This document provides an overview of RIKEN, an institute for basic research in Japan, and its Advanced Institute for Computational Science (AICS) located in Kobe. It discusses RIKEN's facilities, budget, and centers across Japan. It then describes AICS in more detail, including its computer and research buildings. The document outlines Japan's FLAGSHIP2020 Project which involves developing the next-generation supercomputer called Post-K working with Fujitsu, as well as developing applications in priority science areas like healthcare, disaster prevention, and energy. It provides high-level details on Post-K's planned ARM-based architecture and software stack.
