And despite the vagaries of life in their new country, most of the foreigners in Japan are living better lives than they would have back home. That's certainly true of the Brazilians in Homigaoka.
I did a research paper on Nikkei Brazilians and according to all the info I came across that's not true. Most of them are well educated and middle or upper middle class. They often had a higher standard of living back home but the value of the yen versus the real makes it worth their while to put up with rougher living conditions.
Of course a semi literate high school drop out born in Japan might have it pretty tough if his family were to return to Brazil.
