The story of the 47 Ronin is a real historical account of Japan. Its author wanted to reinstate in the modern times that there is more to human life than the repetitive existence and work. People must find in themselves a deeper sense of existence, a deeper meaning in life, an unending adherence to a long history of culture and loyalty. The Japanese ronin existed in an era in Japan where there were no more wars to fight. The samurai was regarded as a warrior class that earns deep respect from the people. In fears that the Japanese spirit might be slowly slipping away, it is very timely that the story of the 47 Ronin is retold. Should the author have existed in feudalistic Europe, the story would have been different because in Europe, treatment of knights is very different. The knights were given land titles to govern. Knighthood is only given to the noblemen. It is more of a status quo rather than a binding story for loyalty and respect.
After increased fear of nuclear attacks during the cold war, materials to build fall out shelters were distributed by the government and other organizations. The shelters were meant to protect people from radiation in case of a nuclear attack.
The government communicated about the fallouts to the public in several ways:
i) Schools were supposed to have drills and study materials on how to be protected.
II) Information booklets were distributed accompanied by frequent radio PSAs
iii) Children songs were created with information on nuclear preparedness.
iv) Public videos were made and shown to the public i.e. "Duck and Cover" film for kids.
