Personal Data Protection

Stricter protection of personal information has now become a global trend. In a digital society that enables the instantaneous distribution and transfer of large amounts of personal data, protecting the privacy of individuals has become a major issue in Japan as well.

Japan’s Act on the Protection of Personal Information has been constantly updated. In addition, it is necessary to pay attention to the so-called “soft law” established by regulatory authorities, such as guidelines, as well as supplementary rules. We advise global clients with respect to the local requirements including internal rules and systems related to their Japanese businesses, provision of personal data to third parties, cross-border transfers or mandatory reporting of leaks and other incidents.
