The True Crimes that Inspired the Disturbing Japanese Thriller ‘Missing’ (2021)
The Japanese crime thriller Missing (aka Sagasu, 2021) was inspired, in part, by a high-profile murder case from 2017. Here is the true story that inspired the grisly fictional killer.
What would you do if your father left to track down a serial killer, but he didn’t return home? That’s the central premise of Missing, one of 2022’s most gripping crime thrillers. Missing is a twist-filled mystery from Japan about a serial killer who performs disturbing acts. The film becomes even more disturbing when you learn that the killer in the movie was inspired by true events.
What is ‘Missing’ About?
As Missing begins, we get to know the relationship between a single father, Satoshi Harada, and his high-school-aged daughter Kaede. Kaede has a serious demeanor and is quite mature for her age. This is likely due to the fact that her father is initially portrayed as being impulsive and childlike. Kaede’s mother is not in the picture, though the reasons for her absence are revealed later in the movie. What is made clear early in Missing is that something tragic has happened, and Satoshi and Kaede are in a bad place emotionally.
Satoshi works in construction, but he and Kaede are struggling monetarily. One night, Satoshi reveals to his daughter that he spotted a wanted serial killer whose capture could earn them a hefty reward. The next day, Satoshi is gone. The authority figures in Kaede’s life believe Satoshi has abandoned her, which leads Kaede to search for her father herself. Kaede’s investigation leads her ever closer to a dangerous killer, and her life is forever changed by her discoveries.
The driving force in Missing is Kaede’s search for her father. Along the way, the film’s point of view switches to other characters, filling in pieces of the mystery and showing some of the same events from multiple perspectives. It’s an effective technique that builds the tension and drama for certain characters while getting quite dark and disturbing when switching to the perspective of the killer. So in effect, Missing becomes a tense journey that shifts between being emotional, scary, exhilarating, and even humorous.
What Was the Inspiration for ‘Missing’?
Director and cowriter Shinzo Katayama has said in interviews that he researched true crimes in Japan when coming up with ideas for Missing. However, he is hesitant about revealing any specific killers or crimes he incorporated into the script. The one real-life story that Katayama talks about that directly inspired the movie involves the director’s own father.
When Shinzo Katayama was in high school, his father told Shinzo that he recognized a man wanted for murder while riding a train. Shinzo didn’t believe him, but years later when the killer was caught, Shinzo realized that his father was telling the truth. That incident stuck with Shinzo, and he ended up using his father’s chance encounter as the reason Satoshi gives to Kaede before he goes missing. Shinzo Katayama hasn’t revealed the name of the killer his father saw, so any guesses about their identity would be pure speculation. However, the killer in Missing does bear a strong resemblance to a much more recent real-life killer from Japan.
The Real Serial Killer ‘Missing’ is Based On
Please be aware that this section contains spoilers for Missing, and it contains descriptions of real-life assaults and murders.
The character Terumi Yamauchi is the fictional killer in Missing. Terumi preys on people who are contemplating suicide, offering “assistance” to those who aren’t able to go through with the act on their own. Terumi claims to be helping people, but he is clearly just taking advantage of people who are in a vulnerable state of mind.
Terumi chooses his victims based on their social media posts. If he sees someone posting about suicide, he will pretend to sympathize with them and offer, for a fee, to help them end their life. Terumi then meets with the victim, killing them whether they want to go through with it or not. He then dismembers the bodies, storing the body parts in coolers until he can figure out how to dispose of them.
Though Terumi Yamauchi is apparently an amalgamation of several killers, one real-life murderer stands out as a clear inspiration. In October of 2017, the dismembered remains of nine people were discovered in the tiny apartment of a man named Takahiro Shiraishi. Similar to how Terumi stores bodies in Missing, the severed heads and various body parts in Takahiro’s apartment were found stashed in coolers. That is far from the only similarity between fact and fiction though.
The real crimes occurred in Zama, a Japanese city about an hour’s train ride from central Tokyo. Takahiro Shiraishi moved to Zama in August of 2017, and the series of murders, known as the “Zama 9 Murder Case,” spanned from late August until Takahiro’s arrest on October 31, 2017. Takahiro set up a Twitter account and sought women who expressed thoughts of suicide on social media. He sympathized with them, often telling them that he would help them die or that he would kill himself along with them. After luring the women into a meeting, Takahiro sexually assaulted them before killing them.
In total, eight women and one man were murdered. The sole male victim was the boyfriend of one of the other victims who Takahiro thought would expose his crimes. Takahiro was caught when the brother of one of his victims investigated his sister’s disappearance and found her interactions with Takahiro’s Twitter account. The police were alerted, and that’s when they discovered the gruesome scene at Takahiro’s apartment.
While on trial, Takahiro’s defense team tried to make the case that their client should receive a lighter sentence because his victims asked for his help in dying, but Takahiro refuted his own attorney’s claims. Takahiro said none of his victims consented to their death. Takahiro was given the death penalty for his crimes in December of 2020, and as of this writing he is in prison awaiting the completion of his sentence.
As described above, the killer in Missing is hauntingly similar to Takahiro Shiraishi. From finding his victims through a social media app, to feigning sympathy towards suicidal people, to storing body parts in coolers, the connections are unmistakable. What might be the most chilling similarity is revealed late in the movie when the film’s killer remarks to his final potential victim that none of his previous victims actually wanted to go through with their suicide. Knowing that this remark is an echo of reality is a terrifying thought.
