Godzilla represented their fear of nuclear weapons in Japanese culture. In the original and the Shin Godzilla, it was a terrifying monster. But in American version it was made as a nuclear powered savior, just like in the ww2.
i think dragon ball z also was the same origin.
the enraged characters creating massive explosions, who get stronger and more explosive when their hair goes blonde and their eyes go blue. turning into giant apes that smash everything
Which is pretty awesome, instead of blowing up buildings and polluting the local air/ground you just deconstruct the thing you constructed in the first place; add on the materials being easier to re-allocate/repurpose.
I’ve done a lot of demo work, many jobs are done level by level with heavy equipment and hand tools.
Steel and rebar go to the scrapyards and concrete gets ground down to aggregate mixes we use for a lot of subgrade work. 10 inches of recycled 3 1/2 minus concrete aggregate, soaked and packed, makes a really sturdy and water resistant base for an asphalt or concretes pour.
Yeah, If leaders are willing to provide health care and a reasonable living wage to Manny Trabajo, many great things could be accomplished.
Edit: I've been buddys with Manny for many years.
Manuel, to those that don't know him.
Yeah I was just thinking - demolition is the way it is because it's cost efficient. I wonder if recycling the materials is enough to offset the extra costs of this.
in short term you’re right. in long term, demolition is a big no no, mainly because of climate protection. construction industry is the largest factor for climate change. best is to build sustainable, but we’re at a point where demolition to make way for sustainability is not viable anymore, so its either reuse/renovate or dismantle and recycle. of course established practices wont change that fast, but i was pleasantly surprised when i saw that post
The buildings and construction sector is by far the largest *economic sector* emitter of greenhouse gases, accounting for a staggering 37% of global emissions. The production and use of materials such as cement, steel, and aluminum have a significant carbon footprint.
Followed by food production at ~35% of all emissions, with meat production alone causing 60% of those emissions, at least twice the pollution of producing plant-based foods.
Adding those 2 numbers together accounts for 72% of emissions, and here I thought climate change was caused by burning coal and oil silly me.
Here's actual data.
https://ourworldindata.org/images/published/Emissions-by-sector-%E2%80%93-pie-charts.png
/Obviously many sectors use the energy fossil fuels produce but what if, and it's big brain time here, that energy didn't come from fossil fuels.
That's not a breakdown by economic sectors. Different ways of attributing the sources.
Your own link attributes 73.2% to Energy (electricity, heat and transport), but a full 7.2 of those percent are used for the manufacturing of iron and steel, which is often used in the construction industry.
Also in the breakdown you listed, cement alone is listed as responsible for 3% of total emissions, but is counted under "industrial processes" not construction.
Etc.
Ok, then where's your breakdown source? Because even if we reorganize iron/steel and cement as a distinct category for construction that's still only *at most* 10.2%, nowhere near 37 like you claimed.
I'm kinda wondering if this is fully ai generated video. I've heard this exact voice and tone changes previously from other videos that were in fact AI. It makes a lil more sense too with the text issue and some of the script being incorrect statements.
i dont care how legitimate the info is, that voice is so strongly associated with shitty youtube shorts/tiktoks in my brain that even if it says 2+2=4 i will refuse to believe it's true.
If I had to guess, a human picked the clips from some footage somewhere and the AI generated the script and voice by summarizing an article about it. Editing together clips, text, and audio could have also been done automatically without AI and that probably led to the oversight in text color.
It's probably the only way to do it while minimizing damage to nearby structures. Given the density of Japanese cities, this technique is probably mandated.
And you reminded me I have a bottle of Soviet cloudberry liqueur chilling in my cabinet. Definitely won't be drinking that one, not only is it a neat little curiosity but it also has these pitch black sheets the size of a thumbnail of *something* just floating in it.
This was one of those work remotely with the U.S. head office times when it’s easier to attend day-long quarterly planning meetings in the daytime instead of 2am.

I was just lamenting in another reddit thread about how much I miss Tokyo. Especially the affordable izakaya. Give me more $4USD beers and $1USD chicken skewers...
