Japanese fortune cookie
A traditional Japanese cracker with a fortune slip inside, associated with New Year's and 辻占 (fortune-telling at crossroads).
We eat tsujiura senbei at New Year's to tell our fortunes.
Paper fortune slips drawn at shrines and temples, not a food item.
The Western fortune cookie, which is a different food with a similar concept.
From 辻占 (tsujiura, 'crossroads fortune-telling') + 煎餅 (senbei, 'rice cracker'). The exact historical origin is uncertain, but it is a traditional sweet associated with New Year's fortune-telling customs.
