Misdiagnosis, surgical error, delayed treatment. Bands on this page show typical settlement values for medical negligence cases across the relevant severity tiers; each names its source or is marked as a MyClaimWorth estimate. The position within a band depends on facts the page can't see: severity, prognosis, recovery time, the strength of medical evidence, and any percentage of fault attributed to the claimant under Japan's comparative-fault rule.
