- Ask for the exact treatment name and treatment area.
- Confirm how many collections and administrations are included.
- Check which charges are included and which are not.
- Get possible extra charges and refund terms in writing.
- Check the treatment’s Japanese regulatory status separately.
Japan’s Ministry of Health, Labour and Welfare (MHLW) states in its estimated medical expense materials for foreign patients that the final bill may differ from the estimate if examinations or treatment change according to the patient’s condition.[1]
Quote Items to Request
| Item | What the Quote Should State |
|---|---|
| Treatment | Exact treatment or procedure name |
| Treatment area | Body area, joint, side, or other treatment site |
| Cell or tissue source | Patient-derived or donor-derived, and source identified |
| Physician review | Whether pre-travel medical-record review is included |
| Consultations | Remote and in-person consultations included |
| Laboratory tests | Required tests and whether they are included |
| Imaging | MRI, CT, X-ray, ultrasound, or other required imaging |
| Collection | Number of collections and what each collection fee includes |
| Processing | Processing, culture, preparation, transport, and quality-control charges |
| Administration | Number, route, treatment area, and fee per administration or course |
| Anesthesia / sedation | Whether required and whether included |
| Medicines and supplies | Procedure-related medicines and medical supplies included |
| Interpretation | Medical interpretation included and how it is charged |
| Follow-up | Number and type of follow-up visits or calls |
| Storage | Whether required, included period, and renewal fee |
| Tax | Whether applicable tax is included in the total |
| Excluded costs | Charges not covered by the quoted total |
| Estimated total | Total amount in Japanese yen |
| Quote validity | Issue date and expiration date, if applicable |
One detail often causes confusion: how the clinic calculates the price. Confirm whether the quote is per patient, per treatment area, per joint, per administration, per visit, or per treatment course.
Medical Information to Send Before Pricing
- diagnosis;
- recent laboratory results;
- MRI, CT, X-ray, or ultrasound reports;
- original imaging files when requested;
- previous operation records;
- current medicines;
- allergies;
- previous treatments;
- relevant discharge summaries;
- and other medical conditions that may affect treatment.
A useful patient-specific quote should be tied to a medical plan. Once the physician has reviewed the records, ask the clinic to put these details in writing:
- condition being treated;
- treatment area;
- cell or tissue source;
- collection method;
- processing method;
- administration route;
- number of planned administrations;
- required tests;
- expected treatment dates;
- and expected length of stay in Japan.
If you receive a fixed multi-session package before a physician has reviewed the relevant medical records, ask who decided the number of sessions and what medical information that decision was based on.
Costs to Separate in Writing
| Cost | Examples | What to Get in Writing |
|---|---|---|
| Planned | Consultations, tests, collection, processing, administration, follow-up | Amount already included in the estimate |
| Possible extra | Repeat imaging, extra blood tests, another collection, additional administration, longer storage | Price and condition that triggers the charge |
| Unexpected medical | Urgent assessment, emergency imaging, hospitalization, treatment of complications | Who provides the care and who pays |
The quote should be updated when the medical plan changes. Ask for a revised written version if there is a change in:
- number of treatment areas;
- number of administrations;
- cell or tissue source;
- collection method;
- required laboratory tests;
- required imaging;
- storage period;
- another procedure;
- or the number of trips to Japan.
Collection, Processing and Administration Fees
Collection fee
- physician fee;
- procedure-room fee;
- local anesthesia or sedation;
- medical supplies;
- medicines;
- post-procedure observation;
- and the price of a repeat collection if the first collection is insufficient.
Processing fee
- processing facility;
- isolation or preparation;
- cell culture or expansion, if used;
- quality-control or release testing;
- transport between facilities;
- temporary storage;
- and the financial policy if the prepared material cannot be used.
Japan’s Act on the Safety of Regenerative Medicine requires applicable provision plans to include information concerning how cells are obtained and the manufacturing and quality-control methods used for specified processed cells. Outsourced manufacturing arrangements are also addressed by the law.[2]
Administration fee
- number of administrations;
- route of administration;
- treatment area;
- physician fee;
- procedure-room fee;
- imaging guidance, if used;
- anesthesia or sedation;
- nursing and monitoring;
- medical supplies;
- and medicines used during the procedure.
A quote of ¥2,500,000 should say what you are actually buying: one administration, several administrations, one knee, both knees, several treatment areas, or a complete treatment course.
If the clinic gives you a cell number, ask what that number refers to:
- cells per administration;
- total cells for the course;
- a target amount before processing;
- or a final measured amount after processing.
Deposit and Refund Terms
| Stage | Refund Question |
|---|---|
| Before physician review | What amount is refundable? |
| After medical assessment | Which review fees remain payable? |
| After required testing | Which test charges are non-refundable? |
| After collection | Which procedure charges remain payable? |
| After processing begins | Which laboratory charges become non-refundable? |
| After preparation is completed | What amount remains refundable if administration does not occur? |
| Medical rejection | What happens if the physician decides treatment should not proceed? |
| Unusable preparation | What happens if collected or processed material cannot be used? |
| Patient cancellation | What cancellation fee applies? |
| Clinic postponement | Is the payment refundable or transferable? |
| Rescheduling | Can the deposit be moved to a new treatment date? |
For any deposit, get these five details in writing:
- amount;
- due date;
- what it pays for;
- whether it is applied to the final bill;
- and the exact point at which it becomes non-refundable.
