When evaluating Mitsui Sumitomo against other insurers in Japan, the metrics that matter most depend on the policy you are buying. For term life, claim settlement ratio and financial strength carry the most weight — the policy is worth nothing if the claim is denied at maturity. For health, the network breadth, pre-existing waiting period, and the specific exclusions list matter more than the headline premium difference. For motor, the depreciation schedule and the cashless garage network determine the real economic value of a claim. For travel, the medical evacuation limit and the list of excluded adventure activities are the two clauses to read before buying.
