Some 3 billion fortune cookies are made each year, almost all in the United States. But the crisp cookies wrapped around enigmatic sayings have spread around the world. They are served in Chinese restaurants in Britain, Mexico, Italy, France and elsewhere. In India, they taste more like butter cookies. A surprisingly high number of winning tickets in Brazil's national lottery in 2004 were traced to lucky numbers from fortune cookies distributed by a Chinese restaurant chain called Chinatown.

But there is one place where fortune cookies are conspicuously absent: China.

Now a researcher in Japan believes she can explain the disconnect, which has long perplexed American tourists in China. Fortune cookies, Yasuko Nakamachi says, are almost certainly originally from Japan.

Her prime pieces of evidence are the generations-old small family bakeries making obscure fortune cookie-shaped crackers by hand near a temple outside Kyoto. She has also turned up many references to the cookies in Japanese literature and history, including an 1878 image of a man making them in a bakery - decades before the first reports of American fortune cookies.

The idea that fortune cookies come from Japan is counterintuitive, to say the least. "I am surprised," said Derrick Wong, the vice president of the largest fortune cookie manufacturer in the world, Wonton Food, based in Brooklyn. “People see it and think of it as a Chinese food dessert, not a Japanese food dessert,” he said. But, he conceded, “The weakest part of the Chinese menu is dessert.”
