Recommended Age
Designed for ages 4–8 (typically preschoolers through second graders), “Kuma the Principal” is especially impactful for children in the 5–6 age range. Through the relationship between the bear principal and the shy sheep, young readers can grasp the story’s message—that every voice, big or small, deserves to be heard.
What the Book Is About
The main character is a friendly bear who serves as the principal of a small elementary school. Every morning, the principal greets students with a booming “Good morning!” that fills the hallway. A timid sheep, who can only speak in a gentle, quiet voice, admires the principal but feels overshadowed by the loud greetings.
One day, the principal falls ill and can no longer speak loudly. Through this change, he learns that “a small voice still has value” and realizes that loudness alone doesn’t measure a person’s feelings or worth. As the principal’s condition forces him to listen more carefully, the little sheep finds the courage to practice speaking up. Ultimately, when the sheep gathers enough bravery to shout “Good morning!” in a loud voice, the principal is deeply moved and understands the power of empathy and encouragement.
Based on the true story of Mr. Satoshi Ōse—who continued teaching his “Life Lesson” classes even after being diagnosed with terminal cancer—this picture book carries a profound message about valuing every moment and every person, regardless of their circumstances.
