Kagami mochi
Kagami mochi (鏡餅, "mirror rice cake") is a traditional Japanese New Year decoration.It usually consists of two round mochi (rice cakes),[1][2][3][4] the smaller placed atop the larger, and a daidai (a Japanese bitter orange) with an attached leaf on top.Sheets of paper called gohei (御幣) folded into lightning shapes similar to those seen on sumo wrestler's belts are also attached.[2] The two mochi discs are variously said to symbolize the going and coming years,[2] the human heart,[2] "yin" and "yang", or the Moon and the Sun.Contemporary kagami mochi are often pre-molded into the shape of stacked disks and sold in plastic packages in the supermarket.
