On November 27, 2018, it was announced that a building derived from a migrant called "Large Wall Building" built from the end of the 4th century to the beginning of the 5th century was found at the Ichio Kande site in Nara prefecture.
Speaking of the end of the 4th century to the 5th century, Japan is "blank 4th century " The era when it is said.
It was thought that the migrants migrated after Emperor Yuryaku (reigned in the latter half of the 5th century), one of the five kings of Wa, so the settlement time may be significantly earlier. ..
With that said, there was a discovery that seemed to throw a stone in the elucidation of the mystery of the blank 4th century, so I would like to delve into the "blank 4th century".
Changes in Japan after the blank 4th century
It is a Chinese history book that can be a clue to know ancient Japan, but Iyo in the middle of the 3rd century. From the description of the tribute to the tribute by his 413 Kings of Wa "San", " Wa ] Will be lost.
How archaeologically valuable in Japan Forbidden [ sanctuary ] where excavations are never allowed, no matter where they are ] Is the tomb of Emperor Nintoku and others [ Tumulus ] So, the place where the secret of the Emperor is touched is that, so I do not know the details of what happened in Japan around the 4th century.
Therefore, the appearance of ancient Japan in the present official history is a mixture of myths and legends, and it continues to be left unclear.
Significant changes were seen during this blank period:[ Tomb ], It changed from a tomb that was only a hill to a complex shape such as a keyhole-shaped tumulus, and was a representative of ritual tools in the Yayoi period [ Dotaku . ] Discontinued, [ Bronze ] Was the main metal object [ ironware ] Will be used.
In addition, the body shape that was closer to the Jomon people with deeper carvings changed to a continental body shape with shallow carvings, and for some reason, it was done until then [ tattoos ] Habit disappears.
In the latter half of the 4th century, historical changes became remarkable, and the tombs exceeded 100 m [ keyhole-shaped tumuli . ] Is the center, and [ mural ] Will be drawn. While grave goods were mainly swords, mirrors, and balls, they will incorporate the culture of the Korean Peninsula and continents such as harnesses and crowns.
There were no horses or cows in Yamatai! ??
Chinese historical materials from the Himiko era [ Wajinden ], [ There are no horses or cows in the countries of Wa, let alone Yamatai ], But when Yamatai Kuni disappeared at the end of the 3rd century, [harness] and [burial horse bone] Is said to have been excavated in large quantities.
The circumstantial evidence clearly shows that the horse came from the continent, but it is hard to think that the horse came by itself, so it is speculated that there was an existence that brought the horse for some reason. increase.
So,
- How many horses and people came from the Korean Peninsula?
- Did a small group of horses arrive in stages?
- Did a huge group of horsemen come to attack with a large army?
The question arises.
If the details of this period are recorded, the influx of horses and migrants will be known, but only from the end of the 3rd century to the beginning of the 5th century, Chinese historical materials do not mention Wakoku. is.
The era of the Japanese archipelago around the 4th century, when the big historical events of the disappearance of Yamatai and the birth of the Yamato administration took place, has reached the present without knowing the actual situation, and there are various theories including the controversy over the location of Yamatai. Flying [ Mysterious 4th Century ] And [ Blank 4th Century ] Is called.
There have been major changes, but above all, the fact that weapons and harnesses have been found can be inferred to have caused a great deal of conflict around the time. * It's just an amateur idea
Looking at the wording on the Gwanggaeto monument, it may be the influence of the foreign war with Goguryeo.
Gwanggaeto Monument – Quoted from Wikipedia
Although it is the view of the Japanese side, there is a description that Wakoku crossed the sea in the battle with Goguryeo. Considering that "I crossed the sea and attacked another country", it seems that Japan was organized to some extent at this point.
Why did weapons and harnesses come to Japan?
So why did we find so many weapons and harnesses that we hadn't seen before (the Chinese history book said that there were no horses in Wakoku during the Yamatai era)?
If we needed weapons and horses to bring the country together in a domestic battle, we would probably have an advantage. However, weapons did not inhabit horses anyway, so foreign help is indispensable to prepare horses.
In fact, there was an article telling a story that seemed to be the answer.
It was around the 3rd century, going back from that time. It is said that cooling was occurring in the northern part of the Eurasian continent. As a result, ethnic movements became more active in search of food (which even affected the Roman Empire), and the Chinese Empire also entered an era of turmoil (Japan also entered the "Wakoku War" after the death of Himiko).
Goguryeo has also started moving south in response to the movement.
* Since it is a map of the 3rd century, it is the original Samhan era. Later, it changed to a nation of Mahan → Baekje, Byeonhan → Gaya, Jinhan → Silla.
It seems that Goguryeo was a powerful cavalry corps (Mongolia is also close, and I can imagine that there are a lot of horses somehow).
The action taken there
- Baekje / Gaya → Ask Wakoku for cooperation
- Silla → He went down to Goguryeo.
You can't just know a horse when dealing with a cavalry corps. For that reason, did you bring horses, harnesses, and weapons to Wakoku? And, he introduces such a theory.
This time, the fact that the settlement of the migrants has been revealed may reveal the events before and after the establishment of the Yamato administration.
