This begs the question, how do you give directions in Japan if the streets have no names?

Raises, not begs. "Begging the question" refers to avoiding an answer. "Raising the question" refers to bringing some related question to mind.

Sorry to nitpick, but that particular error really bothers me for some reason.

Since we're nitpicking, that's not what begging the question refers to. Begging the question is assuming the proposition. If I asked you why all rottweilers are bloodthirsty then I'd be begging the question because I've implied that all rottweilers being bloodthirsty is established fact.

Assuming the proposition can also be done by restating the premise of a question as the answer. An example from WP:
Person A: He is really mad right now.
Person B: How do you know?
Person A: Well, because he's really angry.

I had to go check, and it would appear that you're correct. My apologies. So now we have four things we can do with questions: raising, begging, avoiding, and (rarely) answering. You just gotta love the English language, no?

Raising is still the proper term here, though.

Nitpicking aside, how do you give directions in Japan?

Explained, briefly, in the video. The reality of finding an address involves getting a hand-drawn map (which drove the innovation of the fax machine) and stopping to get directions from a police box which of necessity is placed on just about every block in large cities. So, confusing city planning promotes information technology and urban safety.

While some (many? most?) streets in Japan don't have names, many do. That might be a relatively new thing, but I usually navigated around using the streets whose names I knew. Or maybe the streets were just named after the blocks they abutted/connected? I don't know, but there were highway numbers and street signs and streets labeled on maps. Names of streets did change more frequently as you went along them than they do here, though.
