Norio Kimura, who lost his wife and father in the 2011 Great East Japan Earthquake and Tsunami Disaster and whose 7-year-old daughter, Yuna, remained missing until a bone fragment was found nearly six years later due to nuclear zone restrictions, now channels his grief and anger into disaster awareness. He emphasises the preciousness of family and everyday life, urging others to learn from the tragedy to prevent future sadness. Although Yuna would have been reaching adulthood this year, her legacy lies in her father's ongoing crusade to instill the vital lessons of the disaster in others.
