Japanese Law A-Z

Japanese Law-Related Resources by Topic or Type (A-Z)

In general, court decisions are harder to locate than laws. English translations of court decisions are rare, but some are available (see below).

Cases are not indexed by party names, and often party names are removed from case reports because of privacy issues. Instead, court decisions are indexed by the court, the date, and also by the citation to the statute at issue in the case. Docket numbers (see below) are unique identifiers for cases in Japan's single national court system, which is administered by the Supreme Court. Keyword searching allows access by the full text of cases, and is available in all commercially available online Japanese legal information systems. These include Westlaw Japan, available with a UW NetID to University of Washington users. Other similar online services include LexisNexisJP, LEX/DB Internet, and D1-Law.com.
