This study reaches the following conclusions. (1) The number of Japanese language learners worldwide, including in Japan, is increasing. However, the number of Japanese language learners varies by country, and the phenomenon of imbalance is still obvious. (2) The issue of Japanese education for foreigners in Japan deserves more attention. Attention should also be paid to the fact that the education and experience of Japanese teachers in various institutions in Japan are not uniform. (3) The Japanese government seems to pay more attention to Japanese education in Japan than to Japanese education abroad, and Japanese budgets for Japanese education are unevenly distributed. (4) The number of Japanese language learners in Taiwan has decreased significantly in recent years, and the problem appears to be in institutions of higher education.
