Study on the World Law at the interwar period in Japan

有一种标准的观点认为，世界法作为一门社会科学的研究始于二战后的日本。然而，在两次世界大战期间有一些重要的作品。特别是在20世纪30年代初，二战后出任国际法院法官的田中光太郎出版了臭名昭著的《世界法论》一书。与此同时，作为日本第一位法律的哲学教授，常藤京也发表了一些关于世界法的经济和社会思考的文章。因此，他在两次世界大战之间建立了以社会科学为基础的新的世界法理论。

There is a standard view that the study on the world law as a social science started after world war second in Japan. However, there were significant works at the interwar period. Especially at the early 1930's, Tanaka kotaro, who became the judge of international court of justice after world war second, published the notorious books named "The theory of World Law". At the same time, Tsuneto kyo who was a first professor of legal philosophy in Japan published some articles on the world law related to the economic and social considerations. In consequence, he formulated new theory relating to the world law based on social science at the interwar period.
