This study reviewed the research into the usage of sign language and communication methods through nationwide investigations into the education of the deaf in Japan. It also discussed the significance of that research and future issues. Sign language usage in special needs schools for the deaf started in the 1990s at junior and senior high schools, and in the 2000s at preschools and elementary schools. Since then, sign language has been playing an important role as one of various communication tools. Moreover, most of the research into the sign language was in the form of practical reports from preschools and elementary schools and in teaching Japanese. It is suggested that an accumulation of research on various subjects, especially after junior high school, would be necessary to clarify the effects and challenges of sign language usage in special needs schools for the deaf.
