The 1970 Japanese Copyright Act (JCA) basically adheres to the droit d’auteur system. In common with the practice in most civil law countries, it contains a detailed catalogue of specific provisions on the limitations on and exceptions to copyright rather than a general or open-ended clause covering such limitations/exceptions. Over the years, the detailed list of enumerated provisions in the JCA has frequently been revised to adapt to technological development and social change. In fact, a large number of specific copyright limitation provisions were introduced in the 2009 and 2012 JCA, which include specific provisions for web search engines (Article 47sexies), Internet auctions (Article 47bis), text and data mining for commercial or noncommercial purposes (Article 47septies), and experimental exploitations for the purpose of developing technology (Article 30quater). There is no doubt that specific provisions on copyright limitations, and their continual revision, will remain indispensable to copyright law in Japan.
