The simplest kagami-mochi is made of two mochi rice cakes placed on top of each other, with a daidai Japanese bitter orange on top. Since it is made of food, the kagami-mochi is an offering for Toshigami, the kami of the New Year, and it is considered to bring good luck and prosperity in the New Year.
