This article is based on a Cross-Cultural Distance Learning (CCDL) model between university students in Korea and Japan during the 1st semester of 2016 and this lesson model consists of synchronous and asynchronous CMC activities focusing on the interactions between non-native speakers of English. This article shows that EFL learners in Korea can develop English language proficiency through this lesson model. The learners' development of English language proficiency was evaluated by using the TOEIC test as a proficiency test form. Also, this article proves that these kinds of CMC activities can motivate EFL learners to enhance cultural awareness for foreign countries and practice English inside and outside of the classroom. The questionnaire was used to survey the students' cultural awareness and attitude for this model at the final session of the semester.
