Lozenge-shaped (diamond-shaped) rice cakes, usually consisting of three distinct colored layers (sanshoku means "three colors"), derived from an idea in ancient philosophy that these colors were protection against evil and danger. The topmost, pink (aka) layer resembles the peach blossoms that chase evil spirits away. The middle, white (shiro) layer symbolizes snow and purity. The bottom, green (ao) layer represents health. The cakes are offered to the ministers on the fourth tier, and sometimes to the three ladies-in-waiting on the second tier. |
