Fifty metres beneath the world’s largest metropolis - the Japanese capital, Tokyo - is an amazing underworld river system. 6.4km of tunnels, colossal water tanks, massive pillars and giant pumps are part of an immense coordinated effort to pump floodwaters out into Tokyo Bay, and protect the city’s 35 millions inhabitants from devastating floods. But with year-round heavy rains seeming increasingly frequent, Tokyo’s flood management - already the most advanced in the world - is being pushed to even greater lengths to protect the population. Mark Horstman goes underground to explore the gargantuan underground world of Tokyo’s flood defence systems.

The scale and development level of Japanese infrastructure never ceases to amaze me...
Free documentary. All of you quit complaining on video quality.
No, quality sucks
+axeman999
only you
wtf
+axeman999 cry some more, little bitch
TruthShallPrevail4 ain't free, I still have to pay for internet connection.
When the govt actually cares for their people.
The U.S. could be doing this like this... If they weren't spending in excess of 600 billion dollars a year in defense.
Truly Infamous yes ...”defence”.... a shame....
@@namishbaranwal3522 im not takling about that..
How is it “defence” when all they do is attacking every thing around the World ??
@@audimetallica I get it. You are right.
Very beautiful country and very well governance spending money for the people of Japan not spending too much in guns and other things that can hurt people. North Korea should learn from this country.
And 250% debt to gdp ratio is great..
This is just one more example of the resilience of the Japanese people.
In the Philippines, not only do we not have gigantic flood control measures, we also have very smart citizens helping the flood by throwing garbage whenever, wherever, making Manila a huge rubbish bin. :)) Where's my "proud pinoy" squad at? 😂
I hate being filipino actually
I’d like it better if i was japanese :V or british
LOLWTF673 I bet you'd hate it even more if you were in a country experiencing famine and drought. Just be grateful and make the best out of what you have.

Dear Journeymen Pictures, just to let you know that when people talk about 720p video, it actually means that the video has 720 pixels VERTICALLY.
This is what you can do when you're not spending money on defense
"defense"
Japan still has a massive defense budget lol
Yeah but this isn't as cool as 100 Aircraft Carriers
Spencer Howard it's still little compared to what th U.S. gov. spends on their military.
Well before the US even starts building shit like this they have that 20 trillion debt that keeps rising
Incredible piece of art engineering system, huge and massive. I have been in Japan and I was amazed wlby what i have see by own eyes.
I am so glad that I came across this channel, I truly enjoy watching so many of the videos. I would suggest it to friends, the only problem is that my friends are not interested in this stuff. :( too bad... keep the amazing work up. Truly enjoyable.
different folks different strokes. At least this video shown us the importance of anti-flood in mega city. It's an asset we cannot afford to exclude yet remained invisible to public.
I feel you brother. The only thing my friends would talk about are parties, bitches and gym.
isaac sanchez a few months ago all you tube was ANTIFA TEARING down STATUE......ect blm...just BULLSHIT and MASSIVE conspiracies
@@dazza123401 Lolz, that made me laugh. Well I hope you find a friend with similar interest, because I sure hope I do too.
JP, please, put year of making of these documentaries in the description. It is an important information with these older ones.
The Japanese appreciate engineering. In America engineering is an expensive annoyance, please go away.
+Alan Fox
Murica has social engineering... yeah, useless kind of engineering.
+Alan Fox get out of here shit brain your nationality dosent shape your skill or creativity america is still 1# and has been for a long time
superlativeconspable
The truth is America is an innovative country. However, when it comes to precision and quality, America is second rate. Just look at the quality of our cars and roads, terrible.
***** well i dont know about that this man clearly attacked america for no reason and i will defend it. You may say we are poorly educated but in comparison to who? i think your wrong and your quick to take the worlds side against america but really we are in the best position and you should be grateful for that.
***** i dont really understand what your trying to get at? i have traveled out of the countries more the 6 times on vacation? ive never been to a military base i believe the army is for saps. i dont believe in war, what are you trying to imply? " a rational though empirical remark"? now could that just mean you know its true but dont fancy saying it because it sounds rather elitist and harsh, well i can understand that. but he clearly said american engineering is an expensive waste i do take offence to that yet your taking his side i dont think you are a real america your probably some milk drinker always standing up for the little guy even though hes throwing the stones your pathetic and are the one Americans should be ashamed about.
a Really amazing project but overall they did amazingly well considering the amount of natural disasters against them you got to admire them well done Japan
2:19 i really thought he was gonna hit his head
hahaha same
ﾜﾛﾀｗｗｗｗ
I was just about to type that
Same
Awesome! Thumbs up!!
awesome job Japan, one question, what did you do with all the excavated earth & rock,where did put it all.
