NARRATOR: Japan is a land rich with ancient mysteries.

WILLIAM HENRY: In Japanese history there's been hundreds

of sightings of mysterious lights

that fly in the air and then also enter into the oceans.

DAVID CHILDRESS: We have these underwater cities there

that have strange energy associated with them.

GIORGIO A. TSOUKALOS: You have these statues that look

eerily similar to modern-day astronauts.

NARRATOR: And recently, Japan has also become known

as a hot spot for unidentified aerial phenomena.

The Japanese government actually

issued a policy to shoot down UFOs.

NARRATOR: Could it be that the entire history of this island nation

has been directed by extraterrestrial visitors?

Ancient aliens brought Japan into the modern world.

NARRATOR: At 2:46 p.m., the region is rocked

by a 9.0-magnitude earthquake--

the most powerful to ever hit the island nation.

A little over 30 minutes later

a tsunami with 130-foot-tall waves smashes into the area.

Among the hardest hit locations is the nearby

Fukushima Daiichi Nuclear Power Plant.

The power was cut out.

The cooling system went down, and just this enormous

amount of radiation went into the atmosphere.

NARRATOR: Authorities evacuate the region and order a small team to stay

behind to prevent a larger catastrophe from occurring.

But days later,

videos posted on social media

show these workers

were not alone.

TSOUKALOS: The video that we have of Fukushima,

you see these bright golden orbs,

many of them flying in formation.

And of course, with all these orbs that we see,

we know it's something technological.

NARRATOR: Curiously, almost exactly ten years later,

on February 13, 2021,

the region is rocked by another powerful earthquake.

Over the next two months,

mysterious yellow orbs are observed

hovering above the Fukushima nuclear power plant.

TRAVIS TAYLOR: Recently, Japanese people

have reported seeing UAPs in the region

near the Fukushima reactor meltdown.

It radiated a major part of Japan,

but for some reason people are seeing

UFO activity in the area.

NARRATOR: What are the mysterious lights

that have been seen flying

over the Fukushima Daiichi Nuclear Power Plant?

It's a question that prompted

the Japanese government to take action.

On May 28, 2024, the Japanese parliament

announced the formation of an investigation

unprecedented in modern Japan.

In 2024 the Japanese government issued a mandate for

a bipartisan 80-member panel

to investigate the UAP situation.

Now, why did they do that?

I think mainly, the Japanese people were

getting concerned with the things flying over

their infrastructure and wanted to take precautions.

(speaking Japanese)

(translated): I have been deeply involved

and I participated in the first

general meeting and the second one as well.

I believe that the government is taking the UAP issue

more seriously from the viewpoint

of national defense or national security.

NARRATOR: Government officials have refrained

from commenting on the events at Fukushima

and other UAP sightings in Japan.

But Defense Minister Yasukazu Hamada

recently issued radical new protocols

for Japan's Air Self-Defense Force in the event

of encountering UFOs in highly restricted areas like Fukushima.

The Japanese government actually

issued a policy, a guideline, to actually shoot down

UAPs if they don't leave the areas

over sensitive infrastructure like a nuclear reactor facility.

So this shows that the government of Japan,

and the military of Japan,

take UFOs and UAPs very seriously.

And that this is something that, you know,

they are intensely interested in.

NARRATOR: But while the Japanese government

has only recently begun

its first official UFO investigation,

the people of Japan

have shown a strong interest

in unidentified flying objects for decades.

Aviation journalist Yusuke Matsumura

is leaving his house early in the morning

when he spots a metallic disc hovering in the sky.

Fortunately, Matsumura is carrying a camera,

and takes the first ever photograph of a UFO in Japan.

Inspired by his sighting, Matsumura created a group called

the Cosmic Brotherhood.

When the UFO craze really began in the 1950s,

in Japan it was quite sedated.

Reports were filed and basically forgotten

as something a bit strange-- there was a weather balloon

in the vicinity at that time,

maybe it was a Korean spy plane.

