Forbidden?
This massive mud volcano is equipped with communication cables.
Certainly, this video may be something else.
But it's not the right time.
Whoever wants to leave, they can go.
We'll cut the number of researchers who can't produce results.
I don't know anything.
It's impossible to move forward.
Remember I said that I went back to Tokyo after the Okinawan woman left me,
We had drinks together, right?
There was a person who didn't contact us and wasn't there
Why did you get on the 6K with my father?
Kamio-san.
I promised him.
I promised the people who were on the boat together.
Amagai-senpai and
Ishido-san
Please tell me
What happened to my father?
5 July 2005
Central Okinawa Trough Research dive
The last day
That's amazing!
Can you catch that shrimp?
That one, that one!
Yes!
I used to make mistakes. I was always scolded.
Even Amagai-san?
Besides, researchers think that submariners are
just people who pilot the 6K and don't know any better
How can that be?
I am also half a researcher, I can understand your feelings
But...
The safety of the 6K depends on us submariners.
So, no matter what people say, we have to keep our pride.
Would you like to operate the robot?
Yeah.
He's got a lot of talent, right?
I have underestimated him
By the way, I read the National Geographic some time ago.
If the Shinkai 12000 can succeed, can dive deeper.
Then we can know more things
12000?
If so, I'll win the Nobel Prize right away.
Don't be ridiculous.
All right, I'll take over
Okay.
This guy's really tough
We're running out of time. We should turn back.
Shinkai to Yokosuka, we're heading back.
Depth 1614, please advise.
Yokosuka, copy.
What's wrong with you?
Nothing. I'm fine.
6 July 2005 Port Naha, Okinawa Prefecture
I haven't seen you in a week. How old is your kid?
He'll be in elementary school next year.
He's the cutest kid around here, isn't he?
He's always making a lot of noise.
Amagai-san is the one whose daughter is looking forward to your coming home, right?
She's in middle school.
She's not as happy as she used to be when I come home now.
Amagai.
Do you have a moment?
What's up?
I want to talk to you about the mud volcano last time.
Then I'll get off the boat first
Okay.
Kamio, why don't you come with us?
We were contacted by Yokosuka Headquarters yesterday.
We got permission to dive to a massive mud volcano in the Nankai Trough.
Really?
That's right.
The communication cable under the sea is faulty and needs to be repaired.
The company will pay for the repairs.
6K will be used for the repair work.
What's going on? It's not a research study.
That's what the head office said.
But it won't take them much time to repair it.
I see.
All we have to do is conduct the dive?
Are we going to conduct a survey without permission?
That area is forbidden because they've laid communication cables on the massive mud volcano
Since last year, we've been unable to conduct research dives.
We may not be able to get another chance
So that's how it is.
When the government asks us to do something, we have to clean up after the private sector.
That's part of securing the budget.
Don't say that.
This time, I was informed directly by the leader of the Okinawa submarine research team.
And I immediately thought of you.
But the dive has to be conducted secretly on the way back to Yokosuka from the mother ship.
The Commander doesn't know
He doesn't
The mothership is also operated by a private company
The crew will be kept to a minimum.
And you will say you stayed on the mother ship to analyze the samples taken from Okinawa?
Are you up for it?
Yes
Let's take this chance
Kamio, I'd like you to be my second officer.
We have 15 minutes until departure.
Please leave, except for the crew.
Good morning.
Atsushi, where's your luggage?
I'll go back to Yokosuka by ship.
Do you still need to do research?
It's more time consuming to fly back.
What? We've booked a good restaurant in Naha and we were expecting to see you there.
What restaurant?
There's a cute girl named Mami.
She gave me her phone number a while ago.
Mami? She gave me her number too.
You? How is that possible?
You guys have fun, right? I'll go back next time.
Okay, let's go.
Give me her cell phone number.
No!
I'll see you at headquarters.
Give it to me!
Stop it, Kondo-san!
Atsushi-san!
Stop it! Stop it!
Let's go together.
