Digital Synergies: Bulgaria–Japan Dialogue on Digital Twins, AI, Data Spaces & Urban Futures

Join Us for an Exclusive Bulgaria–Japan Innovation Dialogue! 

Date and Venue  / Program Day1, Day2 / Registration  

Outlines: 

In the spirit of strengthened bilateral cooperation between Bulgaria and Japan, these two interconnected events convene leading voices from government, academia, and industry to explore shared opportunities at the intersection of Digital Twins, Artificial Intelligence, Big Data, and Data Spaces. 

The events build upon the positive momentum of the Joint Statement on the Establishment of Strategic Partnership between the Republic of Bulgaria and Japan, signed on 20th May 2025 in Tokyo by President of Bulgaria Rumen Radev and Prime Minister of Japan Shigeru Ishiba. This high-level agreement highlights a mutual commitment to deepen digital cooperation and celebrates the strategic academic partnership between the GATE Institute (Bulgaria) and the Center for Computational Sciences (CCS), University of Tsukuba (Japan), as a key pillar of this vision. 

Together, the two-day programme will strengthen institutional ties, promote co-creation, and advance collaborative agendas for sustainable, digital, and resilient urban futures.
