Facebook is, in most countries, a very popular Social Network Service (SNS). Since the launch of its service in Japan in 2008, it has been growing rapidly. As a platform for a link to the world, Facebook can also be used effectively for language learning in English as a foreign language (EFL) environments. The purpose of this project was to investigate how Facebook can help Japanese university students to improve their English by integrating Facebook activities into English lessons, and examine whether it could facilitate student interaction and self-motivation for learning English. The Facebook project was conducted over the course of one academic year in two parts. A previous study reported on the results of the first semester (????Hamada, 2012). In the second semester, the students were given an opportunity to exchange opinions with American university students. A writing task on Facebook was assigned to both Japanese and American students every week. In this study, I will present the results of the second semester based on a survey and feedback from the students. I will also discuss how the Facebook exchange with the American students can facilitate not only the language learning of the Japanese students, but also the interactions between students and inter-cultural understanding.
