During his distinguished career as a director, Masato Harada (1949-2025), who passed away in December 2025, explored the pervasive nature of systemic corruption in Japanese society. Films such as Kamikaze Taxi (Fukushu no Tenshi, 1995), Spellbound (Jukaku, 1999), Killing for the Prosecution (Kensatsu gawa no zainin, 2018), Hell Dogs (Heru doggusu, 2022) and Bad Lands (2023) examine the complex intersections of politics, economics and crime, highlighting the often-blurred boundaries between these spheres. This article takes a closer look at Killing for the Prosecution, revealing the blurred lines between justice and crime.
A tale of revenge
In Killing for the Prosecution, the protagonist Takeshi Mogami (Takuya Kimura), is introduced as a public prosecutor who espouses an ideal of justice grounded in the pursuit of truth. During a law seminar, he asserts that a prosecutor who becomes committed to a narrative of his own making ceases to serve the law and instead undermines it. Several years later, Keiichirō Ōkino (Kazunari Ninomiya), one of the seminar attendees, joins Mogami at the Criminal Investigation Division. As Ōkino works alongside the man he admires, he gradually encounters a more ambiguous and troubling side of his mentor, prompting him to question both Mogami’s integrity and the ideals of justice he once championed.
One of the suspects in the murder case of an elderly couple is Shigeo Matsukura (Yoshi Sakō). It was revealed to the police that he and his older brother, who were both adolescents at the time, had committed the abduction and rape of a young girl. In an effort to conceal their crime, the perpetrators subsequently took the lives of their victim, in addition to the victim’s parents and brother. The sixteen-year-old Matsukura, was sentenced to five years’ imprisonment while his brother took his own life. Furthermore, Matsukura was the primary suspect in a separate murder case that occurred sixteen years prior to the murder of the elderly couple. On this occasion, the victim was a young student named Yuki, who was killed in her final year in middle school [That means that she was around fifteen years old, when she died; author’s note]. As Matsukura had remained stubbornly silent throughout all the interrogations, it had not been possible to prove his guilt. He had to be released and Yuki’s murder remained unsolved. Mogami is convinced that Matsukura is responsible for Yuki’s death. Yet he has a much deeper reason to convict the suspect. Brief flashbacks reveal that Mogami was friends with Yuki, and indeed was in love with her.
It is evident that Mogami swiftly directs the investigative efforts towards Matsukura. He wants the man found guilty at any cost. Especially since, during an interrogation conducted by Ōkino – which Mogami is overhearing from another room –, Matsukura confesses to Yuki’s murder. He even relishes revealing his guilt, because he knows that he can no longer be convicted of this crime, as the statute of limitations had expired [It was only in 2010 that a law was passed removing the statute of limitations for capital offence; author’s note]. The situation presents a dilemma for Mogami, who is becoming increasingly obsessed with Matsukura whom he wants to charge and convict for the latest murder. When another suspect emerges and the police begins to focus their attention on him, Mogami resorts to extreme measures, taking the law into his own hands.
Revenge is a universal theme and a persistent feature of Japanese culture. Its best-known example is arguably the story of the 47 ronin who avenged their lord’s honour in the early eighteenth century. In the annals of cinematic history, Akira Kurosawa’s seminal work The Bad Sleep Well (Warui yatsu hodo yoku nemuru, 1960) serves as another poignant example. Kurosawa’s film offers a compelling narrative that portrays self-justice as a desperate measure within a profoundly corrupt system, where the intertwined forces of politics, industry and organised crime perpetuate a pervasive sense of despair and hopelessness. In Harada’s Hell Dogs, the protagonist Gorō Idezuki (Jun’ichi Okada) is a police officer who has infiltrated a yakuza clan. The setting is the world of organised crime which is depicted as a violent underworld working under the disguise of a modern enterprise operating at a global level. In Akio Fukamachi’s novel Takenōchi-ke, the source material on which Hell Dogs is based, the emphasis is placed on Gorō’s identity crisis, his growing identification with his yakuza role and his disgust for the violent and not always legal methods of his superior at the police which come close to self-justice. In contrast, Harada shifts the focus on the ardent desire of revenge which determine Gorō’s actions. The protagonist is depicted as a solitary figure, embodying the archetype of the lone wolf hero. However, this persona is juxtaposed with the character’s profound personal trauma, stemming from his professional failure as a police officer to save the life of a woman he had a romantic attachment to. The police unit that recruited Gorō as an undercover agent operates covertly as a shadow organisation with the objective of targeting organised crime and dismantling the yakuza clan. It is evident that the objective of the mission is to perpetrate murder, a blatant contravention of the law. Hell Dogs provides no explanation as to who commissioned or controls the secret unit. The mere existence of such phenomena is indicative of systemic weakness within the legal system and wider society.
