In this study, the current state of JSL students with delayed second language acquisition was analyzed, and a variety of support was attempted using picture books and audio material in addition to paper Japanese texts. The result was a confirmation that the support for Japanese learning and Japanese input at home were nearly zero. It was also noted that there was an effect on understanding and fixing of vocabulary, and motivation maintenance from using audio and visual tools in addition to text, when compared to text only.
