"Smiley House" opened in August 2010 for moms and dads who want to teach their children the joy of physical activity, want to participate in lessons with their parents, and want a place where they can take a break from raising their children. Ayako Murata, who is also a representative and instructor, specializes in dance at university and has a wealth of experience teaching children. We propose lessons such as baby dance and baby cheer that make parents and children smile.
