I've shown many of the local Kit Kat flavors that you can find in Japan, but other snacks come in local flavors
Next to the Collon is Hi-Chew, a soft Starburst-like candy (but better!). That's yubari melon (sweet cantaloupe) flavored. So is the Pocky next to it. On the right is a fish flavored Pretz. Pretz, if you didn't guess, is a stick pretzel snack, though it tends to come in flavors, and isn't buttered or salted like normal pretzels are.
The big yellow bag is a chip-like crunchy snack, but I don't remember what it is, and the red bear package must have had a cookie or something. The blue packages at the bottom are "soft katsugun" candies, though it's been a little too long and I don't recall their flavor.
But then there's also the potato-shaped Hokkaido Ageimo. And yes, it has a potato flavor. And everything here was quite tasty.
