Wataru Sueyoshi


For approximately 37 years, Wataru Sueyoshi has handled general corporate law and intellectual property matters in addition to representing clients in a wide range of litigation. He has been involved in a number of complex and precedent-setting cases, including the WSJ Copyright Infringement Case (Tokyo High Ct. Oct. 27, 1994), the IFN Patent Infringement Case (Tokyo High Ct.

After receiving an LL.B. from the University of Tokyo in 1981, Wataru joined Mori Sogo (currently, Mori Hamada & Matsumoto) in 1983. Before Wataru’s joint establishment of Sueyoshi & Sato in 2020, he and some of his colleagues left Mori Hamada & Matsumoto to establish STW & Partners (currently, SHIOMIZAKA) in 2007. The numerous articles and books he has written have been published in recognized journals and by distinguished publishers.
