As of today, Japan is officially associated to Horizon Europe. Home to 123 million people, Japan is the most populous country associated to the programme, adding one of the world's most advanced research and innovation ecosystems to Europe's network of scientific cooperation.

The agreement allows Japanese researchers and organisations to take part in Horizon Europe on equal terms with those from EU Member States and other associated countries. They will be able to join and lead international research consortia, receive EU funding, and work alongside top research institutions to help address global challenges.
