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 Japanese law firm with a London office, it can also provide real-time advice on Japanese law to clients in Europe, the Middle East and Africa, and a more convenient service to clients in the Americas.

Our international work, both inward investment and working with our Japanese clients on offshore matters, has expanded very significantly in recent years, with noticeable increases in cross-border anti-trust actions (advising both as lead and local counsel) and high-profile securities litigation in Japan acting for foreign investors.

As a ’foreign law joint enterprise,’ the firm now includes registered foreign lawyers licensed in Japan to advise on the laws of the US states of New York and California, the People’s Republic of China, England and Wales, India, the states of Queensland and Victoria (Australia), US and Australian federal law, and the laws of the Federal Republic of Germany (in collaboration with Janssen Foreign Law Office).
