Adding the consultation and blood test brings the listed medical total to ¥1,573,000. Those two upfront charges total ¥33,000, about 2.1% of the ¥1,540,000 administration fee. Travel and any other separately required services are not part of that calculation.
This example is for autologous adipose-derived stem cell treatment for erectile dysfunction (ED). It is not a standard Japanese price for knee treatment or other stem cell therapies. The cost also changes with the cell source. Autologous and allogeneic stem cells involve different collection, processing, and treatment steps.
Cost Breakdown at a Glance
| Cost | How It May Be Charged | What to Check |
|---|---|---|
| First consultation | Included or separate | Does the quote cover the doctor’s first assessment? |
| Blood tests | Included or separate | Which tests are required and will they need repeating? |
| MRI, X-ray, CT, or ultrasound | Often separate | Can recent tests from your home country be used? |
| Fat or bone marrow collection | Included or separate | Are anesthesia and procedure-room charges included? |
| Cell processing | Usually part of cultured-cell treatment | Where are the cells processed? |
| Cell culture | Depends on treatment | Does the fee cover the complete culture process? |
| Quality checks | Usually part of processing | What happens if the final cells cannot be used? |
| Cell transport | Included or separate | Are later shipments charged again? |
| Cell storage | Included or separate | How long is storage covered? |
| Administration | Usually included | Is the price per site, dose, session, or full course? |
| Follow-up | Included or separate | How many visits or tests are covered? |
| Later doses | Usually extra | What is the full planned course price? |
| Interpreter or coordinator | Often separate | Is the service optional or required? |
| Flights and hotel | Usually separate | Will treatment require one Japan trip or two? |
A useful quote should follow the actual stem cell treatment process in Japan: medical review, testing, collection, processing, administration, and follow-up. This makes it easier to see which stage is already paid for and which stage may create another bill.
Costs Before Treatment Starts
The first appointment may change the budget before any cells are collected. The doctor may accept the existing records, request new tests, change the planned treatment site, or decide that treatment should not go ahead.
International patients should send useful medical records before buying non-refundable flights where possible. These may include the confirmed diagnosis, current medicines, recent laboratory tests, imaging, and previous treatment records. The exact requirements vary by treatment. Stem cell therapy indications and contraindications explains why a disease name alone is not enough to decide whether someone is suitable.
Blood testing may be outside the main treatment price. In the ED example, it costs ¥27,500. The same plan includes infection-related screening and allows additional blood testing when medically needed.[2]
- Ask whether recent blood tests from your home country can be used.
- Ask how old your MRI or CT scan can be.
- Confirm whether the clinic needs the original DICOM image files.
- Check whether a later administration will require new blood tests.
- Check what happens to the deposit if testing shows that treatment should not continue.
In this example, the ¥5,500 consultation + ¥27,500 blood test = ¥33,000. The larger financial commitment starts when collection, culture, and administration begin.
Collection and Lab Processing
Autologous treatment uses the patient’s own cells, so tissue usually has to be collected first. Depending on the plan, the source may be fat, bone marrow, blood, or another tissue.
Collection can involve local anesthesia, sterile supplies, the doctor’s procedure fee, blood collection, wound care, and use of the treatment room. If a quote says only “fat collection included,” check whether these related charges are included as well.
The collected tissue may then be sent to a cell-processing facility. Work there can include isolating the required cells, growing them when culture is used, checking the finished preparation, freezing material for later use, and sending cells back to the clinic.
Japan’s Act on the Safety of Regenerative Medicine includes rules for regenerative medicine provision and the manufacture of specified processed cells, including arrangements that use outside cell-processing facilities.[3]
- Where are the cells processed?
- Does the clinic operate the processing facility, or does another company?
- Is the full processing charge already included?
- Who pays if another collection or processing attempt is needed?
A CPC cell-processing center can account for part of the treatment bill because laboratory processing, testing, handling, storage, and traceability all require staff and facilities.
Culture Time and Failed Batches
Not every treatment uses culture-expanded cells. When culture is required, collection and administration may happen weeks apart.
One disclosed ED plan gives an approximately 4-week culture period. A separate knee osteoarthritis plan states that administration takes place about 3–4 weeks after blood and fat collection.[4][5] These are figures from those specific plans, not a fixed timetable for treatment in Japan.
For an overseas patient, that 3–4 week gap can turn one Japan trip into two. A second trip can mean another flight, hotel stay, local transport, and interpreter booking.
Culture charges can cover laboratory staff, materials, cell expansion, preparation, testing, and storage while the cells are being prepared.
The payment terms should also cover what happens when preparation does not go to plan:
- cells grow more slowly than expected;
- too few usable cells are produced;
- culture has to be stopped;
- the finished preparation does not pass the required checks; or
- another tissue collection is needed.
A batch that has been prepared is not automatically suitable for use. Before collection, the clinic should state whether another processing attempt costs extra and what can be refunded. Stem cell therapy safety in Japan explains the wider role of processing and release checks.
