In this study, we used the Rashomon method to interview 8 supporters about the specificities of the language development of the child with ASD and their relationships. The subject child did not produce significant words even during the language acquisition period, but he rapidly acquired language between the ages of 4and 5 years. Interview results reported that the age at which he was able to read varied among interviewees. It was also found that this was influenced by environmental factors. Not only that, the timing of acquisition of “reading” and “speaking” was also seen to be different from that of children with typical development, indicating the uniqueness of language development in children with ASD.
