In the following decade, the firm opened its Tokyo office, performing M&A and financing work for clients in the region as well as picking up new Japanese, Korean, and Taiwanese clients. Today, Paul Hastings has one of the largest presences in Asia of any US law firm, with offices in Hong Kong, Beijing, and Shanghai, in addition to Tokyo and Seoul.
