Continuing international interest in Japanese culture and critical domestic needs for foreign labor motivate Japanese language learning and testing throughout the world. The Japan Foundation (JF, 2020) recently estimated that over 3.8 million students throughout 134 countries are learning Japanese, largely motivated by interests in Japanese popular culture (e.g., anime), the Japanese language, history, literature, art, employment, study, and tourism. While Japanese society is relatively ethnically and linguistically homogeneous, there are over 3 million foreign residents (about 2.4% of the population) including at least 1.4 million foreign workers ranging from blue-collar workers to medical professionals (Ministry of Health, Labour and Welfare [MHLW], 2019). Japanese higher education is also internationalizing, with nearly 300,000 foreign students enrolled in Japanese universities in 2019 (Japan Student Services Organization [JASSO], 2020). Accordingly, recent estimates suggest there are over 250,000 students in Japanese language programs in Japan (Agency of Cultural Affairs [ACA], 2018).
