Whether you’re visiting Japan for a holiday, studying abroad, or moving here long term, figuring out how to travel with HRT medication can feel overwhelming.
Thankfully, thousands of travelers safely bring hormone replacement therapy (HRT) into Japan every year by following the correct procedures before departure. If you’re traveling to Japan with HRT, the rules vary based on the type of medication, how much you’re bringing, and whether you’ll need a Yunyu Kakunin-sho (import certificate).

Can You Bring HRT Into Japan?
Simple answer: yes! Most travelers can legally bring HRT into Japan for personal use.
In most cases, up to one month’s supply of HRT can be brought into Japan without a Yunyu Kakunin-sho, provided it meets certain requirements. These requirements are generally based on the type of medication, how it is administered, and the quantity you’re bringing.
If you’re bringing more than one month’s supply, or your treatment includes injectable medication or syringes, you may need to apply for a Yunyu Kakunin-sho before traveling.
Below, we explain the rules for each type of HRT and how to determine whether you need to apply before traveling.
| Medication | Order | Up to 1 Month | More Than 1 Month |
|---|---|---|---|
| Estrogen tablets, patches & gel | 1 | Generally no Yunyu Kakunin-sho required* | Yunyu Kakunin-sho generally required |
| Testosterone gel & patches | 2 | Generally no Yunyu Kakunin-sho required* | Yunyu Kakunin-sho generally required |
| Injectable HRT (pre-filled syringe or self-injection kit) | 3 | Generally no Yunyu Kakunin-sho required* | May require a Yunyu Kakunin-sho depending on quantity or product type |
| Injectable HRT (vials/ampoules requiring separate syringes) | 4 | Requirements vary — check MHLW guidance | Requirements vary — check MHLW guidance |
| Separate syringes & needles | 5 | May require a Yunyu Kakunin-sho depending on quantity and whether supplied with medication** | Yunyu Kakunin-sho generally required |
*Requirements vary by active ingredient. **Applies if syringes/needles are separate or exceed your treatment needs.
What is a Yunyu Kakunin-sho?
A Yunyu Kakunin-sho (輸入確認証) is an import certificate issued by Japan’s Ministry of Health, Labour and Welfare (MHLW). This is the government department responsible for checking the import of all personal-use medication being brought into Japan from foreign countries.
To bring in certain medication or quantities, you must apply for a Yunyu Kakunin-sho. You can apply for this online through the official Ministry of Health, Labour and Welfare (MHLW) Portal. We’ll walk you through the application process further down below.

HRT Import Rules by Medication Type
Rather than treating all hormone therapy the same, Japanese customs regulations assess each medication based on its active ingredient, dosage and method of administration.
The summary below covers the most common HRT medications. If you’re unsure about your specific prescription, always check the latest guidance from Japan’s Ministry of Health, Labour and Welfare (MHLW) before traveling.
Estrogen HRT (Tablets, Patches & Gel)
Estrogen tablets, patches, and gels generally have the same import rules:
Most travelers can bring up to one month’s supply for personal use, without applying for a Yunyu Kakunin-sho. If you plan to bring more than that, you’ll generally need to apply for the certificate before traveling.
Although these medications are usually treated the same, some may have different import requirements depending on their ingredients, so be sure to check the latest guidance from MHLW beforehand.
Testosterone HRT (Patches & Gel)
Testosterone patches and gels are also treated similarly under Japan’s personal medication import rules:
For most travelers, up to one month’s supply can be brought into Japan without a Yunyu Kakunin-sho. If you need to import more than one month’s supply, you will generally need to apply for one before you travel.
As with estrogen medications, some products may also have additional import requirements depending on their active ingredients, so it’s always worth checking the latest MHLW guidance before traveling.
Injectable HRT (Testosterone & Estrogen)
Both injectable testosterone and estrogen often involve both medication and syringes, so there may be different import requirements for each.
If your medication is a pre-filled syringe or as part of a self-injection kit, you can generally bring up to one month’s supply without applying for a Yunyu Kakunin-sho under current MHLW guidance.
However, if your medication is supplied in vials or ampoules that require separate syringes and needles, the import requirements are a little less clear and may be different from those for pre-filled products. Before traveling, it is always best to check this directly on the MHLW website, or contact the relevant Regional Bureau of Health and Welfare to confirm whether a Yunyu Kakunin-sho is required for your specific medication.