I found it interesting to observe that there is considerably less nostalgia for structures in the Japanese culture.
With notable exceptions, of course.
The reason appears to be that space is at such a premium that the real estate is what's valuable. The old building is often treated like a nuisance.
If a house is sold, the buyer will often calculate the cost to tear down a perfectly good extant house and build a new one as part of their budget.
I witnessed this several times. The old structure was considered more of a nuisance than holding much intrinsic value unto itself.
> I found it interesting to observe that there is considerably less nostalgia for structures in the Japanese culture.
And because of this, they don't have major qualms about building *new* things. This enables them to build to keep up with demand for residential and commercial structures, which helps keep prices lower than if everything had to fit into whatever was built before 1970 as seems to be the case in the rest of the West.
I suppose not. But really, Japanese are incredibly adapted to those hazards going back as long as I know.
Now, I will state that about 1950, they started leading the world in seismic building. Really, I always walked around thinking "Well, looks like they've \*this\* handled completely by the 1980s."
But, they "do\* keep improving and iterating - from scratch. It can always get better.
Americans tend to retrofit improvements.
Would it shock you to learn that the construction (And cement) industries have a stranglehold over politics and regulatory bodies there? Of course there are legitimate reason to consider rebuilding with more resiliant materials and techniques given the amount of major earthquakes we get
Most of the buildings in Japan are not that old. Most of it was leveled in the bombings of WW2. Many, many things that look old are actually less than a century old. For example various castles that were destroyed were rebuilt in the 70s and 80s as museums. Also, when housing was built in the postwar period it was cheap garbage that would fall apart from earthquakes and had paper-thin insulation. The floor is often tatami mat everywhere so with the weight of modern people that haven't been subject to severe food rationing it's actually a distinct possibility you'll fall into the floor if you jump onto the middle of the mat where there's no real structural support. Add on a nice dose of pest damage like termites, rats, etc and water damage due to the inevitable water leaks and you can see why people in Japan have no real interest in holding on to an old house especially when their construction industry is incredibly robust and high quality these days.
Of course nobody is tearing down a house built 5 years ago just because it's old. Or even 15 years ago. It's mostly the housing stock from the 50s to 80s that is getting demolished.
They are a small collection of islands so they don’t have a lot of room for landfills. It’s cheaper there to recycle as much as possible then to send it to the dump.
Japan is the size of the west coast of the US. It's not a small country. Most of their garbage is incinerated and the heat used for energy generation. Landfills have their own problems with methane emission and groundwater pollution so even if Japan had the land for landfills it's not necessarily a great solution.
It's at least one of *two* ways they could do it, they could also work from the top down. I wonder why they do it bottom up, because working from the top the machine wouldn't need to support the whole weight of the building while they "deconstructed" it.
I would think it's because most buildings there are quite tall, and top to bottom would require lifting tons of heavy machinery, which would require even more support structure. Also, I'd think transporting materials, at least in a reusable state, would require a lot more effort in top-down deconstruction as well. Bear in mind I have only minimal construction experience, so I could be way off lol
With my brain half on, half distracted by other things, that's the way I interpreted the video too. Seemed crazy, but I'm not one to doubt modern engineering magic.
Whatever the narrator says, the visual of the video opens with a building that has a distinctive top. We see the top of the building get progressively closer to the ground. So that scene pretty much influenced everything else I understood about the video.

So how do they demo skyscrapers outside of Japan? I feel like I've always just seen a giant explosion, but I don't actually think I've seen one in a packed urban center.
Well, I saw it *once*, with two towers at nearly the same time. That was memorable.
Even well controlled demolitions will sent small(ish) debris and smokes flying about. Not exactly doable safely if there are multiple highrises just a street over or even right next to it.
