The 2026 Hackathon on Interoperability of Digital Public Infrastructure invites innovators to Tokyo to advance the EU-Japan Digital Partnership and the G7 Data Free Flow with Trust (DFFT) framework. Building on the success of the Bengaluru edition, this event challenges cross-regional teams from the EU, Japan, and the Indo-Pacific to develop seamless, regulatory-compliant prototypes that bridge the European Digital Identity (EUDI) framework with Japan’s digital identity ecosystem and other foundational systems like MOSIP. Participants will gain exclusive access to a managed dataspace testbed pre-configured with Gaia-X and NGSI-LD connectors, allowing them to focus on solving complex cross-border identity and data sovereignty challenges. 

Final pitches are scheduled to commence in Tokyo on Thursday, 26 March, at 12:30 JST, where each team will deliver a 6-minute presentation followed by a 5-minute Q&A session. The jury will then evaluate the solutions based on strict success criteria—including EUDI integration and cross-border verification—and innovation potential to select the top teams. Winners chosen during this process will be awarded the opportunity to present at the final INPACE event in Brussels in 2027.
