Tokyo's Futuristic Underground Flood System 

Don’t feel like this was a side project. It feels like a mega project

Future Mega Project Idea: Simon's beard

In my early 1973 when I was in college. I worked underground in the massive storm sewers under Detroit Michigan. As you descend first is electric and gas, then steam, followed by sewer and last storm sewers. Once down to that level you Rarely returned to the surface because you were so far down. We had tables and offices down there during renovations. During lunch the rats would come out to beg for food. They were friendly since people rarely went down there. A few rats would dance for food. Underground storage of storm water was massive. Chicago built a large one decades ago. My job was assisting mapping and surveying underground.

Ah yes the underground Japanese dwarven kingdoms

For April fool's, you definitely need to do a megaprojects on something like Moria or Minas Tirith.

Another great idea for a topic about flood control in my home town Chicago. The Deep Tunnel Project would be great for this channel! Begun in 1975, and at one time the nation's largest municipal water pollution control project, it involves the construction of 109 miles (174 kilometers) of tunnels 9 to 33 feet (3 to 10 meters) in diameter excavated in dolomitic limestone bedrock as much as 350 feet (107 meters) below the surface.

Former storm water, flood control and wastewater treatment professional here, and I support Simon’s cocaine habit.

I'd love to hear something about the largest land vehicles, especially the mobile excavators they use in overground coal mining, they're insane

Simon's beard has gotten so luscious, it's going to have to start it's own channel.

the ancient water cisterns under istanbul are awesome. part of them were featured in the bond movie "from russia with love" and another cistern in sultanamet - next to the blue mosque - has been turned into the most amazing restaurant.

Simon, can you speak about the SMART Tunnel of Malaysia too? It’s a tunnel with a similar purpose as this project in Japan, except it doubles as a reservoir during wet days and a road tunnel during dry days. Go check that out. It’s a project worth mentioning.

Living and Tokyo and very thankful for all of these precautions!

Great video Blaze Master!!

Tokyo has failed to appease the Gods...more sword and or mecha fights!

Wow what a great video Simon, il remember this when I go-to tokyo on vacation. 👍

WOW! Amazing display of planning and engineering excellence!

Watching just on the thumbnail alone. Well done sir.

YESSSSS I'VE BEEN WAITING FOR THIS!!

Great stuff. What about one on the evolution of tunnel boring machines? They are expensive and awesome and rapidly evolving

Can we please stop putting how we're all going to die from global warming in every single goddamn video about anything related to water, power, transportation, heating, cooling, building, communications, space flight, and everything else. WE GET IT. WE'RE ALL DOOMED. I JUST WANT TO ENJOY THE ENGINEERING PLEASE.

That won't protect Japan against rising sea levels. For that they need to raise the ground floor in the areas where the ground is below sea level. It's not really that hard to do that. Marietta Ohio did it.

Thank you

The japanese are so far ahead of us all in civil engineering lol.

I’d been hoping this would get made!

Neat. Never knew this flood prevention system existed under Tokyo. Now that Covid-19 travel restrictions are starting to ease, I might have to go check this out myself in person sometime in the future (I live not too far from downtown Tokyo).

Japan are amazing, they have also buried all their cabling in Tokyo so far underground that they wouldn't be impacted by earthquakes.

Future mega projects The Dwight D. Eisenhower National System of Interstate and Defense Highways, commonly known as the Interstate Highway System

the fact the Japan underground flood tunnels have been in many movie and TV shows is cool as hell

Does a Balrog live there?

Yes you have seen this before but "The Snowy Mountain River scheme. Would be a good topic.

Good video 👍

Im not sure which channel this would be best suited to but I think a video on GM's automotive safety testing they did using human cadavers and live hogs as crash dummies would be awesome

Next episode: Tatra. Third oldest car and truck brand from Czech Republic. They made quirky luxurious cars and heavy duty trucks.

Thoughts of making the water be redirected into a hole that goes deeper to become steam and make essentially a super large geothermal power plant that relies on flooding to produce large amounts of power that can be used as necessary?

This place is going on my post-pandemic travel list.

Louisiana needs something like this!

several cities in the US are starting to use water permeable pavement as part of the solution to this. It looks like a normal asphalt paved road but is greatly reducing the effect of localized rain contribution in flood scenarios.

Oh awesome! I mention this a bit ago. Thanks!

You should do a video on the West Desert Pumping Project that was created to manage flooding from the Great Salt Lake.

The Japanese delved too deep. You know what they awoke in the darkness of the flood tunnels... shadow and flame. Godzilla

Please do either a MegaProjects or SideProjects on US and Soviet/Russian Air Defense systems.

