How private medical practice works in Japan
Understand what self-pay care means in Japan, why costs differ from country to country, and what to confirm before booking a treatment.
What private practice (自由診療) means
Japan has two categories of medical care: insurance-covered care (保険診療) and private practice (自由診療). Insurance-covered care uses a nationally set fee schedule, and Japanese public health insurance pays a portion of the cost. Private practice operates outside that system — clinics set their own prices, and patients pay the full amount themselves. Most aesthetic treatments, elective surgery, and specialist procedures such as ICL, AGA medication plans, clear aligners, and hair transplant surgery fall into this category.
Why costs vary between clinics
Because private clinics set their own prices, the same procedure can differ significantly in cost from one clinic to another. Factors that affect price include the clinic's location, the experience of the physician, equipment used, the number of staff, included consultations and follow-up visits, language support infrastructure, and the clinic's brand positioning. A lower price does not automatically mean lower quality, and a higher price does not guarantee a better outcome — what matters is understanding what is and is not included.
What Japanese health insurance covers and does not
Japanese public health insurance (国民健康保険 or 健康保険) covers treatments that are medically necessary and listed in the national fee schedule. Elective procedures for cosmetic or quality-of-life goals — such as vision correction surgery, hair loss treatment, orthodontics, and hair transplant — are generally not covered. If you have Japanese health insurance and visit a private clinic, you usually pay the full amount with no insurance reimbursement.
How foreign residents are affected
Foreign residents in Japan who are enrolled in Japanese public health insurance are treated the same as Japanese nationals for insurance-covered care. For private practice, there is no difference — everyone pays the full private fee. Foreign residents without Japanese health insurance should confirm whether the clinic requires proof of insurance for any incidental insurance-covered services that might occur during a private visit (such as an unexpected blood test result requiring further care). Clinics that handle international patients typically have a process for this.
Questions to ask before booking
Ask whether the listed price includes the initial consultation, suitability examination, the procedure itself, all follow-up visits, and any medication or consumables. Ask what happens if you are found unsuitable after paying a deposit or undergoing pre-procedure tests. Ask whether the quote is a fixed price or an estimate, and when the final amount is confirmed. Ask how cancellations and refunds are handled. Clinics that answer these questions clearly before you book are generally more straightforward to deal with.
