Takuma Mamoru, November 23, 1963 – September 14,
2004) was a Japanese janitor who committed mass
murder of 8 people and wounded 15 others in the 2001
Osaka school massacre. He had been convicted and
imprisoned for rape before the massacre.
Takuma dropped out of high school and
was disowned by his father. He entered the Japan Air
Self Defense Force but was soon discharged due to having
sexual intercourse with a minor. In 1984, Takuma lived
with his mother secretly. His father was very angry and
took back his wife.
In November 1984, he was arrested for
raping a woman and sentenced to three years in prison.
He had been arrested at least eleven times and had
married four times before the massacre. After his
release from jail, he moved to Ikeda and found work as a
bus and garbage truck driver. He was described by
coworkers as a quiet and unremarkable man, but a bit of
a loner who did not like dealing with customers and
preferred working alone.
After assaulting a passenger over the
smell of her perfume in 1998, he was fired and got a new
job as maintenance man at Itami Elementary School, 6
kilometers away from Ikeda. In October of the same year,
he was arrested on suspicion of assaulting his former
On March 3, 1999, he dissolved some
of his own tranquilizer, temazepam, into the tea served
in the teachers' room, sending 4 people to the hospital.
He was arrested and sent to a psychiatric hospital,
where he was diagnosed with schizophrenia, but after one
month's treatment was judged to be "capable of taking
care of himself" and released.
In November 1999, he
was arrested on suspicion of entering into a private
home, but charges were dropped. He managed to get a job
as a taxi driver in September 2000, but was fired on
October 16th after he assaulted a hotel bellhop in Osaka
and broke his nose. He was also kicked out of several
apartments for, among other things, throwing his garbage
out from the balcony. On May 23, 2001, he was again
committed to the hospital, but he left after one day and
did not return.
On June 8, 2001, the day of his court
hearing for the bellboy assault case, he went on a
murderous rampage in the Ikeda Elementary School.
Wrestled down by staff within minutes, he was described
as being in an extremely confused state when arrested,
at first repeating "I went to the elementary school",
and then saying "I went to the train station and stabbed
100 people with my knife. I did not go to the elementary
He also stated:
Nani mo kamo iya ni natta.
Nankai mo jisatsu wo hakatta ga shi ni kirenai.
Tsukamaete shikei ni shite hoshikatta.
"I've become disgusted with
everything. I've tried to kill myself several times,
but couldn't. Give me a death sentence."
Takuma also hated
"elite" children, who attended the school he attacked.

Trial and death
He seemed to be regarded as insane at
first, but his illness was eventually diagnosed as
paranoid personality disorder, borderline personality
disorder and antisocial personality disorder. At first,
he claimed that he took a 10× overdose of his
psychiatric drugs on the day, but medical analysis found
no trace of them in his body. His psychiatrist denied
that he suffered from schizophrenia.
On August 28, 2003, Takuma was found
guilty of multiple counts of murder and sentenced to
death. He was ejected from the court before the sentence
because he continued to verbally insult the victims and
the victims' parents. Takuma remained unrepentant,
refusing to apologize to the families of the victims,
and only asked for the sentence to be fulfilled as fast
as possible. His statement was, "I should have used
gasoline, so I could have killed more than I did."
Takuma insisted his execution to take place as soon as
possible. The sentence was carried out with unusual
speed, and Takuma was executed by hanging on September
He has had an influence on Japanese
murderers. For example, Kaoru Kobayashi, who had
sexually assaulted and murdered seven-year-old girl
Kaede Ariyama, considered Takuma as a charismatic
murderer and sought speedy execution.

police and rushed the children out to the playground.
Within minutes after the attack, a

a history of schizophrenia, but psychiatrists reportedly determined he
could tell right from wrong and was fit to stand trial. The attack led
to calls for greater security at schools. Takuma allegedly entered the
school unopposed and went from classroom to classroom knifing children.
Osaka school killer says he targeted elite kids
OSAKA -- A school mass murderer said Thursday that he fatally stabbed
his victims last year because he wanted the public to know that even the
"clever children of rich families" can instantly be murdered.
Mamoru Takuma, 38, is standing trial for killing eight
children in June last year at Ikeda Elementary School in Osaka
Takuma admitted he targeted the school, attached to
Osaka Kyoiku University, because of its elite status.
"I had a variety of reasons for targeting the
school," he told a hearing at the Osaka District Court on Thursday.
"One of them is that I wanted the public to know that even clever
children of wealthy families can be killed in five or six seconds."
In describing his motives, Takuma mentioned his hate
of a society that places too much emphasis on education.
"I don't think scholastic studies are everything
in the world," he said.
Days after the brutal attack, Takuma said he targeted
the school out of "envy at elite people."
Takuma said that he also planned to attack a woman's
high school with a gun and ram a truck into a shopping street.
He added that he decided the day before to attack the
school and can't recall exactly what happened.
"I don't remember how many children I
stabbed," he said.