There was one exception, which was

the Cosmic Brotherhood Association.

And that was founded by Yusuke Matsumura.

And he said, "No, no, no. All these UFOs are alien craft."

In '64, the Cosmic Brotherhood Association started to build

an altar in Biratori in Hokkaido,

which is an absolutely massive thing as their place of contact.

NARRATOR: The Cosmic Brotherhood built this altar as a place

to communicate with extraterrestrials,

and they selected the mountain

because it was believed to be the landing spot of a god

who traveled to Japan thousands of years ago.

They chose Biratori because that was where the god Okikurumi

had either come down to Earth or left Earth again.

Which sounds like an ancient people

trying to describe a first contact.

So it seemed like, you know, a good spot.

HENRY: The Cosmic Brotherhood organization

emerged in Japan with a fascinating theory.

They maintained that the very spot where

Okikurumi is believed to have landed was considered to be

a meeting place to meet extraterrestrial visitors.

NARRATOR: 15 years after the Cosmic Brotherhood

was formed, Japan was electrified by

a series of extraordinary incidents that, to this day,

remain the country's most famous UFO events.

13-year-old junior high student Michio Seo

observes a very small and peculiar object flying

above a rice field, zigzagging back and forth.

Later that night, he and several friends find the object again,

only now it's emitting a pulsating silver light.

(speaking Japanese)

(translated): It's about this big, just about.

A small object shaped like a doorknob.

And this thing was flying.

Finally, it fell into a rice paddy.

So they caught it and then they went home

and the people at home saw it.

NARRATOR: The boys reported that the mysterious

silver object was less than

eight inches in diameter and weighed only three pounds.

The bottom surface was perforated with an array

of tiny holes and imprinted with curious designs.

But before it could be further examined,

the object disappeared again.

(speaking Japanese)

(translated): There was more than one witness.

A number of junior high school students saw the incident,

and it definitely happened.

NARRATOR: Another sensational incident

involving schoolchildren

occurred in Japan just three years later,

and this time it included

a face-to-face encounter with an alien entity.

(speaking Japanese)

(translated): In this incident,

a UFO landed and an alien appeared from inside.

Two elementary school children encountered the alien,

and one of them was tapped on the shoulder by the alien.

Later, when a scientist analyzed the soil where it landed,

they found a radioactive substance, phosphorus-32,

which cannot be found in nature.

The fact that phosphorus-32 was produced

is evidence that there was an object that emits radiation.

So, there was definitely an incident.

NARRATOR: While reports of UFO sightings throughout the 20th century

received little attention from the Japanese government,

recent encounters with unidentified aerial phenomena

have sparked a call to action.

And Japan is now at the forefront

of investigating UFO activity.

But why does Japan seem to be experiencing such

an increase in unusual sightings?

Perhaps the answer can be found by examining ancient figurines

that are believed to depict otherworldly beings.

NARRATOR: American archaeologist Edward Sylvester Morse

is excavating an ancient shell mound

when he unearths unique cord-marked pottery.

The artifacts are among the oldest ever discovered

in Japan and Morse uses the term "Jomon,"

meaning "cord-marked" to identify the mysterious

ancient culture that made them.

The Jomon are one of the main Indigenous peoples

of Japan, historically.

They dominated the archipelago

from about 15,000 BCE to 300 BCE.

And not much is known about them.

It's a fairly mysterious or poorly understood culture.

What we know about Jomon culture is

restricted to material culture.

It's the stuff that we dig up from the ground.

The striking thing about the Jomon people

and Jomon culture is that it is unusually

advanced for what we would expect

for a hunter-gatherer group.

Jomon pottery is very elaborate and the idea

that a "hunter-gatherer" group of people

would even develop pottery

is itself-- kind of flies in the face of

traditional anthropological distinctions

between hunter-gatherer and agriculturalist people.

