Japan

Long one of the leading litigation firms in Japan, O’Melveny has come to mean even more to its clients. Our Tokyo-based team includes US-licensed lawyers and bengoshi, allowing us to advise multinational and Japanese clients on all facets of Japanese and US law. We are a client’s first call when it faces any dispute involving a Japanese party, including litigation, arbitration, and investigations. And top Japanese corporations turn to us as well, especially for guidance on M&A and private-equity matters.

When it comes to successfully litigating cases in Japan—including before the Supreme Court of Japan (18 favorable judgments)—no other firm can compare to O’Melveny. We are respected and trusted by the judges of Japan, with a series of successes before the Supreme Court in mass consumer litigation brought against various financial institutions and victories in a variety of commercial disputes before the Tokyo High Court and Tokyo District Court.

All the lawyers in our Tokyo office are fluent in Japanese and English, bridging any language or cultural divides. Thanks to decades of international experience—especially in Asia—we are aware of the unique features of cross-border disputes, and we have become skilled at developing resolution strategies for global companies.

Our corporate practice has helped countless Japan-based and multinational companies with cross-border M&A and developing global business strategies. Our Tokyo office is fully integrated with O’Melveny’s global network, enabling us to provide legal solutions and coordinate transactions across geographic and practice lines.

Over four decades, we have earned the confidence of our Japanese clients. The primary goals of the first Tokyo office were ambitious: to preserve and enhance O’Melveny’s practice for Japanese clients and to expand its US representation of Asian clients. Four decades later, O’Melveny continues to fulfill those goals every day.