Japan Regulatory Records to Verify
If a clinic says the treatment is “approved in Japan,” ask for the exact regulatory basis rather than relying on that phrase alone.
- What is the exact treatment name?
- Under which Japanese regulatory route is it being provided?
- Is there a regenerative medicine provision plan for this treatment?
- What information identifies that plan in the MHLW public database?
- If a regenerative medical product is involved, what is the product name?
- What is the product’s approved indication?
Under Japan’s Act on the Safety of Regenerative Medicine, applicable regenerative medicine provision plans go through the certified regenerative medicine committee framework before submission to the Minister of Health, Labour and Welfare.[2]
A regenerative medicine provision plan is not the same as marketing approval for a regenerative medical product under the Pharmaceuticals and Medical Devices Act. PMDA publishes approved regenerative medical product information separately.[3]
MHLW’s public regenerative medicine system can be used to check information such as the medical institution and treatment listed in a submitted provision plan.[4]
If the clinic says the treatment is part of clinical research, ask for the registration number and search the Japan Registry of Clinical Trials (jRCT).[5]
Regulatory registration, marketing approval, and evidence that the treatment works for your condition are separate issues.
Clinical Evidence to Request
Evidence is only useful if it matches the treatment you are actually being offered. Check whether the study covers:
- your condition;
- the cell type;
- the cell or tissue source;
- the processing method;
- the dose;
- the administration route;
- the number of administrations;
- the type of patients studied;
- and the outcome being claimed.
If the clinic gives you a “success rate,” ask for the details behind that number:
- What exactly counted as success?
- How many patients were included?
- Did they have the same condition?
- How was improvement measured?
- When was improvement measured?
- How long were patients followed?
- Were all treated patients included in the result?
- Was the result published in a peer-reviewed study?
- Or is it based only on the clinic’s own data?
An “80% success rate” could refer to reduced pain, improved walking, a laboratory change, an imaging change, or patient satisfaction. Ask what the clinic actually measured.
The International Society for Stem Cell Research (ISSCR) advises patients to look for scientific evidence supporting the specific stem cell intervention rather than relying on broad claims or patient testimonials.[6]
Travel, Insurance and Follow-Up Costs
| Expense | Amount / Included? |
|---|---|
| International flights | |
| Accommodation | |
| Airport transportation | |
| Local transportation | |
| Meals | |
| Companion travel costs | |
| Medical interpretation | |
| Insurance | |
| Possible flight changes | |
| Possible extra hotel nights | |
| Possible second trip to Japan |
Before booking flights, ask the clinic for the expected dates of:
- initial examination;
- laboratory testing;
- imaging;
- cell or tissue collection;
- processing period;
- administration;
- post-treatment observation;
- and any required in-person follow-up.
Before leaving Japan, ask for copies of:
- treatment summary;
- exact procedure performed;
- treatment date;
- relevant information about the cell-based procedure;
- medicines administered or prescribed;
- follow-up instructions;
- warning symptoms that require urgent care;
- and contact information for the Japanese medical team.
If your doctor at home does not read Japanese, ask whether the clinic can provide an English-language medical summary.
MHLW recommends that international visitors have sufficient private medical insurance because unexpected medical care in Japan can be expensive.[7]
Ask your insurer this question in writing:
If I travel to Japan specifically for this medical procedure and develop a complication related to the treatment, will the policy cover assessment, hospitalization, treatment, an extended stay, or a delayed return flight?
Short-stay visitors should not assume that Japan’s National Health Insurance will pay for private treatment. MHLW lists short-stay foreign nationals among those generally excluded from National Health Insurance eligibility.[8]

Questions to Email the Clinic
- What exact treatment are you proposing for my condition?
- What body area will be treated?
- Has a physician reviewed my medical records before preparing this quote?
- What cell or tissue source will be used?
- What processing method will be used?
- How many collections are included?
- How many administrations are included?
- Is the price per site, per joint, per administration, or per treatment course?
- Which consultations, tests, procedures, medicines and follow-up services are included?
- Which charges are excluded?
- What specific events could increase the final bill?
- How much would an additional administration cost?
- What happens if another collection is required?
- What happens if the prepared material cannot be used?
- What happens financially if the physician decides I should not receive treatment?
- When does each payment become non-refundable?
- What is the exact Japanese regulatory status of this treatment?
- What information can I use to find the treatment in the relevant Japanese public record?
- What human clinical evidence supports this treatment for my condition?
- How long should I stay in Japan?
- Could the current plan require another trip?
- What follow-up and medical records will I receive after treatment?
Finally
Before paying, check the paperwork rather than the sales pitch. The quote should name the exact treatment and treatment area, show the number of collections and administrations, list included and excluded charges, explain when extra fees may appear, and state the refund rules at each stage. Verify the Japanese regulatory record separately. Add flights, hotels, interpretation and possible extra travel to your own budget. A ¥2.5 million quote is not automatically cheaper than a ¥3 million quote if important services are missing. If the treatment plan changes, get a revised written quote before making another payment.
