Miyazaki was arrested in [[Hachiōji]] in July 1989 after being confronted while taking nude photographs of a young girl. He was diagnosed as having one or more [[personality disorder]]s, but was determined by authorities to be sane and aware of his crimes and their consequences. Miyazaki was [[Capital punishment in Japan|sentenced to death]] in 1997 and was executed by [[hanging]] in 2008.<ref>{{Cite web|last=Matsutani|first=Minoru|date=2008-06-18|title=Serial killer Miyazaki, two others hanged|url=https://www.japantimes.co.jp/news/2008/06/18/national/serial-killer-miyazaki-two-others-hanged/|access-date=2021-04-02|website=The Japan Times|language=en-US|archive-date=2022-07-10|archive-url=https://web.archive.org/web/20220710202513/https://www.japantimes.co.jp/news/2008/06/18/national/serial-killer-miyazaki-two-others-hanged/|url-status=live}}</ref><ref>{{Cite web|title=Nerd cult murderer executed|url=https://www.telegraph.co.uk/news/worldnews/asia/japan/2144503/Nerd-cult-murderer-executed.html|access-date=2021-04-02|website=The Telegraph|date=16 June 2008|language=en-GB|archive-date=2022-07-10|archive-url=https://web.archive.org/web/20220710202735/https://www.telegraph.co.uk/news/worldnews/asia/japan/2144503/Nerd-cult-murderer-executed.html|url-status=live}}</ref>

Miyazaki was dubbed the "'''Otaku Murderer'''" due to his extensive collection of [[anime]], [[manga]], [[horror fiction|horror]] videotapes and [[hentai]] as well as various other forms of [[pornography]]. This triggered a widespread [[moral panic]] against ''[[otaku]]'' in Japan, similar to the [[Satanic Panic]] in America.<ref>{{cite book |title=Otaku and the Struggle for Imagination in Japan |last=Galbraith |first=Patrick W. |url=https://books.google.com/books?id=0d28DwAAQBAJ |location=Durham |publisher=Duke University Press |year=2019 |isbn=978-1-4780-0509-4 |jstor=j.ctv1220mhm |oclc=1148100778 |pages=67–68|doi=10.2307/j.ctv1220mhm }}</ref>

==Early life==
Tsutomu Miyazaki was born on 21 August 1962 in [[Itsukaichi, Tokyo]], the son of a wealthy family. He was [[premature birth|born premature]] and had the rare birth defect [[radioulnar synostosis]] that caused his hand joints to be fused together, making him unable to bend his wrists upwards.<ref name=charlest>{{cite web|url=http://www.charlest.whipple.net/miyazaki.html|title=The Silencing of the Lambs|author=Charles T. Whipple|access-date=5 March 2008|archive-url=https://web.archive.org/web/20070818192957/http://www.charlest.whipple.net/miyazaki.html|archive-date=18 August 2007}}</ref>{{unreliablesource|date=June 2025}} Miyazaki's family operated a regional newspaper company and were well known in Itsukaichi, where his grandfather and great-grandfather had served on the town council. Due to his parents being busy, he was mainly raised by his grandfather and an [[intellectually disabled]] man the family hired as a nanny.

Miyazaki was ostracized when he attended elementary school due to his deformity, and consequently kept to himself. He attended {{ill|Meiji Nakano High School and Junior High School|lt=Meidai Nakano High School|ja|明治大学付属中野中学校・高等学校}} in [[Nakano, Tokyo|Nakano]], a prestigious high school associated with [[Meiji University]], and was a star student until his grades began to drop dramatically. He was ranked 40 out of 56 in his class and did not receive the customary admission to Meiji University for students of the school. Instead of studying English and becoming a teacher as he originally intended, Miyazaki attended a local junior college and studied to become a photography technician.<ref name=charlest/>{{unreliablesource|date=June 2025}}

In the mid-1980s, Miyazaki moved back into his parents' house in Itsukaichi, sharing a room with his elder sister. Although his family was highly influential in Itsukaichi, he expressed no desire to take over their business. After his arrest, Miyazaki would say that what he really craved was "being listened to about his problems" but believed that his parents, more worried about the material than the sentimental, "would have not heard [him]; [he] would've been ignored".<ref name=lyon>{{cite book|author1=Lyon, Samantha |author2=Daphne Tan |title=Supernatural Serial Killers: What makes them murder?|publisher=Arcturus Publishing|year=2015|isbn=978-1784281328}}</ref> In the same confession, he said that by this period in his life he had begun to [[suicidal ideation|consider suicide]]. Miyazaki felt he only received support from his grandfather, to whom he was close, and was rejected by his two younger sisters.

