Tokyo's Underground Discharge Channel

Re: Tokyo's Underground Discharge Channel
#12It's amazing just how much stuff there is under Tokyo - not just infrastructure like this and the usual transport links but entire multi-storey shopping malls. There's almost a whole city beneath the city. It's possible to travel for miles without ever seeing daylight!
My favorite part is the JSDF underground bunkers where they store the giant robots used for disaster relief.

Osaka has also massive undergrounds. Not as large as Tokyo's of course, but massive nonetheless.

#14Tokyo was a city of canals before the Allies firebombed the city. Apparently the canals boiled due to the incendiaries used, so there was no escape from the fire during that tragic phase of life in the city. 100,000 deaths in one night is a statistic that few people think about, the Nazi death camps worked at a glacial pace in comparison, the craziness of WW1 campaigns gains a new perspective too, the bombing of Toky…
Dresden was also completely destroyed by Allies (for no good reason) and its firebombing caused between 200 000 and 300 000 victims (largely women, children and elderly). We don't talk about it much even though it was a crime against humanity as well.

#15These enormous underground projects are so interesting.
I've been following the Chicago Deep Tunnel project, which is nearing completion after half a century of work.[1] Because Chicago was built on swampland and next to the lake, rainwater used to be a huge problem because it didn't have anywhere to go when it rains, except into sewers - which used to be well under capacity for burst rainfall, which led to basement flooding etc.
So the city is building (and almost finished with) a set of huge tunnels across the entire city that regular sewers will drain into during flash floods, and then pump the water out to reservoirs repurposed from abandoned quarries on the edge of town. The target capacity is 17 billion gallons, which is apparently the volume of twelve football stadiums stacked together? [2]
I'd love to tour that construction. Not sure they offer public tours though. :)

Where is this and how do I see it ?

Milwaukee, WI is building a Deep Tunnel project as well. It's certainly not as large as Chicago's, but the need is similar (city built on swampland). They are, after all, neighboring cities on Lake Michigan.

From the Wikipedia article supplied:
“Large variations in the claimed death toll have fuelled the controversy. In March 1945, the German government ordered its press to publish a falsified casualty figure of 200,000 for the Dresden raids, and death toll estimates as high as 500,000 have been given.[15][16][17] The city authorities at the time estimated up to 25,000 victims, a figure that subsequent investigations supported, including a 2010 study commissioned by the city council.[18]”
It’s a tragedy none the less but that figure doesn’t seem actuate ?

#19As of last year, they now offer hourly guided tours 7 days a week for about USD$10. (In fact, I was just there earlier today!) Note: it's about 1.5 hrs (each way) from Tokyo, and you need someone in your group who can speak Japanese. Reservations here: https://reserva.be/guidetour
Here are some pics from when I took this tour last year:
