Japanese civil law provides rules for relationships between private persons and organizations. Its central legislation is the Civil Code, called Minpō, together with other laws for business, housing, family, and specialized matters. Contract law concerns agreements such as sales, services, loans, leases, and employment-related promises. A contract may sometimes exist without a formal signed document, although written proof makes its terms easier to establish. Property law deals with ownership, possession, use, and security rights. Registration is especially important for some rights, including interests connected with land and buildings. Civil liability can arise when a person unlawfully causes harm to another. A claim commonly requires careful examination of conduct, fault, causation, loss, and any available defenses. Family law covers matters such as marriage, divorce, parent-child relationships, and support. Family courts play a major role in mediation and decisions when family members cannot agree. Inheritance law determines how property, obligations, wills, and heirs are handled after death. Family registers, called koseki, and other official records can be important for proving family relationships. Civil disputes may be handled through negotiation, mediation, civil conciliation, family-court procedures, or litigation. A favorable judgment may still require a separate enforcement process if the losing party does not comply voluntarily. Civil law offers ways to enforce agreements and repair private harm, but evidence, cost, time, and collectability matter in practice. Early organization helps a person choose a realistic remedy rather than pursuing a claim blindly.
