Japan is such an amazing country. I want to see it all. But, if I have to choose one, I'll go for Kagoshima because a penpal I've been exchanging letters for some time lives there and he really made me want to go there.
Here, where I live, there is nothing like that to buy so I never really tried japanese snacks but I definitely would like to. Pocky first comes to my mind (obviously). And, it's not really a snack but I really wanted to try melon soda for a long time now.
Hmm...I'll go with Younha and her Te wo Tsunaide.
