I've always been facinated with products you can't easily find in the U.S. - especially those that come from Japan. Where as, in America, we'll have Coke, then variants like Cherry Coke, Vanilla Coke, Coke with Lime and so on. In Japan, they will have Kit-Kat, then flavors like sweet potato, wasabi and blueberry cheesecake. Most are very good, but even those odd ones are fun.
Not too much surprises me about Japanese snack products anymore until I saw these. Pepsi flavored Cheetos.
