The Eel

Takuro kills his wife after discovering her in bed with another man. He had returned home after receiving an anonymous note that led him to the affair, and the sight of the betrayal overwhelmed him with rage. After the murder, he immediately surrenders to the police, accepting the consequences of his actions.

Takuro uses the eel as his sole companion and confidant after being released from prison. The eel represents his own sense of isolation and self-imposed exile from human connection. He talks to it while keeping others at a distance, making the pet a physical manifestation of his emotional withdrawal from society.

Takuro maintains emotional distance because he believes he does not deserve happiness after his crime. He sees himself as unworthy of Keiko's love and fears that getting close to her would only bring her harm. His isolation is both self-punishment and a misguided attempt to protect her from his dark past.

The garbageman is a former prison inmate who recognizes Takuro from their time together behind bars. He becomes convinced that Takuro has not shown genuine remorse for his crime and views Takuro's new life with Keiko as undeserved happiness. His stalking is driven by a sense of moral judgment and jealousy over what he sees as Takuro's lack of proper penance.

Earlier in the film, Takuro recognizes the garbageman watching him at the shop, establishing the stalker's presence.

The garbageman attempts to rape Keiko as a way to punish Takuro by destroying the one thing that seems to bring him peace. He also leaves a letter on the barber shop door revealing Takuro's past murder, attempting to expose his crimes to Keiko and ruin his new relationship. His actions are driven by resentment and the belief that Takuro hasn't truly atoned for his sins.

The garbageman's earlier conviction that Takuro is unrepentant sets up his escalating violent actions.

When Dojima and his henchmen confront Keiko at the barbershop, she falsely claims to be pregnant with Takuro's child to protect herself and deflect their demands. The false pregnancy claim creates a momentary standoff, buying her time and shifting the power dynamic during the confrontation. This deception highlights her desperation and growing connection to Takuro despite his emotional walls.

Takuro returns to prison because a parole violation meeting determines he has violated the terms of his release. The exact violation isn't fully detailed in the summary, but it appears connected to the various disruptions caused by the garbageman's stalking and the conflicts surrounding Keiko. He is sentenced to serve another year, cutting short the fragile new life he had begun to build.

The buildup of external conflicts throughout the film creates the circumstances for his reimprisonment.

By releasing the eel back into the water, Takuro symbolically lets go of his self-imposed isolation and the guilt that has kept him imprisoned even while free. The act represents his acceptance of connection with Keiko and his willingness to embrace a future together, even though that future requires him to serve more time in prison. The eel's freedom mirrors his own emotional release.

Keiko returns to her former company as vice-president to regain financial stability and independence, especially after discovering her pregnancy complicates her situation with Dojima. By reclaiming her position and retrieving her mother's bankbook, she attempts to take control of her life back from the loan shark who had leverage over her. This decision reflects her growing strength and willingness to fight for her future.

The police discover that Keiko's mother never signed the power of attorney papers that Dojima was using to control her finances and property. This revelation undermines Dojima's legal claim over Keiko's assets and weakens his ability to manipulate her. The discovery shifts the power balance in Keiko's favor and exposes Dojima's fraudulent tactics.

Takuro goes eel hunting with Jukichi Takada as a rare departure from his isolated routine, showing a tentative opening to human connection. During these trips, Keiko prepares boxed lunches for him, which he initially refuses, demonstrating his reluctance to accept kindness. The eel hunting scenes illustrate the gradual, hesitant steps Takuro takes toward engaging with the world around him.
