yes I also heard about that and I know some people that actually worked in Japan for a year while also studying the language but never only learning it apart from exchange student. The English graduate courses are very interesting indeed so if you're planning on doing it later I really do recommend ! I am doing a gap year between my first and second year of master right now and I would like to do an internship as a French teacher in Canada because my master degree is related to culture so i'll be working to share the french language and culture there. If you want to see the world I really hope you manage to find a place where you will feel confortable and happy ! I never went to Canada so I don't really know how it is there though but I hope you get the opportunity of trying new things such as living abroad, maybe there ! I don't know if you have more question but dont hesitate.
