Well, I can say that I've spent more than eleven months learning common characters before learning any Japanese sounds, words, or grammar.
But the reason for that is that I was learning Chinese. I spent zero effort on learning any characters preliminary to that. There is no reason you'd need or want character knowledge.
My character knowledge is decent now, because eventually my learning method became "talk with Chinese people over Wechat", and if you do that you will necessarily learn common characters.
