I brought back 5 flavors recently - strawberry, matcha, orange, and cheesecake. I also picked up the Tokyo banana flavor at NRT while walking through. The rest I got at Don Quijote. I thought the orange and cheesecake were the best, but my nephews and nieces really liked the strawberry and banana. The banana definitely has an artificial flavor, but I guess, in a good way? I also saw strawberry cheesecake at Don Quijote. There's supposed to be a Christmas special Kit Kat with Santa Claus shaped candies, but I didn't find those. There's also supposed to be some new flavors - lemon and one with cacao grown in Japan.
