It has been pointed out that close ties between universities and graduates are important for donations to universities. However, despite weak university ties in the 1960s, the Waseda University Alumni Association was nevertheless able to achieve the 80th Anniversary Commemorative Project donation target of 2 billion yen. In this paper, we considered the possibility of indirect connections between the university and the alumni association network, specifically with regard to the alumni network born from the micro-movement of University Alumni Association participants. We revealed a structure which focuses on the positional relationship between university faculties and graduates, analyzing the relationship between the structures and graduate donation patterns. With regards to the 1961 Waseda University Alumni Association Meeting, we used affiliation networks, asymptotes, and distance concepts to analyze positional relationships. As a result of these efforts, 4 positional relationships were confirmed: distance of 2, distance of 4, distance of 6, and no path. Furthermore, by focusing our attention on alumni association meetings, we discovered the existence of a distance of 4 (same group) passing through two meetings held in succession by the same alumni association group, and a distance of 4 (different groups) passing through two meetings held by different alumni association groups. Many of the graduates were closely linked. Analysis of the relationship between positional relationships and donation behavior revealed that the closer the distance, the higher the contribution rate, with somewhat obvious results indicating that donor participation and per capita donation rate increase; however, different behaviors were observed for graduates with a distance of 4 (same group). More than half of the graduates located within a distance of 4 (same group) made contributions. However, with respect to amount per donor, donations from members located with a distance of 4 (same group) were the lowest.
