Who we are
Atsumi & Sakai is a full-service Tokyo-based law firm; we operate as a foreign law joint venture, which enables us to admit foreign lawyers as partners and so offer our clients a combination of Japanese expertise and real international experience, all with the quality of service that the modern international business community demands.
Building from a base as one of Japan’s leading finance practices, Atsumi & Sakai has expanded rapidly over the last 10 years and now offers a full range of legal services across all business areas through a team of over 200 lawyers, including 23 foreign partners and associates. We pride ourselves on our ability to adapt to developing areas of law and to deal with issues where no precedent exists.
Cross-border work now comprises a significant part of our practice, acting for Japanese companies overseas and foreign companies doing business in Japan. In addition to our Tokyo head-office and Fukuoka affiliate office, we are located in New York, London, and Frankfurt providing quality services effectively around the clock. Most of our Japanese lawyers can conduct business, and draft and negotiate in English, and many have experience of working in the overseas offices of leading global law firms. We also have a team of foreign partners and other lawyers with significant international experience.
*Includes professionals at our offices and affiliate offices and firms within the group, excluding A-PAC INTERNATIONAL LAW FIRM.
**Includes partners and associates who are qualified to practice law (in Japan)
***As of February 2024
As with any large firm with a broad client base, we are occasionally approached to represent clients on cases for which the counterparty is a client we already represent on another matter or with whom we are under contract to provide ongoing legal services, or where there is some other conflict of interest or potential conflict of interest between the parties involved. In order to deal with issues of conflicting interests, our firm has established internal rules and information management systems designed to uncover, investigate and confirm any conflicts or potential conflicts prior to accepting a client mandate, and, where necessary and acceptable, to require measures such as the appropriate allocation of attorneys and other staff and establishing information firewalls so that attorneys and other staff involved in one case cannot access information relating to the other, and otherwise ensuring the protection of clients' interests, and fairness in the performance of our duties as required by the Attorney Act and the Japan Federation of Bar Association's Basic Rules on the Duties of Practicing Attorneys. For further details, please ask the attorneys in charge of your matter.
