✔ Carry a copy of your prescription
✔ Pack all medications in your carry-on
⚠️ More than one month → Yakkan Shōmei required
⚠️ Empty syringes alone may require advance approval
Can You Bring Ozempic, Wegovy, or Mounjaro to Japan?
Yes. Travelers may bring GLP-1 injectable medications into Japan for personal use.
Japan does not prohibit these medications, and they are also prescribed domestically. However, all prescription drugs—whether pills or injections—are subject to Japan’s import regulations.
Zepbound (tirzepatide) — the same active ingredient as Mounjaro, was approved in Japan for obesity treatment and launched there in April 2025. It follows the same import rules as the other medications covered here. See: Eli Lilly Japan product page, Japanese.
Japan’s 1-Month Medication Rule
Under regulations of the Ministry of Health, Labour and Welfare, visitors may bring:
This includes "Pre-filled Syringe" or "Self-injection Kit" medications such as GLP-1 pens.
If you need to bring more than a one-month supply, you must apply in advance for a Yakkan Shōmei (import certificate). The application process is handled through Japan’s official import confirmation system.
What Documentation Should You Carry?
Even if you are within the one-month limit, it is wise to carry documentation in case customs officials ask questions.
Recommended items:
Medication in original packaging with pharmacy label
A copy of your prescription
A doctor’s letter stating:
your name
medication name and dosage
that it is for personal use
Injection pens and needles stored together with the medication
Most travelers are not stopped, but having documentation ensures a smooth entry.
Bringing Injection Pens and Needles
Needles and injection devices are allowed when clearly associated with prescribed medication and within a one-month supply. However, empty syringes or standalone injection devices may be treated as medical devices under Japanese law and can require advance approval—even in small quantities.
You may bring:
pre-filled injection pens (such as Ozempic, Wegovy, or Mounjaro)
necessary needles or syringes for those medications
a small travel sharps container
Always pack these in your carry-on bag, not checked luggage.
Sharps Disposal in Japan
Disposing of needles and sharps in Japan is more manageable than many travelers expect — if you know where to look. Most pharmacies will accept used sharps as a professional courtesy, even if you didn't purchase anything there. That said, we prefer to buy a sharps container at a Japanese pharmacy early in the trip — not because it's required, but because it feels like the right thing to do, and it simplifies the whole process from start to finish.
A capped plastic water or soda bottle is a workable last-resort sharps container until you find a proper disposal point
Beyond pharmacies, dedicated needle disposal boxes are available at major airports including Narita and Haneda, and in accessible (barrier-free) restrooms in department stores and larger train stations. In rural areas, your hotel front desk is usually your best resource — staff will often know the nearest option. If you can't find a disposal point right away, simply carry the capped container until you can.
The one firm rule: never place sharps in regular trash. Japan takes medical waste seriously, and so should we.
Traveling With Refrigerated Medications
Many GLP-1 medications must be kept cool during travel. The FRIO wallet — the cooling solution we use for Doug's medications — works by evaporation rather than refrigeration, keeping medications cool rather than cold. This is exactly what's needed for travel: it won't freeze your medication, requires no ice packs, is TSA-friendly, and is compact enough for any bag.
Importantly, it's effective for the "excursion period" — the window during which medications don't require refrigeration but must stay cool — which is 30-40 days for most injectable medications and 56 days for Ozempic specifically. For most Japan trips, the FRIO alone is sufficient. For extended stays, hotel and ryokan refrigerators (just ask staff) provide additional storage security.
Practical options include:
insulated medication travel cases
reusable cooling pouches (such as FRIO wallets)
hotel refrigerators once you arrive
When You Need a Yakkan Shōmei
You must apply for a Yakkan Shōmei if you bring:
more than a one-month supply of medication
unusually large quantities of syringes
certain restricted medications (not typical for GLP-1 drugs)
Applications are submitted to a regional Japanese quarantine office and typically take 1–2 weeks to process.
What If You Run Out of Medication in Japan?
This is worth thinking through before you go, because replacing a GLP-1 medication mid-trip is possible — but not simple. All major medications — Ozempic, Mounjaro, and Wegovy — are approved in Japan, though primarily for diabetes management rather than weight loss. Getting a one-time prescription as a foreign visitor is not straightforward; most clinics require program enrollment including blood tests and consultations.
That said, options exist for travelers in a genuine bind. A few Tokyo clinics cater to international patients with English-speaking staff, including Hada no Clinic, Bianca Clinic, and the longstanding Tokyo Medical and Surgical Clinic.
For travelers outside Tokyo, Juniper is worth knowing about — it operates as a fully licensed Japanese medical clinic with Japanese-licensed doctors, English-language support, online consultations, and domestic delivery via Yamato within 2-3 days. A consultation and enrollment are still required, so it isn't a quick fix — but it's a real resource.
Pharmacies across Japan can also be helpful in a pinch. Staff may not speak English fluently, but they can often point you toward a nearby clinic or doctor. Showing them your medication packaging goes a long way.
The honest takeaway: bring enough medication for your entire trip, plus a small buffer. Replacement is a last resort, not a backup plan.
The Bottom Line
You can bring Ozempic, Wegovy, or Mounjaro into Japan for personal use without difficulty, as long as you follow Japan’s one-month rule and carry proper documentation.
With a bit of preparation, traveling with these medications is straightforward—and rarely causes any issues at Japanese customs.

Frequently Asked Questions
Can I bring Ozempic into Japan? Yes. Ozempic can be brought into Japan for personal use in quantities of up to one month.
Is Wegovy allowed in Japan? Yes. Wegovy is treated like other prescription medications and is allowed under the same rules.
Can I bring Zepbound to Japan? Yes. Zepbound (tirzepatide) is the same medication as Mounjaro under a different name, approved in Japan specifically for obesity treatment as of April 2025. It follows the same import rules as other GLP-1 medications — bring up to a one-month supply in original packaging with your prescription documentation. No special approval is required within that limit.
Do I need a Yakkan Shōmei for Mounjaro or Zepbound? Only if you are bringing more than a one-month supply.
Can I bring a FRIO wallet on a plane to Japan? Yes, and we travel with one ourselves — it's the only cooling solution we've used for Doug's insulin and Ozempic pens across seven trips to Japan. When we first started traveling with it, we checked with both FRIO and American Airlines about the liquid concern, since the wallet is activated by water and stays cool through evaporation. Both confirmed — and FRIO has since told us directly — that the wallet is TSA-friendly and does not count toward your carry-on liquid limit. We have never had a question asked about it at any checkpoint, including Japanese customs. It's the most practical solution we've found for keeping injectable medications cool through long travel days and transit times.
Do Japanese pharmacies sell GLP-1 medications over the counter? No. GLP-1 medications require a Japanese prescription and cannot be purchased over the counter. Pharmacies can be helpful in directing you to a nearby clinic, but they cannot dispense these medications without a Japanese doctor's order.
This post reflects our research and firsthand experience traveling to Japan with GLP-1 medications. It is intended as practical guidance for experienced travelers, not as medical or legal advice. Regulations governing medication import can change without notice. Always consult your physician before traveling with any prescription medication, and confirm current requirements directly with Japan's Ministry of Health, Labour and Welfare before you travel.
