Abstract
I observed and analyzed problems that native Japanese speakers (hereinafter referred to as learners) have when listening to lectures in Japanese. The results were as follows: The learners were unable to segment the words and phrases while they were attempting to grasp the meaning of the sentences, and also they could not understand the meaning of the wards and phrases. These problems comprised about 80% of the learner's difficulties. Among native speakers, however, about 23% of the problems were the same. For native speakers, the inability to understand the relation between the words and phrases in the process of analyzing the meaning of the sentences accounted for about half of their difficulties. In my study, I found out that in the process of listening to lectures, both native speakers and learners of Japanese as a second language can experience the same problems.
