Keiki Heroes is a community empowerment initiative that provides Hawaii’s keiki (children) with fun and engaging ways to encourage habits that keep them healthy and safe.

Our Heroes – Kai and Hōkū

The Keiki Heroes program shares messages through two adorable mascots – Kai and Hōkū – who model positive behaviors like hand-washing, proper mask-wearing, knowing symptoms, and physical distancing.

These adorable characters were created by Yuko Green, a Hawaii Children’s book author and illustrator, and Gum Design.
