Japanese rice cakes are made from sticky glutinous rice(mochi rice) steamed and pounded until it becomes smooth. Mochi is made from glutinous rice, which is different from the "Uruchi rice" that Japanese people regularly eat for rice. In the mochi making, they pound the sticky rice with steaming hot and then finish ponding; they hurriedly form it into the desired shape. Mochi becomes hard when it cools down and can be stored. Freshly made soft rice cakes are enjoyed, seasoned with bean paste, soy sauce, or soybean flour mixed with sugar.

Mochi is an essential food for celebrations, not only at New Year's but also at various festivals and annual events. Neighbors and relatives are used to gather to pound mochi and share the rice cakes during festivities and ceremonies. Mochi comes in different shapes and flavors and is eaten for seasonal celebrations.

The name "Arare" also means "hail" in Japanese).


At Kagami-biraki(Ceremony of "Opening" Kagami-mochi), people eat rice cakes, which are believed to be inhabited by the gods, to share their power and wish good luck and good health for the year. "Cutting" Kagami-mochi with a knife is considered bad luck because it reminds us of "seppuku," the act of a samurai committing suicide in disgrace. So they started to use a wooden mallet to break them into small pieces and started using the word "Opening" instead. Since the Edo period, this samurai-style has spread to the general public and has taken root. In reality, you have to "break" the dry and hardened Kagami-mochi as shown in the photo, but the word "break" also has a negative feeling, so people began to say "open" to describe as th
