The Japanese can choose from 19 different flavors of Kit Kat, which range from "yubari melon and baked corn from Hokkaido island to green beans and cherries from Tohoku in northeastern Japan to uzu fruit and red potatoes from Kyushu island at the southern-most tip of the country. The Kanto region, including Tokyo, contributed the sweet potato, blueberry and kinako (soybean) flavors."

I'm deferring gross-out until I understand whether or not these Kitto Katsos all contain chocolate mixed with vegetables and miso. . .

I'm still only about 10% of the way through reading this, but it seems like it may be relevant.