Beyond the law
Mogami is culpable of violating the law, fabricating evidence, collaborating with the yakuza and ultimately taking a life in order to bring Yuki’s murderer before the courts and secure a death sentence. Although his actions appear motivated by a desire for vengeance, they are nevertheless characterised by careful deliberation. While the film depicts him as committing a grave act of violence, it simultaneously cultivates ambiguity regarding the extent of his moral corruption, leaving open the question of whether he is as cold-blooded as his actions imply. As he unloads the gun he intends to use to kill his victim, he experiences a bout of vomiting. His ambiguity is also expressed by the trauma he suffers from after Yuki’s the murder. He seems to live primarily for his job. A few brief scenes depicting his private life make it clear that he is in a loveless marriage. In this respect, the character conforms to genre conventions. Nevertheless, there are also scenes that show Mogami in a private setting with friends and colleagues, which gives Takuya Kimura the opportunity to demonstrate a wider range of expressions – an opportunity he makes compelling use of.
Mogami has constructed a narrative of Matsukura’s guilt and is determined to uphold it at any cost. This determination leads him to manipulate those working alongside him, including Ōkino. The younger man remains committed to an idealised conception of justice, one that Mogami himself had promoted in the past. In response to a colleague’s remark that justice is a “hypocritical fantasy,” Ōkino replies: “I’m carrying the torch for Mogami’s justice.” But as he gradually realises that his superior’s actions are driven by a desire for retribution, he begins to question his behaviour. He reminds Mogami of his own words: “A prosecutor who is obsessed with his own idea of justice becomes a criminal.”
Law and justice in a broader context
While Ōkino remains committed to the truth and vents his frustration, Mogami defends his version of events: “Times change. So does justice. Today you must be obsessed with justice to be strong.” Above all, however, he justifies himself by emphasising his importance within the system as a public prosecutor who combats corruption. Alongside the revenge story, Harada develops a subplot in which Kazuki Tanno (Takehiro Hira), Mogami‘s friend since middle school, has been arrested for bribery. It turns out that Tanno is a victim of the scheming of his fabulously wealthy father-in-law, a politician tipped to be the next prime minister.
Harada takes a critical look at a political system that is rotten to the core. Mogami can only carry out his revenge with the help of the yakuza. In Killing for the Prosecution, the connection between the legal system and organised crime is driven by personal motives. These, however, suggest deeper and more complex connections between justice and crime. The relationship between Mogami and Suwabe (Yutaka Matsushige), a fixer for the yakuza he asks for help, is explained in the frame of Japan’s wartime past. Mogami’s grandfather and Suwabe’s father were both survivors of the 1944 Battle of Imphal, a devastating defeat for the Japanese Imperial Army. Suwabe expresses an lifelong gratitude to Mogami and his family, because Mogami’s grandfather rescued his father during the campaign. In a dream, Mogami is haunted by visions of the Japanese Imperial army’s harrowing retreat, which claimed the lives of thousands of soldiers. He sees himself surrounded by men dying from starvation and disease, caught amid the suffering and the chaos of the withdrawal.
The wartime subject is indicative of an unresolved past that continues to exert a profound influence of Japanese society, transcending temporal boundaries and spanning multiple generations. The one-sided portrayal of Japanese soldiers as victims can be viewed critically. Nevertheless, the collective memory of a nation that has sacrificed its own people – soldiers and civilians alike – is also an important factor that contributed to the rise of pacifism in post-war Japan. Pacifism is increasingly under threat in twenty-first century Japan. In his film, Harada explores the close connection between the legacy of World War II and contemporary anxieties surrounding remilitarisation. While Tanno’s father-in-law supports remilitarisation, Mogami maintains that prosecutors such as himself are essential to preventing both remilitarisation and the emergence of a new dictatorship.
