Mochi, a traditional Japanese rice cake, has been a mainstay of Japanese culture for thousands of years. Their association with New Year celebrations as The Tale of Genji, the first novel in history.

These days, mochi pounding (or mochitsuki) is mostly ceremonial. Electronic mochi makers are as rice cookers. The Nara Prefecture in southern Japan is the traditional home to mochitsuki masters, but if you can't get there, you can slap your rice cooker very quickly at home for similar results.
