When people who know go to Tokyo, they buy one souvenir. Make that, the best souvenir. They buy Tokyo Banana. And that snack just got better because it's getting a Kit Kat version.

Of course they do. Japan is famous for interesting Kit Kat flavours, and this latest one might be the most unusual one yet.

This week in Tokyo, you can buy Kit Kat sushi. Dreams are real!

Making Japanese Kit Kats sure seems fun. Checking them, though, that looks hard, especially when thousands of them are rolling by every minute.
