I am one of English language teachers who is working in my native country which is situated in south east asia. I have been working here as an English language teacher for about 10 years. I have already got some certificates concerned with Teaching English as a second language teacher. However, what I want to know is: is it possible for teachers like me to get a job as an English language teacher at Japan for elementary levels?
