Outline of Japan’s Earthquake Insurance System


Outline of the Earthquake Insurance

  • The Earthquake Insurance is an insurance exclusively for earthquake disasters. It indemnifies against damage caused by fire, destruction, burying or washing away, resulting from an earthquake or volcanic eruption or from a tsunami following either of these events.
  • The Earthquake Insurance covers buildings for residential use and household goods.
  • Fire insurance does not indemnify against damage caused by fire resulting from an earthquake or fire damage that spreads because of an earthquake.
  • The Earthquake Insurance is attached to fire insurance. Namely, it is a prerequisite to carry fire insurance in order to carry the Earthquake Insurance. Fire insurance policyholders without the Earthquake Insurance can attach it midway through the policy period.
  • The Earthquake Insurance, whose objective is to stabilize the livelihoods of the affected by earthquakes, is established with the government reinsuring massive earthquake damage which exceeds of certain amount of liability that private insurance companies underwrite.

Reinsurance by the Government

  • For the purpose of stabilizing the livelihoods of the affected by earthquakes, the government reinsures the earthquake insurance liabilities underwritten by private insurance companies. Reinsurance premiums are collected and managed separately in the Special Account for Earthquake Reinsurance. Reinsurance claims are paid out to private insurance companies at the time when massive earthquakes occur.
  • The total amount of reinsurance claims to be paid by the government for a single earthquake, etc. must fall within the limit decided by the Diet every fiscal year.
  • The limit is 11.6586 trillion yen. Combined with the liability sharing for private insurance companies, the limit on total payouts for a single earthquake, etc. sums to 12 trillion yen.
  • The limit on total payouts has always been set at a value that can accommodate massive earthquakes at a level equivalent to that of the Great Kanto Earthquake. The total payouts for past major earthquakes, including the Great Hanshin-Awaji Earthquake and the Great East Japan Earthquake, fell within this limit, enabling the smooth payment of insurance claims.
  • In the case of an earthquake causing damages that exceed the limit, we believe that the government will make every efforts to make timely and appropriate policy decisions, including those for securing financial resources, regardless of the framework of the insurance system, according to the actual conditions of such damages, while also considering other possible measures, such as utilizing the Disaster Victims Livelihood Recovery Support System.

Indemnification under the Earthquake Insurance

  • Buildings for residential use and household goods (movables for daily living).
    The following items are not covered:
    Buildings not used as a residence, including factories and offices; and precious metals, jewels and antiques with values exceeding 300,000 yen per item or per set, currency, securities (checks, share certificates, gift certificates, etc.), deposits and savings certificates, revenue stamps, postage stamps, automobiles, etc.
  • The amount insured under the Earthquake Insurance can be set within a range of between 30% and 50% of those under fire insurance. The amount insured is also limited to 50 million yen for buildings and 10 million yen for household goods.

Payment of insurance claims

  • Under the Earthquake Insurance, insurance claims are paid out when insured buildings or household goods have sustained total loss, large half loss, small half loss or partial loss.

  • Premiums for longer policies
