To be fair in Japan you have small electronics shops which would shame Radio Shack in it's glory days.

Mostly in Akihabara and maybe some other otaku streets as well, but those small electronics shops aren't all that common in comparison.
There are common 2nd hand stores like HARD-OFF ("hard" as in "hardware" and "off" as in "discounted price", just for context), but that's not a small shop at all.
