Atsumi & Sakai is a multi-award-winning, independent Tokyo law firm, and among the largest independent full-service law firms in Japan. The firm was the first domestic 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.

"I’m very satisfied, its work is fast and professional and the cost is reasonable. It has helped us prepare purchase and lease agreements; it has helped us with regulatory matters and applications; and it has also supported our negotiations. They are lawyers of course, but they are commercially aware and have good experience that we benefit from."
