There are no specific rules regarding until what age you should display hagoita and hamayumi.

In the past, they were displayed as "talismans to protect children until they grew up," and it was common to display them until the child reached the age of 15, when they would undergo the "Genpuku" ceremony, which is equivalent to the modern-day "Coming of Age Ceremony."

Even today, some families keep their dolls up until the age of 15, when they reach the age of coming of age, and others keep them up until the age of 18, when they have their Coming of Age Ceremony. Others consider events such as school life and Shichi-Go-San to be turning points in life.

As there is no set time for how long they should be displayed, they are thought of as "charms for the person's growth", and many people continue to display them even after they come of age or get married. They can also be displayed as lucky charms or seasonal decorations.