The wartime experience can also be interpreted as a metaphor for the state of the legal system. The Battle of Imphal is regarded as one of Japan’s most poorly planned wartime operations. Harada draws a parallel between the inflexibility of many Japanese military commanders, who sacrificed their soldiers during the war, and Japan’s contemporary legal system, which is portrayed as rigid and deeply flawed. However, Mogami’s actions contradict his intentions, evoking the dogmatic authoritarianism that afflicted his grandfather’s generation.
Order and chaos
Although Ōkino does not accept Mogami’s justifications, the latter’s crimes suddenly seem trivial compared to those of the wartime Japanese military government or the machinations of certain politicians. However, the film does not descend into populist discourse, partly because it focuses on the moral dilemma that both Mogami and Ōkino have to face.
Although they are only addressed superficially, wartime history, re-militarisation and corruption at the top of the political hierarchy are elegantly integrated into the narrative. This also applies to the brief sequence in which demonstrators campaigning for a driving ban on elderly road users can be seen in the background. Later, when an elderly driver appears to have caused a fatal accident, the political campaign takes on an unexpected resonance in the narrative. Furthermore, Harada, an admirer of classic Hollywood cinema and jazz music, elegantly incorporates a song by Dinah Washington, a singer that Yuki liked, into the soundtrack. The term “elegant” is also applicable to the visual design which is characterised by opulent framing, lighting and camera movements. Numerous shots of modern towers, an architecture dominated by glass and metal, linearity and shades of grey and blue suggest a world in order. These shots are in stark contrast with the carnivalesque atmosphere in a narrow street where street artists perform and people feast. Not less chaotic is the party sequence in which Matsukura and his lawyers celebrate their success, Matsukura having been found not guilty in the murder case of the elderly couple. Tanno’s funeral service seems just as much as a farce, with professional mourners moving rhythmically in front of a huge portrait of the deceased who has been sacrificed by his father-in-law.
Critical views on the legal system
Harada’s film is divided into three chapters, with each chapter being represented by a tarot card. The initial chapters bear the titles “The Magicians” and “The Judgment”, respectively, while the concluding chapter is entitled “The Fool”. One may ask whether Mogami resembles the Fool in the tarot, in the sense that he cannot be captured by his opponents and is therefore invulnerable to defeat. Matsukura is depicted in a highly negative light, as a monster, an unpleasant and abject individual, on the verge of madness, a person who disrupts the established order. This clichéd depiction of the villain serves to mitigate the perceived culpability of the prosecutor. Nevertheless, Harada refrains from straightforward identification with Mogami, whose actions are challenged by Ōkino’s pursuit of truth.
The search for truth is a prominent theme in many recent Japanese television series taking place in the world of law and justice. 99.9 – Criminal Lawyer (2016, 2018 and 2021), Ichikei’s Crow – The Criminal Court Judges (2021), Antihero (2024), Destiny (2024), Okura- Cold Case Investigation (2024), Sins of Kujo (2026) and Tarusagi Bros. (2026) deal with corruption and illegal means made use of by the police and/or the prosecution. Mogami is advised by a superior to hand over the new murder case rather than risk losing it. This is explained by the pressure on Japanese prosecutors to achieve a 99.9 % conviction rate, a theme that lies at the heart of the series 99.9% – Criminal Lawyer. Tarusagi Bros. centres on the themes of revenge and the statute of limitations: two brothers, both police officers, seek revenge for the murder of their parents which occurred before the new law abolishing limitation came into effect.
Killing for the Prosecution deals very obviously with topics which concern present-day Japan without delving deeply enough into most of its themes. This apparent superficiality might leave viewers feeling dissatisfied and it negatively impacts the critical portrayal of the legal system. However, the conflicting motivations that drive the main characters produce nuanced human portraits and expose the moral ambiguity at the heart of the narrative, inviting viewers to draw their own conclusions.