In May 1988, Miyazaki's grandfather died, which served to deepen his [[major depressive disorder|depression]] and isolate him even further.<ref name=lyon/> In an attempt to "retain something from him", Miyazaki ate part of his grandfather's ashes. A few weeks later, one of Miyazaki's sisters caught him watching her while she was taking a shower; he attacked her when she told him to leave. When his mother learned of the incident and demanded that he spend more time working and less time with his [[videotape]]s, he attacked her as well.<ref name=lyon/>

==Murders==
Between August 1988 and June 1989, Miyazaki mutilated and murdered four girls between the ages of 4 and 7, and [[necrophilia|sexually molested their corpses]]. He drank the blood of one victim and ate a part of her hand.<ref>{{cite news|url=https://www.scotsman.com/news-2-15012/serial-child-killer-hanged-as-japan-steps-up-death-penalty-1-1173292|title=Serial child-killer hanged as Japan steps up death penalty|work=[[The Scotsman]]|location=Edinburgh|date=17 June 2008|access-date=9 May 2019|archive-date=6 February 2020|archive-url=https://web.archive.org/web/20200206221104/https://www.scotsman.com/news-2-15012/serial-child-killer-hanged-as-japan-steps-up-death-penalty-1-1173292|url-status=live}}</ref> These crimes—which prior to Miyazaki's apprehension were named the "Little Girl Murders" and later the {{nihongo|Tokyo/Saitama Serial Kidnapping Murders of Little Girls|東京・埼玉連続幼女誘拐殺人事件|Tōkyō Saitama renzoku yōjo yūkai satsujin jiken}}—shocked [[Saitama Prefecture]], which had few crimes against children.

On 22 August 1988, one day after Miyazaki's 26th birthday, Mari Konno, aged 4, vanished while playing at a friend's house. Miyazaki had led Konno into his black [[Nissan Langley]], then drove westward of Tokyo and parked the car under a bridge in a wooded area. There, he sat alongside Konno for half an hour before murdering her and molesting her corpse. He dumped her body in the hills near his home, departing with her clothes, then allowed the body to [[human decomposition|decompose]] before returning to remove her hands and feet, which he kept in his closet. Miyazaki burned Konno's remaining bones in his furnace, ground them into powder, and sent them to her family in a box along with several of her teeth, photos of her clothes, and a postcard which read, {{lang|ja|「真理さん、骨、火葬、調査して、証明して」}} ("Mari. Bones. Cremated. Investigate. Prove.")<ref>{{cite book|last=McQueen|first=Victor|title=The World's Worst Serial Killers: Monsters whose crimes shocked the world|publisher=Arcturus Publishing|year=2015|isbn=978-1784281489}}</ref> Konno's hands and feet were found in Miyazaki's closet after his arrest almost a year later.

On 3 October 1988, Miyazaki abducted Masami Yoshizawa, aged 7, after spotting her while driving along a rural road. He had offered Yoshizawa a ride, which she accepted, then drove her to the same place he had killed Konno. Miyazaki killed Yoshizawa, engaged in sexual acts with her corpse, and took her clothes with him when he departed.<ref name=keller>{{cite book|last=Keller|first=Robert|title=Beyond Evil|year=2016|publisher=Robert Keller |isbn=978-1536507645}}</ref> Two months later, on 12 December 1988, he abducted Erika Namba, aged 4, as she was returning home from a friend's house. Miyazaki forced her into his car and drove to a parking lot in [[Naguri, Saitama|Naguri]], where he forced her to remove her clothes in the back seat and began to take pictures of her. He killed Namba, tied her hands and feet behind her back, covered her with a bedsheet, and placed her body in his car's trunk. He disposed of her clothes in a wooded area and left her body in the adjoining parking lot, where it was discovered three days later. On 20 December, Namba's family received a postcard sent by Miyazaki with a message assembled using words cut out of magazines: {{lang|ja|「絵梨香、かぜ、せき、のど、楽、死 」}} ("Erika. Cold. Cough. Throat. Rest. Death.")<ref name=keller/>

