This study was conducted for the following two purposes: 1) to create and test a process by which cultural information in English textbooks in Japan can be analyzed, and 2) to examine what and how much information about foreign culture is taught in English classes in Japan. First, a process was developed from Joiner's evaluation form to gauge the cultural content of EFL textbooks. Action was taken to ensure that the process included both qualitative and quantitative steps. Second, the process entailed an analysis of the cultural content of 10 senior high school English textbooks published in Japan. The process was found to be functional and the analysis revealed that the textbooks were inadequate for the purpose of raising students' cultural awareness. The results of this study may be utilized not only for the improvement of textbooks, but also for future studies which might examine junior high school and college English textbooks. / Education, Faculty of / Language and Literacy Education (LLED), Department of / Graduate
