Atsumi & Sakai is a multi-award-winning independent full-service Tokyo law firm, and was the first Japanese law firm to create a foreign law joint venture, which permits us to admit as partners attorneys admitted in jurisdictions other than Japan, bringing real international expertise and capabilities to the firm.
Established in 1994 with five lawyers, Atsumi & Sakai now has approximately 120 lawyers (including over 60 partners) and 70 support staff, having doubled in size over the past 10 years. In addition to lawyers admitted in Japan, our firm includes registered foreign lawyers licensed in Japan to advise on the laws of England and Wales, the US States of New York and California, the People’s Republic of China and the States of Queensland and Victoria (Australia) as well as United States and Australian Federal law, and the laws of the Federal Republic of Germany (in collaboration with Janssen Foreign Law Office).
Atsumi & Sakai opened a branch office in London (Atsumi & Sakai Europe Limited) on 23 January 2015. With the opening of A&S Europe, the Firm is able to provide real-time advice on Japanese law to its clients in Europe, the Middle East and Africa. A&S Europe advises on all aspects of Japanese law, with a particular focus on banking, investment funds, project finance, capital markets, securities regulation and M&A, and is able to call on a dedicated team at Atsumi & Sakai, Tokyo for support as needed. The firm also has an office in Frankfurt, established in association with Janssen Foreign Law Office, which advises on German law.
