Yea and you Aussies back home you guys give expats ( 457s ) a warm welcome and lots of love too? Don't get upset when a country actually values locals over foreigners. Japanese are a proud people, and above all they love their country, they support their local industry and products, and thus the "go back to where you came from" treatment, Mr gaijin.
While we're here, why do you call yourselves expats, when back home foreigners are called things like 457s, cheap labour.... Isn't that discrimination?
