The purpose of this present study is to investigate the task types found in five Monbu-kagaku-sho approved textbooks for Oral Communication I, which are currently used in senior high schools and national colleges of technology. In order to enhance students' ability to express their thoughts or opinions, it is important that the tasks are designed using authentic and communicative activities. Two viewpoints are applied to analyze the tasks: four levels of communicative activities and three aspects of self-expression scales. The obtained results of the analysis show that the number of authentic and meaningful tasks is relatively sufficient, respectively from half to all the tasks in the textbooks, but that the tasks to provoke students' self-expression and creativity are in the development stage in terms of quality and quantity.
