Aren’t there a lot of Mexicans that would keep the Japanese machine going?
Passing through as a tourist recently it appeared to be a very nice place to live (though merely as a tourist I don’t have the whole picture such as what it would be like to start a business there, pay taxes, etc.). People seemed very polite, honest, and sincerely interesting in providing good service and being helpful.

I have heard this and variations on this for over a decade, but the yen is now very strong (near record-breaking levels, for that matter) and interest rates are still very low.
