Kenji Yamamoto primarily handles corporate legal affairs and labor law issues. The central questions he seeks to answer in representing clients have always been, “How can corporations pursue justice?”, and, “What are the true interests of the client?” Mr. Yamamoto has a great deal of experience in representing corporate clients in claims for damages made by claimant groups, and in the course of the pursuit of justice, he has come to believe that corporations must fulfill their social responsibilities appropriately. Based thereon, he has been dealing with many cases and has been providing advice relating to corporate governance, including assisting outside directors in business judgment decisions, as well as implementation of compliance measures, etc. Moreover, he has been actively involved in legal professional training by serving as a specially appointed law school professor.
