Sort of.
It started because American doughnut shop bakeries open at like 4 in the morning, and don't close till ridiculous hours, too.
Some were even the only 24 hour shops originally anywhere, serving coffee and pastries at any time.
So we quickly got the cliche of cops sitting at a doughnut shop, or diner counter with coffee and half a dozen doughnuts as they sat around waiting for their patrol to start, or end.
But I personally HAVE seen that translate over to Japanese culture too, there's plenty of anime that make the same trite cop doughnut joke, even for Japanese cops.
But I do wonder if it was the same cultural phenomena for them, or if they're just lifting it from the American culture they consume, and adapting it.

I mean it.
Though, what were you "making" for breakfast originally anyway?