Simon, the lipoma/Pilar cyst on the left side of your head should probably come out before it gets bigger so you aren’t left with a huge indent/thin skin where it one was.

It's sad that a powerhouse full of great people like Japan is running out of money.

There are clouds down there. It’s a place I would love to see in person.

Excellent video, Japanese always amazing 👏 👌

Another thing to put on the list for my post covid trip to japan.

This must have been the inspiration for the 'Nowhere' area in Control.

Side project? Yo this is bigger than a LOT of the stuff you have over on Megaprojects.

Amazing

OMFG!!! something i knew about BEFOER Simon made a video...im in shock...

Mirror's Edge has a level based on that place actually. Thought I recognized it from somewhere..

With Japanese TV's penchant for shock prank stunting the public, wonder if they have ever activated a siren and played the sound of rushing water while there has been a tour group down there?

I think this was inspired by the Byzantine cistern in Constantinople! An ancient mega project video for another time, maybe? Amazing work on your channels, by the way!🙌👍👏

We need this here in Southeast Texas

Would be great if they could harness the power of the water

love it

I got to go to Japan to build the silos. It was a pain in the arse to drain and dig at the same time. Only possible at all IMO because of a really clever solution engineers come up with. Still a lot of wet work though.

This is insanely massive. This feels like a contender for a modern wonder of the world. Not completely done with the video, but they should tap this for electricity.

This is wacky but amazing. I am curious though with flooding issues in places such as italy (if I am remembering 2020 correctly...yikes) could something like this help or even be done in an area such as theres?

Best watch out for that Balrog.

I think the Tokyo Parthenon looks like the centuries old Basilica Cistern underground water filtration system in Istanbul, Turkey.

Shasta dam would be a good side project episode

New York City aqueduct system from the Croton Aqueduct (still stands today) through the modern Catskill Watershed.

Range Rover Sport Tokyo Commercial Found it!

Similar project in Taiwan for diverting flood waters, though not at the scale of Tokyo's, is the Yuanshanzi Flood Diversion Tunnel, located west of Taipei City. It is a passive water diversion system that diverts excess water when the Keelung River's water level reaches a certain height, through a tunnel bored through a mountain that sends the water straight to the sea.

This had some amazing puns. I wanted a "bu dum dum tish"

This was a level in a video game called “Mirrors Edge” back in the day. Great game

Building this structure is one thing, but maintenance also important to make it works with very efficient. Japan and their high integrity people able to make this work. So astonished to look at it. 😮

I'm surprised Seattle and Tacoma aren't the riskiest cities in the world. They are not prepared for an earthquake, tsunami, or a volcano.

I'm sure I parkoured through this in mirrors edge

I have a bone to pick with Simon. I liked the video, so I smashed the like button and now my mouse is broken.

110% chance of finding a Balrog

3:00 ohhh thats some good background music, thats some lo-fi drum* n bass like, thats good..

Being Japan just had another Earthquake I'd like to see a follow up.

How about the Thames Barrier? That's another flood barrier that protects a major world city! Thanks 😊

Mines of Moria

SMART tunnel in Kuala Lumpur, Malaysia ? That's a flood diversion project

Hi Simon

wow, just wow

Alfa class submarine and the stannard rock lighthouse in lake superior, please!!!

You would think the US Cities would copy the Japanese solution. I guess in the US we rather pay out insurance claims instead of preventing floods to begin with.

Meanwhile, here in the UK, the government can't even stump up for sandbags and a bucket, let alone build a giant underground tank like Japan did... :P

How did this cope with the tsunami that hit Japan in 2011? Or was Tokyo not hit that severely?

Goddamn Mines of Moria.

So you were fooled by the cover story, for the Gojira containment system.

This looks like the foundations of the oldest house in 'Control'

A future sideproject might be the lærdal tunnel?

Holy Beard Batman!

Wow this must be a lost kingdom of the dwarfs its huge

Can you do one about their Kaiju wall ....

Could you make another channel dedicated to humans control of water? I think it's been at least a week since you launched a new channel now.

Hi can you do a video on kansai airport

Do they charge more for a tour if you go during a typhoon?

Feed the algorithm

So THAT’S where Meruem and Netero had their ultimate battle!

Remember, much of the city of Tokyo essentially sits on the river delta of several rivers. That's why it was prone to flooding in the past and why they built that gigantic water diversion system in the first place.

As a plumber in Canada I can say we hit our 150 year rain fall and snowfall high every year lol, that being said, more plumbing videos!! Plumbing of anything lmao!

Could this have been what the fabled ancient Egyptian labyrinths were actually originally used for?
