This study applies social realist theory to the analysis of an ongoing online telecollaboration between Japanese undergraduate students in a classroom setting in Japan and Filipino teachers in an English conversation school in Cebu, the Philippines. The accepted goals of telecollaboration in an international context are the development of intercultural communication and linguistic skills. Analysis showed that, without guidance, the influence of Japanese educational policies on students, including a version of internationalisation known as kokusaika, can result in intracultural -- rather than intercultural -- communication. It is suggested that a focus on "small" -- rather than "large" -- culture may help address this issue in Japan, and improve intercultural and linguistic awareness.