NARRATOR: The Jomon's most mysterious artifacts

are small statues depicting strange-looking figures

that are referred to as the Dogu.

The Dogu statues are one of the smoking guns

of the ancient astronaut theory.

You have these statues that look like some type of beings inside

of a pressurized suit completely hermetically sealed.

You have these helmet-type enclosures on top of their heads

with giant goggle eyes.

And an engineer by the name of Vaughn Greene

wrote a book and proposed

that what we're looking at here is a modern-type space suit.

He compared and contrasted modern-day

space and diving suits with these Dogu statues.

And for 30 points they matched exactly.

And what's so interesting too is that the correlation

between the Dogu figures and their mythology is

that these beings descended from the sky.

NARRATOR: Although the Jomon people left no written records,

it is believed that they developed Shinto,

Japan's Indigenous religion.

Shinto beliefs hold that thousands of gods

descended on Japan from the sky.

STEAVU: The Shinto religion is the only Indigenous

Japanese religious tradition.

Shinto translates as "the way of the gods"

or "the way of the Kami,"

the Kami being these divine beings or gods.

Kami in the Japanese native religion of Shinto

can take on a variety of forms.

This included the heavenly Kami who are

the ones who live in heaven,

and earthly Kami who live in the Japanese archipelago.

STEAVU: These heavenly Kamis intermingled and

procreated with the earthly ones

and eventually this formed the human race as well.

So, from the moment in which humans appear,

this is a different era in this Shinto cosmology,

which is known as the era of humans.

And this is when we have a kind of hybrid race,

a mixture of human and divine Kami stock.

The idea that a divine race is breeding with humans

is fundamentally the basis of Japanese religion.

It's the basis of Shinto.

NARRATOR: According to the Shinto tradition,

before the establishment of the Japanese emperor,

the island nation was ruled by gods.

GRAHAM PHILLIPS: The first emperor was thought to have reigned around 700 BC.

The period before that was known in Japanese mythology

as the Age of the Gods.

The reason is because it was said

that the gods walked amongst humans,

which is very similar to the ancient Egyptian mythology

where the Pyramid Texts

describe the early period of

Egyptian history as the golden age of the gods.

NARRATOR: As told in the ancient Japanese texts, the Kojiki,

a man named Jimmu, a divine descendant of the Sun goddess

Amaterasu is chosen by the gods to be Japan's first emperor.

But in order to take the throne,

Jimmu must journey from the southern island of Kyushu

to the Yamato Province,

roughly 500 miles to the northeast,

navigating mountainous terrain

and battling warlords along the way.

What's so fascinating about the ascent of Jimmu

to the throne around 600 BC is the fact

that this is, in my opinion, one of those legends

that perfectly fits into the ancient astronaut theory

because it involves misunderstood technology

and a celestial visitor.

It is said that Jimmu was guided by

a three-legged crow called Yatagarasu.

And this so-called crow

was given to Jimmu by Amaterasu--

the first goddess that descended from the sky.

PHILLIPS: The stories are that this

three-legged crow was huge

and it was surrounded by a white globe of light.

(crow cawing)

TSOUKALOS: The ancient astronaut theory

tries to understand

what it is our ancestors tried to

explain to us because one thing is crystal clear:

There is no three-legged crow, so the question then is,

well, why, how did that come about?

This to me sounds like some type of an aerial

drone technology with which to survey the ground

that our ancestors witnessed

without knowing anything about technology.

NARRATOR: Does the story of Jimmu reveal

extraterrestrial intervention in ancient Japan?

Perhaps further clues can be found

by examining mysterious relics of immense power

that the imperial family

has hidden from the public for centuries.

NARRATOR: Japan celebrates the ascension of its new emperor

Naruhito, who takes the throne at age 59.

He is the latest emperor in the longest running

royal family on earth.

Japan's imperial family known as the Chrysanthemum Throne

dates back an incredible 2,700 years.

