Japan’s Underwater City of the Sea Gods

The gringa’s dear readers may find musings of the lost city of Atlantis as fascinating as the gringa. What if it has actually been discovered off the coast of Japan? Hey, stranger things have happened! Although it is more likely that it is a lost city from Japan’s ancient Jomon civilization, sunk into the ocean thousands of years ago after a cataclysmic earthquake, tsunami or climate upheaval after the last ice age, it is still fun to entertain fantastical theories as well as explore the real science behind this archaeological mystery.

Originally discovered by dive instructor Kihachiro Aratake in 1986, these amazing formations have come to be known as the Yonaguni Monument. This massive underwater complex, dated to have hailed around 8000BC, can be found off the coastline of the island Yonaguni which is part of Japan’s Ryukyu island chain. Extending over an area of almost 1000 feet x 500 feet, the complex consists of ten structures, some appearing to be in the shape of animals as well as to contain glyphs of human characters and animals. Roads and retaining walls can be seen connecting the structure in the pattern of a well designed city.

For decades scuba diving tourists, as well as scuba diving archaeologists, have explored ancient ruins of a castle, majestic archway, five temples, a step pyramid and a massive arena. As the gringa only gets to explore pictures of the ruins, it is still pretty obvious even to my untrained eye that these are man-made. Yet there are still scientists who prefer to believe these are natural formations that were enhanced by ancient people into functional structures. This really aggravates the gringa when scientists wave aside the obvious because they just don’t want to admit that ancient civilizations may have been far more advanced than modern “experts” have traditionally been taught to believe.

Just as the west has Aesop’s fables, Japanese culture has their own popular fables, myths and legends. The Mu civilization is a fabled Pacific people. The ancient tale explains that they disappeared under the waves of the sea. In 1996 Masaaki Kimura, professor of marine geology from Japan’s University of the Ryukyus, began his own research to see if this is the long lost home of the Mu. He, too, was of the belief that Yonaguni was most likely a man-manipulated complex of natural formations. However, he was completely converted after his first dive.

Kimura identified quarry marks on many of the megalithic stones. And, since nature does not normally lay out large stones in symmetrical patterns and create many stones with right angles, the gringa tends to agree with Kimura’s conclusion. He studied carvings that were distinctly human faces and animals. The style was clearly indicative of Asian art. He refers to Egypt’s famous sphinx as he described one underwater sculpture of what seems to be a king. A glyph resembling a horse and a painted relief resembling a cow are still discernible making it apparent that this was not a city of mermaids and mermen living under the sea but was actually a thriving, above-ground metropolis at one time.

This area of the Pacific is famous for earthquakes and tsunamis. In the spring of 1771 the largest tsunami ever recorded struck Yonaguni. With a height of well over 130 feet, a catastrophic oceanic wave such as this would have been powerful enough to blast this ancient city well below the surface of the Pacific. Also, 10,000 years ago the sea level would have been more than 100 feet lower than it is today. The geographical area that the Yonaguni complex sits on would, at the time of its existence, have been well above the sea and on dry ground, a coastal city. A land bridge would have also existed connecting the chain of islands with the mainland making it entirely possible for humans to settle there with their domesticated animals.

Although some experts date the ruins to be about 10,000 years old, Kimura’s estimate gives the complex a much younger age. He suspects it may be a 5,000 year old civilization. Either way, this still places the city’s existence during the time of the Jomon civilization. Evidence to be more specific about the age of the structures is hard to come by. Existing beneath the ocean means that things like pottery or wooden objects have long since decayed and disappeared forever. There is, however, the chance of analysis of the paint used on the cow to get a bit more specific at pinning down a particular century.

Jomon culture during the timeframe considered for these structures can be divided into two separate eras:

  • Incipient Jomon (10,500-8000BC)
  • Initial Jomon (8000-5000BC)

Incipient Jomon civilization has left behind archaeological remains that indicate that the Jomon people were primarily hunter gatherers who produced pottery identified by their pointed bottoms and corded markings.  The following period, Initial Jomon, was noted by rising sea levels and global temperatures. The land bridge between the islands and the mainland would have disappeared. Diet would have transitioned to primarily sea based fare and the development of agriculture and farm production animals since natural resources were limited on the island. Large refuse mounds consisting of large amounts of shells discovered on archeological digs on the islands  attests to this. Remains of stone religious figurines and tools such as knives and axes have also been discovered in island digs and dated to the same period as the underwater city.

