One survival story of The Great East Japan Earthquake/Tsunami especially gained worldwide attention: The Kamaishi Miracle. Children at the elementary school in the coastal city of Kamaishi had been dismissed earlier than usual on that day and when the tsunami engulfed the city, teachers watched in despair, believing the water would take them as the kids would have to find safety on their own. But something extraordinary happened: All 184 students survived. The children of Kamaishi knew what to do because they had learned simple rules of survival from the city’s disaster prevention advisor, a university professor Toshitaka Katada. This documentary combines animations and interviews to depict the children’s escape to safety. And it offers lessons on ways to prepare for natural disasters.
