Navigating the Japanese Healthcare System
-
Referral Letters (Sensaisho): To see a specialist at these top university hospitals, you usually need a referral letter from a smaller local clinic. Without one, you will likely be charged an extra “first-visit fee” (around ¥5,000–¥10,000).
-
JCI & JMIP: Look for hospitals with JCI (Joint Commission International) or JMIP (Japan Medical Education Foundation) accreditation. These institutions are specifically equipped to handle international patients.
-
National Health Insurance: Almost all these hospitals (except for specific private cosmetic clinics) accept Japan’s National Health Insurance, which covers 70% of costs.
