As far back as the 19th century, a cookie very similar in appearance to the American Fortune cookie was made in Kyoto, Japan, and there is a Japanese temple tradition of random fortunes, called omikuji. The Japanese version of the cookie differs in several ways: they are a little bit larger, are made of darker dough, and their batter contains sesame and miso rather than vanilla and butter. They contain a fortune, however, the small slip of paper was wedged into the bend of the cookie rather than placed inside the hollow portion. This kind of cookies are called Tsujiura Senbei and still be sold at some regions in Japan. Most of the people who claim to have introduced the cookie to the United States are Japanese, so the theory is that these bakers were modifying a cookie design which they were aware of from their days in Japan.
