Kagamimochi

Kagamimochi is a smaller round rice cake placed on a larger one on a stand called sambo.
It's decorated with a Daidai (橙/bitter orange), Kobu (昆布/kelp), Ise-ebi (伊勢海老/lobster),
Hoshigaki (干し柿/dried persimon), Urajiro (裏白/Gleichenia japonica) Yuzuriha (楪/Daphniphyllum macropodum)
and other bringers of good luck.

Daidai	橙/Daidai is the same sound with 代々/daidai which means generationafter generation. So, a bitter orange is symbolized a wish to be gifted with children.
Kobu	Kobu is asociated with yorokobu which means becoming happy
Ise-ebi	Lobster's back is bent. It's a simbol of long life.
Hoshigaki	Ten dried persimons are skewered two for each side and six in the center.(photo below) This is the symbol of good couple. Itsumo nikoniko(means "smile" and sound is the same with two and two) naka (center) mutsumajiku (six)....Always smiling and on good terms.
Urajiro	New leaves grow with old leaves. So, it is a symbol of long life. It also a symbol of pure heart beacuse it's back is white.
Uzuriha	Old leaves bend down their head when a tree put forth leaves, but they never fall down. In the following year, when they put the third generation buds, they start to fall down. So, yuzuriha is symbolized a wish to have a family like this.
