Morrison & Foerster has expanded its mergers and acquisitions practice in Tokyo with the hire of highly experienced corporate M&A lawyer Stephen DeCosse from Jones Day. 

DeCosse, most recently of counsel in Jones Day's Tokyo office, joins Morrison & Foerster as a partner. The move actually marks a return to the firm for the veteran lawyer. He was a partner at Morrison & Foerster in Tokyo before leaving in 2006 for Jones Day, where he was also a partner. He moved to of counsel last year.
