This paper presents a case study of the cross-institutional arrangements for Japanese language education between two universities in Canberra, Australia (University of Canberra and The Australian National University), investigating the effects of replacing on-campus course delivery with cross-institutional arrangements. It closely follows the cross-institutional enrolments in Japanese language over three and a half years, and, together with other relevant data, analyses the impact of these arrangements on students' choices. The analyses reveal that the number of Japanese language learners in the region decreased substantially; and the number of University of Canberra students who chose to start Japanese as part of their degrees in decreased to one tenth of the 2016 figure. This paper then discusses potential educational and social impacts of this reduced number of Japanese language learners.
