Takoyaki is a Japanese snack that is in the shape of little round balls. It is made with a batter that has a wheat flour base and is commonly filled with minced octopus, scraps of tempura, green onions, and pickled ginger. It is usually served with a sauce that is similar to Worcestershire sauce and mayonnaise.

The creation of Takoyaki dates back to 1935 and its creation is credited to a street vendor named Tomekichi Endo.  It quickly became popular in the Kansai region of Japan and then it spread to other areas as well.  Today, Takoyaki can be found in many areas of Japan being sold by street vendors, and in specialty restaurants, and it can even be found in supermarkets and convenience stores.