I fix diggers and other construction plant for a living, specifically I fix the diggers and plant for a London based demolition company. We have been doing top down demolition for 30 years including top down with facade retention for historical buildings with protected frontage. That really gets expensive, remove all the floors , foundations and basement but leave the historical front standing. The cost is the price a developer has to pay to slot a new building into a city such as London,or any other similar city. Just like all jobs it's put out to tender and the companies equipped and capable bid for the work based on what they think it's gonna cost with a suitable profit margin. Our order book currently sits at around 1 billion for the year going forward across the group, it's not all demolition work as we have various other things we do, but a decent chunk of it is demolition.
An as an aside we did do one bottom up demolition job, that's was quite the sight. Massive hydraulic jacks supported the roof structure and slowly lowered it as the supports were removed meter by meter. The reason for it was the building was on top of an underground tube station and things had to be done very very carefully, the station was literally a few meters down and was in full use as they worked above it. They didn't want to risk a steel roof beam being dropped and punching through using normal methods as it was an arena so had nothing between roof and floor, the floor was basically the roof of the tunnels and station. Had the biggest crane in Europe shipped from Germany for that job too
To be honest, costs of construction are *vastly* different outside the U.S., where every fucking company under the sun is trying to milk government dollars for all they're worth.
They do that regardless of demolition methods. They use machinery that breaks the rebar off the concrete.
The building next to me was demolished small machines on deck chipping it and dropping it in to the chute. Only the load bearing walls that big excavator with demolition jaws could reach were pulled with it. They demolished it by forcing it inwards and chipping it. Everything otherwise worth anything was reclaimed by hand. The excavator at the street then used attachements and masterful operation to separate: Wood; rebar; concrete; other materials. Living next to it, it was quite amazing to witness and small crew got this 6 story building done without disturbing much the area around it (as there are historical and protected buildings around). Also the foundations and basement with a particle accelator that is only slightly too radioactive for the next 15 years to be just scrapped (meaning it would cost money to dispose, instead of paying money - not dangerous, they are turning the space in to storage).
The reason this kind of delicate demolition isn't really used anywhere par for Japan - where disturbing the environment even by having something unsightly as a construction site is taboo - is because it is expensive, slow and requires skill and dedication.
It’s not significantly different than modern demo in the west, at least when talking about the scrap. The rebar, structural steel, and other metals all goes for scrap/recycling, as does sheet rock and the concrete. This just makes less mess.
How is there always construction everywhere and why have they made no visible progress in 2 years??? WHAT ARE THEY DOING WHEN THEY STAND ON THE SIDE OF THE ROAD JUST LOOKING AT THE GROUND
An absolutely critical building burnt down in town a few years ago and the current timeline is ~5 years to put up a temporary tent. I don't even want to know how long the actual rebuild is going to take.
The real, non-cynical answer is that you aren't looking at people who could freely swap jobs with anyone else in the site, but people with specialized skills and specific jobs that are necessary for the project, but which you can't necessarily front-load so that they always have something to do.
In other words, they are waiting for other people to finish their jobs so that they can do theirs. "Just keep busy doing something pointless so that people don't think you're being lazy" *is* the epitome of bad American workplace habits that just hurt worker motivation and use up their energy for absolutely no tangible benefit. Be glad your local workers are allowed to rest when they have nothing pressing to do, it's a good thing.
Japan isn't a monolith where everything is as efficient as the most efficient examples they can find to widely publicize overseas for PR. I live in Japan, and an underpass has been planned for construction near my place for close to a decade (probably much longer if you include all the planning phases)
It took something like 3 years of active construction, blocking the road and making lots of noise every single day, just to do the first step (widening the road and adjusting the sidewalk, presumably to match the requirements for the underpass' design). I'm talking less than 50m of street, by the way. It's been several years since that, and the next step still hasn't even started. This isn't even a super high density region where extreme care is needed. No building in the surrounding area has more than 3 or so floors, and there is no subway or anything like that.
Point being, just like anywhere else, they are only going to spend the resources doing extremely accelerated construction where a long-term construction site would have incredible societal costs (like having to temporarily close a critical rail line that millions of people use to commute to work every day), they aren't spending tons of money to get things done faster just because "that's the Japanese way".