Historians describe the culture of the Jomon era to be very complex and in the early stages of organized agricultural develpment. Similarities with Asia’s ancient northeastern cultures as well as the ancient indigenous peoples of the Americas can be detected in many of the artifacts discovered. The Jomon preferred to live in coastal or river communities in homes that were sunken into the earth. Ironic, then, that one of their greatest cities eventually sunk into the ocean.

Although the gringa is unable to scuba dive because of epilepsy, I am certain that at least a few dear readers could join the many tourist divers and send me pictures and a recount of your adventure. During winter months, shark enthusiasts sink beneath the waves to observe the hammerheads that frequent the area.  However, if sharks aren’t your thing, and you prefer the mystery of history, you can always take a detour to the ruins and share your thrills here on the gringa’s blog.

Since the late 90s the underwater city has become increasingly popular among tourists. Famous writers and photographers have braved the waves to record their own bit of history. The Discovery Channel and National Geographic have performed their own expeditions. So, if any dear reader does get the opportunity for a dive of their own, you must drop the gringa a line here and share your own exciting story.

Alien Airports of Nazca

Studying the extra-terrestrial link with ancient Egypt was so much fun the gringa has decided to continue along this same line but head over to the other side of the globe. Did extra-terrestrials have contact with the ancient Incan or pre-Incan civilizations of today’s Peru? Since the gringa’s beloved caveman is from Peru, this subject is especially close to my heart. I’ve always known the caveman’s a bit strange. Perhaps that’s because he’s not from around here. Let’s find out together.

One feature of Peru that is a favorite of ancient alien theorists to point to as supportive evidence of their belief that pre-Incan civilization was in contact with extra-terrestrials is the Nazca lines located south of Lima. For miles elaborate lines etched into the earth stretch across a flattened mountaintop region, covering an area of about sixty square miles. Ufologists describe it as an ancient airport for aircraft. Although there are straight lines that resemble an airstrip, there are also etched into the earth images of animals and geometric patterns. What the heck is all of this for? What were those crazy people doing over a thousand years ago? Who were they? What were their beliefs? What was their culture like?

Most people are familiar with the Incan Empire when the country of Peru is mentioned. However, the Nazca lines were not created by the Incas. The Nazca lines date back to around 500AD, the time period of the coastal cultures of Moche (Mochica) and Nazca. Their cultures are most notable for their warfare characteristics. Moche and Nazca art is filled with images of warriors.

The Moche civilization existed at the right time but they were in the wrong place, too far north. The Moche lived in a region with its southernmost border over 750km (over 450 miles) north of Nazca. Mochica territory stretched from the northern Piura Valley to the southern Huarmey Valley.

That leaves the actual Nazca civilization that had its heyday from 200BC until around 600AD. These folks were in the right place at the right time. Their most important cities were Cahuachi, the religious center, and Ventilla, the center for government, markets and residents. Cahuachi is ground zero for the Nazca lines.

Nazca civilization was known for more than just the famous lines. They also made beautiful pottery and textiles. Nazca was not just one kingdom under one ruler. It was actually a cooperative of chiefdoms who worked together in the interest of their individual groups of people with a Shaman as the spiritual leader. In all, the Nazca population is estimated to have been around 25,000 people.

Since Nazca is located in the coastal desert region of southern Peru, the evidence of wool in their textiles indicates that they engaged in trade with the people further inland of the Cusco region where llama, alpaca and vicuna were raised in the colder, higher altitude climate of the Andes. There is also evidence of trade with rainforest tribes by the presence of feathers from exotic bird species in headdresses discovered in ancient Nazca archaeological sites.

These geographical connections are important because many of the Nazca lines depict images of creatures that did not live in the coastal desert such as the monkey and hummingbird. Contact with civilizations where these animals exist explains why they are featured in Nazcan art. It is also important to note that many of the etchings overlap, some being created earlier and later etchings overlapping them. So, there was no clear, well-thought out “plan” of how all of the images should be arranged. Poor planning if the intent was a high-tech space-port as far as the gringa is concerned.

Polytheistic and pantheistic, The Oculate Being was the principal god of the Nazcas. Mr. Oculate could fly, sported large, googly eyes (the better to be “all-seeing” with), and had Sun-like and serpent-like features and characteristics.



