Sompo Auto Insurance

Sompo Auto Insurance is a motor insurance plan from Sompo Japan, available to residents of Japan. Sum insured ranges from varies, eligible ages 18 to 65, and the policy is annual. Below is our take on how it compares to other motor plans in our database — what it does well, where it lags, and the kind of policyholder it actually fits.

Annual premium starts at ¥28K, against a category median of ¥8.5K across the 5 comparable motor plans we track in this country. That places Sompo Auto Insurance in the upper-mid range on price, and the middle of the pack on coverage ceiling (maximum sum insured N/A versus a peer median of N/A). On the value spectrum it reads as priced near the category median.

Coverage is on the leaner side compared to category peers: 0 core inclusions, 3 highlighted features, and 0 optional riders. Notable features called out by Sompo Japan include Comprehensive, 24/7 Claims, and Wide Agent Network.

Motor cover splits into two functionally different things: third-party liability (legally required, capped statutorily) and own-damage cover (optional but the part most people actually claim against). Comprehensive plans like Sompo Auto Insurance bundle both, with the own-damage component priced from the vehicle's Insured Declared Value, year, and city. Premiums quoted publicly are illustrative for a representative profile; expect variation of 30–50% above or below depending on your specific car, location, and claim history. When evaluating motor plans, the two clauses that matter most are the depreciation schedule (how much the insurer deducts from a parts replacement claim) and the cashless garage network — verify that workshops near where you actually drive accept Sompo Japan's authorisation.

Where Sompo Auto Insurance explicitly will not pay: Pre-existing conditions exclusions apply. These are not unusual exclusions for a motor plan, but they are the boundary of the contract — anything outside that list is in scope, anything inside is not. Read the full exclusions list before signing; every plan we have ever audited has at least one exclusion the buyer did not realise was there.