Everthing alright?
Yes
But why are we surveying this mud volcano?
We've been submitting requests for surveys, right?
Even though we know there's a cable there.
Why are you laughing?
Have you ever heard of the universe in the deep sea?
The universe in the deep sea... I've heard some rumors.
I saw it on this mud volcano.
You saw it. Really?
In April 1998, before the cable was laid.
When the survey was over and we were going back to the ship.
I saw it through the observation window, and it was shining.
It was beautiful.
It was like a starry sky.
The other two crewmembers didn't see it, and the camera didn't capture it.
But I'm sure that's the universe in the deep sea.
Is that why we are going to that mud volcano?
From the characteristics of the light, it looks like a new deep-sea creature.
But no matter how deep you dive, you can't find it on other seabed.
I think maybe they only inhabit the large mud volcanoes in the Nankai Trough fault.
If there was no cable, I could survey whatever I want.
But now I can only use the data from the survey to make assumptions every day.
I don't get to go home much either.
After this dive is over.
Naoko will be relieved, right?
I had a fight with her in front of the entrance gate before I came to Okinawa.
Poor you
But I was able to concentrate on my research.
It's thanks to Naoko.
You're one to talk
It's true
She complained to me when I left the house.
That means she's been working hard for the family.
Usually I rely on her for everything, and leave everything at home to her.
So I have to prove that the universe in the deep sea really exists.
It's a kind of compensation and repayment to her.
Did Director Ishido ask my father?
At that time, Amagai-sempai was studying earth biology
Ishido-san was a researcher of underwater resources.
The two scientists exchanged ideas about the universe in the deep sea.
Excuse me.
I'm sorry for making you come here.
No, it would be impolite to ask you to come to Yokosuka.
I hate the sea breeze and the smell.
What do you think? If it's a good time to start using drones, let's do it.
Then let's go ahead and do it
It's the natural trend
They keep insisting we need manned submarines for deep sea research.
What a joke!
JAMSTEC hasn't changed for the last 10 years
7 July 2005
Nankai Trough
Amagai-san!
We're almost there.
Amagai-san!
Are you okay?
Do you need these?
I'll call a helicopter immediately
We'll be back in the afternoon.
You don't have to make a fuss.
What are you talking about? You're in such a bad shape.
Do you still want to dive?
You shouldn't
Just take the boat back to Yokosuka.
I'm really fine. I'll be fine after I take my medicine.
But...
If I don't go today, I don't know when I'll be able to go next time.
Okay, let's go.
I should have stopped him at that time.
Kamio, what's the voltage of the mother ship?
Yes!
What's wrong with you? I'll leave you behind if you're still dreaming
I'm sorry.
108 volts.
Good.
Dive Time
I'll never get sick of seeing it
What?
Marine snow is mostly biological debris that originates from the top layers of the ocean and drifts to the seafloor, providing a primary source of energy for animals in the deep ocean.
Marine Snow
My daughter's name is named after marine snow
Amagai Miyuki
"Deep Snow" (Miyuki)?
It's the snow that falls in the deep sea.
深=Deep 雪=Snow
Isn't that a good name?
Shinkai to Yokosuka
Depth 4000
The sling is ready
We are ready to dive deeper
(Understood)
Atsushi.
This is a secret dive. Don't turn on the deep sea camera.
OK?
Got it
Is this OK? For personal research.
Yes.
Shinkai to Yokosuka. Checking-in
No abnormalities
Depth 4085
Submarine visibility 5 meters
Water temperature 2.5, Water current speed 320.4
Please advise
(Understood)
Shinkai copy
I'm surprised you're so engrossed.
A large mud volcano is 300 meters to the northeast.
Okay, let's go.
Ishido-san!
What's wrong?
Nothing, nothing.
Are these whale bones? It's the first time I've seen it.
When a whale dies and sinks to the bottom of the sea.
An ecosystem can be formed directly on the body.
That's a good milestone.
Is it around here?
We've been here before, right?
