The HANAMI project (Hpc AlliaNce for Applications and supercoMputing Innovation: the Europe - Japan collaboration) concluded 2025 with two flagship events aimed at strengthening scientific and technological cooperation between Europe and Japan. Both events took place in Chamonix, France.

The 2nd HANAMI High-Level Symposium (8–11 December 2025) brought together leading European and Japanese experts in climate modelling, materials science, biomedical research, and advanced simulations. Through keynote presentations and panel discussions, participants explored how next-generation High-Performance Computing (HPC) systems can accelerate progress in these strategic scientific areas. Speakers included Xavier Blase (CNRS), Kazuhiro Yabana (University of Tsukuba), Ai Shinobu (University of Osaka), Mario Rüttgers (Inha University), Hirofumi Tomita (RIKEN), and Helene Hewitt (UK Met Office). The symposium aims to foster dialogue, share cutting-edge research, and encourage deeper cooperation between the two regions’ HPC communities.

On 11 December, and co-located with the 2nd High-Level Symposium, the 2nd Europe–Japan Strategic Dialogue gathered policymakers, research funders, and scientific leaders to examine what’s next on the EU-Japan HPC agenda for strategic scientific areas. This high-level meeting focused on future opportunities and sustainability of the collaboration, building on recent progress in strengthening EU–Japan cooperation in HPC. Contributions from policymakers and experts including Kiyoshi Kurihara (MEXT), Rafal Duczmal (EuroHPC JU Governing Board), Pier Luigi Vidale (University of Reading), Ai Shinobu (University of Osaka) and Fabien Grasset (CNRS) supported the development of a shared roadmap for future EU–Japan HPC cooperation.

In addition, the dialogue built on the newly released HANAMI policy paper, “EU–Japan supercomputing collaboration boosts disruptive research and innovation,” which outlines recommendations for sustainable collaboration models, joint funding mechanisms, and shared access to HPC infrastructures. These insights will help inform discussions on advancing EU–Japan HPC collaboration.

Together, these two events reflect the growing ambition and depth of the EU–Japan HPC ecosystem. By bringing together key actors across policy, research, and infrastructure, HANAMI continues to strengthen a collaborative framework that supports scientific excellence and addresses global challenges through HPC area.
