J-List is a great place to find the newest and coolest stuff from Japan. But you can also find the oldest stuff, including the traditional candy of the Showa Period, called dagashi. From classic Sakuma Drops (as seen in Grave of the Fireflies) to the new Kyoto-style traditional candy and awesome Kompeito, J-List has a huge selection for you to browse. One candy that's fun is neri ame or "kneading candy" which is a liquid candy you mix with chopsticks for several minutes, until it becomes firm enough to eat. Best of all, these traditional candies are very inexpensive, so you can get a great sampling for $20 or so.
