The purpose of this study is to consider the causes of language acquisition delay in JSL (Japanese as a Second Language) children studying Japanese as a second language from the perspective of their willingness to learn. The results confirmed that as Japanese language instruction advances, children tend to lose motivation to study. Specifically, willingness to learn is highest when lessons begin and decline rapidly around the time teaching the 50 syllables finishes, and by the end of the lessons it was clear motivation was almost entirely lost.
