This presentation offers a succinct update on Japan's dynamic High-Performance Computing (HPC) landscape. The national HPCI framework continues to connect diverse supercomputing resources via SINET6, supporting a wide range of academic and industrial research. Key developments include AIST's ABCI 3.0, a premier AI infrastructure now with 6,128 NVIDIA H200 GPUs, and the pioneering ABCI-Q quantum-AI hybrid platform. The U-Tokyo/U-Tsukuba Miyabi system, featuring NVIDIA GH200 Grace Hopper Superchips, is slated for operation from January 2025. RIKEN R-CCS is advancing a strategy focused on the convergence of HPC, AI, and Quantum computing. The TRIP-AGIS initiative is developing generative AI for science, leveraging "Fugaku" and a new dedicated AI supercomputer. RIKEN is also bolstering its quantum capabilities with new hardware installations, including systems from IBM and Quantinuum, expected to be in production by mid-2025. Looking forward, the FugakuNEXT project aims to deliver effective Zettascale performance for both HPC and AI by the 2029-2030 timeframe, building on a multi-vendor feasibility study. These advancements highlight Japan's strong commitment to pioneering computational science, which will be showcased at SC/HPC Asia 2026 in Osaka.
