A Tsujiura Senbei is a Japanese cracker with a written fortune inside.
The cracker is made from unsweetened rice dough.
These are used in Japan at Shinto Shrines at New Year, particularly in Kyoto.
Some people speculate that fortune cookies may have been modelled on Tsujiura Senbei, though unlike fortune cookies, Tsujiura Senbei are not sweet.
A “tsujiura” is a fortune recorded in writing; a “senbei” is a “cracker.”
