Harmonium (2017) Timeline Explained – Every Event in Order

Toshio hires Yasaka seeking a fresh start for himself and his family, wanting to help an old acquaintance get back on his feet. However, the decision is more complicated than simple goodwill - Toshio feels a debt of guilt toward Yasaka because he was partially responsible for the crime that sent Yasaka to prison. This underlying guilt explains why Toshio offers him a place to stay and work, despite the risk it poses to his family.

Toshio admits that he helped restrain the murder victim while Yasaka strangled him. This means Toshio was an accomplice in the killing, not merely a bystander. He allowed Yasaka to take the full blame for eleven years, leaving him to serve the entire prison sentence alone while Toshio returned to his normal life with his family.

Foreshadowing: Earlier in the film, Yasaka reveals he spent eleven years in prison for murder but hints that the blame was not entirely his.

When Toshio returns home, he finds Hotaru injured and unresponsive with Yasaka standing over her. Yasaka repeatedly calls out Toshio's name, but Toshio is too focused on his daughter's condition to respond or hear what Yasaka is trying to say. Yasaka then leaves and disappears. The film never explicitly shows what happened to Hotaru, leaving the precise nature of the incident ambiguous.

Foreshadowing: Earlier, Yasaka goes for a walk after being rejected by Akie and encounters Hotaru in town.

Akie reaches her breaking point after years of living with the weight of secrets, guilt, and the trauma of Hotaru's injury. When she sees what appears to be an image of Yasaka smiling at her from the bridge, she makes a desperate decision to end her own life, taking Hotaru with her. The act represents the culmination of her psychological deterioration under the strain of the family's buried secrets and Yasaka's destructive presence.

Foreshadowing: The film shows growing romantic tension between Akie and Yasaka, her rejection of his advance, and the emotional toll of keeping Toshio's murder involvement secret.

Takashi is Yasaka's illegitimate son, born to a woman Yasza was involved with before his imprisonment. He discovers that Yasaka had been writing letters to his mother before disappearing, which leads Takashi to seek out Toshio. Takashi wants to understand his father and possibly find him, which is why he takes the job at the machine shop.

The moment Toshio removes his white clothing to reveal a red shirt underneath serves as a visual turning point in the film. This color shift signals a darker transformation in his character and marks the beginning of the film's more tragic second half. The white represents the facade of innocence and normalcy Toshio has maintained, while the red beneath suggests the violence and guilt that were always present underneath.

Yasaka bears the full responsibility for a murder that Toshio helped commit. While Yasaka did the killing, Toshio participated by holding the victim down. Yet Toshio escaped any consequences and lived freely for years while Yasaka served eleven years in prison. This inequity fuels Yasaka's bitterness toward Toshio, creating the underlying tension that eventually destroys the family.

Foreshadowing: Yasaka's initial arrival seems friendly, but the film gradually reveals the depth of his resentment toward Toshio.

After the night of her injury, Hotaru becomes disabled and non-verbal. She requires constant care and cannot speak. Eight years later, she is still living with her parents but in a significantly diminished state. Takashi, the new assistant, shows interest in her and sketches her, though Akie becomes fiercely protective and eventually ejects him from the house when he gets too close.

Toshio and Akie receive a tip about Yasaka's location and, along with Takashi, pursue what they intend to be a confrontation that may end in killing Yasaka. Takashi offers to be sacrificed in their plan, but they reject this. However, the tip proves false - the person they confront only vaguely resembles Yasaka. This failed pursuit demonstrates how consumed they have become by their desire for revenge or closure.

Foreshadowing: After Akie learns of Toshio's involvement in the murder, tensions escalate significantly.

The film ends with ambiguous outcomes. Akie regains consciousness after being pulled from the water. Toshio desperately attempts to resuscitate Hotaru, and Takashi also pulls Hotaru from the river. Both Hotaru and Takashi are unconscious on the riverbank. The screen cuts away before we learn whether either survives, leaving their fates unresolved and reinforcing the film's bleak, open-ended conclusion.