On 6 June 1989, Miyazaki convinced Ayako Nomoto, aged 5, to allow him to take pictures of her. He then led Nomoto into his car and murdered her, covered her corpse with a bedsheet and placed her in his trunk. Miyazaki took the corpse into his apartment and spent the next two days engaging in sexual acts with her body, taking photos and videos of the remains in various positions.<ref name=keller/> When Nomoto's corpse began to decompose, Miyazaki [[dismemberment|dismembered]] it, abandoning her torso in a cemetery and her head in the nearby hills. He kept her hands, drinking blood from and [[Human cannibalism|cannibalizing]] them. Fearing that the police would find Nomoto's body parts, Miyazaki returned to the cemetery and the hills two weeks later and carried the remains back to his apartment, where he hid them in his closet.<ref>{{Cite book |first=Mitzi |last=Szereto |title=The Best New True Crime Stories : Serial Killers. |date=2019 |publisher=Mango Media |isbn=978-1-64250-073-8 |oclc=1124612404}}</ref>

==Arrest==
On 23 July 1989, Miyazaki saw two sisters playing in a park in [[Hachiōji]] and managed to separate the younger of the sisters from the older one, who stayed behind. He was taking photographs of the younger one, whom he had convinced to strip nude, when he was caught by their father, who attacked Miyazaki but was unable to restrain him.<ref>{{cite news| url = https://www.abc.net.au/news/2008-06-18/japan-confirms-execution-of-cannibal-killer/2475810| title = Japan confirms execution of cannibal killer - ABC News| newspaper = ABC News| date = 18 June 2008| access-date = 2019-05-08| archive-date = 2022-07-10| archive-url = https://web.archive.org/web/20220710202001/https://www.abc.net.au/news/2008-06-18/japan-confirms-execution-of-cannibal-killer/2475810| url-status = live}}</ref><ref name=keller /> After fleeing on foot, Miyazaki eventually returned to the park to retrieve his car, whereupon he was arrested by police responding to a call by the father. A search of his two-room [[bungalow]] produced 5,763 videotapes, some containing [[anime]] and [[slasher film]]s (later used as reasoning for his crimes). Interspersed among them was video footage and photos of his victims. Miyazaki, who retained a perpetually calm and collected demeanor during his trial, appeared indifferent to his capture.<ref>{{cite news|author=Schoenberger, Karl|url=https://www.latimes.com/archives/la-xpm-1989-09-09-mn-1579-story.html|title=Sordid Serial-Killing Case Exposes the Other Side of Innocence in Japan|work=[[Los Angeles Times]]|date=9 September 1989|access-date=2019-05-08|archive-date=2022-07-10|archive-url=https://web.archive.org/web/20220710203545/https://www.latimes.com/archives/la-xpm-1989-09-09-mn-1579-story.html|url-status=live}}</ref>

==Moral panic==
Japanese media dubbed Miyazaki the "Otaku Murderer", in reference to ''[[otaku]]'' culture.<ref>{{cite web|url=http://scaredyet.net/the-otaku-killer-miyazaki-tsutomu/|title=The Otaku Killer: Miyazaki Tsutomu|author=Oliviera, James|date=3 January 2010|access-date=7 January 2015|archive-url=https://web.archive.org/web/20150107074646/http://scaredyet.net/the-otaku-killer-miyazaki-tsutomu/|archive-date=7 January 2015|url-status=live}}</ref>{{Better source needed|reason=Citation is the scaredyet website; which has not referenced the sources for the claims|date=April 2021}} His killings caused a [[moral panic]] against ''otaku'', with speculation that anime and horror films had made him a murderer. Various newspapers claimed that Miyazaki had retreated into a fantasy world of manga as a result of his neglected upbringing.<ref name=Kinsella>{{cite journal|last=Kinsella|first=Sharon|year=1998|title=Amateur Manga Subculture and the Otaku Panic|journal=Journal of Japanese Studies|volume=24|issue=2|pages=308–9|url=http://www.kinsellaresearch.com/new/Japanese%20Subculture.pdf|publisher=Washington University Press|doi=10.2307/133236|jstor=133236|access-date=2019-06-29|archive-date=2021-01-23|archive-url=https://web.archive.org/web/20210123000316/http://www.kinsellaresearch.com/new/Japanese%20Subculture.pdf|url-status=live}}</ref>{{Better source needed|reason=No mention of Miyazaki in the journal|date=April 2021}}
Keigo Okonogi, a [[psychoanalyst]] at [[Tokyo International University]], told the ''Shūkan Post'' that:

{{blockquote |text=
The danger of a whole generation of youth who do not even experience the most primary two- or three-way relationship between themselves and their mother and father, and who cannot make the transition from a fantasy world of videos and manga to reality, is now extreme.<ref name=Kinsella/>
}}

