Japan's postwar constitution renounces war, but rising tension with China over disputed East China Sea islands has reopened the debate over whether the country should build a full military again. The film follows that argument through the people who live inside it, including the director of Tokyo's Air Raid Museum, who resists changing the constitution and describes the museum itself as a message of peace aimed at the next generation. Interviews and archival material trace how memories of firebombing and defeat shaped Japan's pacifist identity, and how a new generation of politicians and citizens is weighing that legacy against present-day security fears. The camera moves between museum exhibits, public debate, and the diplomatic friction over the islands, letting both the historical case for pacifism and the contemporary case for rearmament make their strongest points. It is less a verdict than a portrait of a country deciding, in real time, what its constitution is actually for.
