Korean or Japanese first?

I totally understand your dillema, I'm also in the process of getting ready to study in Japan in college. However growing up in a military base you inevitably hear stories of Korea, then korean friends, the music and finally a trip to Seoul in relation to Tae kwon do really tempts one. I though made the choice to focus on Japanese. When you're thinking of pursuing two languages especially that can be hard to diffrentiate for an Anglophone I decided since I started Japanese first it would be better to follow through so there's no risk of me confusing any part of it with the Korean language or losing any knowledge I've already gained. You've gotta gauge how well you think you'll be able to pick it up and which is a larger passion for you so no matter how hard at the least you'll be inspired.
