Jibaiseki Hoken (Compulsory Automobile Liability Insurance) is required by law for all vehicles in Japan. This basic coverage provides protection for personal injury to third parties but does not cover property damage or the policyholder’s vehicle. The coverage period typically ranges from one to five years and must be maintained throughout vehicle ownership.

How Does Voluntary Insurance Complement Mandatory Coverage?
