This study reports the survey results and the pronunciation practice of Japanese pronunciation teaching in a 15-week intensive program for international students. According to the results, at the beginning of the course the main pronunciation mistakes by Cambodian students were as follows: "tsu" was replaced with "su", "sha" with "cha", "jyo" with "cho" and "su" was often used instead of "tsu" as found in last year's survey. The results from the teaching report and the final check indicate that pronunciation exercises with multinational classmates helped students to be conscious of their pronunciation and improve their pronunciation.
