Japan - Miyazawa family of 4 murdered, Setagaya, Tokyo, 30 Dec 2000 #4

  • #441
Just a little tidbit of info that I found interesting and others might too.

A Japanese YouTuber got his hands on old maps of Setagaya and the Kamisoshigaya neighbourhood that ranged back from 1980 up until 2000 and discovered that the building directly next to the Miyazawa house on the right was actually student housing during the 80’s and part of the 90’s, and not a house. After the Miyazawa’s and Irie’s moved in during 1990 it then changed into an apartment building that housed several tenants.
Interestingly the house directly to the left of the Miyazawa house had the owner listed with the same surname as the owner listed on the apartment building to the right. It wasn’t confirmed but it’s possible the same person owned both buildings that sandwiched the family house.
Furthermore, due to the walking distance from surrounding train stations and the apartment building likely only having had one-room type apartments for its original purpose of housing students, the YouTuber speculates the rent would have been cheap and likely continued to house either students or mainly young people.

The apartment building was still on the neighbourhood map at the end of 1999 but then was gone by the end of 2000, meaning it was there until perhaps only a half year before the murders.
RSBM:

Interesting info for sure, thanks @Incoherent! What kind of student housing and for who? Locals or international? I'm assuming college aged kids if living alone and not high school (unless from abroad)?

So the family may have lived next door to person(?) possibly up to an almost 10yr span. Maybe their friends came over to hang out. That may be where a grudge, obsession or hyper-focused anger built up if said person was spending lots of time next either living or visiting a pal.

I hope all the students and friends/visitors who lived in the housing were interviewed! MOO

Apologies for the radio silence, thread friends. I promised I'd return with news when/if there was any. As such: an offer has been made from a major audio platform for another Miyazawa murder podcast written / hosted by your humble narrator.

All being well, we should be out in time for the 25th anniversary of the murders.
I'm definitely late to the party, but a big kudos to you! This is great news :)

Regarding the use of DNA in a new development concerning a Japanese woman's murder in Thailand, fwiw..

I don’t really understand why they are focusing on the French person instead of her male Japanese friend who fled the country and refused to provide dna to clear himself.

Just as a side note and not to speak for him, but we should not expect any further information to be given from Nic at all while the podcast is being made to prevent the investigation from being tampered or interfered with. There are unfortunately people out there and on these threads with bad intentions that have already caused problems and had to be dealt with swiftly. By the time the podcast is finished we will have an answer.
Thank you so much for sharing this @Incoherent! It this information was very insightful and for me, it helped me deepen my understanding of the surrounding environment or area in which Miyazawas as I try to picture it.

Also, it made think more Japan in the early 2000s and late 90s when there was growing concern on the uptick of violent juvenile crime. Though I am admittedly learning more about this topic and time period, one theory proposed by WSWJ is that immense pressure from the education system, feelings of isolation from one’s own family and the country’s political system and 1998 having the lowest employment rate for college graduates post-WWII may have contributed to feelings of frustration, rage and distress among the country’s youth that sometimes expressed themselves in acts of uncontrollable rage and violence. Of course, not all the youth in Japan experienced the same responses or expressed themselves as such but it did make think more about the students who potentially lost cheap or affordable housing after their building was torn down in Setagaya Park and perhaps some, or at least one of them, struggling with the same emotions of anger, frustration, disappointment and loss of control or say in their own future or where they can call home. Considering the distress already caused by a lack of job security, possible costly living expenses and their demanding academic responsibilities, perhaps the loss of housing was just too much or could have a played a role in the horrific murders. Perhaps the killer fixated on the Miyazawas because they seemed to be living the dream with a successful couple thriving in their careers, bright and happy kids, a home to still call their own, time to bond and travel around the city and the world and the ability to move to a new home when the time comes. They, IMO, reached a point in their lives that many of us would also like to reach when we are the same age as them and yet perhaps because of the social and economic circumstances at the time it no longer seemed possible. Youth in the US have also experienced similar fears and responses and perhaps, as we have seen sadly also in America, the killer unjustly and brutally displaced or projected all of their resentment, envy, anger and disappointment towards Japan and a system that failed them towards the Miyazawas?

This is just one theory I have had from my reading so far but of course I could be off the mark and nevertheless, even if the killer did feel society or life failed them doesn’t mean justice needs to fail the Miyazawas and their family members. They deserve answers and the killer deserves to be held accountable in the court of law.

JMO/speculation from the helpful info you shared with us. I still have faith that their killer will be caught, especially with all the updates we have received over the past several months

@AppleTreeGreen just on your point about the loss of affordable or low-income housing, I do agree. The maps that pre-date the decision to demolish the surrounding houses and buildings show several apartment buildings that would have contained cheap housing in the neighbourhood due to its distance from the train stations. The proximity of the universities would also indicate that the likelihood of students being in those buildings was high as well as those that couldn’t afford to pay much rent and sought cheaper accommodation.
In fact, one thing that is overlooked for some reason is in the kid’s park behind the house there was still one of those apartment buildings standing when the murders happened. One would assume everyone living in there was grilled to the nth degree though of course. The map I attached is kinda hard to read but there were also 3 further apartment buildings behind the house when the Miyazawa’s moved in.

I’m particularly interested in who lived directly next door in that apartment building as it was still standing in 1999, just a year before it all happened.

Something hopeful that I just noticed about the information you shared with us is that it implies that the likelihood is high that whoever owned or managed the apartments still has some sort of records of the renters, such as their name, age, home address or at least how they paid. If not the owners, perhaps maybe even the school still has some records of the students who resided in that area or in the buildings right before they were torn down?

