Tao Co., Ltd. (Kusatsu, Shiga Prefecture; CEO: Yoshiaki Kurosawa), developer of the tablet-based learning material Tenjin, which turns the home into a preschool classroom, added the Japanese nursery rhyme “Amefuri” to the preschool tablet version of Tenjin on May 12, 2026. The addition is intended to help children in overseas families with Japanese roots inherit the Japanese language and culture. As children become more accustomed to local environments, Japanese can gradually disappear from daily life. According to Japan’s Ministry of Foreign Affairs, the number of Japanese permanent residents overseas increased by about 27% from 2015 to 2024. Meanwhile, the Ministry of Education, Culture, Sports, Science and Technology reports that the number of students enrolled in Japanese schools overseas fell by about 22% during the same period. These figures point to a broader social challenge: passing on Japanese language and culture to the next generation growing up abroad is becoming increasingly unstable. In Japan, children naturally hear Japanese at home and in daily life. Overseas, that is not always the case. Language is part of a child’s identity. As global talent becomes increasingly important, more children may lose touch with their roots without realizing it if they grow up without understanding Japanese language and culture. Parents using Tenjin while raising children overseas share a strong desire to expose their children to Japanese. Tenjin is currently used by families in more than 35 countries and regions. As children adapt to local languages and cultures, Japanese can be left behind. This is a pressing concern faced by many parents raising children abroad. Japanese nursery rhymes convey not only words, but also seasonal imagery, rhythm, and emotional nuance unique to the Japanese language. Through singing, children encounter Japanese and absorb elements of Japanese culture. “Amefuri” depicts a rainy-day scene and is filled with Japanese words and rhythms. By s
