Japan is home to some of the most intriguing ancient sites in the world. These include burial chambers, sacrificial altars, and stone towers known as “hidden houses” or “nunobas”. The latter are a type of defensive fortifications built by the indigenous Ainu people during the late Jōmon period. These unique, man-made structures are found almost exclusively in Hokkaidō and were used for hunting and as lookout towers to spot potential invaders.

But that’s not all Japan has hiding in its underground. There are so many weird megalithic sites scattered across this country that it would probably be easier to list the ones that don’t have any! From huge cairns to mysterious chambers carved into solid rock, there is no shortage of hidden underground secrets in Japan.

The discovery of strange Ishi-no-Hoden megalith – the ancient mechanism

Not far from the small Japanese city of Takasago, archaeologists were conducting a study of rocks when they noticed a huge stone in an unconventionally regular shape. After examining the object more carefully, the scientists realised that in front of them was a stone block weighing about 600 tons. According to some assumptions, we are talking about a hidden “ancient mechanism”.

The exact date of the discovery is not recorded, but it must have been in the early part of the 19th century. The description given, however, indicates that the megalith was clearly visible even before being discovered by archaeologists and explorers. However, the further study of the megalith is difficult for ethical reasons. A Shinto monastery was built around it. The site is known as Ishi-no-Hoden.

Even with a visual inspection, the Ishi-no-Hoden megalith resembles a giant piece from a more complex technique. A prismatic protrusion was left on one of its planes – it won’t be irrational to imagine that the spike (gear tooth) was intended for implantation into the mechanism.

“The authors of this object had to remove tons of stone from the rock and somehow polish it to an almost mirror shine. At the same time, we did not find a single quarry nearby.” —Dr. Kaoru Tokugawa, Osaka University

On the side surfaces of the megalith there are also grooves, which, according to some theorists, could also serve to move the stone itself along the counterparts in a larger structure. This theory looks more convincing from the prospect of this megalith’s strange shape.

According to many, the surface treatment of the Ishi-no-Hoden megalith does not look like manual work; rather, some kind of mechanical tool was used that could not chip, but grind hard rock. But questions, nevertheless, are rather caused by the purpose of a strange stone, which many indipendent researchers unofficially call the “key”.

There are so many hypotheses and speculations behind this extraordinary rock structure, of which the most fascinating is the “ancient giants”.

Ancient giants and the Japanese megaliths

Giants often appear In the Japanese myths. There are even legends that the heyday of their culture and civilization fell on 40-60 thousand years ago. It is believed that the current Asuka Park was the center, and possibly the capital, of this antediluvian civilization of giants.

It is important to note that official science dated these stones to the 6th or 7th century AD, but detailed studies were not carried out, and the assessment was given on the basis of ancient household artifacts found in this region. Therefore, the stone structures might be much older, and the artifacts found could belong to relatively modern Japanese civilization.

Only on the territory of the park are processed megaliths tens of thousands of years old and weighing from 350 tons to 1500 tons. In fact, such huge blocks are comparable only to Baalbek, where incredibly gigantic blocks with (probably) mechanical processing were also discovered.

To imagine that an ancient master mind decided to cut some unthinkable figure out of a massive whole rock looks like an irrational and stupid exercise. In addition, mainstream scientists claims that Japan is certainly one of the ancient civilizations, but not so much as to be tens of thousands of years old.

In this case, myths come to take its part. Giants are described as good merry fellows, demigods are the descendants of gods and human women. It is noteworthy that such motifs can be found in the myths of many ancient cultures, considering different civilizations and times. As if initially on Earth there were ape-like people along with the descendants of the gods.

A local folklorist named Isura Masazuki claims that Asuka Park contains not just megaliths, but the precise details of ancient stone devices. In principle, such forms really resemble some components of something larger and more complex mechanism. Hence the question of hypothetical giants becomes even more obvious in favor of their reality.

Who built the Giza pyramids? And how exactly they were constructed?

5,000 years ago, the ancient Egyptians may have had a secret way to build the pyramids of Giza. Archaeologists believe that these huge stones were transported from quarries hundreds of miles away and assembled at the site, with help from slaves and primitive T-shaped tools.

The construction of the Giza pyramids is a particularly interesting study in how science, technology and math come together. The pyramids are the only ancient structures known to have used precisely cut blocks weighing up to 80 tons each.

These blocks do not fit together perfectly, but it appears to be some kind of monumental engineering feat. Many wonder if such an undertaking was possible in the absence of modern tools. If so, how was it done?

There are scores of theories on how the pyramids were built, but they all fall short of the reality. And there are even more theories on how they were built using only simple tools like picks and rollers.

It is quite possible that they were built using levers and wheels, but these would not account for the precision required in carving the blocks. They could also have been moved to the site using ramps or sledges, but that would make it much harder for them to fit together perfectly.
Or the stones could be lifted by blocks and ropes.

Building the megaliths of Ishi-no-Hoden and Asuka Park was far more complicated

Though this is intriguing, it is one thing when the Egyptian pyramids were built from relatively small stone blocks, and it is quite another to make something out of parts weighing 1,000 tons, which happened in the many cases of Japanese megaliths.

Apart from this, there is also a presumed tomb in the Asuka Park. Unfortunately, no human remains or household artifacts were found, but the bed itself measures 4.5 meters by 1.8 meters which is clearly not for a human sized body. Some images depicting giant figures are carved in stone on several megaliths. Some even believe that one of these rocks depict a map of the star house of the gods, according to another version, this is information about the life of giants.