Additionally, thinking more about the perp being fixated not only on the Miyazawas but their housing as well because of his own loss, I wonder if afterwards the building’s owner, manager or the school can recall any of the previous renters or male students in general inquiring or expressing interest in finding housing in that area again? In particular I wonder if any did so even into the next year and around the time of the murders? I wonder if they recall anyone inquired frequently or repeatedly even despite being told nothing was available repeatedly and just seemed to fixate on that one particular area of Setagaya Park? Or if in retrospect perhaps there were one or two previous residents who not only seemed to unable or unwilling to accept that housing opportunity was gone but also seemed to exhibit much more distress or impairment than the school or the buildings owner had anticipated or from their perception seemed out of proportion compared to what triggered it? Just speculating or wondering out loud on my part.


IIRC, Nic also mentioned the possibility that the culprit was confronted by Yasuko previously because of how close they parked their car. I wonder too if the buildings owners, managers or the school have any records of the residents vehicles or the cars students drove to school and were permitted to park on or near campus? Perhaps those records could be compared too with any description LE was able to glean regarding the vehicle Yasuko had seen? Or perhaps a description of the color or something may help a former resident recall even the slightest detail about a similar vehicle being driven by another renter or that renter’s parents, relatives, friend or partner?

Or perhaps the school kept track of previous renters who had to start driving to school after their building was torn down?

I agree that LE likely did a lot of digging through this data already like you said and I can only imagine what a relief it must have been for them to have additional trains of thoughts that could be ruled in or out as they tried to identify the culprit. I really do admire their diligence in trying to leave no stone unturned as they continue to honorably seek justice for the Miyazawas.

JMO/thinking out loud

Random thoughts - also if any students/young people in that neighborhood at that time were impacted by the housing situation, would there be a reason to blame the family for something linked to this in their mind?

Maybe they resented that the family got to keep their home? Why do they get to keep living there? Something got this killer to zero in on them.

I still can't let go with Yasuko being the main target of rage/blame or fixation for some reason. MOO

Just to reiterate from what I said in the previous page: the Miyazawas did not exactly got to keep their home.
They were also due to leave at some point, soon.

But did those young kids living and/or hanging around know those details I wonder? Was it public knowledge?

If the info was public by the city or media, would those young people even read it or be interested in that stuff? I know I wasn't at that age!

I personally do not know this information, but I could also ask the exact opposite: how do these young people know that the Miyazawa would stay for good?

Not sure either, young people don't always think ahead or are aware of "grown up" dealings.

Only trying to piece together if any potential connection or catalyst for motive. If all of a sudden most in the neighborhood disappeared so to speak or is gone except one family, a young immature, unworldly person might think the family was somehow connected to the outcome(?) Just throwing ideas around!

Hypothetically, we can say there was likely a grudge or rage. Sure, they could be completely random victims or they somehow triggered this person. Trying to figure that out...

The killer could have acted impulsively and recklessly or stewed about it over a period of time where the anger built up over time into a rage. MOO

I translated some of the comments to English. Some interesting comments which are rumour, but I still read them for any clues to be open minded.

It is an independent report by FNN (Fuji News Network) and is not definitive. “There is a chance” the culprit could have been in his 30’s at the time due to recent DNA testing.
As of yet there has been no official information or release from the TMPD revising his age.
 
  • #457
Was the perp's age range refined by recent DNA testing? There's a video from the FNN channel with "new" information. It's in Japanese.

Police leaflet:

Thank you for posting this. If this is true, so many theories would have to be reconsidered.

DNA can determine biological age, rather than absolute chronological age. For example a smoker might have DNA markers that make their biological age appear older than they really are. Even so, I think a DNA test showing the killer was in his 30s would make it very unlikely he was a teenager.

If this is true, it would be an important update IMO.

Food for thought: the man at Tobu Nikko with the hand injury the same afternoon was reported to be in his 30’s. As far as I can read in any Japanese source there was never any conclusion about him, where he went after, and who he was. He simply vanished. But it has been stated they don’t believe it was him.

At the moment the single story published by FNN, which does not even name the source of the DNA claim by the way other than “an investigator”, simply says “there is a chance the culprit is in his 30’s”. Any and all language used is non-definitive and possibilities. Those of us seriously interested in the case know how well information has been mishandled by news networks over the last 25 years.

My issue with this is that there has been no official release nor revision by the TMPD and, as it stands, is just a report by a news network. If such groundbreaking information were true I would expect the TMPD to officially report it as they’d need to change the information on their website and posters as well as update their investigative team and police across the country.

Perhaps they will in the coming days and the information will be a game-changer. I would welcome some very concrete news with proof. But until then I personally will hold my breath.

It would definitely be interesting if the age demographic was different than what's been thought all along.

The killer would be semi close in age as the parents which could be another avenue to dig into.

Still could definitely be link to the base as well. If the age is older, there's still possibilities /scenarios that could be connected to base life. MOO

*ETA: even if older, still could be a student or even TA. TMPD I think thought killer led a student life IIRC.

I can't remember if the college/university student idea was looked into, I thought there was discussion about a university in the thread, but I'd have to go look when I have time to deep dive. Also could still be the son/family of someone on base but maybe doing higher education and not necessarily high school. JMO

If the culprit were actually in his 30’s it would make it infinitely easier for him to commit the murder and remain undetected if he were from a USAF base. Him being in his 30’s eliminates many of the obstacles a teenager would face in the same situation. For me personally a change in age changes nothing but that, rather than the current working theories we have here.

Saying that though, we have recently been able to place the high school students directly next to Mikio’s workplace the same year of the murder, and the years before and after, with proof that includes photos too amongst other things.

It will be interesting as things hopefully keep progressing.
