Yes. You do not need to come to Tokyo. Have the online consultation from wherever you are in Japan — Osaka, Kyoto, Fukuoka, Nagoya, Sapporo, Okinawa, anywhere — and we deliver to your hotel or home address in Japan for a flat JPY 1,000. Please contact us at least 3 days before you need it — or at least 14 days for Okinawa and Hokkaido (Sapporo), where delivery takes longer. The only thing we cannot do is ship outside Japan. Lead times by region and how hotel delivery works are in Mounjaro outside Tokyo.

Keep it refrigerated at 2–8°C, in the outer carton. The Japanese labelling also allows room temperature below 30°C for up to 21 days. If a pen has been out of the fridge, you can put it back in, and it then keeps until the expiry date on the carton. Just count the days it spends at room temperature: 21 days in total is the limit. A long flight is fine; the simplest plan is to keep the pens cold for the whole journey (we stock cooler bags). Never freeze them. Details: Travelling with Mounjaro.

Rules differ by airline, but in general yes. A small quantity of medicine for your own use can normally be taken on board. Always pack it in your carry-on bag and never in checked luggage — the hold can get cold enough to freeze the medicine and ruin it. Injectable medicines, needles and medically necessary gel ice packs are allowed through airport security (in the U.S., the TSA requires you to declare them and present them separately for screening), so keep everything in its original packaging and tell the officer at the checkpoint.

Rules are set by the country you are entering, and they change, so please check with your own authorities before you travel. Wherever you are going, three things help: keep the medicine in its original packaging with the pharmacy label, carry an English medical certificate (we can issue one for JPY 3,000), and declare it if asked.

Singapore: the Health Sciences Authority allows travellers to bring in personal medication in the original, labelled packaging with a copy of a valid prescription or doctor’s letter, and quantities above a three-month supply are not allowed; medicines containing controlled substances need HSA approval applied for at least two weeks before arrival, so check the HSA personal-medication pages for your own situation.

United States: keep the original labels and your prescription, limit the quantity to what you personally need, and declare the medicine to a CBP officer on arrival. A prescription certificate is a supporting document, not a guarantee that you will be allowed to bring the medicine in — the decision always rests with the officer on duty.

Rules for seven countries: Taking Mounjaro home from Japan.

No. Under Japanese tax laws, medicines prescribed by a doctor at a medical institution (including self-pay/out-of-pocket treatments) are not eligible for tax-free exemption or refunds.

Yes. Even after you return home you can keep in touch with the doctor and request a further prescription through our official WhatsApp or LINE account. Repeat prescriptions can be delivered to an address in Japan, or collected at the clinic on your next trip — just book an appointment.

Whether you have questions about how the medicine is working, concerns about side effects, or you simply want to plan your next supply, please message us on WhatsApp or LINE at any time.

We dispense genuine brand-name medicine obtained through Japan’s regular pharmaceutical distribution channels. It is prescribed only after a doctor has assessed you in person or online. What you receive is the Japanese pen (name in Japan: マンジャロ (Mounjaro) Ateos): one pen, one injection, once a week. We cannot vouch for Mounjaro bought through other routes, such as online sellers or personal import, because no one can confirm where it came from or whether it was kept cold.
