Atsumi & Sakai is a multi-award-winning, independent Tokyo law firm, and one of the ten largest independent full-service law firms in Japan. The firm was the first Japanese law firm to create a foreign law joint venture, which enables it to admit foreign partners and so offer its clients the quality of service that the modern international business community demands. Expanding from its highly regarded finance practice, the firm now acts for a wide range of international and domestic companies, banks, financial institutions and other businesses, offering a comprehensive range of legal expertise.
Atsumi & Sakai has an outward-looking approach to its international practice, and has several foreign partners and consultants with extensive experience from leading international law firms, so providing its clients with the benefit of both Japanese law expertise and real international experience. As the only independent Japanese law firm with a London office, it can also provide real-time advice on Japanese law to its clients in Europe, the Middle East and Africa, as well as providing a more convenient service to its clients in the Americas. The firm’s international work, both inward investment and working with its Japanese clients on offshore matters, has expanded very significantly in recent years, with noticeable increases in cross-border antitrust actions (advising both as lead and local counsel), both domestic and overseas projects and PFI transactions including renewable energy and infrastructure, and high-profile securities litigation in Japan acting for foreign investors.
As a ’foreign law joint enterprise,’ in addition to lawyers admitted in Japan (including a Japanese lawyer also admitted in England and Wales), the firm includes foreign lawyers registered in Japan to advise on the laws of the US States of New York and California, the People’s Republic of China, India, the State of Queensland, Australia, US and Australian Federal laws, and the laws of the Federal Republic of Germany (in collaboration with Janssen Foreign Law Office).
A broad, international network of contacts and many years’ experience working closely with other leading law firms across the globe enables Atsumi & Sakai to assist clients in the selection of overseas counsel and to provide them with tailored advice on cross-border transactions in collaboration with closely connected offshore lawyers.
Innovation & Diversity:
The firm constantly seeks to anticipate its clients’ needs for new legal services, most recently those arising from the rapid technological developments in the financial services industry, and strives to provide high-quality and cost-effective services and solutions to support start-up companies. The firm also offers a flexible alternative fee arrangement tailored to meet the specific needs and goals of each client company. Atsumi & Sakai takes a proactive approach to diversity, with nearly 30% of all lawyers being women and 10% foreigners, and encourages its lawyers to maintain a good work/life balance, which has seen the firm recognised as Japan’s leading law firm for employee satisfaction.
