in my opinion : i would learn speaking because when we like to learn a language we should consider our selves like child who learn his navite language for the first time ,,, then he learn writing ,,,,

Ohayo gozaimasu... You start learning "hiragana"then some basic vocabulary... I guess speaking is the first step for learning any language ...memorize some dialogues ...such as greeting ...and some important expressions ...when you start speaking that will give you some self confident ...... don't give up ..Japanese is not for lazy persons ..hard work is waiting for you ...good luck

ideally you would learn both together. you probably won't get to Kanji until later, but you can learn the alphabet first, that way you can recognize each symbol and the sound it makes.