The Nazca lines are geoglyphs etched into the coastal desert floor. They served many purposes, none of which had anything to do with spaceships. Many were connected to sacred ceremonial sites. Others designated the location of an underground water source, which, being a coastal desert, was a critical site. Many were sort of like the labyrinths of Europe. They were designed to be walked as a form of religious meditation or en masse in a formal religious procession. There is also speculation that they could represent a calendar due to astronomical orientation of many of the lines. The images were not created to entertain extra-terrestrials with clever geological art as they approached Nazca for a landing. The images were created to appease the Oculate Being who resided in the sky.

Shamans, rather than priests, were Nazca’s religious leaders. Ceremonies usually involved the Shaman getting high on a psychedelic drink. He would be costumed to impersonate the spirit or deity who would possess him during his psychedelic “trip”. A sampling of a few Nazcan rituals:

  • Using severed head war trophies in human and agricultural fertility rites
  • Music and feasting for harvest celebrations
  • Pilgrimages and marched festivals to bring offerings to the gods at their numerous shrines (shrines were not man-made temples but, rather, certain geographical features or landscapes the Nazcans considered sacred, such as the Pampa de San Jose or the Cerro Blanco mountain)

Religious rituals and festivals centered around agriculture, water and fertility. They built sophisticated aqueduct systems to irrigate their agricultural areas which are still used today. They worshipped nature, the sea, the sky, the earth and water.  Nazcans had shrines dedicated to each deity they worshipped.

With Cahuachi, the religious center, in close proximity to the Nazca lines, the gringa believes the lines are religious expressions. If the purpose of the lines was to be a spaceport for visiting alien dignitaries, it is more likely the lines would have then been closer to Ventilla, Nazca’s urban and government center.

Considering the geology of Peru’s coastal desert, the lines were relatively easy to create. But, as they are actually only visible when airborne were the ancient Nazca people capable of constructing something on such a large scale? Were they advanced mathematicians? How well did they perform where geometry is concerned?

A Canadian archaeologist conducted an exercise to prove that creating these large-scale elaborate geoglyphs is not that difficult. Being a coastal desert, it was easy for ancient Nazcans to get clear sight lines. So, working from a masterful drawing and supervised by a competent mathematician/engineer, teams of Nazcans could accurately recreate a small scale drawing upon the desert floor the size of a football field. To “etch” the line into the earth it was a simple matter of removing the surface materials that were darker due to oxidization and reveal the lighter desert floor underneath. And, judging from the ruins of ancient pyramid structures, Nazca had no shortage of competent mathematicians and engineers.

If you travel in Peru’s coastal desert regions and get off the touristy, beaten path, you’ll be surprised to find that lines are all over the place. Many of them are footpaths. They are not as distinct as the Nazca lines because they are not purposely created as the Nazca lines were. They simply form naturally as the local people tramp from one place to another. Often, walking across the coastal desert is the only way to get from point A to point B.

The caveman and the gringa visited Supe Puerto, a Peruvian coastal desert town. We tramped numerous footpaths as we explored. Below is a screenshot of a lighthouse we trekked to. It was a half day hike from town. The image is at maximum enlargement from Google Earth. However, if you peer closely, you can make out the faint tracing of the footpath hugging the edge of the cliff, following its line with a leg branching off toward the lighthouse. Later, in the middle of the night after our lighthouse adventure, the poor caveman woke up the gringa. He had a nightmare about us falling off the edge of that cliff.

So, the gringa is pretty convinced the caveman is not a descendant of extra-terrestrials. He’s just a regular old Earthling like the gringa. But he is still strange in his own endearing ways.

Comet Fly-By Evidence For 1480BC

In the last installment of the gringa’s examination of “evidence” used by ufologists and ancient alien theorists to assert that ancient Egypt had extra-terrestrial contact or were extra-terrestrial hybrids, I explored the theories and ideas associated with the Tulli papyrus. Rather than perceive the dubious document as an ancient Egyptian record of a sighting of mass UFO visitation, the gringa interpreted the astronomical event to be a near fly-by of a comet cluster. So, the obvious next question is, “Were there any comets in Earth’s vicinity around the time of 1480BC or thereabouts?”

