Japan has a civil-law system built mainly around written legislation. The Constitution is the highest legal rule and protects basic rights while defining the roles of government institutions. The National Diet makes statutes, and the Cabinet and ministries issue more detailed rules within their legal authority. Prefectures and municipalities can also adopt ordinances for local matters. Japan has several major fields of law. They include constitutional, administrative, civil, commercial, labor, immigration, family, and criminal law. Courts form a national hierarchy, with the Supreme Court at the top. Lower courts include high courts, district courts, family courts, and summary courts, each with different responsibilities. Many ordinary legal matters begin outside court. A person may first contact a municipal office, ministry bureau, police station, labor office, consumer center, or another authority responsible for the issue. Documents are especially important in Japanese legal and administrative practice. Contracts, notices, receipts, application forms, residence records, and written messages can show what happened and when. Disputes may be handled through negotiation, mediation, administrative review, or litigation. The suitable path depends on the subject, urgency, available evidence, and remedy sought. The system offers formal rights and organized procedures, but language, cost, time, and unfamiliar paperwork can limit access. Early advice from the correct public office or a qualified Japanese professional can prevent avoidable mistakes.
