1. Background

The National Policy on Promoting Open Access to Publicly Funded Scholarly Publications and Scientific Data’ (Provisional translation) was created by the Integrated Innovation Strategy Promotion Council on February 16, 2024. In it, the government states that in order to enable everyone to access to scholarly publications and scientific data freely, it promotes supporting the establishment of a collective bargaining system of universities to negotiate with global academic publishers (‘platformers’) and aims to optimize the financial burden on the research community through these negotiation efforts. Since strong negotiating power is necessary to achieve this, the Cabinet Office organized a meeting, whose members were vice presidents and directors of the universities consisting of RU11 (Research University 11), a consortium of Japan’s leading research universities. At the meeting, in preparation for the start of discussions with academic publishers regarding contract terms, the Cabinet Office requested universities to cooperate with one another and team up to build a collective bargaining system, which led to the establishment of OASE. The team consisted of a number of experts on issues related to academic journals. Members worked together in their respective roles and collaborated with JUSTICE, which has proven expertise and experience in negotiation, to promote open access through consultation with global academic publishers.
Subsequently, further discussions were held at a meeting organized by the Cabinet Office, with universities and academic research institutions interested in Transformative Agreements for scholarly journals participating as members. It was decided that the team would transition to OASE+ in December 2025. OASE+ inherits the activities of OASE and operates as a joint initiative between JUSTICE and OASE.
