Research Abstract	The purpose of this study was to investigate the nature and treatment of Japanese children with specific language impairment (SLI) by examining the longitudinal data of the two Japanese children with SLI. The results of this longitudinal study demonstrate that while lexical aspects (receptive vocabulary) of language develop rapidly, grammatical aspects (TENSE and PASSIVES) do not in children with SLI. In addition, the results of this study show that such children try to acquire passives by means of compensatory strategies. Therefore it is suggested that the study of compensatory strategies is crucial to the development of the method of treatment for children with SLI.
