The European Interest Group (EIG) CONCERT-Japan is an international joint initiative to support and enhance science, technology and innovation (STI) cooperation between European countries and Japan.

Its primary function is to collaboratively implement multilateral joint funding. As far as it is relevant to that objective, the EIG CONCERT-Japan also aims to facilitate coordination between participating organisations in their activities relating to the programmes of the European Union and those undertaken within other international collaborative frameworks, through the identification of common preferences, priorities and areas of mutual interest.

CONCERT-Japan began as an ERA-NET project from 2011 to 2014. Two successful Joint Calls showed a high relevance of the schemes and the need for continuation. The collaboration is now continuing independently of EU support, as an activity from a broader European Interest Group for Japan (EIG is a flexible platform for communication and coordination among STI instiutions in Europe and Japan).
