Hikikomori Gets 20 Years for Killing Sister, Blames Asperger’s


A hikikomori who murdered the sister who had helped support his 30 years of reclusion has been given a 20 year prison sentence for murder, with the judge ruling that the 16-year sentence sought by the prosecution was too lenient and dismissing the defence’s arguments that it was all the fault of Asperger’s syndrome out of hand.

The unemployed 42-year-old man had lived as a hikikomori with the support of his older sister, then 46, for some 30 years, but started to blame his sister for his failure to end his reclusive dependency.

His unfounded resentment towards her culminated in him brutally stabbing her to death with a kitchen knife, resulting in him being arrested and tried for murder.

His lawyer rather optimistically sought a suspended sentence and probation instead of jail, arguing that he could not be held wholly responsible for the killing as his condition – he supposedly suffers congenital Asperger’s syndrome, a mental condition similar to autism and characterised by extremes of introversion – caused him anger management problems.

The Osaka court judge presiding was having none of it, and in fact thought the 16 year sentence the prosecution sought was too light, and sentenced him to 20 instead:

“After he had bodily and financially exhausted his elder sister, he irrationally opted to murder her.

The accused has displayed insufficient remorse for his crime and should he re-enter society there is concern he might re-offend in similar fashion.”

However, the judge did acknowledge his condition as a mitigating factor – although this merely worked against him as the judge suspected he would be unable to cope alone after killing the only person willing to take care of him:

“Your family does not want you living with them so you have nowhere to go, there is much worry about you re-offending. Keeping you imprisoned as long as the law allows will help protect public order.”

The defence plans to appeal the verdict, calling it “regrettable” that the judge did not buy their arguments that it was all the fault of Asperger’s syndrome and that he should be released, and chastising the judge for “basing a verdict on prejudice.”

Legal experts are nonplussed as well, complaining that “it is usual for the involvement of a mental illness to result in a reduction in sentencing, so there is a certain sense that the verdict is out of place.”

A mental illness charity also butted in to criticise the verdict:

“He did not regret his crime insufficiently, he merely did not understand what he was being told. Our worst fears about the lack of understanding of lay judges [a quasi-jury] have come to pass.”

However, as many mental health professionals do not even consider Asperger’s an “illness” and there is apparently as yet no history of it turning “sufferers” into sororicidal maniacs, even fellow sufferers may be none too sympathetic at their supposedly benign condition being stained with the stigma of bloody murder.

  • AS IF I CAN’T GET PISSED OFF ENOUGH! *sighs* I have Asperger’s too, but I have 10X the sense not to go to the stupid and horrible act that this ass has done. Pardon my language there, but after seeing plenty of BS punks like him trying to get away with the nonsense they come up with, even blaming on a disability that they probably never even looked up on the internet and such?! My god! What is with these people these days..?

  • I’m with the judge here. If he really doesn’t even understand what he did here then that’s all the more reason to put him down.

    Though a part of me wishes they’d let him go…he’d probably starve and curse himself to death…and I find that much more satisfying. Prison seems good in comparison.

  • I don’t mean to sound cold hearted and off topic, but howcome every other anonymous post on this is someone saying they have asperger’s? does apserger’s make you a lurker and somehow prevent you from being able to register for a free account on here? or did you all suddenly come down with it since reading this? and even if you have it, does that suddenly make you an expert on the topic?
    seriously, I don’t think it’s really relevent to the topic to say how you have something so there is no way it can cause that end result.
    It reminds me of a german saying that there is no way that they could ever have burned the jews alive because their grandma was such a nice old lady…

  • HELL NO!
    I take serious offense to this. Asperger’s is no excuse for being a killer and people like this are the means by which profiling always starts. I don’t want to be judged and hated by my fellow man for having Asperger’s any more than black people or gays want to be judged for it.

  • I take it this guy couldn’t say he was insane, so he opted for saying he had Asperger’s. But the judge obviously wasn’t buying into it and gave him extra time for thinking he would be stupid enough to go for such an obvious and insincere variation on the insanity defense.

    If you’re gonna tell a judge that he should take it easy on you ’cause you’re touched in the head, you should at least be crazy enough to act touched in the head in front of the judge during your trial.

  • Man fuck that shit, I say put that son of a bitch on the electric chair and let his ass fry to death. That motherfucker wasted 30+ years as a recluse reject despite his mental condition and to matters worse, his own sister had to take care of his ass for those same amount of years, making her suffer and putting her through life’s sacrifices just so she can nurture the fool. And after all that shit, what does she get in return? A fucking knife to the back! And the motherfucker doesn’t show any kind of regret or remorse for his actions? Fuck Him!

  • Funny guy, still trying to get away after what he’s done, he’s not even worth being considered a human anymore.