Most dynasties, if they last several hundred years,

that's a good run.

Monarchies do not last 2,700 years,

so it's extraordinary

that Japan's imperial family has lasted this long.

NARRATOR: The elaborate ceremony involved a series of sacred rituals,

but the most important of these events

is also the most mysterious.

In the state room of the Imperial Palace,

the new emperor was presented

with several boxes that are filled

with treasures so secret,

they've never been seen in public.

They contain Japan's imperial regalia.

STEAVU: The imperial regalia are a set of three divine treasures.

The first one is a sacred sword.

The second is a sacred mirror, or divine mirror.

And the third is a curved jewel, which is also divine in nature.

TSOUKALOS: They're being kept under lock and key because

not only are they sacred, but some people have proposed

that they are of otherworldly origin.

And it's accepted as fact.

HENRY: These sacred items

are the ultimate treasures of Japan.

In fact, at the end of World War II,

Emperor Hirohito was deathly afraid that should

Japan be invaded, these sacred treasures

could ultimately be possessed by

the United States Army or some other invading power.

And this was said to be one of the reasons why he surrendered

to General MacArthur, was to actually protect these relics.

NARRATOR: According to legend, the imperial regalia

are gifts from the Sun goddess Amaterasu

that were passed down to Japan's first emperor, Jimmu,

who was her direct descendant.

Legend has it that each of the three objects

possess supernatural powers.

The most mysterious is the curved jewel.

The jewel is a big question mark.

We don't really see it referred to in-in other myths.

It's not clear what its purpose or provenance is.

CHILDRESS: These three objects are held in boxes.

And ancient records in Japan say that there was an emperor

who decided to open one of these boxes with the jewel in it.

And that a white smoke started coming out of it.

And so he ordered it closed again.

So you just have to wonder, what's in this box?

Could it be some extraterrestrial device

that has an energy coming out of it?

NARRATOR: While very little is known about the jewel,

much more has been written about the mirror,

which is said to provide a direct connection

to otherworldly beings.

Amaterasu's mirror was supposedly given to the daughter

of the 11th emperor of Japan, Yamato Hime.

And she wandered Japan for 20 years looking

for the right place to

build the shrine that the mirror would be held in.

MATSUURA: She came to a spot in what is now Mie Prefecture.

And there was some kind of

communication through the mirror where,

this is where the Amaterasu

wanted her shrine to be built.

And it was built.

To this day it's still there,

the Grand Shrine of Ise.

NARRATOR: In addition to communicating with Amaterasu,

the mirror could also be used to see what was

happening worldwide in real time.

(speaking Japanese)

(translated): I think this is probably a tablet.

Using something like FaceTime communicating with the gods.

But it only works for people who have been chosen to use it.

(speaking Japanese)

NARRATOR: Could it be that Amaterasu's mirror

was an extraterrestrial device

similar to what we know today as a tablet?

Ancient astronaut theorists say yes,

and suggest further evidence that the imperial regalia

contains advanced alien technology can be found by

examining the third object, the sacred sword.

STEAVU: Yamato Takeru, the 12th emperor of Japan,

famously discovered that the sword had a magical power.

He was trapped by a treacherous warlord,

who intended to eliminate him by burning him

alive in a field of grass.

And when Yamato Takeru started hacking away at the grass to

remove the fuel from the fire, he noticed that the swings

of his swords were actually producing wind

and pushing the flames in the opposite direction.

So he used this magical power that he discovered

to actually fan the flames in the direction

of the warlord and his troops and burn them.

The last time this sword was viewed publicly

was in the 1600s.

A priest named Masanou had gathered some other priests

and they went to the shrine where the sword was located,

intent on doing repairs.

STEAVU: They happen to open the box in which the sword is contained

in order to better clean it and maintain it.

And he describes this sword as being made

of a very brilliant white metal,

almost supernatural type of metal.

And it didn't show any signs of age,

or rust, or any decay on it.

