How much is Mounjaro per month in Japan?

It depends on the clinic and the dose. Our fees are JPY 16,500 for one month (4 pens) of 2.5 mg and JPY 28,000 for 5 mg, rising to JPY 68,000 for the highest dose, 15 mg. The consultation is free.

Is the price in Japan per pen or per month?

Our fees are shown per month (4 pens). The Japanese pen holds one dose and is used once a week, so a month is four pens. When you look at another clinic’s figure, check the unit first.

Can I pay with a card issued outside Japan?

Yes. At the clinic we accept cash and major credit cards; for online prescriptions you pay by card through a personal payment link. You are charged in Japanese yen, and the final amount depends on your card issuer’s exchange rate and fees.

Can I buy it tax-free?

No. Under Japan’s tax rules, medicine prescribed by a doctor at a medical institution, including self-pay care, is outside the tax-free and tax-refund scheme.

Can I use Japanese health insurance?

Not for a weight-management prescription. Even if you hold a Japanese health insurance card, this use is self-pay.

Can I buy Mounjaro at a pharmacy or drugstore in Japan without a prescription?

No. Mounjaro is a prescription-only medicine in Japan. It is prescribed by a doctor after a consultation; it is not sold over the counter.

Can I take the three-month plan home?

The three-month plan is 12 pens. Whether you can carry that depends on your destination: several countries allow up to about three months’ supply with a prescription, and some allow less. Check the rule for your country in Taking Mounjaro home from Japan before you decide on a quantity, and carry the prescription certificate.

The short version

Our fees: JPY 16,500 for one month (4 pens) of 2.5 mg, and JPY 28,000 for 5 mg. The consultation is free.
In Japan, a prescription for weight management is self-pay; public health insurance does not cover it. Each clinic sets its own fee, so the figure differs from clinic to clinic.
Possible extras: a prescription certificate in English, JPY 3,000, and delivery within Japan, JPY 1,000 (for online prescriptions).
Prescription medicine cannot be bought tax-free.

“How much is Mounjaro in Japan?” is one of the questions we are asked most often, and the figures published online vary widely. The reason is simple: for weight management this is a self-pay prescription, and every clinic sets its own fee. There is no single national price a patient pays. This article sets out our own fees, what is and is not included, and how published figures elsewhere are put together.

Who this article is for
This is written so that people who are travelling or living in Japan, or who have a trip booked, can check the cost in advance. It is not a suggestion to travel to Japan to obtain medicine: if tirzepatide is available where you live, a doctor at home who can follow you over time is the normal route.

Our fees (tax included)

These are the fees at Almond Clinic (Ichigaya, Tokyo). One month is four pens, because the Japanese pen holds a single dose and is used once a week.

Dose	One month (4 pens)	Three-month plan (12 pens)
Mounjaro 2.5 mg	JPY 16,500 ≈ USD 104	JPY 46,500 ≈ USD 292
Mounjaro 5 mg	JPY 28,000 ≈ USD 176	JPY 81,000 ≈ USD 509
Mounjaro 7.5 mg	JPY 40,000 ≈ USD 251	JPY 117,000 ≈ USD 735
Mounjaro 10 mg	JPY 49,000 ≈ USD 308	JPY 144,000 ≈ USD 905
Mounjaro 12.5 mg	JPY 58,000 ≈ USD 364	JPY 171,000 ≈ USD 1,074
Mounjaro 15 mg	JPY 68,000 ≈ USD 427	JPY 201,000 ≈ USD 1,263

US dollar figures are approximate, at about JPY 159 to the dollar (24 August 2026), and are there only as a guide; they move with the exchange rate. Payment is taken in Japanese yen.

Almond Clinic Mounjaro fees for one month (4 pens) by dose: 2.5 mg JPY 16,500, 5 mg JPY 28,000, 7.5 mg JPY 40,000, 10 mg JPY 49,000, 12.5 mg JPY 58,000, 15 mg JPY 68,000

What is included, and what is not

Item	Fee	Notes
Consultation	JPY 0	The same for a clinic visit and an online consultation
Medicine	By dose (table above)	The original branded product, supplied through Japan’s regular pharmaceutical distribution
Prescription certificate in English	JPY 3,000	Useful at customs if you are taking the medicine out of Japan
Delivery within Japan	JPY 1,000	For online prescriptions delivered to a hotel or address. Flat rate nationwide
Cooler bag	Sold separately	Ask our staff if you need one

People using the medicine for the first time normally start on 2.5 mg. In Japan the dose moves to 5 mg after four weeks, and any increase after that is the doctor’s decision. So the dose is not something you choose from a menu; the doctor decides it after the consultation.

How it works in Tokyo, and our fees

Why the figure differs from clinic to clinic in Japan

In Japan, Mounjaro is approved for type 2 diabetes. Use for weight management is off-label, is not covered by public health insurance, and is paid for by the patient.
Fees for self-pay care are set by each medical institution. That is why the same dose shows a different figure at different clinics.
When you compare, check what the number refers to: one pen or one month (four pens), whether a consultation or first-visit fee is charged separately, and whether tax is included.
As a diabetes medicine, Mounjaro does have an official price set by the government for use under public insurance; that is a reference price for the product, not the fee a self-pay patient is charged.

Published figures in other countries

Readers often arrive with a figure from home in mind. Here is what published figures elsewhere actually are. They are not like-for-like, so we give them without drawing a comparison.

Country	Published figure	What the figure is
United States	USD 1,112.16 per fill	Eli Lilly’s published list price, as shown on its pricing page in October 2026. Lilly states that the amount a patient pays depends largely on their prescription drug insurance plan, and that savings programmes exist for some patients.
Singapore	Around SGD 400–1,200 per month	Not an official price. A range published by private clinics as of August 2026, varying by dose. Consultations are normally charged separately.
Japan	Set by each clinic	Our own fees are JPY 16,500–68,000 per month by dose (table above). Other clinics will differ.

A manufacturer’s list price is not what most patients pay at the counter, and a range advertised by clinics is not a national price. Check the current figure with the pharmacy or clinic you would actually use.

Why the numbers differ: systems, not the medicine

Mounjaro is the same medicine wherever it is dispensed. What a patient pays is shaped by whether it is covered for their diagnosis, how prices are set in that country, the dose, and the exchange rate. None of that is a judgement on any one country’s pricing.

Cost is not the only thing to weigh

Setting our fees out clearly is not the same as advising you to come to Japan for medicine. If you live abroad, there are solid reasons to be treated at home:

If a side effect appears, the doctor who can see you promptly is the one where you live.
The dose is adjusted slowly over several months, and that needs a doctor who follows you throughout.
What you can take home is limited by your own country’s rules — commonly around one to three months’ supply with a prescription — so treatment continues at home in any case. See Taking Mounjaro home from Japan.
The pen may differ from the one you know. The Japanese pen is single-use; several countries use a four-dose KwikPen. See how to use the Japanese Mounjaro pen.

If you were coming to Japan anyway, treat it as one option among others.
