Anderson Mori & Tomotsune, one of Tokyo’s Big Four corporate law firms, has announced plans to open offices in Singapore and Shanghai this year, pending regulatory approvals.

The planned expansion by the 317-lawyer firm is the latest in a series of similar overseas moves by Japanese firms in recent years. Another Big Four firm, Nagashima Ohno & Tsunematsu, opened a Singapore office at the beginning of the year. The other two, Mori Hamada & Matsumoto and Nishimura & Asahi, opened Singapore offices in 2012.