Transport and Storage Fees
When processing takes place away from the clinic, tissue and prepared cells may need controlled transport. The ED plan used above includes transport and storage in the main administration fee.[6]
Storage can be charged very differently. One disclosed knee-treatment price sheet lists ¥44,000 including tax every 12 months from the second year onward for continued cell storage.[7]
At that stated rate, 3 renewal periods would cost ¥132,000 and 5 renewal periods would cost ¥220,000, assuming the fee does not change. These are budgeting calculations based on that plan, not standard Japanese storage prices.
- Confirm what material is being stored.
- Check how long the first payment covers.
- Find out when the renewal fee starts.
- Ask what happens if the stored material is never used.
- Check when unused material will be destroyed.
- Ask whether it can be transferred if you change providers.
Per Dose, Per Site, or Full Course?
Dose, session, treatment site, and treatment course do not mean the same thing.
- Dose: the planned amount of cells used at one administration.
- Session: one visit when treatment is given.
- Treatment site: the body area receiving treatment.
- Treatment course: all planned administrations from start to finish.
The ED plan lists ¥1,540,000 for one site and one administration, ¥2,926,000 for two administrations, and ¥4,158,000 for three administrations.[8]
- Going from 1 to 2 administrations adds ¥1,386,000.
- Going from 2 to 3 administrations adds another ¥1,232,000.
Those figures apply only to that ED plan. They do not show what another disease should cost or how many administrations another patient needs.
A knee-specific price sheet gives a different example. It lists treatment with 50 million cells at ¥1,650,000 including tax for one knee and ¥2,200,000 for both knees, including blood testing, fat collection, and transplantation.[9]
Under that plan, treating both knees costs ¥550,000 more than one knee, an increase of about 33%. It does not cost twice as much. That pricing rule belongs only to this plan.
Patients looking at treatment for knee joint disorders should get the number of knees, treatment sites, doses, and sessions written into the quote.
Follow-Up and Repeat Treatment Costs
Follow-up can involve a doctor visit, symptom review, blood tests, imaging, rehabilitation, or checks for side effects. The quote should state how many follow-up visits are included and whether any can be completed remotely after the patient returns home.
Repeat doses should also be priced before the first treatment. One disclosed self-pay plan for chronic musculoskeletal pain lists ¥1,650,000 including tax for the first administration. That price includes consultation, blood testing, and fat-tissue collection. The second and later administrations, using cells expanded from previously frozen material, are listed at ¥1,540,000 each.[10]
The listed repeat dose is ¥110,000 less than the first administration, or about 6.7% lower. That difference applies only to this plan.
The number of administrations should have a medical reason. Before starting, ask whether the full course was planned from the beginning and what would make the doctor recommend another dose.
When Costs Become Non-Refundable
The cancellation stage can change the amount at risk by hundreds of thousands of yen.
The ED plan lists:
| Cancellation Stage | Listed Charge | Amount for the ¥1,540,000 Option |
|---|---|---|
| Before fat collection | ¥33,000 | ¥33,000 |
| After fat collection but before culture starts | 50% of administration fee | ¥770,000 |
| After culture starts | 100% of administration fee | ¥1,540,000 |
These are the terms of that specific treatment plan, not a national cancellation rule.[11]
The possible charge rises from ¥33,000 before collection to ¥770,000 after collection, a difference of ¥737,000. Once culture starts, the listed charge reaches the full ¥1,540,000 administration fee.
Another knee osteoarthritis plan breaks its charges down further:
- first consultation: ¥3,000;
- initial tests: ¥40,000;
- tissue collection: ¥300,000; and
- one-knee treatment using 100 million cells: ¥1,200,000.
If all four items apply, the first-stage total is at least ¥1,543,000 before tax. Consultation, testing, and collection add ¥343,000, or about 28.6%, on top of the ¥1.2 million treatment figure. A repeat consultation, if needed, is listed separately at ¥2,000.[12]
The same document states that the first treatment payment is due by tissue collection and later treatment payments are due three weeks before administration. It also uses staged cancellation rules based on the payment deadline.[13]
The written policy should give separate answers for:
- the patient cancelling;
- the doctor deciding that treatment should stop;
- failed cell preparation;
- a final batch that cannot be used; and
- the provider being unable to deliver the planned treatment.
Also check whether the quote includes Japanese consumption tax. Publicly disclosed treatment documents use both tax-inclusive and before-tax prices.
Costs for Overseas Patients
Patients travelling to Japan may need to budget for:
- medical-record translation;
- medical interpretation;
- international patient coordination;
- international flights;
- hotel stays;
- local transport;
- a companion’s travel;
- extra nights if treatment is delayed; and
- another trip for administration or a later dose.
A culture period of around 3–4 weeks can change the travel plan from 1 international trip to 2. That difference may matter more than a small consultation or testing fee.
Before buying non-refundable tickets, get the expected dates for consultation, testing, collection, administration, and follow-up. The medical travel guide for stem cell treatment in Japan covers the records and timing that should be checked before travel.