They said they used it to build bigger levee banks. You no rissen!
They dug a bigger hole and put it all in it
11:06
we need this kind of engineering knowledge to be spread out throughout the world specially to countries that flooding is concurrent
our state, Kerala , in India is also devastated by flood ..lost roads ,highways ..we want to rebuilt the whole and tis technology finds great.Would it possible to share more details about tis technology so that we can adapt.The details like wther it is applicable in hilly terrians , because half of our state is hilly region, is it cost effective compared to other technologies?We are eager to know more about tis.Kindly share some more details.
This country does not cease to amaze me
Jakarta needs to have this one.
Han Keat Lim no, ppl just need to stop dumping in the river
Han Keat Lim you guys are sinking already.
@@richardoedward7569 so many corruptions in indonesia.Before finishing this project,the money has already gone .
It's to late for Jakarta since they are now moving the capital to the island of Borneo. Hopefully they don't replicate the same catastrophe there. . . .
Needs a book published on this for college students.
In India govt. Does nothing
Places in the USA honestly need a similar system set up in their cities as well. New Orleans would benefit from this system being combined with a Netherlands-styled levee gate and flood control system.
We need this not only in tokyo we need this in the hole world not only the flad prevention systems but also the earthquake proofing end overeating solutions like in dubai and other big cities
Excellent thumbs-up left me wanting more
Water is measured in litres, megalitres or gigalitres. Gases are measured in cubic metres. Apart from this, amazing video. Compare photos of Hiroshima 20 years after the bomb with pics of Chicago in the same time period. Thought provoking!
Are you dumb, cubic meters of water will still translate perfectly to any other form of volume measurement, its not wrong.
For those not on metric, 1530 millimeters is about 5 feet, or 60 inches of rain. That's a pretty large amount...
“Pet shop” is code word for restaurant
SUPERB!!!
Excellent video.
Awesome video. Will be showing to me children. I plan to visit Japan someday.
Incredible
Fantastic.
And way too short...
Its great that their government is constantly improving on their cities. Ours is so clogged by corruption even the basics are unstable and insufficient
Perhaps Bangkok could learn from this and fund the sinking city instead of funding the approximately 5000 generals (military and police)!
Kudos Tokyo! 👍👍👍
That's some respect for nature and taxpayer's money.
well he was right, floods have been happening a lot in 2020 just this summer. let's hope we have olympics for 2021
Mirror's Edge flash back
Soa Paolo and California could use some of this rain
Malaysia also has SMART tunnel.
Japanese engineering really gets my Tokyo tower lit up
holy shit thats amazing
I have to respect Japan,I mean they have every problem anyone can have yet they are still very successful
amazing
12 minutes of wowww!
it seems by the time the UK builds the HS2 it will be the UK version of the channel tunnel seeing as they care nothing for flood defence over here
07:10 he is entering the halls of khazad dum. i bet there is a balrog somewhere.
Philippines needs this
Wich Tokyo are we talking about? To make Choice easier: Tokyo Prefecture, Tokyo District or Tokyo Metropolian Area?
They should've done something like this for New Orleans, as well as other coastal cities......
Becky Shock but the war in Iraq is more important I guess
The music is amazing ;) anyone knows if it has any title ?
darude - sandstorm
old shit is old.. move along
When this kind of thing exists yet no one knows, I'm convinced that somewhere under, there's a real life Gundam or Evangelion ready to launch!
I think London could utilise this idea very well.
Look how much can be accomplished when a political party IS NOT in the way of building things people need and NOT in the way of building/expanding infrastructure. Take note USA.
1:33 I didn't know Crocodile Dundee went to Tokyo.
@10:26 apt background score for the first time humans roll a fatty for the aliens
Mumbai desperately needs this
I LOVE JAPAN
Thinking about Houstons drainage.Wider channels,angled hydraulic pipe effect into main channel.Any ideals WE. need to figure this out.Thank You.
The city of New Orleans could learn a thing or two from this video.
Wow
Indonesia need this 😢
We need this here in thd philippines
these halls are so big you can find Gandalf with the dwarfs there.
I wish something like this is done for Assam flood which occur every year.. instead of statue
Check out London Thames flood prevention system.... It's also good like this....
