OK. Let me begin.
You seem to think you know what you are talking about with reference to immigration to Japan, however it is nothing more than second hand information that you have received from 'friends' who are 'GOING' to Japan, not becoming Japanese citizens. This could be from years of sitting in front of a computer screen, being an online casanova or even worse, an online know-it-all about topics in which you personally have no experience. Such as if I was to suddenly tell everyone on here that watching pornography will cause cancer because I heard it from some guy who was talking to his friends at a bar in Turkey while I passed by his table to go wash my hands.
So ... there you go.
(Hey, you told us to find out things about you using years of sociology and psychology classes, I did)
