Japan has a sweet romance with KitKat. Yes, I mean the KitKat bars that tells you to have a break. It's those two-fingered bars that you eat by breaking it smoothly in half.
Before coming to Japan, I only knew of the ordinary Chocolate-flavored KitKat wrapped in red. Then boom! I went to Tokyo and discovered strawberry KitKat. I started living in Hamamatsu and saw green tea (macha) KitKat. When I went to Kyoto, yatsuhashi KitKat was there. Then there's apple-flavored KitKat in Nagano and sweet bean KitKat in Takayama. There's pumpkin KitKat during Halloween and sakura (cherry blossom) KitKat in spring. Suddenly, my knowledge of KitKat grew just like that.
