EUSI (EU Studies Institute in Tokyo) is a centre where the three Tokyo universities - Hitotsubashi University, Tsuda College, and, a new member, Keio University - collaborate on education, research and outreach activities on EU related issues. It was launched on April 1, 2009 and succeeds the EUIJ (EU Institute in Japan). It will promote the activities under the sponsorship of the European Commission from the 2009 through 2012.

Tsuda College will develop a wide variety of EUSI activities, as parts of its education, research and international exchange programmes.

Two Joint Research Groups, 'Law and Politics' and 'Economics', will engage in EUSI research activities. Tsuda College, based on its experience with the previous programme 'International relations reviewed from the regional perspectives', intends to utilize its international networks in order to make a new contribution to the research and education activities of the consortium.
