In 1988, Allen & Overy was one of the first international law firms to establish an office in Tokyo. For over 30 years, the Allen & Overy Tokyo office has provided comprehensive legal services to a wide range of corporate clients (both domestic and international), banks, financial institutions, trading companies and energy companies.

The Tokyo practice specializes in the following major areas: Corporate and M&A, Projects, Energy, Natural Resources and Infrastructure (PENRI) and Banking & Finance.

Our longstanding history in this market, combined with our extensive network of offices worldwide, with both international and Japanese law capability and bilingual lawyers, means we are often the first port of call for companies seeking assistance, whether it be on their inbound or outbound transactions.