***** no no.. There have built a string of water control systems located on the surface of the water itself. These structures very much control the excess water
Sa Sa still better then America lol your government lets you get flooded so insurance companies make more off you😂 and don’t you dare say dams cos you didn’t even invent them not the mention most your great minds behind science where captured nazi scientists from ww2
I'm seeing a pattern of misspelled words, so I'm wondering if certain words are just spelled differently where this documentary director/editor is from lol.
What if TITANS attack ..
They dont have barriers.
Tokyo was shaped by fire more than anything.
It's like you guys ripped your own video off youtube into a 20mb file and then re-uploaded it.
I am India but Japan my favt country
spending money on sports, weapon, cinema is worthless, spend on human and infrastructure world will be a paradise
I live in Houston , we got 1270 mm of rain in 4 days. Many parts of the city flooded , I doubt Tokyo could withstand that sort of rainfall even with all the countermeasures they have
Wonder how much time and money it would take to build something like that in the USA with all the unionized slobs that pass for construction workers.
Or how many corrupt corporate scum would leach off the project.
thank the unions for the 40hr workweek, health insurance, overtime and sick-leave.
something like that could've been done in the usa if it wasn't for trillions of dollars being pumped into our MID and unnecessary wars for imperialistic reasons.
Don't forget all the lazy,poor workmanship quality latin immigrants.
I'm lucky i live in NC we don't get earthquakes or tsunamis
Need this in louisianna
Huge underground Parthenon to prevent flood.
Sound mixing is poor. Reduce the BG at least when conversation happens
RIP to is headphone/earbud users. I have to say, the Japanese love architecture and engineering. Just to bad most of the Japanese are afraid of the opposite sex. Honestly, if the Japanese citizens would learn to populate, then they'll be fine. And, it would be great for Western cultures to learn from their love for architecture and engineering, we'll need the Japanese when we go to the moon again, mars and beyond.
not scared of sex, they're just smart enough not to get into relationship and have dumbasses kids that they have to eventually take care for. *cough cough* africa
+Tralala T Your honestly stupid pal. For one, if you paid attention to the video, it says that the both genders are freaked out to touch the other. And two, my Japanese are even saying that both genders are chickening out when it comes to relationships with the opposite gender. (FYI, they are married to beautiful Japanese girls). There are Japanese citizens who aren't afraid to be touched, but it's few and far in between. All over the world, there are young couples with families, that includes Japan as well.
Stephen Babcock well, my experience of living with a bunch of japanese college kids prove otherwise :). They are pretty kinky when it comes to sex, but they're afraid to catch feeling LITERALLY. because feeling would lead to marriage and eventually >> kids, which in the japanese culture is A LOT of pressure. So yea, thats my point, or atleast thats what my japanese friends said.
Stephen Babcock I lived in osaka by the way, lots of kids there are having sex so I don't know, maybe its just a tokyo thing ?
This is some Neon Genesis Evangelion engineering stuff
A bit like the Thames Barrier.
My question is, did this actually help during there big tsunami?
of course! levees and seawalls break the momentum of the waves. 1,000 homes lost is better than 10,000
Chicago has a similar system.
people can avoid tsunami if they enter into ball like soccer ball zorbung please watch
@
people would enter zorb ball and zorb ball outer part is covered in hard rubber so ball does nt brak when hit sharp object and when tsunami hits zorb ball full of air rises to surface people cn exit zorb ball when at surface
Am I sponsered?
While In the Philippines?
The mines of Moria, are in Japan, not middle-earth. 7:13Lol
am I the only one that is thinking about portal while watching this?
これは、フィリピンで恩恵を受ける規模の無実の洪水の人々を殺さないために、フィリピンで最初に行うことです。
mY 720P ISN'T 720P
maybe this kind of technology can survive "the great flood".,
Yet, japan still has a ton of depth to IMF so good luck 💪💪💪
Moria in Japan, who would have thought.
their godzilla is tsunamis, floods & earthquakes
Would it stop the tsunami if not waste of time
Why do humans insist upon living in areas that are so challenging?
That sounds like an interesting research project. Let us know how it turns out.
I feel like I'm playing on a console again...
if building cities causes guerilla rainstorms, what causes west and north africas in barren landscapes?
There is no easy answer to that question. You need to research the difference between regional geographic features as they relate to regional weather phenomena. Not all cities create "guerilla rain storms. Tokyo does because it is such a massive city which creates its own weather by creating a heat island effect which increases humidity and that can enhance the high precipitation that occurs in the area.
