A Story of Nuclear Terrorism That Provoked Its Era

Kazuhiko Hasegawa's The Man Who Stole the Sun shocked Japanese cinema in 1979. Kido, an unremarkable junior high school science teacher, steals uranium-235 and builds a homemade atomic bomb in this film's startling premise, confronting the taboos of its time head-on. Depicting the possibility of nuclear terrorism in Japan at the height of nuclear power's popularity, it provoked controversy through its bold subject. Lead actor Kenji Sawada's solitary performance and the script's cool, meticulous portrayal of nuclear weapon construction gave audiences an unsettling sense of reality. The paradox that something is frightening precisely because it is technically possible forms the film's starting point.
A Fusion of Realism and Allegory

The Man Who Stole the Sun stands out for its remarkable fusion of realism and allegory. Hasegawa depicts the seemingly unreal act of nuclear weapon construction in an extremely everyday, detailed manner. Supervised by experts, the technical portrayal is coldly accurate, and its matter-of-fact progression sends chills through viewers. At the same time, Kido's guiding motives go beyond realistic motivations, taking on the allegorical meaning of a fundamental challenge to modern civilization. His expressionless delivery and detached actions symbolize criticism of the system itself rather than an individual's inner life. This dual structure elevates the film beyond suspense into a work of profound ideas.
A Biting Critique of Social Systems

The turning point comes when Kido places capsules containing uranium around Tokyo and offers the government a deal. Surprisingly, he demands not money but ten minutes of television airtime for a message. He uses it to discuss the dangers of nuclear power and the deception of its management system. Through this premise, Hasegawa directs incisive criticism at nuclear policy and information control of the time. Scenes depicting the confusion and responses of bureaucrats, police, and the media expose the vulnerability of social systems in an emergency. Particularly memorable is Tsutomu Yamazaki as a journalist pursuing the truth despite reporting restrictions, questioning journalism's role in a society of controlled information.
Reassessment as a Prophetic Film

At the end of The Man Who Stole the Sun, Kido is shot dead by police, and his bomb destroys itself because it lacks sufficient coolant. Yet his questions remain unresolved and are left to the audience. More than 40 years after release, for those of us who have experienced the Fukushima Daiichi nuclear accident, the film can seem all too prophetic. From today's perspective, it was more than entertainment: it was an important warning questioning the relationship between science, technology, and human society. Hasegawa's cold-eyed perspective and sharp social criticism continue to challenge us across time. The Man Who Stole the Sun retains its brilliance as an anti-establishment masterpiece of Japanese film history and a prophetic work.
