AI model advancement demands cross-enterprise data collaboration, but strict privacy regulations create barriers. This session explores a commercialized Data Clean Room in Japan by Acompany and KDDI, a Fortune Global 500 telecom company. We will share the architecture enabling secure data matching and privacy-preserving AI development. We detail how this satisfies the strict third-party data transfer restrictions under Japan's Act on the Protection of Personal Information (APPI). By keeping the calculation process protected, enterprises can jointly analyze sensitive large-scale datasets—including personal and location data—without exposing raw information to partners. Furthermore, we explore the relationship between policy discussions and CC in Japan. With CC recognized as an essential data security technology in public and private sectors, we discuss the potential for market expansion. We provide insights into how bridging governance and technology creates a scalable confidential AI infrastructure.
