As of October 2019, there were 124 international students enrolled at the University of Aizu and only one Japanese language teacher. Under the government's policy of actively hiring foreign human resources, support for foreign students in job hunting is attracting attention in line with the cooperation of related ministries and agencies. In a span of 10 months at this computer science university, the following issues were observed: underutilization of Japanese language classes, lack of recruitment opportunities, and problems with meeting students' needs. Various solutions are explored in order to better facilitate international science students' Japanese language learning and job hunting in Japan.
