for an adventure that will take us to the depths of the city

The museum of sewage, or Fureai Gesuido Kan

Previously, Joseph and I visited the ToTo Toilet museum in Shinjuku

to see the technology that goes into the front end

of Tokyo's sewage

Comfort, style and amazing tech features are

all part of the amazing Japanese toilet experience.

Now, it's time to see the back end of that.

and we've come here for the rear view of it.

Get ready to dive in deep

Th museum is open from 9 am to 5pm and it's free.

and amazingly clean

well, for a sewage museum.

Most of it is underground

I changed into something more comfortable

and met Joseph 3 floors down

-So this is the museum of... -sewage

Sewage?

Oh my god, yuck

You always bring me to the greatest places

I mean, this is why you're wearing this?

Of course, I knew I was coming to the

Tokyo Museum of Sewage

But don't worry, you don't have to dress up like me,

or wear a helmet and such

you can come as you are, which is a great thing

about this experience

You know last time I seem to remember

you took me to a toilet museum, right?

After you flush, you don't really think where it goes

so this is the logical next step

The next step

This is the evolution in the toilet experience

Wow, I don't know how I got involved in this.

But you're going to have alot of fun.

Trust me buddy, come on!

There's a lot to see

A lot to see, but this guy probably wants a little more privacy

On this floor, there are a lot of technical details,

like flow patterns

Pipe repair

and history

Life was real harder without sewers in Tokyo

There was even a human fesis removal, or poop boat

to transfer it out for fertilizer, for somewhere else

If you've never been to a sewage museum before,

you probably want to know about the concept

and Izumi san is here to fill us in.

You can have a lot of fun here

It's part of fun what goes on down there.

Izumi san showed us a lot of data

like high points in the flow When people use the water the most,

in the morning and evenings

After this, we were ready to enter the main sewage pipe

The door is open to visitors in museum hours

It's like being in a submarine

Open, to a whole new world

and it stinks

This is the main sewage pipe for Kodaira City

Low flowing right now

There are a few rules in here.

I think jumping the fence won't be a problem.

The main sewage pipes were warmer than the other rooms

abuot 20 degrees celcius

With the door open, a lot of wind enters from outside

The moisture inside makes your breath steam out

This bridge over the pipe is one of a kind in Japan

and maybe the whole world

It felt like being in a cave at a waterfall.

Just not the kind of water you want to go swimming in

I'm sort of shocked that a place like this even exists

It's pretty insane that

that they had an idea 20years ago to put a viewing platform

in middle of a sewer

Yeah, and we're inside a pipe which is massive

Its crazy. It's like 4.5m wide,

and this is carrying about water from 50,000 people,

and I must say,

I thought it was going to be smelly but..

I mean it's really smelly

It's not as bad as I thought it would be.

Maybe it's because it's mixed with a lot of rain water,

They say you get used to your own scent

but this is a scent of 50,000 people.

I'm not sure I can get used to this.

but one thing that is reassuring is that

they have different types of sensors to detect different gases

so that we won't pass out due to poisoning or something

The sound

It sounds like it's coming from over there and

there must be a rapid or something

I think there is a big pipe emptying into this pipe and

It's kind of like a waterfall

that's what we can hear up here, but down here,

I mean it's really calm

you can happily float on a rubber dingy.

10 kms down here

Maybe that's the next attraction they can add to this

theme park

A boat ride

This is one of the processing plant

But I do really think it's great they have a place like this.

because it allows not just kids, but people like us

have a chance to see that there is life after a flush

yeah exactly

Normally you flush and it's gone but

no, there is a subtrainion world, and places like this

just everywhere. It's incredible.

The color of the water is not flattering, is it?

It hasn't been processed at all,

it's litterly as it comes out of the toilet, as off the street

as the bathtubs..

It's all mixed so we're not seeing big pieces of toilet paper,

or anything else you might expect because

it's already kind of broken down

through the rapids back there and stuff

so this is an authentic experience

Tokyo was hit with a sudden rain storm a few years ago

a lot of rain in a brief period of time

The result was felt in a few minutes in the main sewage pipe

Water flowing very fast, and level raising beyond the norm

It was a surreal scene

that could've been dangerous with the opening in the pipe

The camera inside the pipe recorded water near capacity.

but lowered a couple of hours after the storm moved away

from the area

The museum sewage also has a classroom

where you can see it all at a microscopic level

This is raw sewage from the pipe

and what we're looking at

The sewage is teaming with life

the kind that you don't want to get to know.

It's all very disgusting

but absolutely fascinating

I simply could not look away

A sewage safari

and we had an amazing pair of binoculars.

There is a chart for the micro orgnisms.

It reminded me of monsters,

so they created a Anime version of them, of course

to make it easier to sleep at night

It was an amazing day

one that Joseph and I will never forget

Boy that was quite an experience, wasn't it?

It was! It was more exciting than I thought it would be

Seeing with all that water level and data, I loved that.

Yeah, I liked the minute details

So every time we flush now,

we have a greater appreciation for.

Absolutely. It's like there is a museum

that caters for whatever your interest is

Tokyo is crazy

and flushing the toilet for me, is never going to be the same again

Speaking of which, I got to use the restroom

I know a really good one

If you're in Tokyo,

you pass through the unforgettable museum of sewage

in Kodaira City

It stinks
