What are GLP-1 treatments?
GLP-1 and GIP treatments are medicines used in the treatment of obesity, for weight loss and metabolic control — by medical prescription only. In Japan, the medicine named on this page is approved for type 2 diabetes; using it for weight control is an individual medical decision outside the approved indication.

The treatment
Medical weight loss — Mounjaro (tirzepatide) 2.5 mg · 1 month
- Online consultation with a doctor
- One month of medication
- Reassessment and adjustment at review
- Private treatment (自由診療). Not covered by Japanese health insurance.
- A prescription medicine. Only a doctor can prescribe it, after an individual assessment — there is no direct sale.
- Doses above 2.5 mg are decided in consultation, according to your response to treatment.
- Treatment length and the number of consultations vary case by case and are set by the doctor at each review; the standard is one reassessment per month.
- In Japan this medicine is approved for type 2 diabetes. Using it for weight control is an individual medical decision outside the approved indication, and it will be explained to you before any prescription.
Who it is for
Eligibility is decided by the doctor during the assessment, case by case. There is no automatic criterion, and we do not prescribe from a form.
- Adults from 20 years old
- Your BMI and body composition
- Personal and family health history
- The medicines you currently take
- Recent blood work, where available
When it is not indicated
It is not indicated during pregnancy or breastfeeding, nor for anyone with a personal or family history of medullary thyroid carcinoma or of multiple endocrine neoplasia type 2. Tell the doctor about every medicine and supplement you take, including anything bought without a prescription.
Risks and side effects
The most common effects are nausea, diarrhoea, vomiting, constipation, abdominal pain and reduced appetite. They tend to be strongest at the start and when the dose goes up.
Serious effects are uncommon and include pancreatitis, gallbladder problems and allergic reactions. Seek immediate care for severe, persistent abdominal pain.
The doctor will explain the risks that apply to your case before any prescription. This list is informational and does not replace a consultation.
Why here
Your language, start to finish
Explaining symptoms in Japanese is hard, and in medicine a misunderstanding is expensive. The consultation is in English, with a doctor — not with a translator.
Preventive medicine, not just the scale
The clinic works in preventive diagnostics and longevity. Weight is one marker among several: blood pressure, blood glucose, sleep and body composition are part of the conversation too.
A real clinic, in Tokyo
We are not an app. There is an address in Roppongi, with consulting rooms and staff, and you can come in person whenever you want or need to.
Frequently asked questions
- Do you guarantee how much weight I will lose?
- No. No honest medical treatment guarantees a result, and we do not work with promises of kilos or timeframes. What we offer is individual assessment, monthly follow-up and clarity about the risks.
- Do I need to live in Tokyo?
- No. The consultation is online and we see people anywhere in Japan. During the consultation we agree with you how the medication will be collected or sent.
- How long does treatment last?
- It depends on your response and on the doctor's assessment at each review. There is no fixed term, and stopping is always your decision, discussed with the doctor.
- Does health insurance cover it?
- No. It is private treatment (自由診療), paid in full by the patient. The price on this page already includes tax.
- What language are the prescription and documents in?
- The consultation is in English. Prescriptions and official documents are issued in Japanese, as the law requires, and we explain what each one says.
- What if the doctor says it is not for me?
- It happens, and it is a legitimate outcome of the assessment. The initial consultation is free, so you lose nothing but fifteen minutes — and you leave knowing why.
Start with the assessment
Fifteen minutes, in English, at no cost. If the treatment is not right for you, the doctor will say so.