Justice served in
On June 8, 2001, a disgruntled jobless man stormed into an Osaka
elementary school, wielding a kitchen knife, and killed eight children
and wounded 13 others and two teachers. "This is an unprecedented case
of atrocity in the nation's criminal history," the Osaka District Court
stated in its death sentence Aug. 28. "The grief and anger of the
bereaved families is profound. There is no alternative but the death
penalty." It is impossible to argue against this ruling.
20-month trial, Mamoru Takuma, 39, showed himself to be a coldblooded
man with a twisted mentality. He showed no signs of remorse for the
murders. He hurled insults at relatives of the victims. He showed
contempt for the court. And he effectively boycotted the session Aug.

"Let me say my
last words. I'm going to die anyway." The presiding judge refused to
listen and ordered the defendant to be removed from the courtroom. That
was the right decision. Yet it was extremely unusual and very
unfortunate that the ruling was handed down without the presence of the
Takuma has only
himself to blame. During the trial he was offered a chance to state his
view again and again, yet each time he refused to speak presumably
because he did not want to reveal his "weaknesses." Indeed, it is likely
that he was afraid to listen to his death sentence.
The saving grace
is that he admitted all charges, though it remains unclear why he acted
as he did. The trial focused on the question of whether he was sane
enough to tell right from wrong. The court has reasonably concluded that
he was, citing what it calls "highly credible" psychiatric evaluations.
"The case reveals a self-centered and exceedingly distorted
personality," the ruling states. "He showed no effects of any mental
illness and therefore possessed sufficient mental capacity to be held
criminally responsible for his actions."
The Takuma case
has turned a spotlight on two major defects in our society: lack of
security at schools and inadequacy of crime-prevention measures for
mentally disabled people.
As for the first
problem, an increasing number of schools have taken a variety of safety
measures, such as setting up alarms against intruders and monitoring
cameras, as well as requiring students to bear name patches on their
uniforms. Many schools have tried to limit contacts with outsiders.
Meanwhile, the education ministry has prepared manuals on crime
prevention and crisis management.
however, it may be difficult to keep out all trespassers at all times.
Perhaps the best deterrent would be to promote residents' participation
in school management or create a self-policing environment with the
cooperation of communities. In that kind of situation it should be
easier to work out more specific safety measures.
second problem, the Diet has passed legislation mandating the medical
observation of mentally ill people who have committed serious offenses.
The law applies to those who, although exempted from prosecution or
declared innocent, have been found by judges and psychiatrists to be
liable to repeat offenses. If so determined, such people may be ordered
to visit or enter hospitals.
That is a step
in the right direction. The question that remains is what to do about
criminals, such as Takuma, who are mentally fit but have serious
personality disorders. As yet there seems to be no adequate measures in
place to deal with such "borderline" offenders. Takuma has admitted
entering a hospital by feigning mental illness. This suggests that the
existing legal system is not perfect. Dealing with cases like Takuma's
requires closer cooperation between psychiatric medicine and criminal
In a nutshell,
the accused comes across as a selfish man trying to shift all his
troubles to other people and to society in general. Yet, on the first
day of the trial, he offered an apology, saying he wanted to "make
amends" by accepting capital punishment. After that, however, he became
defiant and remorseless.
trial has left a soothing precedent for the victims' relatives: for the
first time they were allowed to watch the proceedings via monitors in a
separate room. It was a thoughtful measure to spare family members the
pain of sharing the same space with the defendant. They certainly
deserved such consideration given the beastly crime he had committed.

OSAKA — The Osaka District Court on
Thursday sentenced Mamoru Takuma, 39, to death for
murdering eight children and injuring 13 others and two
teachers in a stabbing rampage with a butcher's knife at
an Osaka elementary school in June 2001.

