This chapter discusses Japanese perspectives on the Hague Principles. Japan belongs to the civil law system, although some legal institutions grounded in common law also exist. At the end of the nineteenth century, Japan transplanted Western legal systems. Along with the codification of the Civil Code and other statutes, the Private International Law Act, Hôrei, was adopted in 1898, which was modernized and substituted by the Japanese Act on General Rules for Application of Laws (AGRAL) in 2006. The AGRAL designates, out of several conflicting laws, the law which has the closest connection with the legal relationship concerned. This value-neutral, multilateral method consists in localizing the legal relationship in a certain jurisdiction, grounded on the equality and interchangeability of domestic law and foreign law. While the judge does not have the authority to directly apply the Hague Principles instead of the AGRAL in litigation, the judge can certainly refer to the Hague Principles in seeking guidance for interpretation or filling gaps of the AGRAL, same as for other international, regional, or domestic conflicts rules, including the relevant Hague Conventions.