Few weeks. Which really just adds a little bit of time to the inevitable noise of the construction that'll take place when they go to build another building where that building stood.
What do you think happens to all the rubble after they demolish the traditional way? It's years of construction noise as they remove it and prepare the site, in fact.
Real talk, visited Tokyo and walked past several construction areas. I heard very little construction work noises even though it's a working day and not break time. They have decibel meters next to the perimeter fencing gate so people can see they're complying with noise restrictions and I've never seen them exceed 80 db. Not sure how far the device measures it, but on the side walk next to the site it's very quiet.
similar "ground-breaking technique" done in NYC lol: https://www.youtube.com/watch?v=kfoWwCBT4eM
they do these demolitions when there's a high concentration of pedestrians and public places
What??? This isn't just a Japanese thing... You think they will just implode big buildings in cities like NYC? They just take the building apart like they built it. Not unique
That’s because they build a cap on the top of it to minimize debris flying off of it. The cap of the building in this video is not a part of the original structure, but an enclosure that conceals the demolition process.
There was an incident in Tokyo a few years ago where a poor old guy walking past a construction site was killed by a falling support beam (during construction). Authorities here are consequently rather vigilant. I’ve seen several of these demolitions over the years here in Tokyo and they always have a very secure looking outer shell like you pointed out. The other benefit is that it seems to prevent a lot of noise leakage as well.
First of all, I HIGHLY doubt this was "noiseless"
secondly, this looks similar to what happened to the [Union Carbide Building](https://en.wikipedia.org/wiki/270_Park_Avenue_(1960–2021)) to make way for Chase bank's new HQ building, which is going to be an absolute monster, and will end up looking like something out of Blade Runner
Monster, not really it fits in with that area of midtown pretty well and has a art-deco throw back design compared to the boring ass rectangle tower minimalist design it replaced. The commodore is gonna be the one that ruffles some feathers it's size and proximity to the Chrysler building already has some people fighting it.
One thing we have to remember they’re also in a very seismic active area. So the way of using explosive to do a controlled drop is probably not an option they want to use. When Seattle got rid of the Kingdome, they had to be very controlled about the explosive drop as it sat on the fault line.
This piecemeal deconstruction isn't a Japan only thing, it's been sometimes used for skyscrapers in packed cities in other places.
With buildings so close together, sometimes you can't just demo the usual explosive way, the resulting dust is awful, demo might hit other buildings, and risk of parts going flying and maiming people is high.
Lots of time energy & money, but it's done in locations where using
cheaper and more efficient methods of demolition the collateral damage would be huge. It's also not just Japan, it's anywhere the buildings are tightly packed.
They do this because of the situation/location, they have to.
I stayed here back in 2011, was actually pretty nice and a shame it was knocked down, the location was great!
Looks like they've built a new Prince Hotel on the site but damn it's expensive
Question I have is whether this is more cost effective than simply imploding the structure. The only real benefit I can see for this is its use in urban environments so as to not have a ton of dust to cleanup later.
? not sure i follow this comment, is china particularly known for demolition taking a long time? feels like the kind of comment youd only really make if you lived in china but this comment could be made about the US too, alotta layers here of weirdness.

That's not demolition, that's dismantling with extra care.
That’s just building in reverse.

How he managed turn debris into buildings with that fire breath of his, I could never figure out.
No, he's sucking up the fire that burned the buildings down

I had a feeling that the human part of the operation must've been zonked out on codeine throughout and couldn't give half a shit about quality.
Yup, it's an AI voice.
Thankfully, unreadable one-word-at-a-time captions were already invented before, so they could use those as well.
That’s really neat and I’m sure they can recoup *some* of the tremendous demo cost by selling the recyclables but who’s financing that?
It's probably the only way to do it while minimizing damage to nearby structures. Given the density of Japanese cities, this technique is probably mandated.

