In the post about Japan’s summer tradition of telling ghost stories, we briefly mentioned two of the country’s most famous ghosts: Okiku from Banchō Sarayashiki and Oiwa from Yotsuya Kaidan. This time, let’s meet Oiwa.
Her story begins not with a ghost, but with a husband who wants a different life.
The Story of Oiwa
民谷伊右衛門（たみやいえもん・Tamiya Iemon） was a 浪人（ろうにん・rōnin）, a samurai without a master. He was married to a woman named お岩（おいわ・Oiwa）, but theirs was not a happy household. Iemon had already murdered Oiwa’s father after the man discovered his wrongdoing and tried to separate him from his daughter.
Oiwa knew none of this.
After giving birth, she was weak and exhausted. The family was poor, Iemon was dissatisfied with his situation, and then an opportunity presented itself: a young woman named Oume fell in love with him. More importantly, Oume came from a wealthy family.
For Iemon, marrying her offered the possibility of escaping poverty and rebuilding his position. There was only one “problem”: he already had a wife.
Oume’s family sent Oiwa what she believed was medicine to help her recover from childbirth. It was poison.
The drug did not kill her immediately. Instead, it horribly disfigured her face. One side swelled and twisted. Her eye drooped. Her hair began to fall out.
In one of the most famous scenes in the story, Oiwa sits before a mirror and combs her hair. At first, she does not fully understand what has happened. Then strands begin coming loose. She pulls the comb through again, and more hair falls.
Slowly, Oiwa sees what has been done to her. And eventually, she learns why.
Iemon no longer wants her. He wants Oume, and he wants Oiwa out of the way.
What follows differs somewhat depending on the version of the story, but none of them end well for Oiwa. She dies.
But her anger does not.
Oiwa returns as an 怨霊（おんりょう・onryō）, a vengeful spirit bound to the world by an overwhelming grudge. And now Iemon begins seeing her everywhere.
Her ruined face appears where it should not. The people around him seem to become Oiwa before his eyes: Her face emerges from a paper lantern, and reality and hallucination blur together.
Iemon tries to escape, but every attempt only drags him further into the consequences of what he has done. The comfortable new life he betrayed Oiwa for begins collapsing around him, and the woman he thought he could simply discard refuses to disappear.
The Ghost Story of Yotsuya
That’s the heart of 四谷怪談（よつやかいだん・Yotsuya Kaidan）, or The Ghost Story of Yotsuya. The full title is 東海道四谷怪談（とうかいどうよつやかいだん・Tōkaidō Yotsuya Kaidan）.
It was written by the kabuki playwright 鶴屋南北（つるやなんぼく・Tsuruya Nanboku IV） and first performed at Edo’s Nakamura-za theater in 1825. Major traditional venues such as Kabukiza Theatre in Tokyo and the Minamiza Theatre in Kyoto still feature it as part of their summer programs today.
The original play is considerably more complicated than the basic Oiwa story. There are murders, betrayals, mistaken identities, family vendettas, and multiple plotlines woven together. It was originally performed alongside Kanadehon Chūshingura, the famous tale of the Forty-Seven Rōnin, with actors playing roles in both productions. But interestingly, it was Oiwa who became immortal.
Part of the reason was the spectacle: Yotsuya Kaidan was packed with elaborate stage effects designed to shock its Edo-period audience. Oiwa’s transformation was performed in front of the crowd, the hair-combing scene made her hair appear to fall out onstage, and her corpse appeared in grotesque and unexpected ways.
Perhaps most famously, Oiwa’s face emerged from a 提灯（ちょうちん・chōchin）, or paper lantern.
While the idea of “wronged woman returns as a vengeful spirit” wasn’t invented by Yotsuya Kaidan, Oiwa became one of its most famous embodiments in Japan. You can see echoes of her in later Japanese horror, especially in film: the pale skin, the long black hair, the distorted face, the grudge that survives death, and so on.
Was Oiwa a Real Person?
Well, this is where the story gets a little stranger.
There does appear to have been a real woman named Oiwa associated with the Tamiya family in Yotsuya, but the historical Oiwa probably had very little in common with the ghost we know today.
Nanboku drew from existing legends, rumors, and real incidents when creating Yotsuya Kaidan, but much of the horrifying story surrounding Oiwa was theatrical invention. Over time, though, the boundary between the fictional Oiwa and the supposedly real woman became blurry.
There are still places in Tokyo associated with her, including 四谷於岩稲荷田宮神社（よつやおいわいなりたみやじんじゃ） in Yotsuya. Her reputed grave can also be found at Myōgyōji in Nishi-Sugamo.
Actors have also traditionally paid their respects to Oiwa before performing Yotsuya Kaidan — there’s a longstanding superstition that productions which fail to honor her may suffer accidents or other misfortune. Even today, performers sometimes visit sites associated with Oiwa before staging the play.
You don’t have to believe in curses, of course. But if I were about to spend several weeks pretending to poison Japan’s most famous vengeful ghost in front of an audience, I’d probably stop by the shrine too, just in case…