Real Japanese Pricing Examples
The figures below come from different treatments. They are useful for comparing billing structures, not for deciding that one treatment is better than another.
| Example | Published Fees | Budget Calculation |
|---|---|---|
| ED, one site | ¥5,500 consultation + ¥27,500 testing + ¥1,540,000 administration | ¥1,573,000 listed medical total before other extras |
| ED, multiple administrations | ¥1,540,000 / ¥2,926,000 / ¥4,158,000 | 2nd administration adds ¥1,386,000; 3rd adds another ¥1,232,000 |
| Knee, 50 million cells | ¥1,650,000 one knee / ¥2,200,000 both knees | Both knees add ¥550,000, about 33% |
| Itemized knee plan | ¥3,000 consultation + ¥40,000 tests + ¥300,000 collection + ¥1,200,000 treatment | At least ¥1,543,000 before tax; the listed extra items add about 28.6% to the ¥1.2m treatment fee |
| Chronic musculoskeletal pain | ¥1,650,000 first administration / ¥1,540,000 later administration | Later listed administration is ¥110,000, or about 6.7%, lower |
| Long-term storage example | ¥44,000 every 12 months from the second year | 3 renewal periods = ¥132,000; 5 = ¥220,000 if the fee stays unchanged |
The underlying fees come from patient information and price documents disclosed through the MHLW e-Regenerative Medicine system.[14][15][16][17][18]
A ¥1.2 million treatment fee, for example, is not directly comparable with a ¥1.65 million package if the first figure excludes consultation, testing, and tissue collection while the second includes them.
Self-Pay, Insurance, and Regulatory Route
Many private regenerative medicine treatments in Japan are self-pay, but not every treatment involving stem cells belongs to the same payment system.
PMDA explains that Japan uses two separate regulatory frameworks here: the Act on the Safety of Regenerative Medicine, which covers regulated regenerative medicine in research and medical practice, and the PMD Act, which regulates regenerative medical products.[19]
A treatment plan disclosed through the MHLW system is not the same as a PMDA-approved regenerative medical product. The Safety Act was also amended, with the revised law taking effect on May 31, 2025.[20]
Japan regenerative medicine registration and compliance explains these two routes in more detail.
Hematopoietic stem cell transplantation for leukemia and other serious blood disorders is another separate area. The Japanese Society for Transplantation and Cellular Therapy states that HLA testing is self-pay at the testing stage and may range from ¥0 to around ¥100,000 depending on the hospital. Transplant-related costs and insurance rules differ from the private regenerative medicine prices discussed above.[21]
Insurance should be checked for the exact treatment, not for “stem cell therapy” as one broad category.

Pricing Red Flags
- “Price from ¥X” with no clear total for the proposed treatment.
- “One treatment” without saying whether it means one dose, one site, or a complete course.
- “Up to 100 million cells” without explaining why that dose is being proposed.
- “Storage included” without stating the storage period or renewal price.
- “No hidden fees” without an itemized written quote.
- A large payment required before important tests or eligibility checks are finished.
- Pressure to pay immediately for a medical discount.
- A claim that more cells or a higher price guarantees a better result.
A provider should be able to explain the treatment, regulatory route, evidence, risks, follow-up, and payment terms without relying on vague package wording. These points also matter when deciding how to choose a stem cell hospital in Japan.
FAQ
Are blood tests included?
Not always. Some plans include them, while others list them separately. In one disclosed ED plan, blood testing costs ¥27,500 outside the main administration fee.
Can I use tests from my home country?
Possibly. The Japanese doctor decides whether the results are recent and suitable. Check the allowed blood-test dates and whether the clinic needs translated reports or original MRI or CT image files.
Can one tissue collection be used for later doses?
Sometimes. Some plans allow intermediate processed cells to be frozen and expanded later. This depends on the protocol and whether enough usable cells can be prepared from the original collection.
What happens if the cells cannot be prepared?
Another collection or processing attempt may be needed, or treatment may stop. The written agreement should state whether repeat processing costs extra and which payments are refundable.
Does one price cover both knees?
Not necessarily. One disclosed plan lists ¥1,650,000 for one knee and ¥2,200,000 for both knees. In that example, adding the second knee increases the price by ¥550,000. Other treatment plans may charge differently.
Will I need two trips to Japan?
Possibly. Some cultured autologous-cell plans leave around three to four weeks between collection and administration. If both procedures cannot fit into one stay, a second flight and hotel stay need to be added.
Does a higher cell count mean better value?
No. Cell number alone does not show that treatment will work better. Diagnosis, cell source, preparation, dose, route, number of administrations, and clinical evidence all matter.
Does a higher price mean better treatment?
No. A higher price may simply include more laboratory work, additional treatment sites, extra doses, storage, or follow-up. Compare what is included before comparing totals.
Finally
The amount that matters is the full treatment-course cost, not the first price shown on a clinic page. In the examples above, a ¥1,540,000 administration becomes ¥1,573,000 after the listed consultation and blood test are added, while a ¥1.2 million knee treatment reaches at least ¥1.543 million before tax after listed consultation, testing, and collection charges. Storage can add ¥44,000 every 12 months from the second year, and cancelling after culture starts can make the full ¥1,540,000 administration fee payable under one disclosed plan. Before paying, confirm the total, treatment sites, number of doses, storage period, tax, refund rules, and number of Japan trips in writing.
