UNCONSTITUTIONALITY OF RECIPROCITY REQUIREMENT FOR RECOGNITION AND ENFORCEMENT OF FOREIGN JUDGMENTS IN JAPAN

This article deals with reciprocity requirement for recognition of foreign judgments in Japan. Following German law, Japanese law requires reciprocity to the rendering state in addition to the jurisdiction of the state, the service of process, and the compatibility with Japanese public policy. Although Japanese courts have rarely refused the recognition of foreign judgments for lack of reciprocity for a long time, some Chinese judgments recently have not been recognized for this reason. The author clarifies first with historical review what was the purpose of the Japanese legislator, when the original law of 1890 required the reciprocity by international treaties, and when later the reform law of 1926 required the simple reciprocity that is similarly provided in the current law. The author surveys then the Japanese case law concerning the reciprocity requirement after the reform of 1926. The author focuses further on the reciprocity between Japan and China and compares the Japanese practice with the German one that led to a different result. Last, it is concluded that the reciprocity requirement is contrary to the protection of human rights under Japanese constitution.
