In this study, to promote primary psycho-educational services from the school psychology perspective, we conducted and examined the effects of a short-term intervention program to help children recognize and utilize their character strengths. It was found that by recognizing and utilizing their character strengths, many children experienced fulfillment and satisfaction, and their well-being was also improved. Additionally, this program could help children become aware of their character strengths and prepare them to use those strengths in various life scenarios. The present study also explored the possibility of practicing recognition and utilization of character strengths in relation to moral education and special activities conducted in the existing Japanese school education curriculum.