Everybody around the sword

developed some kind of affliction and died soon after

opening it and then looking at it.

But one priest survived to report what happened.

TSOUKALOS: This is interesting to me, because there is a connection

between celestial objects and people dying.

For example, the Ark of the Covenant comes to mind.

Whoever did not know how to operate the Ark died

of unknown conditions

and the unknown conditions are

boils on the skin, the falling out of fingernails and hair.

Well, what unknown disease is that?

It's radioactive fallout.

That's the only way that this really can happen.

So, is it possible that there are potentially

radioactive extraterrestrial artifacts here on Earth?

The answer is a resounding yes.

NARRATOR: Could the closely guarded ancient relics

that have been hidden from the public

for thousands of years be extraterrestrial in origin?

And if so, have they been used over the centuries

to keep the Japanese royal family in power?

The true nature of the imperial regalia

may only ever be known to the emperor,

but ancient astronaut theorists suggest other artifacts

that point to Japan's extraterrestrial past

are hiding in plain sight.

NARRATOR: One of the greatest mysteries of the ancient world

is why enormous stone structures

appear on nearly every continent.

And at one time, megalithic monuments

could be found throughout the islands of Japan.

Not many people know this, but ancient Japan was strewn

with megaliths and henges.

The ancient peoples of Japan had these stone monuments

all over the place.

During the samurai era, which was war all the time,

most of them were ripped up and used to make castle walls

and castle foundations.

Some survived because they're so weird.

NARRATOR: Perhaps the most curious,

and awe-inspiring, of Japan's megaliths

is Ishi-no-Hoden,

a giant stone monument near Osaka carved out of the bedrock

and believed to date back 16,000 years.

The Ishi-no-Hoden megalith is

sometimes called the heavenly floating rock.

It's huge, probably around 500 tons.

It's about a 20-foot square cube that has been

built in such a strange way that underneath it,

there's a base that holds it up above the ground,

so it appears for all the world to be hovering in the air.

It is said to commemorate

a god that once came to Earth in a huge

cubic-shaped object and landed somewhere in that area.

TSOUKALOS: In Japanese mythologies and legends,

it says that long ago

physical gods were amongst our ancestors

that had the capability of flying or of flight.

So, the fact that they used this water mirror underneath

this stone to show as if it is hovering and floating

in the air, to me, is to signify flight.

NARRATOR: Curiously, Ishi-no-Hoden is not the only Japanese megalith

that appears to document

an ancient extraterrestrial visitation.

STEAVU: The Masuda-no-Iwafune, which translates to

"the stone ship of Masuda,"

is another megalithic structure.

This is an even larger granite megalith

30 feet across and about 20 feet in width

and 15 or so in height that has a central depression or trough.

PHILLIPS: This monolith is said to have marked the Earth side

of a so-called floating bridge

that connected Earth to the heavens.

Now, what is a floating bridge?

It's described as something that the gods descend in.

STEAVU: There is a story in Shinto annals

about the bridge that unites

the earthly realm with the heavenly realm

collapsing and falling onto the Earth.

So, these megaliths, according to some,

are the remnants or the building blocks of this

celestial bridge that has since collapsed.

This floating bridge sounds exactly like the bridge

Bifrost of the Nordic tradition upon which the gods would come

and go from the Earth into the heavenly realms, or Asgard.

This suggests that the same people

are descending to these various cultures.

NARRATOR: Might the Ishi-no-Hoden

and Masuda-no-Iwafune megaliths

have an extraterrestrial connection?

Ancient astronaut theorists say yes,

and suggest the most intriguing of Japan's

megalithic structures can be found

beneath the sea.

On the western tip of the Japanese archipelago

lies the tiny island of Yonaguni.

In 1986, scuba divers exploring

just off the coast make a shocking discovery.

60 feet beneath the ocean surface,

they find a massive rectangular structure roughly 328 feet long

and 196 feet wide.

