KitKat Yuzu kitkat: There's a small KitKat shop in Ginza. I'm not sure if it's the main one because I've seen more KitKats in a room in most malls here, but they did have them individually packaged in nice collector cases. They were pretty pricey, a $3 for a single KitKat (not even the type you break in two, which I thought was a defining characteristic given the jingle but apparently not in Japan). I purchased the most interesting looking one: Yuzu. It's actually very good: sour and tart, like a lemon flavored yogurt with a little orange flavor too. The chocolate coating is a pale orange color. AOtherwise, familiar KitKat texture. Definitely worth trying! 4.0/5.0
