This is a spring wagashi. Its name is hibiscus pancake, and its Japanese name is ひしもち. It has three colors: red, white, and green. It is usually placed in a Hina doll display on Hinamatsuri Festival (March 3) as a display and placed on the bottom floor. Can also be eaten alone.

Although the three colors of red, white and green are the most common, there are also two, five or seven colors due to regional differences. The current shape was finalized during the Edo period.

The red cake symbolizes respecting ancestors and eliminating evil. Because it uses the fruit of gardenia, which has detoxifying effect, it also means blessing health like peach blossoms. The white cake is filled with water chestnuts, which have the effect of lowering blood pressure, and the clean surface also symbolizes residual snow. The green cake was originally made from motherwort (ハハコグサ, also known as motherwort), which has the effect of nourishing blood. It symbolizes the grass sprouting in early spring. The rhombus shape symbolizes the earth.

To put it simply, the color of the lozenge cake, red represents "elimination of disasters", white represents "purity", and green represents "health and vitality". Therefore, eating water chestnut cakes on Daughter's Day means that parents hope that their daughters can "grow up healthily and happily without any disease or disaster."