It has since become known as the Yonaguni Monument.

PHILLIPS: The Yonaguni Monument is huge,

and it looks for all the world like an artificial construction.

There are steps.

There are what appear to be columns

and all sorts of geometric formations

that seem to have been artificial constructions.

Professor Masaki Kimura spent ten years

examining the structure with divers

and the most sophisticated equipment at the time,

and he was convinced beyond any doubt

that it was an artificial formation.

TSOUKALOS: Yonaguni boggles the mind

because at some point that was a land bridge that existed

when the water levels were lower and that means

we're talking around the last ice age,

which was 10,000 or so BC.

Now, that means that back then

a culture must have existed

to carve Yonaguni the way it appears today.

NARRATOR: For ancient astronaut theorists, the possibility

that the Japanese were building

sophisticated megalithic monuments

as much as 12,000 years ago

is highly significant

because in numerous cultures around the world,

there are ancient stories about advanced civilizations

that inhabited the Earth right around that time.

If the Yonaguni monument is as old as we think it is,

then this aligns this Japanese site with other sites

in the Pacific, most notably Lemuria and Mu,

which are thought to be pre-flood civilizations

that had achieved an advanced state of civilization

but were destroyed by cataclysm.

NARRATOR: Could Yonaguni have been part of an advanced, prehistoric

civilization that was submerged at the end of the last ice age?

And did some of the survivors populate Japan?

Perhaps further clues can be found

by looking at the ocean region where Yonaguni lies,

which is a hot spot of mysterious activity called

the Dragon's Triangle.

NARRATOR: The Japanese freighter Kaiyo Maru

is en route to California when suddenly,

the ship's instruments begin to fluctuate wildly.

Just after 8:30 p.m., the crew watches in astonishment

as a huge elliptical-shaped object

suddenly appears on their radar.

The mysterious craft,

which is larger than a supertanker,

circles them for several minutes,

before it makes a sharp turn and heads straight for them.

(speaking Japanese)

(translated): A large object on radar approached the ship

and passed overhead when they thought

it was going to hit them.

This was reported in newspapers at the time,

especially in a scientific magazine called Nikkei Science,

so it is known as a very famous incident.

NARRATOR: This is just one of thousands of encounters reported

in a part of the Pacific Ocean

that stretches south of Japan down to Guam

and the area of the Yonaguni Monument.

It is known as "the Dragon's Triangle."

1,500 vessels have disappeared

in the Dragon's Triangle.

Planes have disappeared in the triangle.

What happened? But more important, why?

Beginning in 1950, the Japanese government was so concerned

about this area

that they sent a research ship out

and it too vanished with 22 crew and nine scientists aboard.

TSOUKALOS: Is it possible that some ships have disappeared

because of calamities and, you know, accidents?

Sure.

But is it also possible

that perhaps some of these boats disappeared

due to extraterrestrial interference?

The answer to that is a resounding yes as well,

because there are stories of other ships witnessing

things happening with lights

and objects hovering over the ocean and things like that.

NARRATOR: Disappearances and strange sightings

have not only been reported in this area in modern times

but going back centuries.

HENRY: Adding to the intrigue of the Devil's Triangle

is the fact that in Japanese history there's been

hundreds of sightings of mysterious lights

that reach out from within the sea

and absorb or sink these ships.

Today we think of these as submersibles

or transmedium craft that have the ability to

fly in the air and then also enter into the ocean.

CHILDRESS: You have to wonder if there's some underwater UFO base.

And there's some hyperspace portal going on, or vortex.

NARRATOR: Is it possible that hidden beneath the Pacific Ocean,

somewhere within the Dragon's Triangle,

there is an extraterrestrial base?

Curiously, there have also been reports

of sea monsters in this area dating back centuries.

And the Dragon's Triangle was the location

of Japan's most famous historical UFO encounter,

known as the Utsuro Bune sighting.

