Our guest today is Watanave Hidenori,

00:11

a professor at the University of Tokyo.

00:15

He's an information design specialist

00:18

who's created the "Satellite Images Map of Ukraine."

00:24

Since the Russian invasion of Ukraine began in February 2022,

00:29

he's been mapping out the war damage for all the world to see.

00:36

He takes the images you won't see on the news

00:39

and reproduces them in 3D on a digital map, which is updated daily.

00:47

Watanave is exploring how we can use digital tools

00:51

to keep the memories of disaster and war from fading.

00:55

He hopes his work will help bring about peace.

01:00

Our memory of a disaster fades over time.

01:03

This is true for war as well as natural disasters.

01:07

Each time a new one occurs, it overwrites our memories.

01:12

In order to prevent this from happening,

01:15

each generation revives memories of past wars and disasters

01:20

using whatever method of expression will resonate with their contemporaries.

01:26

Society continues to repeat this process.

01:31

Watanave compiles open-source satellite images

01:35

and 3D images captured by people on the ground

01:38

in order to show the world the reality of what's going on in Ukraine.

01:45

Here's a satellite image of the Zaporizhzhia Nuclear Power Plant,

01:50

which is currently under Russian control.

01:54

Watanave says this view of the location reveals many things.

02:01

You can see damage caused by shelling on this roof,

02:05

which is about 140 meters from the nuclear reactor.

02:10

If Ukraine were to launch an attack and ended up causing a meltdown,

02:15

a wide area around the plant would be contaminated.

02:20

This is about 400 kilometers from Kyiv. It's not that far away.

02:27

Russia claims that Ukraine has been attacking the Zaporizhzhia Nuclear Power Plant.

02:32

But there's no reason Ukraine would launch shells so close to this area

02:36

or do something that might cause a fire.

02:41

When you zoom into the image,

02:42

we can see there are Russian army vehicles hidden,

02:47

stationed under this bridge.

02:52

The fact that these vehicles are positioned in such an orderly fashion

02:55

implies the plant is under their complete control.

03:00

If they were preparing to be attacked, they wouldn't be hiding them.

03:04

You'd expect them to be scattered around the entire area.

03:08

This suggests we should be skeptical of what the Russian side is claiming.

03:15

This satellite image itself is not direct evidence,

03:18

but it is very useful for helping us verify what is actually going on.

03:23

Watanave has also created 3D images out of photos and footage

03:28

captured by people on the ground using cameras and drones.

03:33

It makes it possible to show the reality of a situation

03:37

in a way that a satellite cannot.

03:41

This is from the town of Bucha, which people now know because of the Bucha Massacre.

03:46

A local artist painted sunflowers for peace

03:50

on these cars destroyed by Russian troops.

03:53

Sunflowers are the national flower of Ukraine.

03:59

These are images of an elementary school in Chernihiv,

04:03

a town that was under Russian control.

04:07

Dozens of children, and even infants,

04:09

were confined inside of this school for a long time.

04:17

If you look at this hallway,

04:19

you can see that the people were keeping track of the days after the Russians took control.

04:25

The children were forced to live in this space for a long time

04:29

with the fear of not knowing when they would be set free.

04:34

In the end, the bodies of many children were discovered here.

04:41

I have a daughter who's in kindergarten.

04:44

I thought about how I would feel if this happened to her school,

04:48

and I was at a total loss for words.

04:54

This all took place in the basement of the school,

04:57

so it doesn't show up in satellite images.

05:00

Ukrainian civilians are rigorously documenting all of this

05:04

because they want people to know that this place that is near and dear to them

05:09

has been affected by war.

05:14

They are putting their own lives on the line,

05:16

as they're at risk of being attacked by Russian soldiers.

05:20

And yet they're desperately documenting what's going on.

05:24

It's because of their contributions that we can make an archive of images like this.

05:31

Watanave searches the internet almost every day

05:34

for images and footage that citizens have uploaded.

05:38

After identifying the location, he publishes the images on a digital map.

05:46

Whether it's a satellite image or 3D data,

05:49

very rarely does it come with info that tells you the exact location

05:53

and what direction the camera is facing.

05:55

So all you'll know is that it was taken in Mariupol, for example.

06:00

So what we have to do is find a location that matches the photo.

06:06

We'll collect photos of the area taken from ground level and try to find it.

06:11

Or we'll look at the angle of the sunlight and the shape of the shadows to figure it out.

06:17

You have to get creative.

06:22

The original images and 3D data are not enough

06:25

to determine the location and positioning of buildings.

06:30

So Watanave contacts the original posters

06:34

and asks them where the images were taken.

06:37

He then explores the area on a digital map, looking for similar building shapes.

06:44

When he finds a match,

06:46

he adjusts the angle and size of the image as he maps it to the location.

06:50

It's a time-intensive, painstaking process.

06:55

If it's a single building, you don't know anything about its surroundings.

07:00

Figuring that out can take an hour or even half a day.

07:05

I might post it to Twitter, asking if anyone knows the location.

07:10

Sometimes someone will be able to tell me where it is.

07:14

Other times someone will correct me and suggest that it's actually another location.

