How to make an insurance claim in Japan
A universal process: evidence, notification, documents, decision, and escalation.
For almost every claim: protect life and prevent further damage, contact the relevant authority, notify the insurer promptly, gather evidence, submit a factual chronology, disclose other cover, obtain the decision in writing, and escalate disputes methodically.
Benefits may vary by: insurer · employment status · municipality · household
Get professional or administrator help: Contact the insurer first, not a paid claim-consultant; for property earthquake claims a municipal certificate is generally not required to file.
