Squire Patton Boggs merges with Tokyo corporate boutique

Squire Patton Boggs has completed its first bolt-on since the merger of Squire Sanders and Patton Boggs, taking on three-partner Tokyo firm Mamiya Law Offices.

The deal, which went live over the weekend, brings Squire Patton Boggs’ Tokyo lawyer headcount to just under 40.

Founded in 2008, Mamiya Law Offices is led by partner Jun Mamiya, who was previously a partner at Addleshaw Goddard alliance firm Hashidate Law Offices and Atsumi & Partners (now Atsumi & Sakai). He and his fellow partners remain partners at Squire Patton Boggs and bring with them a senior associate and an associate.

Mamiya, whose practice focuses on domestic and international corporate work, said he was attracted to Squire Patton Boggs because the firm has offices “in countries where our clients seek to do business”.

“As part of a global practice we’ll now be able to offer clients considerable added value and leverage our presence to support our clients on significant international projects,” he added.

The merger of Squire Sanders and Patton Boggs, which was sealed at the beginning of June (27 May 2014), created a 1,700-lawyer firm with 45 offices across 22 countries. The bulk of that coverage came from the Squire Sanders side of the deal; that firm had around 1,300 lawyers spread across 39 offices.   

Squire Patton Boggs’ Tokyo managing partner Ken Kurosu said he first worked with Mamiya 20 years ago, adding that the two firms shared a number of “major public institutional clients”.
