Frequently Asked Questions
Can I get insurance for diabetes in Japan?
Yes, but options vary. Some international insurers will cover diabetes as a pre-existing condition (often with higher premiums or waiting periods). Others may exclude it. BUPA Global, Cigna Global, and Allianz Care are known for being more accepting of pre-existing conditions. Always disclose your condition fully—non-disclosure can void your policy.
Will my medications be available in Japan?
Most common medications for diabetes are available in Japan, though brand names often differ. Bring your prescriptions with generic (international) drug names. For the first few months, bring a supply from your home country while you establish local care and verify medication equivalents.
How do I find a doctor for diabetes in Japan?
Start with your insurance provider's network directory. Expat Facebook groups and forums are excellent for personal recommendations. International hospitals typically have English-speaking specialists. You can also ask your home country doctor for referrals to colleagues in Japan.
What if I have an emergency related to diabetes?
Know the local emergency number and location of the nearest hospital with appropriate facilities. Keep a medical information card with your condition, medications, and emergency contacts. Most international health insurance includes 24/7 emergency assistance—save this number in your phone.
Should I disclose my diabetes when applying for insurance?
Absolutely yes. Non-disclosure is considered fraud and can result in your entire policy being voided when you need it most. Insurers can access international medical records. Full disclosure may mean higher premiums or exclusions, but you'll have clarity on what's covered and valid coverage when you need it.
