The sustainability of universities has become a pressing concern worldwide, particularly in Japan, where the declining 18-year-old population has led to a significant decrease in university applicants. This paper argues that to enhance the sustainability of universities, it is essential to incorporate a “realistic perspective” of “advanced management” alongside the pursuit of educational ideals. Drawing on the principles of Eduinformatics and the UNESCO learning analytics framework, we propose a collaborative approach that leverages the expertise of external partners, such as education companies, to support the resolution of common management issues faced by multiple universities from a macro perspective. By fostering collaboration between faculty and staff, optimizing workflows, and engaging in strategic decision-making, universities can navigate the complexities of the modern educational landscape and develop innovative solutions to sustainability challenges. Our findings underscore the importance of embracing a multi-level perspective that integrates the micro, meso, and macro levels of learning analytics, with a particular emphasis on the macro level. We argue that by partnering with education companies, universities can benefit from their management expertise and gain valuable insights into emerging trends and best practices, ultimately contributing to the long-term sustainability of higher education institutions in the face of unprecedented challenges.
