When I was in Canada for a wedding earlier this month, my friend from Tokyo told me he and his wife were going into town to buy special edition burned coffee-flavored Kit Kats. Sampling different flavored Kit Kats has become a side hobby for some Japanese, and in turn Nestle produces unusual flavors for consumption — mostly in Japan, but also in other countries, presumably for Japanese tourists to take home as gifts. Some of the more curious flavors include soy sauce, grilled potato, and sports drink.