    As always in Japan justice is too lenient, 20 years of prison wouldn’t change his life much from his previous daily life, make him do labor work till the end of his days, maybe he’ll get to experience a fraction of his sister’s suffering…

  • I have Asperger’s, and you won’t see me brutally killing my family…

    Through my life, me and my parents occasionally faced bias because of retards like this unemployed pathetic fuck doing stupid things and blaming it on Asperger’s.

    Next you’ll see someone blaming a murder on his cold…

    • My brother had Asperger’s too. It doesn’t do anything to cause someone to kill their families. It’s just another person trying to use legitimate conditions as an excuse for their crimes. If you ask me, I don’t give a damn what mental illness or condition you have or claim to have. If you kill someone, you should just get killed right back.

      Besides, if that really is your excuse to commit murder, isn’t that even more of a reason to not reduce their sentence? Wouldn’t that mean that they just might do it again with that as their excuse again?

        • I don’t believe autism-range disorders are caused by genetics. There are plenty of studies that link nutritional deficiencies in the mother during the first weeks pregnancy as a major factor in the development of these disorders. It has also been suggested that mercury poisoning can play a role in increased risk of development even after the child is born.

        • I didn’t say that Aspergers had a ‘cure’. I was saying that because of the way that Asperger’s works, in the more severe cases it has a habit of leaving people open to mental illness.

        • Autism is not a mental illness. It’s predominately genetic. There is no “cure”. “Mild” is also… a bad way of putting things. There is no set line where you’re considered to have it. People like to call it “mild Autism” because the outward appearance makes it look like there are no problems and the brain is generally a bit higher functioning, but it’s Autism all the same.

          Just figured I’d point that out.

          Certain life conditions and situations caused as a result of someone having Autism might make them [theoretically] somewhat more likely to suffer certain mental illnesses, yes, but I’ve never heard of any case where it led to aggressive behaviour or violent crime.

          The Autistic mind is actually quite an organized one. It thrives on structure. Think of it as a PC running on a different chipset and processor. There’s nothing inherently wrong with it. It’s just different. Unfortunately is difficult to make compatible with most “PCs” (society) and few people really understand it.

          So basically Autism is the Macs of the 90s. …Kidding. Sorta.

  • As someone who has Asperger’s Syndrome myself, this is total bullshit. Asperger’s is a social disorder, but it in no way can lead you to doing things like this, if someone has Asperger’s and does something like this, it is their own fault along with anyone who had the opportunity to educate them and missed that chance. I have both Asperger’s and High Functioning Autism, sure, I am on the higher end of the spectrum, I have known a number of people who have had it really bad, all over the charts. Blaming Asperger’s for murdering your imouto is like blaming a math class being to difficult and indiscriminately attacking people in the street.

      • lol

        The default method of fixing anything seems to be to fill people up with drugs.

        People who blame Asperger’s for their commiting of criminal acts are the worst, because it creates stigma around those who actually have the disorder. This guy was clearly weak minded and couldn’t control his own tendancies so he should be locked away for 20 years as he is a danger to society.

        PS: Fellow sufferer here and I haven’t killed anyone yet.

    • Also have Asperger’s. That itself is no reason for anyone to commit murder, and people with Asperger’s may actually be far less likely to intentionally break the law than normal people.
      Having any mental condition is difficult though and having them untreated is more likely to end badly.
      So to kill his sister he would have had to be in a very bad mental state. The two big offenders though are probably 1) lack of mental health support. I don’t know what the state of this is in Japan but I get the feeling finding help is very difficult, and 2) the cultural/social stigma of mental conditions, such that keeping someone hidden (as hikikomori) is seen as a reasonable option instead of having the “shame” of asking for help that the person really needs.
      He should fully get the punishment, but he should also get counselling while in prison, or that prison sentence is likely to be a death sentence for someone with Asperger’s (aka suicide). However the government should also look to itself, and see how it can prevent and help hikikomori and reduce the social stigma of getting help for mental health problems, so something like this doesn’t happen again.

      • I often hear psychologists talk of this social stigma as if it was a factor in them not getting enough clients. There are more important matters, however. It would suffice for him to be depressed to be simply unable to force his body to comply with the rigors of a help-seeking venture. And no welfare means no insurance means expenses.

    • Actually, yes, it can. Asperger’s is something I too have and it has been known to morph into full-blown mental illness because of the lack of human contact that is associated with it.

      • With the right medical assistance, the condition can be managed. I speak from experience as I too have Asperger’s, but with help from my family and doctors I am able to live a relatively normal life. However, a kid I knew in school had the same condition and was left untreated (due to lack of understanding of the condition), resulting in him becoming full-blown schitzophrenic (my worst fear, I might add).

