A misunderstanding then. I just meant the difference between big cities and the rest, similar to Paris/rest of France. The difference you meant was between Spain and Japan. Only 14 km of sea separate our mainland from Africa, with little boats full of desperate people crossing every day. Also we have two towns in continental Africa with land borders with Morocco where border barriers are sometimes just rammed. But that's just the most dramatic side of it. Most immigrants simply cross the borders as tourists and stay for work. I guess Japan is a little different. FWIW, Madrid is very safe at night. Only a few neighborhoods, far from downtown, are dangerous. Edit: immigrant, note taken. Inmigrante in Spanish.
