The Japanese use it as an ingredient for Wagashi associated with the spring season. In the spring, you will see wagashi such as Kusa Mochi (草餅), yomogi mochi (蓬餅), and Hanami Dango 花見団子. It’s also used in a three-tiered diamond-shaped hishimochi, a mochi associated with Girl’s Day/Doll’s Day. You may also see yomogi anpan and other bread offerings at Japanese bakeries. Aside from its use as a natural food dye, it’s enjoyed as a tea, an ingredient in soups and rice dishes, and added to bath water.

There are customs of hanging yomogi and iris leaves outside the home on May 5th to keep evil spirits away. It is said that evil spirits dislike their fresh fragrance, and the herbs could strengthen the body.
