Asanoha is a hexagonal geometric pattern that resembles the leaves of the hemp plant (asanoha), hence the name asanoha.

Asanoha motif was used in the kimono costume of kabuki actors during the Edo period, and it became popular among young women around the same time.

There was the custom of wrapping a newborn baby in the baby kimono with asanoha motif, because asa was known for its rapid growth and sturdiness.