Even though expert translators dated the Tulli papyrus to 1480BC there is definitely room for error where that date is concerned. They could not definitively attribute it to the reign of Thutmosis III. They also did not have access to the alleged original papyrus to conduct Carbon 14 dating or any other diagnotic tests to determine its age. So, the gringa goes with the “1480BC or thereabouts” timeline.

When the gringa allows a bit of fluidity in the timeline, things do, indeed, get interesting. There seems to be astronomical and historical records to support a comet cluster or massive comet with a large tail. Author Graham Phillips asserts in his book, “The End of Eden”, that an extraordinary comet event occurred which the civilizations of Earth reacted to with awe and fear in 1486BC.

Confirming the 1486BC comet event are Chinese court records of observation of a comet with ten tails during this same time period. The Chinese record is preserved on a swath of silk, the Mawangdui Silk Almanac, and is preserved in Changsha, China at the Hunan Provincial Museum. This court record was discovered in the 1970s in a tomb and was part of an almanac of astronomical records. The almanac was dated to about 300BC and included an entry for the ten tailed comet of 1486BC.

The significance of this event is that it changed religious history in China as well as Egypt and could very well have been the catalyst for years of war and conquest that ensued throughout Asia, India and Egypt after it appeared. Monotheism worshipping a single great god began to be practiced in China and Egypt. Ancient glyphs depicting what appears to be the same comet appear in China and Egypt:

chinese lao tien yeh glyp

Chinese Lao-Tien-Yeh glyph

glyph of aten

Egyptian glyph of Aten

Considering that the Tulli papyrus recorded that the event was smelly and rained down fish and “volatiles” (the gringa supposes this would mean objects that were considered to have been burned, were on fire, hot or smelled sulphurous), if it was a comet fly-by, this would have been caused by tail debris breaking loose and passing through Earth’s atmosphere and raining down upon Egypt with large pieces impacting the rivers thus throwing up fish. Are there comets capable of this?

From 467BC-466BC ancient Greek celestial records report that a comet, possibly Halley’s comet, passed Earth. The Greek records indicate that a great meteorite impacted the northern region of Greece. Could this have really occurred? Does Halley’s Comet get close enough to Earth for tail debris to possibly be affected by Earth’s gravity, break away, enter the atmosphere, and, ultimately, if it doesn’t burn up during entry, impact the Earth?

In 1910 the New York Times reported that the tail of Halley’s Comet (it is 24 million miles long) would be traveling through Earth’s atmosphere for a duration of about six hours. It seems entirely possible that any large comet that passes near enough Earth to be seen with the naked eye, with a tail long enough that debris in the tail could enter Earth’s atmosphere, might have tail debris that could be affected by Earth’s gravity, break away and fall to Earth.

Halley's Comet.philosophyofscienceportal.blogspot

Interestingly enough Halley’s Comet has a predictable cycle and elaborate tail. It visits Earth about every 75 years. It’s earliest confirmed arrival is in Chinese astronomical records of 240BC. It is entirely possible this was the comet seen in China and Egypt 1240 years earlier in 1486BC. But there are also other comets that could have been seen:


The “Great Comet of 1744”, also known as de Cheseaux’s comet, was a magnificent 7-tailed comet observed from November, 1743 until April, 1744. During these months it shone with such brightness it was visible to the naked eye. It was rated as being the sixth brightest classification for a comet. This means that even during the day it was as bright as the Sirius star at night.

It was observed all over the world with astronomical records of the United States, France, Russia and Japan among the many nations who have official records of the comet’s sighting. Japanese records even indicate that their astronomers detected audible noises and an aurora as tail particles interacted with Earth’s magnetosphere.


The Great Comet of 1680 was visible from November, 1680 until February, 1681. Astronomers all over the world recorded this event and artists immortalized it. Official astronomical records can be found in Germany and the United States.


The Great Comet of 1882, also called the Great Comet of 1881, or the Great September Comet of 1882, or Super Comet, may very well be the brightest comet ever observed by Earthlings. Italian sailors first reported it to authorities in September, 1882. It grew brighter as it traveled toward the Sun. Astronomical records from Spain called it a blazing star. Eventually it broke into four sections and could be observed for weeks as a bright heavenly object with a luminous tail.

With all of this data on comets and historical records confirming observances in China during the same event recorded on the Tulli papyrus, the gringa’s belief that the Tulli papyrus recorded a comet event is now stronger than ever.
