Kusa mochi (草餅)

Kusa mochi (草餅)

What is Kusa mochi?

Kusa mochi ​​(草餅) is one of the Japanese sweets also known as “kusamochi or yomogi mochi (蓬餅).” Locals made it using mochi and yomogi (known as Japanese mugwort) leaves. In fact, this Kusa Mochi is the Yomogi Mochi kneaded with Japanese mugwort leaves from the Shinshu region around Nagano Prefecture. Kusa mochi is a vibrant green color due to the use of Japanese mugwort in the mochi.

The amount of Japanese mugwort in the mochi determines how green it is. Japanese also used this as a medical diet. It is a rice cake mixed with boiled mugwort leaves and they sometimes fill the rice cakes with bean paste. It is a common and often homemade treat for young and old alike. When the grass and trees begin to sprout their spring colors, many Japanese heads for the mountains or rivers to enjoy the abundance of wildflowers and plants, one of which they used to make Kusamochi.


Kusa mochi (草餅)

Today’s Kusa Mochi is from wormwood or yomogi, but they originally made this using “Ogata (御形)” which means mother and child herbs. Both Kusa mochi and Yomogi ochi uses wormwood. And so in the name of the Japanese confection “Kusa Mochi (草もち)”, “Kusa (草)” means “grass” or “herb” in Japanese which comes from the eaves of Yomogi or the Japanese wormwood. While “Mochi (もち or 餅)” refers to a glutinous rice cake. So the green color of the sweet treat comes from mixing yomogi or wormwood with the rice cake.

Kusa mochi History

Kusa mochi (草餅)

Documents state that nobles were eating kusa mochi during palace events in the Heian era. They made it with Jersey cudweed before the Heian era. However, since the Heian era, people started to make kusa mochi using Japanese mugwort (or yomogi) because of its capability to boost fertility and as a medicinal food. 

Another purported reason for the change in ingredients was because they called the Jersey cudweed Haha-ko-gusa which translates to “mother-and-child grass”. As they enjoyed kusa mochi to wish for the health and well-being of the mother and her children, locals considered it ominous to knead jersey cudweed into the mochi. Since the Edo-era, kusamochi began to be used as an offering for Hinamatsuri (the Girl’s Festival) because of the vivid green color that represents fresh verdure. Another reason why is because of the medicinal power of Japanese mugwort. Japanese mugwort is known for its vitality, which makes it difficult to eradicate.