Yes.
Shinkai to Yokosuka.
We've arrived at the mud volcano. Please give us directions.
(Understood)
That's strange.
What's wrong?
Where the hell is the communication cable?
It's buried in the mud, right?
But the metal detector is not responding.
You're sure you're in the right place?
Yes, this is it.
Shinkai to Yokosuka, we can't observe the cable.
Please tell us where it is.
Shinkai to Yokosuka, what does the UQC inspection screen say?
Amagai-san?
We've lost communication.
Ishido, why can't I see the cable?
I don't know.
The layout drawing is wrong.
Either that or it was washed away during a volcanic eruption under the sea.
Whichever it is, let's move on.
It's dangerous not to be able to communicate with Yokosuka.
And it's against the rules.
Either way, let's try not to waste this trip?
At least find the cable and then go.
But...
Let's go, Kamio.
If we can't find it, you can release the ballast and surface
The universe in the deep sea is just ahead.
I got it.
At a depth of 3700, we should be reaching the top of the mountain
I saw the universe in the deep sea near the top of the mountain.
We're about to see the universe in the deep sea.
Amagai-san, is there something up ahead?
What is it?
A rock?
There was nothing like this before.
Go closer.
Turn on the lights.
Yes
It's a military aircraft.
Is it the one that cut the cable?
But the metal detector didn't respond either. It's strange.
What's going on here?
I don't know.
Ishido, what do you think?
Do you know anything?
What is the purpose of the dive?
Ishido!
That's not good.
What's wrong?
It's coming!
Full speed ahead!
We can't make it!
I know. Full speed ahead.
It's at maximum
Can't turn anymore
Surface?
We can't
It's coming
Hold on!
What's going on here?
I do not know
Anyway, let's surface first
Yes, sir.
What's wrong?
Maybe it's stuck in something.
Amagai-san, what do we do?
The main battery is broken.
Is it bad?
I have a backup battery.
How long will it last?
About 20 hours.
Turn off all systems that don't need power, and save power by turning off all the lights.
Yes.
Dive Time
What to do
Are you both okay?
Sorry, I didn't make it out.
It's okay.
Ishido.
What is the real purpose of this dive?
Answer me.
The real purpose of this dive.
To confirm the condition of the downed military aircraft.
We shot down a U.S. test plane.
Under a secret government treaty.
The incident was covered up as an accident.
JAMSTEC was also forbidden from the area.
The cable thing was just an excuse.
Why are you involved in this?
Before I left Okinawa, I was called by a senior government official to talk to him.
Because I know the area best.
What kind of deal did you make?
Ishido.
Why did you choose Amagai-san?
I thought there were other submariners.
Amagai-san is...
Stop! It's too late.
He's the only one I can trust.
The mission is over.
Let's call for help.
The communication was cut off by the people above.
So as not to leave any trace in the call log.
It's almost time for the communication system to be restored.
Dive Time
Yokosuka to Shinkai. How's the UQC?
This is researcher Ishido.
The job was completed successfully.
Yokosuka understands.
Thank you for your hard work.
However, the submarine can't float.
Please prepare for recovery immediately.
Yokosuka understands and will proceed immediately.
Ishido made a deal with Kikuya before the dive.
He confirmed the status of the military aircraft for Kikuya.
Accordingly, Kikuya had to transfer him to a civilian research institute in the United States.
During the dive, a crew of Kokukai heavy industries with Kikuya's backing would be available.
to pilot the craft.
Now I think it was all designed from the beginning.
So, Jinnai-san replaced the commander.
He seemed to be the head of the maintenance department at that time.
The relationship with Ishido also began at that time.
Let's turn on the main power again and try.
It's not working
What's the status now?
Maybe the drainage system is clogged with mud or jammed by something.
I can't see any obstacle in the front view.
Let's start the thruster.
Still no good
Will the vertical thruster work?
It doesn't look that easy, but we can only try.
How long will it take?
I don't know.
It seems that we can only let the thruster keep rotating.
