How to Prepare for a Stem Cell Therapy Consultation in Osaka

Published 2026.10.14 7 min read

Hello, I am Dr. Hidenori Shimada of Grand Green Osaka Umekita Clinic in Osaka, Japan.

If you live outside Japan, or live in Japan but are not fluent in Japanese, a consultation about adipose-derived stem cell therapy can feel like a lot to prepare for. The treatment involves collecting a small amount of your own fat tissue, culturing the mesenchymal stem cells it contains at a specialized facility, and returning them by intravenous infusion. This article explains how to prepare for a first consultation at Grand Green Osaka Umekita Clinic in Osaka so that the conversation with your doctor is as useful as possible.

Short answer: prepare questions, records, and realistic expectations

The most helpful preparation is to gather your medical history, write down what you hope to understand, and learn the basic framework in which this treatment is offered in Japan. Adipose-derived stem cell therapy is a self-pay (non-insured) regenerative treatment. Whether it is appropriate for you, what it may involve, and what risks or side effects are possible can only be judged by a physician after an individual consultation. It is not a replacement for standard medical care, and no outcome can be promised.

Understand what the treatment is, and what it is not

Stem cells are cells that can renew themselves and differentiate into other cell types, which is why they are involved in maintaining and repairing tissues. Mesenchymal stem cells are a type of somatic stem cell found in fat tissue and bone marrow. Laboratory and clinical research has reported that they may release anti-inflammatory substances and growth factors that support tissue repair, but research is still developing and results in studies do not automatically apply to every individual.

Fat tissue is often used as a source because it is considered to contain a relatively large number of mesenchymal stem cells and can be collected through a small incision under local anesthesia. Because the cells come from your own body, the risk of rejection is considered lower than with donor cells, although this does not mean that risks are absent. Infection, bleeding at the collection site, and reactions during or after infusion are examples of issues a doctor should explain to you.

Know how this treatment is regulated in Japan

In Japan, regenerative medicine is provided under the Act on the Safety of Regenerative Medicine, which requires clinics to submit a treatment plan that has been reviewed by a certified committee and notified to the Ministry of Health, Labour and Welfare. Cell culture is carried out at facilities that meet the relevant requirements. This framework governs how the treatment is offered, but it does not mean that the treatment is approved as a pharmaceutical product or covered by public health insurance.

For international patients, this raises practical points worth asking about during your consultation:

Which regenerative medicine provision plan covers the treatment you are being considered for
Whether the treatment is offered as a self-pay service and what the fee structure includes
What the clinic does if you have a concern after you return home
How your consent is obtained, and whether documents are available in a language you can read

Prepare your records and questions before you visit

A doctor can discuss options more meaningfully when they understand your background. Before your visit, consider collecting the following information in a single folder, ideally with English or Japanese copies, or both if available:

A list of your current diagnoses, past surgeries, and ongoing treatments
Names and doses of all medications and supplements, including any blood thinners
Known allergies, especially to local anesthetics or antibiotics
Recent test results, imaging reports, or referral letters from your regular doctor
Any history of cancer, infection, or immune conditions, which your doctor will want to review carefully

It also helps to write down your questions in advance. Useful examples include what the evidence says about your specific concern, what the typical sequence from fat collection to infusion looks like, how many visits are expected, how long you may need to stay in Osaka, and what follow-up is available. Asking how the doctor would approach your situation if you decided not to proceed is also reasonable. A good consultation should leave you feeling informed rather than pressured.

Plan the practical side of visiting Osaka

Because cells are collected first and cultured before infusion, the process generally takes place over more than one visit. Ask the clinic early about the expected timeline so that you can think through travel dates, time away from work, and accommodation. Grand Green Osaka Umekita Clinic is located in the Umeda area, which is convenient to reach from major train stations and from Kansai International Airport. The clinic also provides an information page for international patients, and you can ask about language support when you book so that you know what to expect on the day.

Travel also raises its own medical questions. If you are flying shortly after a procedure, or if you have a condition that is monitored closely at home, discuss this with your doctor beforehand and share the plan with your regular physician where possible.

Questions to settle before you decide

There is no need to decide on the day of your first consultation. Many patients find it helpful to take written information home, compare it with trusted public resources, and discuss it with their usual doctor. Consider whether you understand the procedure steps, the possible risks and side effects, the full cost, and the limits of what the treatment can be expected to do. If something remains unclear, ask again until it is explained in a way that makes sense to you.

Adipose-derived stem cell therapy is one option within regenerative medicine, and it is not suitable for everyone. Your doctor may advise against it, or suggest other approaches, depending on your health.
