Kei Kumai made just 19 films films in his 40 year career, but even since his earliest days he ranked among the most fearless of directors, ready to confront the most unpleasant or taboo aspects of contemporary Japan. His first film, The Long Death, interrogated wartime guilt through drawing inspiration from a real life 1948 mass poisoning case in which materials manufactured in a Manchurian lab may have led to the deaths of post-war civilians. Having begun in this possibly controversial vein, Kumai pressed on with 1965’s A Chain of Islands (日本列島, Nihon Retto, AKA The Japanese Archipelago) which he set in 1959 as Japanese youth protested the renewal of the ANPO treaty which placed Japan under the military protection of the American Armed forces in return for allowing the presence of those forces on Japanese soil.
Despite the contemporary setting Kumai opens with a explanatory voice over detailing the depth of the American military presence and the function of the CID which exists solely to investigate crimes committed by American servicemen. The CID is staffed by both Americans and Japanese nationals who, the voiceover explains, often feel conflicted in stepping onto American soil each morning as prolonged exposure gradually erodes their sense of difference and finally of “Japaneseness”. Akiyama (Jukichi Uno) is a translator/investigator at CID and he’s about to be handed an unusual request from his boss – reopen a cold case from the previous summer in which an American Sergeant was found floating in Tokyo bay. Akiyama’s new boss was a friend of the late soldier and would like to know what happened.
Akiyama’s investigations lead him down a dark path of corruption, murder, conspiracy, and governmental complicity. Beginning to investigate the case, Akiyama discovers that nothing is quite as it seems. A couple of policeman from the original investigation arrive to help him and echo their frustrations with the way the case was handled. Despite the police investigation, the American authorities did their best to interfere – commandeering the body and claiming jurisdiction in contravention of Japan’s standing as a sovereign nation. The Americans are no longer occupying forces but honoured guests who should obey international protocol in cases like these, but they rarely do. Despite the existence of the CID, crimes by American servicemen are generally covered up as the military insists the matter will be dealt with internally only for suspects to be suddenly “transferred” overseas.
Sgt. Limit was, however, one of the good ones and Akiyama’s investigation seems to point towards a murder and cover up instigated because Limit had got too close to the truth in investigating a sudden flood of counterfeit cash. The Americans, to the surprise of all, are only the middle man in the grand conspiracy which leads right back to the dark heart of Japan and the vast spy networks operated during the militarist era. As might be expected, these valuable networks are left wide open with the collapse of Japanese fascism but are perfectly primed to facilitate widespread crime spanning the Asian world and all with the tacit approval of the American and Japanese states.
Kumai also implicates the spy ring in a series of “mysterious” rail incidents, but makes sure to reserve some of his ire more the more usual injustices. Akiyama is caring for his young nephew whose father was killed in mining explosion which has claimed the lives of nearly every young man in the village leaving his sister unable to cope with her children alone. He is also battling a personal tragedy which is intensely connected to his decision to join CID which is currently inundated with cases of rape and murder in which American servicemen are implicated. The “foreign” becomes suspect but mostly for its hypocrisy as in the Catholic priest who becomes a major suspect in subverting the legitimate devotion of a Godly woman who only sought to live under the Christian teachings of love and kindness, while the American forces claim to stand for honour and justice but actively facilitate organised crime at an interstate level to further the progress of Capitalism whilst also facilitating civil unrest in volatile nations for financial and political gains.
That all of this happens immediately before the renewal of the ANPO treaty is no coincidence and Kumai even includes aerial footage of the mass protests filling the streets around the Diet building as the youth of Japan question why their nation has seen fit to make itself so complicit in the questionable foreign policy of another country. The outcome looks bleak for our protagonists who discover themselves to be mere pawns at the mercy of greater forces which cannot be circumvented or denied, but just as it all looks hopeless a new hope arises. Pledging to fight harder and continue the work which has been started, those left behind dedicate themselves to equipping the young with the tools to build a happier, fairer world in contrast to the one they seem primed to inherit from those who should know better. The final sequence shows us a young woman walking gloomily past the Diet building which seems to be looming over her as a veritable symbol of oppression but then her face brightens, her step quickens and she leaves the Diet far behind to walk forward towards the work which awaits her.