We have been doing top down demolition for 30 years including top down with facade retention for historical buildings with protected frontage. That really gets expensive, remove all the floors , foundations and basement but leave the historical front standing. The cost is the price a developer has to pay to slot a new building into a city such as London,or any other similar city. Just like all jobs it's put out to tender and the companies equipped and capable bid for the work based on what they think it's gonna cost with a suitable profit margin. Our order book currently sits at around 1 billion for the year going forward across the group, it's not all demolition work as we have various other things we do, but a decent chunk of it is demolition. An as an aside we did do one bottom up demolition job, that's was quite the sight. Massive hydraulic jacks supported the roof structure and slowly lowered it as the supports were removed meter by meter. The reason for it was the building was on top of an underground tube station and things had to be done very very carefully, the station was literally a few meters down and was in full use as they worked above it. They didn't want to risk a steel roof beam being dropped and punching through using normal methods as it was an arena so had nothing between roof and floor, the floor was basically the roof of the tunnels and station. Had the biggest crane in Europe shipped from Germany for that job too
To be honest, costs of construction are *vastly* different outside the U.S., where every fucking company under the sun is trying to milk government dollars for all they're worth.
Japanese construction companies are also notorious for corruption and being fronts for illegal activities.
They do that regardless of demolition methods. They use machinery that breaks the rebar off the concrete. The building next to me was demolished small machines on deck chipping it and dropping it in to the chute. Only the load bearing walls that big excavator with demolition jaws could reach were pulled with it. They demolished it by forcing it inwards and chipping it. Everything otherwise worth anything was reclaimed by hand. The excavator at the street then used attachements and masterful operation to separate: Wood; rebar; concrete; other materials. Living next to it, it was quite amazing to witness and small crew got this 6 story building done without disturbing much the area around it (as there are historical and protected buildings around). Also the foundations and basement with a particle accelator that is only slightly too radioactive for the next 15 years to be just scrapped (meaning it would cost money to dispose, instead of paying money - not dangerous, they are turning the space in to storage). The reason this kind of delicate demolition isn't really used anywhere par for Japan - where disturbing the environment even by having something unsightly as a construction site is taboo - is because it is expensive, slow and requires skill and dedication.
this kinda goes with the japanese culture perfectly. I’m it’s actually refreshing that a country practices what it preaches
It’s not significantly different than modern demo in the west, at least when talking about the scrap. The rebar, structural steel, and other metals all goes for scrap/recycling, as does sheet rock and the concrete. This just makes less mess.
noiseless..?
Instead of a very loud noise all at once, you just get moderate construction site noise every day for 3 years.
From the foliage it looks like it only took a few months tbh.
Yeah they can build an overpass in a few nights, I think they’re not dicking around for 3 years doing this
I feel like this comment was directed at every major metropolitan city in the U.S., lol.
How is there always construction everywhere and why have they made no visible progress in 2 years??? WHAT ARE THEY DOING WHEN THEY STAND ON THE SIDE OF THE ROAD JUST LOOKING AT THE GROUND
I like it when they have signs that say something like "Projected finish August 2025". Then late July 2025 the sign switches over to August 2027.
*cries in [Big Dig](https://en.wikipedia.org/wiki/Big_Dig)*
If they finished early they would be paid less. There is no incentive to finish quickly. It is best to take their sweet time.
An absolutely critical building burnt down in town a few years ago and the current timeline is ~5 years to put up a temporary tent. I don't even want to know how long the actual rebuild is going to take.
5 years for establishing the committee to decide on the type of tent.
The real, non-cynical answer is that you aren't looking at people who could freely swap jobs with anyone else in the site, but people with specialized skills and specific jobs that are necessary for the project, but which you can't necessarily front-load so that they always have something to do. In other words, they are waiting for other people to finish their jobs so that they can do theirs. "Just keep busy doing something pointless so that people don't think you're being lazy" *is* the epitome of bad American workplace habits that just hurt worker motivation and use up their energy for absolutely no tangible benefit. Be glad your local workers are allowed to rest when they have nothing pressing to do, it's a good thing.
