Kaidan (2007) – Full Plot Summary & Ending Explained

Read the complete plot breakdown of Kaidan (2007), including all key story events, major twists, and the ending explained in detail. Discover what really happened—and what it all means.

In feudal Japan, Hitomi Kuroki plays Toyoshiga, a respected teacher who runs a school for young girls in Edo, and her sister Osono moves through the shadow of a debt that once cost their father his life at the hands of Shinzaemon Fukami, a samurai whose action sets a long shadow over the family. The killer Shinzaemon, after the tragedy, kills his wife and takes his own life, leaving their baby Shinkichi in the care of his uncle, a fate that quietly threads through the years. The tale widens as Toyoshiga and Shinkichi are drawn together by affection that grows into something closer to partnership, even as the past nears with uneasy echoes.

Years pass, and Toyoshiga becomes a respected teacher who oversees a school in Edo. She falls in love with a young tobacco seller named Shinkichi, Kikunosuke Onoe V playing a man who finds himself drawn to Toyoshiga’s resolve and grace. They decide to live together as husband and wife, a union that unsettles the delicate balance of the school and the wider community. Shinkichi begins to flirt with the students, especially Ohisa, who is portrayed by Mao Inoue. The dynamics at the school begin to fray as Toyoshiga’s joy turns brittle; the students leave one by one, and her sister Osono grows distant, ultimately deciding to leave in response to the mounting strain between them.

A rift widens between Toyoshiga and Shinkichi as their quarrel intensifies. He challenges her sense of control and in a moment of anger, Shinkichi wounds Toyoshiga with the bachi of her shamisen, striking her on the left brow. The breach heals only slowly, and Toyoshiga’s illness grows from the wound, casting a pall over their relationship. During a festival, Oisa—Ohisa, a figure linked to the school’s circles—meets Shinkichi while he is there to obtain medicine for Toyoshiga; they flee toward a hotel room, and he promises to run away with her. Toyoshiga’s patience fractures, and she urges him to stay by her side in life and, perhaps, at its end.

When Shinkichi visits his uncle’s house, he discovers Toyoshiga waiting there with a quiet, devastating resolve. She tells him that he may leave, but she asks him to promise to be by her side when she dies. After Toyoshiga passes, a letter she leaves reveals a chilling warning: if he remarries, she will haunt his new wife until the latter dies.

If he remarries, she will haunt his new wife until the latter dies.

Oisa and Shinkichi elope and flee Edo, but their escape is compromised by a rainstorm that slows their path and twists their fate. Toyoshiga’s vengeful spirit haunts them as a terrifying apparition appears on the road, and in a moment of fear, Shinkichi strikes with a scythe, only to realize he has fatally wounded Oisa’s neck. He falls unconscious on the road and awakes later in the house of a wealthy man, where he and Oisa’s body are found. He escapes to Hanyo, where he crosses paths with Osono. The two mourn Toyoshiga together, and Osono helps Shinkichi find work, eventually placing him in a position as the master of a house.

The wealthy couple who foster Shinkichi want him to marry their daughter, Orui, who is Ohisa’s cousin. A near-fatal blue snake attack leaves Orui burned in a fireplace, and as Shinkichi tends to her injuries, he notices that the burn matches a scar Toyoshiga once bore on her brow. This eerie parallel pushes him to accept the match with Orui, and soon they are married.

Shinkichi and Orui welcome a daughter, a pale child marked by a scar on her left brow. The girl’s unusual pallor and growing oddities begin to trouble the new family, hinting at a legacy rooted in Toyoshiga’s tragedy and the dark currents that have flowed through the generations.
