Cross-border M&A, legal due diligence, incorporation of local entities, license support, law research for conducting business, various contracts, corporate governance, labor, overseas infrastructure, project finance, intellectual property rights, dispute resolution procedures (litigation, arbitration), etc.

Since 2011, we have operated an alliance with and continuously seconded Japanese lawyers to A-PAC INTERNATIONAL LAW FIRM (APAC), a law firm in Hanoi with experience in negotiations with Vietnamese government authorities. Through this alliance, we have built up experience of the business environment in Vietnam and been retained by and provided legal services to a large number of clients, mainly Japanese companies that have entered or are considering entering the Vietnamese market.

Our Ho Chi Minh office will be our first in Southeast Asia and our fifth overseas, following New York, London, Frankfurt and Brussels2. It will provide our clients with timely assistance for their business expansion in Vietnam and elsewhere in Southeast Asia and with international projects.

The strength of our Ho Chi Minh office will be to provide timely advice in line with current legal practices through our Japanese lawyers well versed in legal affairs in Vietnam and Southeast Asia and local practices, and a Vietnamese lawyer* experienced in general corporate legal affairs and M&A in Vietnam. We are committed to providing efficient and cost-effective legal services, both outbound and inbound, not only to our clients in Japan but also those in Vietnam, Asia, and the rest of the world.

*Our Vietnamese lawyer does not provide legal advice on Vietnamese law in Japan as she is not registered as a registered foreign lawyer in Japan.

On the opening of the office, it will have two Japanese lawyers and one Vietnamese lawyer, but by utilizing our other offices and our global networks, we will be able to handle large-scale cases both ourselves and in cooperation with law firms in Vietnam and other locations in Asia and globally. We also intend to expand our team in light of our clients’ future needs3.
