On June 15, 2018, Japan's Ministry of Economy, Trade and Industry ("METI") issued the Contract Guidance on Utilization of AI and Data ("Guidance"). The Guidance consists of a Data Section and an AI Section. The Data Section covers contracts related to data utilization, and the AI Section covers contracts related to development and utilization of AI-based software. Each section describes the main issues associated with such contracts, provides sample contract clauses, and explains points to be considered in contract drafting. The Guidance may be referred to when drafting contracts related to development or use of AI or data.
