There is a trend toward international collaboration among quality assurance agencies (QAAs) and the internationalisation of higher education in Japan. This paper is examines how Japan University Accreditation Association (JUAA) can establish a network in the region as it promised to do in the Tokyo Declaration. However, it is very hard for JUAA, a private agency without support from the government, to take the initiative to establish the network based on the agreement of governments such as the Bologna Declaration. In the Asia-Pacific region, JUAA can contribute to networking in a different way by acting as a hub agency and by contributing to developing a common evaluation process and tools instead of common evaluation items and indicators. However, JUAA must not become the only hub agency. Collaboration of some hub agencies will lead to a network among QAAs of many countries in the Asia-Pacific region.