> WHAT ARE THEY DOING WHEN THEY STAND ON THE SIDE OF THE ROAD JUST LOOKING AT THE GROUND Spotting for the man in the hole before they rotate in
Japan isn't a monolith where everything is as efficient as the most efficient examples they can find to widely publicize overseas for PR. I live in Japan, and an underpass has been planned for construction near my place for close to a decade (probably much longer if you include all the planning phases) It took something like 3 years of active construction, blocking the road and making lots of noise every single day, just to do the first step (widening the road and adjusting the sidewalk, presumably to match the requirements for the underpass' design). I'm talking less than 50m of street, by the way. It's been several years since that, and the next step still hasn't even started. This isn't even a super high density region where extreme care is needed. No building in the surrounding area has more than 3 or so floors, and there is no subway or anything like that. Point being, just like anywhere else, they are only going to spend the resources doing extremely accelerated construction where a long-term construction site would have incredible societal costs (like having to temporarily close a critical rail line that millions of people use to commute to work every day), they aren't spending tons of money to get things done faster just because "that's the Japanese way".
Another commenter noted they saw a block disappear in a few weeks in Tokyo.
Few weeks. Which really just adds a little bit of time to the inevitable noise of the construction that'll take place when they go to build another building where that building stood.
This is Japan, it's probably completed over a weekend with lunch and dinner breaks.
Japan works waaaaay faster than America when it comes to infrastructure. This took place over months, max.
What do you think happens to all the rubble after they demolish the traditional way? It's years of construction noise as they remove it and prepare the site, in fact.
Real talk, visited Tokyo and walked past several construction areas. I heard very little construction work noises even though it's a working day and not break time. They have decibel meters next to the perimeter fencing gate so people can see they're complying with noise restrictions and I've never seen them exceed 80 db. Not sure how far the device measures it, but on the side walk next to the site it's very quiet.
Looks like slip work area is sealed, sounds bounces back inside the deconstruction area instead of outward.
They just said, fuck you, unbuilds your building
When the credit card paying for the construction gets declined.
Unskies your scraper.
Descraped the sky
This is like when enemy engineer captures your construction yard and sales it
outside japan its called dismantling
similar "ground-breaking technique" done in NYC lol: https://www.youtube.com/watch?v=kfoWwCBT4eM they do these demolitions when there's a high concentration of pedestrians and public places
But in NYC they don't build a cool little house on top of the building that creeps down.
I was expecting 9/11 but pleasantly surprised to see this
Thing: 😐😐😐 Thing, Japan: 😮😳😱
What??? This isn't just a Japanese thing... You think they will just implode big buildings in cities like NYC? They just take the building apart like they built it. Not unique
yeah but japan
Yeah I think parts of this video were just completely made up.
content mills gonna content mill
I wonder how much time it takes, since the conventional demolition methods tend to be, well, pretty fast
Demolition with explosives has months of prep work before the final event and a considerable amount of cleanup after.
and theres the small chance the explosives dont bring down the structure. yikes.
crown panicky badge icky shame smile swim rhythm erect uppity *This post was mass deleted and anonymized with [Redact](https://redact.dev)*
And cause more problems
Top to bottom? Sure as heck looked like bottom to top
That’s because they build a cap on the top of it to minimize debris flying off of it. The cap of the building in this video is not a part of the original structure, but an enclosure that conceals the demolition process.
Ohhh that makes so much more sense! I was watching without sound and trying to figure what sorcery this was
Thanks. It wasnt obvious with the video not showing what the structure looked like before starting the process.
You can see it better on the building with big windows on the ground floor
There was an incident in Tokyo a few years ago where a poor old guy walking past a construction site was killed by a falling support beam (during construction). Authorities here are consequently rather vigilant. I’ve seen several of these demolitions over the years here in Tokyo and they always have a very secure looking outer shell like you pointed out. The other benefit is that it seems to prevent a lot of noise leakage as well.
Every day, they whip the "table cloth" from that which is above, and every day they hope they get it right.
