Facebook has become a worldwide phenomenon and is currently the most popular social networking service by worldwide active users. Being so widely used, its potential for use in intercultural exchanges is promising. However, as yet there is little discussion of how Facebook can best be used in an intercultural exchange. A valuable feature of Facebook is the ability to create a Facebook Group where instructors have control of membership, and where activities designed to encourage language learning and greater cultural awareness can be implemented. This paper will describe and evaluate an intercultural exchange between university students in Japan and Indonesia that took place during 2011. The exchange was found to be beneficial because students were able to learn about another culture while improving their English.
