Exotic KitKat flavors have become so popular in Japan that Nestlé, which manufactures the candy bars, is getting a brand new factory dedicated to making them.
The wafer chocolates have been available in more than 300 flavors such as green tea and wasabi. Those flavors, Nestlé told the BBC, have helped KitKat sales in Japan grow by 50 percent since 2010.
The new factory will focus its efforts on developing more expensive versions of the popular treat, which has become a hit among tourists.
"We take pride in our unique flavors and I think that makes Japan special in the KitKat world," Takuya Hiramatsu, a spokesman for Nestle Japan, told Bloomberg. He added that the matcha flavor, along with wasabi, sake and purple yam are a favorite for tourists.
KitKat may have gained noteriety in the United Kingdom when the chocolates debuted in 1935, but as Bloomberg explains, the product's name may have contributed to its dedicated consumer base in Japan. That's because, the product's name sounds a lot like "kitto katsu," or "sure win" in Japanese.
