Throughout the entire negotiations, the European Commission furnished regular reports to the national governments of the EU Member States, the European Parliament, and to civil society organisations. Documents that were made available to the German government were automatically passed on to the German Bundestag as well. German MPs were able to access these documents at any time.

The European Commission also published additional information pertaining to the negotiations on its website, which can be accessed here (in German). This information includes reports about the individual negotiation rounds and the original text of EU proposals. The texts which the EU and Japan have agreed upon as part of their political agreement were published immediately after the agreement was reached. They can be found here. In addition, the European Commission published the negotiating mandate on 14 September 2017.
