Akitas are like people - they are all different! At a year old, your Akita is nowhere near mature, so you don't know what his temperament will be yet. My dog looks on every human as a potential friend, but he does also assess potential "threats" now he's older and more discerning. If he doesn't take any notice of people, that's not a problem, but how is he when people approach you or come to your house? Maybe he's just not a very sociable dog, but I would keep an eye on his attitude, Akitas are not always easy to "read". They are very trainable if you are used to dogs and very firm from the beginning.
He will start cocking his leg anytime in the next 6 months, but they don't do it all the time - they are very lazy dogs!
