The United States didn't declare war because they were still hoping to be able to stay out of the war. Japan didn't declare war because their strategy was to cripple the US Pacific Fleet, and they figured that would be easier to do if the US wasn't expecting it.
As it worked out, they didn't cripple the fleet, they just (in the words of Spike Jones) made the Yankees cranky, which ultimately didn't work out well for them. It's certainly arguable that the sneak attack made it easier for the US to demonize the Japanese, and that that in turn made it easier to contemplate using atomic bombs against Japan (though it's also arguable that the real cost of civilian lives and property damage was less than it would have been in a conventional invasion, so maybe it did work out well for them after all).
They were trying to figure out a way to give the USA the declaration of war only moments before the attack so that the surprise would not be outside of the rules of war. They failed in this regard and the declaration of war was provided to Washington over three hours after the attack began.
There was no declaration before the attack on Pearl Harbor because the Japanese government believed a surprise attack would cripple the United States Pacific Fleet and prevent them from interfering with Japanese military expansion in the Asia-Pacific region. It was seen as a strategic move to gain an advantage in the early stages of the war.

I am afraid you are confused. The Declaration of Independence was signed BEFORE the war. It resulted in the war. That is why it is called the Declaration of Independence the colonists declared themselves free of England.
