Neighbor’s Demolition Turns Ugly: Police Called Over Missing Permits, 5ch Reports

From our other sites

The story

A thread on 5ch’s Newsoku VIP board reported a dispute over demolition work starting next door that escalated to calling the police. Officers showed up but only issued a warning, and posters quickly noted that neither the demolition company’s name nor a required permit notice was posted anywhere on site. The thread grew into a discussion of legal requirements, with users pointing out that removal of asbestos-containing materials requires advance notification, and others suggesting a report to the Labor Standards Office.

Police are here

You don't use a bulldozer for demolition

Re: #8
They're using one
Some kind of CAT (Caterpillar) machine
19AnonymousAug 22, 2026 11:00
Wait, wasn't your house supposed to be surrounded by roads on three sides, with only one side bordering a vacant lot?
I remember you writing something like that back in the sensor-light drama thread

Re: #19
Sensor light?
21AnonymousAug 22, 2026 11:01
So that's why the police came, right?
What happened?

Re: #21
They're getting a warning right now

Re: #27
Unless the other guy's yakuza-affiliated or actually breaking a law, nothing's gonna happen, right?
37AnonymousAug 22, 2026 11:07
Re: #33
Huh?
They ARE breaking the law
Demolition of asbestos-containing material requires wetting it down first
and advance notification is mandatory
34AnonymousAug 22, 2026 11:05
Whenever someone asks this guy why he'd bother hiding his ID when there's no need to, he never answers
38AnonymousAug 22, 2026 11:08
Re: #34
Is it actually required to post one?
40AnonymousAug 22, 2026 11:09
What's the name of the demolition company?
41AnonymousAug 22, 2026 11:10
Going ID-less is itself an ID (in 5ch, you can hide your poster ID)
They're all the same person
44AnonymousAug 22, 2026 11:11
I've got my own demolition neighbor drama going on right now too

Re: #44
Right?
Are they doing something illegal?
47AnonymousAug 22, 2026 11:13
Re: #43
Nope
Everyone hiding their ID here is you

Not me lol
49AnonymousAug 22, 2026 11:13
Straight to the bulldozer for demolition? lol
Are they filming a movie or something lol
55AnonymousAug 22, 2026 11:19
Re: #49
Don't they sort it by material type?
64AnonymousAug 22, 2026 11:23
Re: #55
Not sure if it's day one of demolition, but you normally don't use a bulldozer for this lol
Going straight to the bulldozer is either Showa-era yakuza business or a movie shoot lol

Re: #64
It's yellow and black? and it says CAT on it
71AnonymousAug 22, 2026 11:27
Re: #53
They're smashing through the demolition without spraying any water at all
The dust is insane, my laundry's covered in it
And of course there was zero advance notice
No demolition permit posted either, it's a company that clearly doesn't care about the neighbors and won't even give their name
Calling the police was completely pointless
72AnonymousAug 22, 2026 11:28
Re: #71
What do you mean calling the police was pointless?
74AnonymousAug 22, 2026 11:29
Re: #67
Isn't that a mini excavator? It's got an arm (the hand-like attachment on heavy equipment)
Anyway if you want to know the company name, there's a sign posted — just look at that, it's got the demolition permit info on it too
77AnonymousAug 22, 2026 11:30
Re: #74
That's exactly it!
No sign, no demolition permit
81AnonymousAug 22, 2026 11:30
Re: #72
Apparently depending on the size of the demolition site they're supposed to post a permit notice, but not doing it isn't actually a crime, so nobody will do anything about it
Since I don't even know the demolition company's name, I can't even file a complaint about the noise, dust, or vibration
84AnonymousAug 22, 2026 11:31
Re: #81
That's a city hall matter
Civil, not criminal
91AnonymousAug 22, 2026 11:35
Hang in there
By the way, I once had a guy pretend to apologize and then try to headbutt me point-blank
I barely dodged it, so be careful
100AnonymousAug 22, 2026 11:39
Police first
Then a report to the Labor Standards Office, maybe?
101AnonymousAug 22, 2026 11:39
Re: #100
You really know your stuff
That's exactly right
102AnonymousAug 22, 2026 11:40
Re: #99
Are the police actually coming? How many people are on site right now anyway? If this goes badly the crew might get hauled in lol
106AnonymousAug 22, 2026 11:41
Re: #102
They're already here
116AnonymousAug 22, 2026 11:48
For a single-house demolition, they often don't bother putting up a sign, right?
118AnonymousAug 22, 2026 11:48
Re: #116
It's two buildings
And not posting one is a violation of the ordinance
123AnonymousAug 22, 2026 11:50
Re: #116
Normally it has to be posted somewhere visible to ordinary passersby too — maybe it's just hidden because the site's so cramped?
Though in this case it sounds like there's just nothing there lol

Background and Key Points

Neighborhood demolition in Japan runs on a layered set of rules that this thread only partly gets right. Under the Construction Recycling Act, contractors demolishing buildings above a certain size must post a notice board at the site listing the company name, the registered demolition permit number, and the site supervisor — a requirement several posters correctly cited, and the site’s silence on both company name and permit is what triggered the “call the police” escalation. Separately, the Air Pollution Control Act and related asbestos ordinances require pre-work surveys and advance notification to authorities before disturbing asbestos-containing material, plus dust suppression (commonly wetting debris down) during removal — the “no water spraying” complaint posters raised. Police involvement here is a red herring: officers can only respond to an active crime (trespassing, assault, obstruction), not to a paperwork violation, which is why they issued a warning and left.

Where the thread actually splits is on consequence: some posters treat the missing notice board as proof of an outright illegal operation worth fearing, while others (correctly) point out that failing to post the sign is a municipal/administrative violation, not a criminal one — meaning the appropriate next step is a complaint to city hall or the Labor Standards Office, not the police.

What the thread never spells out for outside readers is jurisdictional: enforcement of these demolition and asbestos rules doesn’t sit with the police at all but with municipal building-safety divisions and labor bureaus, agencies most residents rarely interact with. That gap explains both the poster’s frustration (“calling the police was pointless”) and why identifying the contractor — normally trivial via the legally required signage — becomes the actual bottleneck once that signage is simply absent.
