For nearly three decades, O’Melveny’s team in Tokyo has been helping clients achieve their business goals. From Japan’s westward drive in the 1980s, to our representation of the world’s leading technology companies in their mergers and acquisitions in Japan, we have handled landmark cases and significant deals, both inbound and outbound, for a wide range of clients.

Our team includes US-licensed lawyers and bengoshi (licensed Japanese lawyers), allowing us to advise multinational and Japanese clients on virtually all facets of Japanese and US law. Our Tokyo office is fully integrated with O’Melveny’s global network to provide legal solutions that cross geographic and practice lines. All of our lawyers are fluent in Japanese and English, bridging language and cultural divides.

Whether the undertaking is a cross-border acquisition or a complex international arbitration or multijurisdictional litigation matter, our team in Tokyo gives clients an edge in the competitive global marketplace.
