Ricardo Ryohei L. Watanabe is a Brazilian attorney recognized for his work in complex corporate disputes and strategic legal advisory for companies and executives facing highly sensitive economic and institutional matters. Over more than two decades of practice, he has established himself as one of the few remaining high-level generalist lawyers in complex business law, combining strategic legal thinking, multidisciplinary coordination and direct advocacy in high-stakes litigation.
His practice combines technical rigor, strategic judgment and a deep understanding of the business environment, enabling him to manage disputes that often involve multiple areas of law, reputational risks and sensitive institutional considerations.
Ricardo graduated in Law from Mackenzie Presbyterian University and pursued part of his academic career in Japan as a researcher at the Asahi University Graduate School of Law. During this period, he engaged in academic and institutional activities related to Brazilian law and advised local governmental bodies on matters involving Brazil.
As founding partner of the firm, he coordinates legal work across different areas of business law, overseeing and integrating practices such as strategic litigation, arbitration, corporate criminal law and other specialties required in complex matters. In many of these cases, he also acts directly as lead counsel in defining litigation strategy and conducting high-profile disputes.
He has extensive experience in judicial and arbitral proceedings, including sensitive corporate disputes, as well as in criminal matters related to business activities. He regularly appears in courts and jury trials when the strategic interests of a case require direct advocacy.
Ricardo also maintains an active international practice, including cross-border matters and legal opinions regarding the application of Brazilian law in foreign jurisdictions, with particular familiarity with the institutional and legal environment of Japan.