CLEMENTS: There's a really odd story from 1803 in Hitachi

where a woman washes up on shore on the beach

in a very strangely shaped boat.

And when she comes out of the boat,

she has white or pink skin.

She has red hair with white tips,

and she doesn't speak Japanese.

And during this time, Japan is closed to the outside world,

and it's a capital offense to interact with foreigners.

So the people on the shore

were absolutely terrified of this woman.

They didn't know what to do.

They put her back in the boat and they pushed it out again.

And they reported it to the local lord,

and they referred to her ship as the "utsoro bune,"

"the hollow ship."

There are at least 11 different

people who came forward and documented it.

They drew pictures of it.

There's paintings of what

the ship looks like and what happened.

HENRY: Her craft looks exactly like a flying saucer,

a contemporary flying saucer.

But this is in 1803, suggesting that this is one

of the most extraordinary UFO sightings, perhaps not only

in Japanese history but in all human history.

NARRATOR: Does the Dragon's Triangle provide compelling evidence

that an alien presence has existed on Earth

in this area of Japan for thousands of years?

Ancient astronaut theorists say yes,

and suggest further evidence can be found

by examining a sensational event that happened

in Tokyo Bay, involving the U.S. military.

NARRATOR: U.S. Naval officer, Commodore Matthew C. Perry,

arrives with his American fleet

to force Japan to end its policy of isolation.

American ships were sent to Japan to try and get Japan to

open up to the world because it had been pretty much

closed off for centuries

during the time of the Shogunate,

the military rule in Japan.

The emperor had continued to rule

but only really as a puppet ruler.

NARRATOR: The night Perry's fleet arrived in the bay,

both the Americans and the Japanese

were awed by a spectacular sight.

PHILLIPS: Perry, he wrote a log,

and he said that while they were in Tokyo Bay

a strange, glowing blue object

was seen in the skies that hovered over the ships.

So bright was it at night,

that it literally lit up all the ships.

Underneath it was what he wrote and described

as like the sparks from a rocket.

And it hovered around the skies and eventually

descended into the water.

What we have in the case of Commodore Perry

in Tokyo Bay in 1853 is a sighting that lasted

four hours of a gigantic blue sphere

up in the sky with a red wedge tail.

What the heck is that?

And it just stood there

illuminating the entire Tokyo Bay.

NARRATOR: Perry's mission not only led to the opening up

and modernization of Japan,

but also to the overthrow of the shoguns

and the restoration of the imperial family to power.

STEAVU: This re-initiated imperial rule

that has lasted up until nowadays

and brought it, if you will,

back to Emperor Jimmu,

establishing essentially an imperial rule

of over 2,600 years.

NARRATOR: According to some researchers, the remarkable UFO

seen by Commodore Perry's fleet may have been a sign of approval

from otherworldly beings who have been protecting

the imperial family since its foundation.

Ancient aliens established the Japanese imperial family,

ancient aliens protected the Japanese imperial family

and brought Japan into the modern world.

HENRY: This is taken by some

as an affirmation that perhaps

while Commodore Perry is practicing gunboat diplomacy,

maybe so too are the extraterrestrials who had

a hand in the founding of the Imperial Dynasty.

CHILDRESS: When we look at Japan and all of this ancient activity,

the gods coming down, interacting and creating

semi-god, semi-human hybrids and things.

We have these underwater cities there.

We have these special artifacts

that have strange energy associated with them.

All this really seems to add up that,

you know, ancient astronaut theory

is very much validated by the history of Japan.

NARRATOR: From an imperial dynasty that traces its lineage

to the gods,

to a sensational mass UFO sighting

occurring at a critical moment in history...

to new government investigations into unexplained phenomena,

has alien intervention

been taking place in Japan for thousands of years?

Perhaps the mysterious ancient megaliths

that still stand on the island serve as a testament

to an enduring connection with otherworldly beings

who continue to watch over Japan even today.
