Good Child Day (Yoiko no Hi)

What Is Good Child Day?

Every year on April 15th, Japan observes "Good Child Day" (Yoiko no Hi). The date comes from the wordplay "yo (4) - i (1) - ko (5)," which sounds like "yoiko," meaning "good child." The organization that established it is unclear, but it is introduced as a day to wish for children's healthy growth and to deepen communication between parents, children, and the community, at a time when the new school year has just begun and children are working hard to adjust to new environments. Rather than defining "good child" by what's convenient for adults, it's a day to find and affirm each child's unique strengths.

Other Days with the Same Wordplay

Because 4-1-5 can be read as "yoiko," several other observances share this date.

• IJIMEQUEST415 Day: Established by VAPORCELEB Inc., which launched a project to end bullying, and registered with the Japan Anniversary Association in 2019. It is a day to cheer on "good kids" who don't bully and don't give in to bullying, and to think about bullying.
• Good Yeast Day: Established by a company that handles yeast products, from the wordplay "yo (4) - i (1) - ko (5) - ubo" (good yeast).

How the Idea of a "Good Child" Has Changed

• From obedient to independent: In the past, a "good child" often meant one who did what adults said; today, having your own opinions and respecting differences in others are also valued.
• The role of adults: Children grow freely when they feel safe even when they fail. Not only families but also adults in the community can provide that support.

Fascinating Facts About Children

• "The soul of a three-year-old lasts to a hundred": This Japanese proverb means that the character formed in early childhood lasts a lifetime. Here "mitsugo" means a three-year-old child, not triplets.
• "Shitsuke" is a Japanese-made kanji: The character 躾 (shitsuke, upbringing/discipline), combining "body" (身) and "beautiful" (美), was created in Japan. It is said to convey the idea of making one's conduct beautiful.
• Leonardo da Vinci's birthday: April 15th is also Leonardo da Vinci's birthday.
• Not Children's Day: Japan's national holiday "Children's Day" is May 5th, defined by law as a day to respect children's personalities, promote their happiness, and thank mothers.

Tips for Spending Good Child Day

• Find three specific good qualities in a child close to you and put them into words — notice their effort, not just the results.
• Try something new together with a child. Be surprised together and laugh off mistakes side by side.
• Pay attention to children's safety in your community: check the school route for dangerous spots and exchange greetings.
• At work, find something good about a new colleague or junior and tell them.

A Day to Notice What's Good in Children
