Update: took my car to the dealer, replicated the noise with one of their tech's in the car and had the car in the shop for 2 days.
Today I picked up my car and the factory rep happened to be there and took a look at my car yesterday. He said that the noise is normal because they use straight cut gears rather than angled gears which tends to produce more noise. the guy said that the noise may go away with additional miles...
I also started looking through the forums in Japan and it seems like they have the same issues and can't do anything about it either.
I also tried searching around for straight vs angle gears and it seems the trade offs for straight over angle is more efficient gears but more noise and less durability.
Long story short, I guess we're stuck with the noise for the time being...
