As The Last War (世界大戦争, Sekai Daisenso) points out, by 1961 16 years had passed since the end of World War Two during which Japan had begun to rebuild itself, heading into a period of unprecedented economic prosperity with the Olympics already on the horizon. But the early 1960s were also a time of increased international tension as the Cold War mounted and many in Japan feared being pulled into another conflict especially with the Korean War not quite so much in the distant past. Toho had become the home of special effects cinema and such films were often coloured with strong messages of peace and social responsibility as humanity banded together to combat an existential threat be it a giant monster or mad scientist. The Last War is no different in that regard, but sadder in showing us that the end of the world may come suddenly and without warning and that if we for a second become complacent it could already be too late to stop it.
Patriarch Mokichi (Frankie Sakai) has made a decent life for himself after the war working as a driver. His wife, Oyoshi (Nobuko Otowa), is in poor health and he dreams of buying a house by the sea where she can live in comfort. Meanwhile, they have a grownup daughter, Saeko (Yuriko Hoshi), born before the war, and two much younger children, a girl, Haru, and boy, Ichiro. They are a very happy, very ordinary family who are beginning to think that their days of hardship are finally behind them and they have escaped the war’s shadow. The only note of potential conflict lies in the fact that Saeko wants to marry a family friend, Takano (Akira Takarada), a sailor, and is afraid of Mokichi’s reaction, especially as he keeps trying to set up matches for her.
In fact, having lived through the war Oyoshi and Mokichi are certain that nothing like that is going to happen again, even if the younger generation is filled with anxiety. “Who could ever profit from the destruction of the Earth?” Mokichi not unreasonably asks, signalling his newly consumerist world view. Mind you, he adds, everyone knows the alternative to calamity is hard work, “you have to work hard for peace”.
Mokichi has indeed been working hard, but has perhaps begun to neglect other areas of his life in his desire to become rich even if that desire is only to make his family more comfortable and give his children better opportunities than he had. Brought over to see a new TV set now on sale, he scoffs that he already has one, “Who needs a second TV?” he asks, but on hearing the news that tensions are rising because a military plane has gone down off the coast of Africa, his first thought is to get on the phone to his broker and junk his real estate stocks for shares in aeronautics. Mokichi is unconvinced by an old man selling potatoes on their street who apparently lost everything in Hiroshima and has since become a devoted Christian donating most of his profits to anti-nuclear charities, describing him as just “showing off”, firmly believing that nothing like that is ever going to happen again. “I cannot accept it” he says, “what would be the point of the aspirations of humble folk like us if we’re all destined to go poof into extinction?”.
As the only nation to have directly experienced nuclear war, the intense fear of its recurrence is indeed understandable. If a nuclear war escalates, it will be the end of everything. All human endeavours over thousands of years will be mere dust. There will be no weddings, no births, no graduations, no grand discoveries, just nothing. When the bomb does indeed hit, the scenes of devastation must have proved extremely traumatic for many in the audience as buildings crumble ominously, the sky turns a fiery red, the streets run with lava, and we can see the outlines of charred bodies lying among the wreckage. The tip of the Diet building sits neatly atop the rubble as if in rebuke of the political failures which, despite the best efforts of the Japanese politicians who make an effort to govern responsibly and are honest with the electorate while advocating strongly for peace through diplomatic channels, have led to the literal end of the world. “You have to work hard for peace” the closing title card reminds us. “We can stop this before it happens, but we have to work together”. “I won’t let you destroy our happiness” Mokichi had screamed at the void, but in the end he was powerless. All it takes is a minor slip, and the world as we know it will cease to be.
