The team at Atsumi & Sakai, which is headed by the 'highly qualified' Saori Hanada , handles a vast range of international matters, including private enforcement in foreign jurisdictions, internal audits, merger control cases, and international cartel cases. Other work the practice undertakes includes risk management advice, investigations by authorities, and advice on vertical restraints. Masayuki Matsuura is a key contact for merger cases, while the 'outstanding' Tatsuo Yamashima is a name to note for cartel investigations. Setsuko Yufu is recommended for her deep knowledge of cartels, bid rigging, and leniency.
