Just an afterthought when in the check-out line at the famous Economy Candy store (in business 80 years!) and it turned out to be really good! I don’t remember if I’ve had the American version, so I can’t compare, but the chocolate tasted like American chocolate, so it was familiar. Since Nestle, a Swiss company, owns it, that may account for a certain consistency all over the world. Perhaps some of the American chocolate I am thinking of actually originates in Switzerland. This is getting complicated, so I’ll stop here!* *10/24/18: I think this article in the New York Times answers my questions & may be of interest to all you Kit Kat lovers & general food lovers: https://www.nytimes.com/interactive/2018/10/24/magazine/candy-kit-kat-japan.html