I just don't know how long the battery can last.
Dive Time
Ishido-san.
What the hell were you thinking?
This is all because of you.
Kamio, don't waste oxygen.
Pass me the tools.
It would be nice to have a universe in the deep sea
That's why I'm here
The universe in the deep sea is probably related to earthquake prediction.
Predicting earthquakes... is that possible?
The last time I observed an earthquake, it happened right after.
Solve the mystery of the deep ocean universe,
maybe we can figure out how earthquakes happen.
That's amazing.
That's why we can't give up yet.
I really want to dive even if I have to lie
And I got what I deserved.
It can't be helped, just smile.
It's already depressing enough with three uncles together
Why does Amagai-san want to be a researcher and a submariner at the same time?
Why are you asking this all of a sudden?
I just think that to understand the universe in the deep sea.
Isn't it faster to concentrate on research?
Researchers can only dive once a year.
But a submariner can dive more than seven times a year.
Is this determined by the number of dives?
Even if it's one more dive, I want to dive.
I want to use my eyes to find the universe in the deep sea.
Besides, if someone develops a new field.
Maybe the organization will change too.
What's wrong?
Nothing.
Amagai-san, where's the medicine?
I don't have it.
What's wrong?
Amagai-san is sick.
Why didn't you tell me?
It's okay.
I'm just a little sick.
Kamio.
How long did I sleep?
About an hour.
Are you OK?
How's the power?
Considering the time it takes to float, there's not much left.
I'm scared.
I don't want to die.
What are you talking about?
I want to dive with you guys again.
Next time...
Let's dive to the bottom again.
Listen, the 6K is safe.
No one has died on a 6K.
So...
I won't die on the 6K.
Got it?
Amagai-san
Battery
It's still holding up, right?
Can you give me the phone?
I'd like to leave a message.
What are you talking about? There's only a little bit left.
Kamio.
Here.
I'm sorry.
A bit longer
Just a little bit longer
and I would have been able to find
The universe in the deep sea
It's there
There it is
Hey!
I've got it!
What is it?
Atsushi!
Pull youself together!
Atsushi, come on
What's wrong?
Hey!
What's wrong?
Amagai-san!
I've got it.
It's there.
It does exist.
Miyuki
I'm sorry.
I want you to
to see the world
of the deep sea
universe
Amagai-san
Wake up
Amagai-san
Miyuki is waiting for you
Amagai-san, get up!
Amagai-san!
Wake up!
After that, before the submarine surfaced.
The whole process was just as Amagai-senpai had predicted
The mud volcano collapsed.
The earthquake happened at that time.
Maybe we got lucky too.
8 July 2005 Morning
You knew about it beforehand
That he was sick?
Yes
Before the dive.
He collapsed in the room.
I tried to stop him.
But Amagai-san insisted on diving
He asked me to keep it a secret.
So
I...
I won't forgive you.
Ishido-san.
Atsushi-san,
didn't die on 6K,
right?
The 6K is safe.
No one can die on a 6K.
9 July 2005 YOKOSUKA HEADQUARTERS RETURN TO PORT
I understand the situation in general.
I'm sorry to hear about the death of the submariner.
But he hid his condition, so there's nothing we can do about it.
Regarding this matter,
please take care of it.
I've been hiding it from you.
I'm sorry.
Do you hate him?
Kamio-san?
How could I?
Ishido was transferred to a research institute in the United States.
I'm afraid...
Kikuya arranged it secretly.
Why?
Why didn't he tell me?
Ishido-san.
On the day of my father's funeral.
He let me hear
my father's last words.
I wanted you to see it.
the deep sea
universe
My father
why did he have to sacrifice his own life?
Because of a plane that sank to the bottom of the ocean?
Or was it because he wanted to hide his illness?
Or was it because he was searching for the universe in the deep sea?
I don't know.
But...
Whatever my father was looking for,
I want to see it with my own eyes.
I...
I want to see the universe in the deep sea
Welcome
