To put it simply, it seems that Fallout is a world where Japan never opened their borders and miniaturization never occurred to electronics. There is absolutely no reference to Japanese anything, and all civilian electronics (and most standard military-grade appliances) are still the boxy, clunky, inefficient hunks of steel and gold that they were like in the 70's.