07:19

In that sense, this project is a collective effort.

07:23

This is the Russian cruiser Moskva,

07:26

the flagship that led the naval attack on Ukraine.

07:31

On April 14th, 2022,

07:33

Russia acknowledged that Moskva had sunk,

07:37

attributing its fate to stormy seas.

07:41

Ukraine, however, claimed that it had sunk the ship with cruise missiles.

07:46

It wasn't immediately clear what had been the cause.

07:51

The sky was overcast on the day in question,

07:55

which meant satellite images were not of much help.

08:02

So Watanave began analyzing images

08:04

taken by Synthetic Aperture Radar or SAR,

08:08

which is able to see through clouds to the water's surface.

08:12

It allowed him to find inconsistencies in Russia's story.

08:18

I was searching through SAR data and sure enough, it had captured images of Moskva.

08:23

This is about 190 meters long, which is the size of the warship.

08:30

There were no other objects that size.

08:36

There's strong evidence that this is Moskva.

08:40

This is a photo that they say was leaked from a Russian source.

08:44

It shows the sinking ship, taken from another ship that was right in front of it.

08:51

The SAR has also detected it.

08:53

Here's the smaller ship right here.

08:57

If it were stormy conditions,

08:59

there's no way these two ships would be so close to each other.

09:04

Russia continues to claim that it sunk in a storm.

09:07

But this has been exposed as a lie thanks to SAR,

09:11

which can penetrate the clouds and capture what's happening on the sea surface.

09:19

Watanave's fascination with digital technology began with video games,

09:24

which became popular in the 80s as he was growing up.

09:29

I loved the type of games that put you in an imaginary world,

09:33

where you went on quests and got into battles on your way to an end goal.

09:39

There were rivers and roads and even deserts.

09:42

The idea that there was this virtual world inside the console

09:46

and that you could go on these journeys was so thrilling to me.

09:52

For the longest time, I wanted to be someone who designed those worlds.

09:58

Watanave enrolled in the architecture department at a university

10:02

in order to study spatial design.

10:05

While in school, he also worked for a major game developer.

10:10

He designed cities and buildings for video games.

10:16

After graduating, he started his own video game development company.

10:21

But success evaded him.

10:26

My skills were useful for designing backgrounds and spaces.

10:30

But when you're making a video game,

10:32

you have to think about ways to get the player immersed and playing for many hours.

10:37

And I wasn't very good at that.

10:41

That's a fatal flaw for a game developer.

10:46

A video game company run by someone with little interest in entertainment

10:50

isn't going to work out.

10:52

So my business was unprofitable. It was not a success.

10:59

Around that time, Watanave came across a call for university lecturers,

11:04

and began his career as a teacher specializing in digital media.

11:12

He started a project in which he took video testimonies

11:15

of atomic bomb survivors from Hiroshima and Nagasaki

11:19

and archived them on a digital map.

11:26

Through the power of digital technology,

11:28

he hoped to pass on their stories to future generations.

11:36

In the near future, the generation that experienced World War II directly

11:41

will no longer be with us.

11:43

There are many people out there who want to keep the memory of war alive

11:47

for future generations.

11:49

They just don't know exactly how they can do that.

11:55

A-bomb survivors know their time is limited.

11:58

But in their daily lives, they're not suddenly going to find themselves in a situation

12:03

where they have to talk about their experience.

12:07

Through creating digital archives like these,

12:11

I feel like I've been able to show one example of how digital technology

12:15

can be used for the betterment of society.

12:22

In August 2022,

12:25

the Nuclear Non-Proliferation Treaty Review Conference was being held in New York City.

12:31

Watanave's research lab was in town exhibiting their digital archives nearby.

12:39

They invited atomic bomb survivors

12:41

to talk about the state of nuclear weapons and the need for peace.

12:51

There was one graduate student

12:52

who was studying nuclear disarmament at an American university.

12:57

They were watching with great interest.

12:59

It was their first time hearing from a survivor in person.

13:05

They told me that the experience gave them an emotional understanding

13:09

of the need for nuclear abolition.

13:12

I was glad to hear that.

13:16

Humankind has repeatedly, endlessly been at war.

13:22

Human beings themselves do not want to die in a war.

13:26

But regardless of who instigates it, the victims are ordinary citizens.

13:32

To me, it's important to convey just how tragic these experiences were

13:37

in as tangible a way as possible.

13:41

So that people feel that they don't want it to happen to them.

13:45

Or maybe they'll feel like they don't want it to happen to their family.

13:52

To that end, we have to make as many people as we can fed up with war.

14:00

(Do you have any words to live by?)

14:09

"Connect the past to the present."

14:13

The moment we feel like the past has nothing to do with our current lives, we forget.

14:19

That's especially true of memories of disaster.

14:24

To help ensure that people don't forget,

14:27

as someone who specializes in designing spaces,

14:30

I've tried to find ways to connect the events of the past to our present reality.

14:38

By showing how the past borders on the present,

14:41

by showing how they're contiguous, I want to prevent wars from happening in the future.

14:48

That's the goal of my work.
