We, the Computational Particle Physics (CPP) Workshop Organizing Committee, is proud to announce the 4th CPP Workshop scheduled to take place in October 2016 in Japan. In the past we have hosted the series of CPP Workshops in 1998, 2001 and 2010, respectively and successfully, covering the following areas of study; higher-order radiative corrections, automatic computations in the quantum field theory, numerical methods in the particle physics, and other related topics in the high-energy physics. As you might have already heard that Professor Yoshimitsu Shimizu, the principal organizer of these Workshops, passed away last October. We intend the coming Workshop to partly be a memorial meeting for him and cherish wonderful and precious moments we shared with him. We welcome you to make a presentation for either the scientific or memorial session during the Workshop. The workshop will take place between the evening of Saturday, 8 October, and the afternoon of Tuesday, 11 October 2016, in Hayama where Prof. Shimizu spent his last years. We all hope that you will join us at this Workshop and share your thoughts with us throughout the event. Toshiaki KANEKO The Chair of the 4th CPP Organizing Committee Last Update: Apr 16, 2016
