The impact of culture on language has been acknowledged for many years (Vygotsky, 1962) as well as how local culture may influence the communication strategies and interactions of EFL learners. Since intercultural communicative competence is the key to such communication, I investigated the perceptions of Japanese university students of integrating American and British cultural activities with language learning both in and outside of the EFL classroom. Data were collected through a questionnaire administered to 78 university students. The results suggest that students had positive attitudes and an interest in developing further understanding of the target language culture both in and outside of class. Furthermore, they believed that the target language culture should be incorporated in the teaching of foreign languages. Therefore, this study highlights the need for integrating the teaching of culture with language instruction into the curriculum in the Japanese context.
