Hughes Hubbard & Reed has hired counsel Paul Marston to serve as the firm’s Tokyo office head, making up for the departure of arbitration counsel Tony Andriotis, who was the firm’s sole lawyer in the Japanese capital.

Marston came from Pillsbury Winthrop Shaw Pittman, where he also was counsel. He focuses on corporate and finance matters, particularly on project development and mergers and acquisitions, in the energy, construction, pharmaceuticals and technology industries. Last year, he was part of the Pillsbury team that advised Japanese conglomerate SoftBank Group Corp. on a $77.7 million investment in Canadian lithium miner Nemaska Lithium Inc.