turned the demand down and ordered him to leave.
Nontheless Takuma made abusive
remarks on bereaved families before leaving.
On June 8, 2001, armed with a
long-bladed kitchen knife he had just bought, Takuma
walked into the elementary school and killed seven girls
and one boy in Ikeda City, some 400 kilometers west of
Thirteen other children and two
teachers were injured. The stabbing shocked Japan,
triggering calls for tighter security in schools.
Takuma pleaded guilty when his trial
opened in December 2001. He has showed no regret over
the crime, saying: "I could have killed more if it had
been at a kindergarten."
The judge ruled Thursday that Takuma
was mentally fit enough to face punishment although he
had been a psychiatric patient formerly diagnosed with
"He has a self-centered, very warped
personality. But there is no influence of any mental
illness and he had sufficient mental competency to be
held responsible for the crime," the judge said.
The judge said the two psychiatric
evaluations that found Takuma to be mentally competent
were "highly dependable." In the mental tests, experts
concluded that Takuma suffers from a personality
disorder but not schizophrenia.
"The defendant was fully aware of the
illegality and gravity of his conduct," the judge said,
describing the crime as "one of the most heinous and
grave cases in Japan's criminal history."

to appeal against the death sentence after consulting
with their client, but Takuma has reportedly told them
that he would withdraw an appeal if they lodged one.

schools in Japan to boost safety measures and led to
legislation authorizing the creation of panels of judges

stabbing prompts debate over treatment of mentally ill
By The Associated Press
July 14, 2001
TOKYO It's any society's nightmare: A man with a history
of schizophrenia and an arrest record is released from a
mental hospital then explodes in a bloody rampage.
That nightmare became reality in Japan last week, when a
former psychiatric patient and crime suspect burst into
an elementary school and slashed eight children to
In the aftermath of the stabbings and a string of other
crimes by psychologically troubled attackers, Japan is
in the thick of a thorny debate: Is the system too
lenient with mentally ill criminals?
"Looking at a crime like this, something has to be
done," said Prime Minister Junichiro Koizumi, who is
pushing to consider toughening the penal code.
Mamoru Takuma, the suspect in last week's stabbings,
apparently fell through the cracks of the Japanese
mental health system.
Takuma, 37, was accused in 1999 of slipping
tranquilizers into the tea of four teachers at the
school where he worked as a janitor. Diagnosed as a
schizophrenic, he was never charged and was sent to a
mental hospital, which later released him.
Since the school attack, news reports have been filled
with accounts of Takuma's other brushes with the law,
including allegations he battered and threatened to kill
Japan's mental health debate so far has focused on
whether to screen psychiatric patients for criminal
tendencies, allow them to be punished under the law or
make it more difficult to win release from mental
Proposals of reform have run into opposition from some
including members of Koizumi's Cabinet who worry that
changing the laws could lead to discrimination against
the mentally ill, who already face a heavy stigma in
"This is an issue we must consider seriously," Justice
Minister Mayumi Moriyama said this week, urging
caution. "We must consider specific ways to effectively
carry out our current laws."
Japanese courts now are remarkably hands off when it
comes to defendants with psychological problems.
The penal code prohibits punishment of the mentally ill,
no matter what the crime, murder included. And once
offenders are committed to a mental hospital, they can
be released at any time without court approval.
Of 3,629 people suspected of mental illness who were
arrested or apprehended from 1995 to 1999, nearly 90
percent 3,240 were never charged. The approximately 10
percent who were ruled competent for trial and who were
eventually convicted received reduced penalties,
according to the Justice Ministry.
That holds up even for the 726 mentally ill suspected of
murder: some 84 percent were never indicted.
The official definition of mentally ill in Japan goes
well beyond strictly psychological problems. Alcoholics,
drug addicts and even epileptics are all largely
protected from prosecution.
Mentally retarded suspects are also in the category, but
the system falls hardest on them. They are prosecuted at
a much higher rate of 42.3 percent.
Instead of prisons, violent offenders are typically
confined in mental hospitals. But there are no
facilities in Japan specifically designed for the
criminally insane, and doctors have no special training
to handle them.
"Psychiatrists are experts in treating the mentally ill,
but they're not experts in criminals," said Yoshiharu
Kim of Japan's National Institute of Mental Health.
"They have zero knowledge about criminals they don't
learn about that in school."
Moves to reform the penal code gained momentum in recent
years, spurred by a rash of crimes by emotionally
troubled juveniles, including a bus hijacking last year
that killed one person. A government panel has been
studying the matter since January.
But the horror of the school stabbings has pushed the
issue to the front burner.
In the attack last Friday, the killer climbed from a
verandah into a first-grade classroom in Ikeda, outside
the city of Osaka, killing eight and wounded 15.
In the aftermath of the killings, attention has focused
on getting the courts involved in deciding on the
release of offenders from mental institutions, rather
than leaving it up to doctors.
But there is also fear that hysteria over the latest
killings could lead people to link mental illness with
illness can attack anyone," warned the Asahi newspaper
in an editorial on Tuesday. "It is wrong to regard all
mentally ill people as a 'reserve army' of criminals."
