A&S Fukuoka LPC was established in 2022 to provide efficient and effective legal services to clients in rapidly developing Fukuoka, leveraging the extensive networks Atsumi & Sakai has cultivated in Tokyo and overseas.

Collaborating with experienced lawyers from our affiliate firm, Atsumi & Sakai Legal Professional Corporation, our services cover the full spectrum of corporate law matters, ranging from startup support, transaction agreements, financial regulations, domestic investments and loans, cross-border investments, mergers, M&A transactions, multidisciplinary advice specialized in the agriculture, forestry and fisheries industries, IPOs, fund formation, and dealings with regulatory authorities (including applications for licenses, permits and approvals) to labor matters, IP rights, dispute proceedings including litigation and arbitration, and overseas expansion support. Our services in the aforementioned fields are available both in Japanese and English, and based on the requirements of any given case, we have the option of collaborating with the lawyers and registered foreign lawyers of our partner Atsumi & Sakai LPC in Tokyo as needed.

While lawyers are often associated with handling court cases, confirmation of legal aspects is necessary even for regular transaction agreements. We are highly flexible and can bring our services to where you need them, so please don't hesitate to contact us.
