Japan gets all the cool Kit Kats. Since 2000, Nestlé has introduced over 200 flavors and varieties of the chocolate bar to Japan, from chestnut and espresso to baked corn and soy sauce.
Some flavors come and go with the seasons and others are exclusive to certain regions; at the souvenir shops of my home prefecture Nagano you can find the tasty Shinshu Apple flavor and the questionable Ichimi Ground Red Pepper flavor.
One of our Japanese reporters recently came across a new variety of Kit Kat at Nagoya Station that we thought was pretty cool. While the Kit Kat bars themselves are the regular milk chocolate flavor—which, mind you, differs from country to country—the box art is inspired by the Tokaido Shinkansen line and should be familiar to anyone who has ridden the bullet train in Japan.
