Due to a coincidence of language, the Kit Kat chocolate bar is enormously popular in Japan.  “Kit Kat” is remarkably similar to the phrase “kitto katsu” (literally: you shall surely win), which is used as a sentiment of good luck.  Students are often given the candy before an exam as a good luck charm.  Unlike the rest of the world, which features only a milk chocolate version, Japan maintains dozens of exotic flavors, such as grilled corn, miso, camembert cheese, baked potato, and soy sauce.
