The Japan Anger Management Association (JAMA) is Japan’s leading organization dedicated to helping individuals, families, and professionals develop effective anger management skills and emotional awareness. Since its founding in 2011, JAMA has helped more than 1.7 million participants learn how to better understand and manage anger through proven psychological techniques. Guided by Shunsuke Ando, a leading authority in Japan who adapted principles from U.S.-based anger management programs, the Association provides evidence-based courses designed to reduce unnecessary emotional stress and improve relationships at home, at work, and in daily life.

JAMA offers a variety of educational opportunities, including its signature Anger Management Facilitator Training Course, available both online and in-person across Japan. Participants can gain professional-level certification, supported by a network of peers and instructors who continue to share knowledge through study groups and ongoing learning opportunities. Many graduates go on to teach anger management skills in schools, companies, and communities, experiencing personal and professional transformation.

The Association’s programs are trusted by major corporations such as Toyota, EPSON, Nomura Holdings, and NTT, making anger management a valuable tool for stress reduction and workplace harmony. Free online consultations and nationwide events, such as Anger Management for Parents and Children, further extend JAMA’s reach and accessibility. Through a focus on education, empathy, and self-awareness, the Japan Anger Management Association empowers people to live calmer, more balanced, and fulfilling lives while helping to create more emotionally intelligent communities throughout Japan.