Syringes & Needles
If you want to bring separate (empty) syringes or needles that are not with the associated medication, or you’re carrying more syringes than are needed for your treatment, you will generally need to get a Yunyu Kakunin-sho before arriving in Japan.
How to Apply for a Yunyu Kakunin-sho
You can apply for this from the MHLW Import Confirmation Application Portal. The application portal is in English and also has an easy-to-follow guide in English.
1. Create an Account
To start the process, you will need to create an account and register your personal information.
2. Enter your travel details
Next, you will submit the address details of where you will be staying in Japan, as well as the duration of your stay. You will also need to add your flight details here.
3. Upload prescription
Then you will upload and attach a copy of your prescription showing the medication you want to bring with you to Japan. You will also need to list individually on the website the different medications, as well as quantities, such as the number of tablets that you will bring with you.
4. Upload passport
You will then need to upload a copy of your passport. The details on your passport should match those on your prescription.
5. Submit application
When all of the details have been added to the portal, you are good to go!
6. Wait for approval
When you submit your application for approval, it will be sent to a pharmaceutical inspector. They will review and approve your application, which means you can proceed with bringing your medication with you to Japan.
7. Print certificate
When the review is completed, and your medication has been authorized to enter Japan, you will receive an email notification. You can log back into the portal where you can download your Yunyu Kakunin-sho. You are then all set to bring your medication with you.
What Documents Should You Carry When Traveling With HRT?
It is always best when traveling to Japan to keep your medication in the original pharmacy packaging, and your name on the label clearly matches the name on your passport. It is also best to pack a copy of your official prescription, as well as a signed doctor’s letter explaining the clinical necessity, as you may be asked to present this on arrival.
And, of course, don’t forget to print or have a digital copy of your Yunyu Kakunin-sho if this is required.
HRT and Japanese Customs: What Happens on Arrival?
For most travelers, nothing! Whether you’re bringing up to one month’s supply or more than one month’s supply, you shouldn’t have issues when passing through Japanese Customs, as long as you follow all of the rules for bringing in medication.
However, there’s always a chance customs officers may question you on arrival, so let’s walk you through what to expect should this happen.
Keep Your Medication in Your Carry-On Luggage
Firstly, always pack your medication in your hand luggage. This means that they are easily accessible, should you or Japanese Customs require access to them.
Be Ready to Show Your Documents
Next, present your Yunyu Kakunin-sho; either a printed or digital version should be fine. This will help the Customs staff to know what you are bringing into Japan, why, and that this has already been approved before your arrival.
If you did not apply for an import certificate because of the amount of medication or duration of your stay, you should present your prescription and doctor’s letter to the staff.
Always show staff the original packaging, quantity, and prescriptions to prevent any delays or seizure of your medication.
What if you forgot to get approval before arrival?
If you try to bring medication that requires a Yunyu Kakunin-sho and you are questioned on arrival, the outcome can vary depending on the type of medication that you tried to bring with you. If the medication is a controlled or prohibited substance in Japan, travelers risk detention and criminal penalties.

What If You Need HRT While in Japan?
There are options for obtaining HRT while you are in Japan. In larger cities, access to HRT will be much easier than in hospitals in smaller towns, where there is rarely gender-affirming care. Tokyo and other cities can offer private gender clinics or LGBTQ-friendly medical providers.
Because the Japanese Government recognizes HRT for gender affirmation as an elective treatment, it would not be covered by the Japanese National Health Insurance. This would also mean that any fees for consultations, medication, or treatment would need to be paid for out of pocket. This would affect anyone who is currently living in or looking to move to Japan.
For tourists, the cost would need to be 100% out of pocket. Typically, Japanese hospitals require a psychological evaluation and an official Gender Identity Disorder (GID) diagnosis to prescribe HRT for gender affirmation. However, several private clinics in major cities around Japan operate on an informed consent model, where you can get your prescription on the same day as your appointment.
Conclusion
While bringing HRT into Japan can seem confusing at first, the process is usually straightforward if you prepare in advance and carry the correct documentation. Checking the most up-to-date rules before traveling, keeping medications in their original packaging, and bringing a doctor’s letter and prescription can help avoid unnecessary stress on arrival to Japan, leaving you to focus on what is most important – enjoying your time in Japan.
