I don't know if you are in Japan, but if so, all you have to do is walk around and hundreds of help wanted signs. I never saw a foreigner work at a 7-11 store but the other day I saw 2 working at the store. This was in Matsuyama, Shikoku. I thought to myself, why would they come to Japan just to work for a convenience store . I don't have an answer for that.
