This is Jagariko, a snack made by Calbee Corporation. It's a sweet that looks like mashed potatoes fried and crispy. Its crunchy texture is addictive. If you come to Japan, be sure to give it a try. It comes in a variety of flavors, including salad, mentaiko, and cheese. The picture is of Kyushu soy sauce flavor. The price is around 200 yen each.