      • It can make one more susceptible to certain kinds of mental illness, yes. There’s no real scientific evidence of anything being “caused” by Asperger’s because societal ignorance puts persons with at a massive predisposition toward things like depression, bipolar disorder, agoraphobia, etc. … This is from research, talk, and dealing with myself on a day-to-day basis.

        This story is bullshit, though. By definition Asperger’s is not a mental illness, for starters. Calling it as such is downright insulting. It’s not something you can treat with a pill or that has a “cure”. You can mitigate its impact on one’s life as much as possible, and nothing more. This is why it’s considered a disability in many cases.

        That, and persons with Asperger’s are more likely to have a refined sense of justice, even if their view on “right and wrong” and the definition of a victim can be a bit hazy at times. Aggression is very rare, and I can’t think of any previous cases of anyone trying to “blame” a murder on Autism. It’s nauseating to try to do so. And, so, yeah, it’s total bullshit. Lock this man away, please.

    • Just a heads up, Imouto means little sister, in this case it was the older sister that was murdered, so it’s “Ane” “Oneesan” not Imouto. I just don’t want people to be mis-informed if they’re going to use Japanese words, please use them correctly.

      p.s I’m Japanese, not some weeaboo trying to correct people.

    • Problem is Japan’s culture is very flawed. Legal child porn, suppression of emotions, most of them are a bunch of beta males. Japan is just a really screwed up country. Sadly it won’t get better because they like to cover up these truth with fake kindess and smiles.

      • @07:45 Yes, Japan’s culture is flawed. They should learn to be like America, so people can run around movie theaters gunning people down.

        Child pornography is NOT legal in Japan.

        Yeah, they should go around suppressing the sexual urges of normal adults, like in America, cause that is working so well.

        • You should really not jump to conclusions about the things you see on the news in the US.
          There is tons of evidence that points to the “batman killer” being a patsy in a staged domestic terror event to further anti-gun legislation. The UN is trying to disarm the world and this was just what they needed to get people against guns so they can pass their gun registration treaty which will eventually lead to gun confiscation.
          Yes people died, and it was an ugly event, but don’t blame our society. Blame the criminals running our governments.

  • Being someone with aspergers, I’m happy that the judge didn’t let him off easy because of it. Too many people happy to do the wrong thing and then blame it on diseases. Sure, don’t throw them in prison if you must, but lock them up in a strait jacket instead then. See if they like that for the rest of their lives.

  • I was going to post the usual I hope he enjoys his sodomy but then I noticed the numbers.
    30 years as a hikikomori and he’s 42 this means it started when he was 12 what kind fucked up do things have to be for a 12 year old to become a hikikomori?
    What he has is not aspergers but most likely some form of schizophrenia.

    There is something very wrong with the diagnosis and treatment of mental health in Japan this should have never been allowed to go on that long and intervention should have happen 30 years ago.

  • That’s still unacceptable, killing your sister after taking care of your for 30 years is just pure unjustified bullshit. Asperger’s syndrome my ass, it mainly just makes you unsociable, and there’s no reason to kill your sister over it.

    Then again, maybe I’m just biased towards this guy because my little sister is gone too.

    • you can feel sorry if want. but there are far worst articles bout this subject. think they have them on here somehwere. Think one of them nearly kille dthe whole family becuase they cut him off from the internet or credit card usage. The mother of another jumpe dout of a 3rd or 2nd story building to escape from being stabbed to death.

    • “The accused has displayed insufficient remorse for his crime”

      One of the main effects of Aspergers is a lack of emotional comprehension and the ability to feel sympathy for others.

      Just because you feel that his condition is relevant, doesn’t mean it wasn’t a factor in this incident.

      No matter how long he is imprisoned for, or if your wishes for blood thirsty revenge are taken into consideration, his sister is never coming back.

      • Asperger’s is called a ‘high functioning’ mental illness and is sometimes not even recognized by certain professionals for a reason. That is, it doesn’t impair your judgment nearly as much as you make it sound. They are not mentally retarded. They are quite aware of something so basic as killing people is wrong (at least as far as civilized society is concerned) and that there are consequences for it. You are basically insulting everyone else who have properly diagnosed Aspergers. Shame. This asshole has no right or basis to ‘hide’ behind Aspergers and demand a free get out of jail card.

        • I don’t think it would be an exaggeration to say that this guy makes all the other people genuinely diagnosed with Aspergers look bad.

          It’s like using “Autism” as a defense online, it shouldn’t work like that.