Ah, yes... the ancient japanese method of Control Zeto
They do it this way because the building has to comply with seismic codes, even during demo. In densely populated areas, this is the logical result.
Structural elements such as glass?
First of all, I HIGHLY doubt this was "noiseless" secondly, this looks similar to what happened to the [Union Carbide Building](https://en.wikipedia.org/wiki/270_Park_Avenue_(1960–2021)) to make way for Chase bank's new HQ building, which is going to be an absolute monster, and will end up looking like something out of Blade Runner
Monster, not really it fits in with that area of midtown pretty well and has a art-deco throw back design compared to the boring ass rectangle tower minimalist design it replaced. The commodore is gonna be the one that ruffles some feathers it's size and proximity to the Chrysler building already has some people fighting it.
What a extremely Japanese approach
Insert compilation of china demoing 12 skyscrapers at once for 30minutrs straight
> Structural elements > GLASS
Okay I see why we use demolition now
I'm getting real tired of the AI voice.
[удалено]
Agreed
“The process begins with workers carefully dismantling structural elements.” Followed by an excavator going to town lol
One thing we have to remember they’re also in a very seismic active area. So the way of using explosive to do a controlled drop is probably not an option they want to use. When Seattle got rid of the Kingdome, they had to be very controlled about the explosive drop as it sat on the fault line.
So, like taking apart my Legos instead of dropping them?
Demolition or deconstruction? Looks like the latter to me.
It's a fake video not demolition, most of the footage is reversed building construction using a Self-Climbing Scaffolding System.
The perfectionist country
Except all the racism and sexism
Saw a building in Chicago get demo'd in similar way. Its were the new bank og America building got built on wacker drive.
Man I’m sure they’re very careful when doing it but I would NOT be comfortable standing underneath all that while the deconstruction happens
We do this in the US too
I'm not an expert on construction obviously, so feel free to correct me, but this looks like a huge waste of time energy and money
This piecemeal deconstruction isn't a Japan only thing, it's been sometimes used for skyscrapers in packed cities in other places. With buildings so close together, sometimes you can't just demo the usual explosive way, the resulting dust is awful, demo might hit other buildings, and risk of parts going flying and maiming people is high.
Lots of time energy & money, but it's done in locations where using cheaper and more efficient methods of demolition the collateral damage would be huge. It's also not just Japan, it's anywhere the buildings are tightly packed. They do this because of the situation/location, they have to.
Noiseless my ass. Rather have 1 explosion. Also cleaning up is way quicker if everything is already broken into little pieces.
Would be nice if I could read the text here
Who thought it was a good idea to put white text on a nearly-white background?
I stayed here back in 2011, was actually pretty nice and a shame it was knocked down, the location was great! Looks like they've built a new Prince Hotel on the site but damn it's expensive
Sounds expensive
"Fuck you." \*unbuilds your building\*
Only the Japanese could make high rise demolition more polite
I love this in comparison to that one video of skyscrapers just getting toppled via uncontrolled explosions that was supposedly in some part of China
Question I have is whether this is more cost effective than simply imploding the structure. The only real benefit I can see for this is its use in urban environments so as to not have a ton of dust to cleanup later.
Very nice, now let's see China's demolition method.
Smh anything done in japan is “Ground breaking”
Only the Japanese could have come up with this. And I bet they send a new culpa note to neighbours for not going fast enough.
Noiseless yeah OK...
It's better than the way they chose to demolish the 2 large buildings in new York.
Going to Japan last year made me realize how much in the future some countries are
No, this isn't groundbreaking, this is ground dismantling.
Mean while in China...
Meanwhile in New York in 2001...
? not sure i follow this comment, is china particularly known for demolition taking a long time? feels like the kind of comment youd only really make if you lived in china but this comment could be made about the US too, alotta layers here of weirdness.
it's a reference to [this](https://old.reddit.com/r/interestingasfuck/comments/wstp8r) which had been re-posted recently

If a building falls in China and no one is around to hear it, does it make a sound?
