This study reports the survey results of Japanese Pronunciation Teaching in a 15-week intensive program for international students. The results showed that Cambodian students found it difficult to distinguish between "tsu" and "su", "shi" and "chi", "ji" and "chi", unvoiced and voiced consonants, and double consonants and that Vietnamese students found it difficult to distinguish between "tsuu" and "chuu", "zo" and "jyo", "ne" and "e", and unvoiced and voiced consonants. The results from the questionnaire indicate that students can become conscious of their pronunciation, and its improvement, after pronunciation exercises are practiced for at least 10 minutes a day.