        • I know a good many people who suffer Aspergers (hell, I myself do) and I can tell you it works nothing of the sort. Asperger blocks or redirects a good bunch of basic emotions, causing those suffering it to appear “weird” or “strange” to others because they cannot feel quite the right way, if there is such a thing. Complex emotions often are not processed/understoof at all. This creates some unusual behaviours and makes other people less likely to talk with them, causing unsocialisation. In more severe cases sufferers of Asperger become depressed because of that.

          There is however absolutely no way that Asperger causes a total emotional deafness and claiming that it’s responsible for a person to kill someone because they simply don’t feel anything due to it is an outright lie.

    • It’s a slippery slope.
      His actions are his own, and certainly he should be punished for them.
      But the condition isn’t his fault.

      If I had to break it down, I’d suggest that while autism doesn’t provide an alibi, it does provide a motive. He should blame himself for what he did, not what he is.

  • The article didn’t have much to say about his motive. Why exactly did he blame her? What was she doing to him that would justify his belief she stunted his chances of separating from her? What happened on the day of her death? Whence the tension? As such, all the attention goes to the justification of the verdict, which is scary and illogical. In context, calling upon the remorse factor tells you the judges, for whatever reason, didn’t even try to understand the situation, and I see no remorse in the explanation of their own contribution to the matter, e.g. basing their verdicts on a family popularity poll. The family backdrop tells you that he effectively decided to get rid of his – as they claim – sole source of income. So there were matters (subjectively) more important than that the day the murder took place. What were they?

    • That’s just the problem, the sister wasn’t doing him any favors, people like that are called enablers.

      If he hadn’t been supported, he would have been forced to find a job and interact with real life.

      • She may have been enabling his hikikomorism but that doesn’t justify killing her. The proper way to deal with the situation would’ve been more along the lines of him saying “hey, sis, you’re an enabler, cut it out and help me get some work instead” or somesuch.

      • Your last sentence is just you pretending to know what you’re talking about, when you don’t have a fucking clue. I mean, we won’t be needing cops in the first place if everyone is psychic.

      • Too shallow. If it was that simple, there would be less posters on sankaku. And, his full social condition unknown, there’s no talking of him being ‘forced’, because it may turn out to be like trying to run off a broken leg.

        Something’s been preventing him from escaping the position that was wearing him down, apparently, if it ended as it did. But nobody cared till somebody died again.

        • What I noticed is he become a hiki at 12.

          Shouldn’t some sorta of social services intervened at that stage when he disappeared from school?

          Yes the US has it’s flaws but if a 12 year old stops showing up at a school and locks themselves in their room it is something of concern and the government will intervene if necessary.

          I think this is just the latest symptom in a broken system that offers little to no help for mental illness as this seems to happen a little to often in Japan.

  • I’m an Aspie.

    And I don’t think it’s inherently right to kill a human being under any circumstances. It’s no calculus.

    Then again, was the guy diagnosed as an Aspie by PROFESSIONALS?

    • There are 36.6 reasons why one shouldn’t even think about the last part.

      The maximum term here is 20 years, so I expect some mitigating circumstances (presence of affect?) are already taken account of. But the intent displayed in the explanations is very disturbing, and yet the defence opted to try the illness plea. A game of cops and robbers on the part of the defendant? Or all in a day’s work for the jury? He probably should go to jail, maybe even for 20 years. But not by means of such a poorly justified verdict.

      • Well, I mentioned the last part because a lot of people like to bullshit with Aspergers. There are still too many people who proclaim themselves as Aspies after only a few readings and some questionnaires. This syndrome doesn’t work that way; it needs to be diagnosed by professionals who know what they do.

        Still, I need to re-iterate that a person being an Aspie should not EVER be grounds for a plea. That’s like claiming that everyone with ADD is prone to murder. These are high functioning psychological problems that are not as extreme as, say, schizophrenia.

        • The wording of this article is a little unnerving near the end, even though it may be out of entirely good intentions. Don’t let it make you feel bad.

          AS doesn’t make you predisposed to be a murderer just as water being present in cancer cells doesn’t make it generally oncogenic. AS may count as a behavior modifier, or something that invites an unusual reaction to it, that could in turn meet with a counter – and such technicalities are in principle important to the judgment process. We don’t know the details here, but it appears unlikely that it was a factor in this case, they knew each other well. He was also unsympathetic toward her lot, that tells you it wasn’t entirely on impulse. So it’s not the sickness part, it’s the situation part that matters.

          On a side note, while one condition does not preclude another, from the point of view of a suffering person, the clinical classification of what is going on with him is not of prime importance. This guy wasn’t on welfare and couldn’t work either, so it may tell you something was on that prevented him from seeking help.

  • I just want to rape my sister again. but now that she is getting into the two digets I fear I wasted a long part of her early life and she is getting aware of what was going on. fuck my shyness.
