A&S Osaka was established in Osaka, Japan's second city and second largest economic hub, in 2025, to service the growing demand from domestic and international businesses for diversified and sophisticated legal services in the Kansai region and surrounding area; with this office our network now comprises eight offices and affiliate offices in Japan and overseas. From its Tokyo base and other offices, domestic and international, Atsumi & Sakai provides its clients with high-level expertise in a broad range of legal and business fields including cross-border transactions, M&A, finance, intellectual property, risk management, and commercial disputes. Focusing on corporate law, A&S Osaka plays a key role in enabling us to provide enhanced support to companies and foreign-affiliated businesses in the region.
Japanese lawyers and registered foreign lawyers at our other offices work in partnership with A&S Osaka as necessary and provide timely and precise solutions to the legal needs of clients in the Kansai region. The office actively supports local companies expanding overseas and foreign companies entering Japan, as well as providing legal advice to regional financial institutions and venture companies.
As a full-service law firm that combines a global outlook with responsiveness tailored to local needs, A&S Osaka and Atsumi & Sakai are committed to providing legal services of the highest standard to our clients.
We look forward to assisting clients in the Kansai region, as well as in the adjacent Chubu, Chugoku and Shikoku regions, so please do not hesitate to contact us.