These reports were disputed. In [[Eiji Ōtsuka]]'s book on Miyazaki's crimes, he argued that Miyazaki's collection of pornography was probably added or amended by a photographer in order to highlight his perversity.<ref>{{cite web|url=http://www1.odn.ne.jp/kamiya-ta/gisi.html|script-title=ja:大塚英志『「おたく」の精神史』～ぼくが中学時代につくった「偽史」について|trans-title=Hideshi Otsuka "Psychical History of Otaku"-"About the "fake history" I made during junior high school"|language=ja|author=Kousetsu Kamiya|access-date=9 May 2019|archive-date=10 July 2022|archive-url=https://web.archive.org/web/20220710205527/http://www1.odn.ne.jp/kamiya-ta/gisi.html|url-status=live}}</ref> Another critic, Fumiya Ichihashi, suspected the released information played up to public [[stereotype]]s and fears about ''otaku'', as the police knew they would help cement a conviction.<ref>{{cite web|url=http://www.sunfield.ne.jp/~mike/books/nonfiction/crime/author/ichihashi_fumiya/miyazaki.htm|title=Miyazaki Tsutomu Jiken|publisher=Japanese Literature Webring|access-date=9 May 2019|archive-date=25 May 2012|archive-url=https://archive.today/20120525194740/http://www.sunfield.ne.jp/~mike/books/nonfiction/crime/author/ichihashi_fumiya/miyazaki.htm|url-status=live}}</ref> Sharon Kinsella asserts that large collections of manga and videos were typical in the rooms of youths living in the Tokyo area at the time.<ref name=Kinsella/>

==Trial and execution==
Miyazaki's trial began on 30 March 1990. Often talking nonsensically, he blamed his actions on "Rat Man", an [[alter ego]] who he claimed forced him to kill; he spent time during the trial drawing "Rat Man" in cartoon form.<ref>{{cite news |url=http://www.timesonline.co.uk/tol/news/world/asia/article4156285.ece|title=Japanese 'cannibal killer' executed in Tokyo |work=[[The Times]]|date=17 June 2008|access-date=17 June 2008|location=London|author=Lewis, Leo|archive-url=https://web.archive.org/web/20110814141434/http://www.timesonline.co.uk/tol/news/world/asia/article4156285.ece |archive-date=14 August 2011|url-status=dead}}</ref> 

The seven-year trial focused on Miyazaki's mental state at the time of the murders. Under Japanese law, people of unsound minds are not subject to punishment, and people having cognitive disability are entitled to reduced sentences. Three teams of court-appointed expert psychiatrists came to differing conclusions about Miyazaki's ability to tell right from wrong: one team determined Miyazaki to have a cognitive disability, another team thought him either [[schizophrenia|schizophrenic]] or as having [[dissociative personality disorder]] (also known as "multiple personality disorder"), and the third team found that although Miyazaki definitely had at least one [[personality disorder]], he was still capable of taking responsibility for his actions.<ref name="JapanTimes1997-04-14">{{cite news |title=Serial child-killer Miyazaki gets death sentence |url=https://www.japantimes.co.jp/news/1997/04/14/national/serial-child-killer-miyazaki-gets-death-sentence/ |access-date=27 June 2019 |work=[[The Japan Times]] |date=14 April 1997 |archive-date=10 July 2022 |archive-url=https://web.archive.org/web/20220710205937/https://www.japantimes.co.jp/news/1997/04/14/national/serial-child-killer-miyazaki-gets-death-sentence/ |url-status=live}}</ref>

The [[Tokyo District Court]] judged Miyazaki aware of the magnitude and consequences of his crimes and therefore accountable. He was [[Capital punishment in Japan|sentenced to death]] on April 14, 1997.<ref name="JapanTimes1997-04-14"/> His death sentence was upheld by both the [[Tokyo High Court]], on June 28, 2001, and the [[Supreme Court of Japan|Supreme Court of Justice]] on January 17, 2006.<ref>{{cite news|url=http://english.people.com.cn/200601/17/eng20060117_236139.html|title=Japan's Supreme Court upholds death penalty on child killer|work=[[People's Daily]]|location=Beijing|agency=[[Xinhua]]|date=17 January 2006|access-date=9 May 2019|archive-date=25 December 2007|archive-url=https://web.archive.org/web/20071225114110/http://english.people.com.cn/200601/17/eng20060117_236139.html|url-status=live}}</ref>
