It's about the same ethnicity as Korea and Japan. 4

 It is proved in many ways that Emperor Oh Jin and Chiljido, the first Baekje rulers, ran the Japanese Empire in earnest from the Kawachi Dynasty of the shipwreck. Here, let's take a closer look at Emperor Nintoku, who pioneered the Baekje army of the shipwreck, and Emperor Oujin, his father and the first Baekje ruler in Japan, around the 4th century. First of all, proving that Emperor Oujin was the Huwang of his motherland Baekje appears in Chiljido Island, the beginning of the historical world of Korea and Japan. In the period of Emperor Oujin of the Japanese book "Gosagi" (712 Compilation), "King Geunchogo of Baekje dedicated a mare and a male horse through Mr. Still Ki." In addition, it is recorded that a large mirror and a horizontal road were dedicated." In addition, the Japanese Clerk (720 compilation) states that in the 52nd year of Empress Jinguuu, "a bag of Chiljido, a piece of Chiljagyeong, and various valuable treasures were offered." In this way, Japanese historians are nodding their heads that the article of Tuui, saying that the Baekje king "gosagi" and "Japanese secretary" were written when the "gosagi" and "Japanese secretary" were manipulated in the future. This is what Japanese scholar Suzumu Oono's research paper says in 1919. "Gosagi" says that King Geunchogo of Baekje still dedicated a horizontal and large mirror to the Japanese king through Mr. Gi. In the Japanese Clerk, it is said that King Geunchogo dedicated Chiljido and Chiljagyeong. This article is written where it is estimated to be 367 AD. However, if you look at it now, there is Chiljido in Isonokami Shrine in Yamato, and this knife has the part "Honsang in the 4th year of Taehwa (369)." Since Ji is a letter similar to Ji in the past, it is thought that Hoenggo in Gosagi, Chiljido in Japanese Seogi, and Chiljido in Isonokami Shrine refer to the same knife. For this reason, it can be said that Mr. Still Ki came to the royal family with this knife in 369. According to the Japanese Clerk, Mr. Still Ki was fluent in scriptures and became the teacher of the crown prince. The arrival and settlement of these people is centered around 369 AD, as can be seen from the letters engraved on Chiljido Island, which is called the 4th year of Taehwa." I generally agree with Professor Oono's argument as described above. However, in his essay, it can be said that the passage "Cheonsang" of Chiljido Island sent by King Baekje to the Japanese king overturns the inscription engraved on this knife 180 degrees. Whether it is a tribute or a sergeant, let's take a look at the Chinese characters engraved on the front and back of Chiljido Island manufactured in Baekje 1630 years ago. The Chinese character inscription on the front of the knife is as follows.  The inscription engraved on the back of the knife "泰四十十丙丙陽陽 ' ' ' ' ' ' '作作作作□□□□" is as follows. '先世以來夫有此刀 百滋王世子奇生聖音 故爲倭王旨造 傳示後世' 

The above Chinese inscription is a multi-faceted reading of the letters of rusty Chiljido by Japanese scholars. If I translate this Chinese inscription, it is as follows. (The front) "In 369 AD (the 4th year of Taehwa), I made this Chiljido map with steel that has been cut countless times in broad daylight on May 16th of the lunar calendar. This sword is sent to Huwang so that all enemy soldiers can be defeated." (Backside) "This sword, which was not yet seen after the ancestors, is made for the Japanese king as a holy word, so make it visible to future generations." Like this, Baekje King Geuncho and Gwisuja made a great map of the unknown Kingdom. With that knife, the Japanese king defeated all enemies and declared that they would thrive by striving to preserve the Baekje colony. No matter who reads this inscription of Chiljido, it can be seen that it is a descending text delivered by the upper person to the lower person. In other words, it is a report sent by King Geunchogo and Crown Prince Gwisu of Baekje, the late King Geungusu, 375-384 blessed Emperor Oujin of Japan and his future generation. In fact, it has already been proven that Japan was the home of Baekje, which was owned by Baekje's Huwang. In other words, the inscription of Chiljido Island is a decisive archaeological evidence proving that Baekje managed Japan as the Baekje Kingdom in ancient history of Korea and Japan. Nevertheless, some Japanese historians make wrong claims, such as offering a tribute theory that they paid the sergeant's theory to overturn it, so we have no choice but to examine their opinions. This is what is written in the Chiljido section of "Japanese History Dictionary," "本竹竹竹竹, 1976." "It comes from the shrine of Isonokami Shrine in Tenri, Nara." This Chiljido (지고지고)) is believed to correspond to Chiljido (枝刀)) shown in the 52nd year article of Empress Shingong in "Japanese Clerk." The total length is about 75cm. It looks like a double-edged branch knife, which is three each on the left and right sides of the knife body, and is not a practical knife. On both sides of the sword body, there are about 60 prestigious texts inlaid with gold. This Chiljido map was interpreted in depth in relation to the interests of East Asian countries at that time, but there is no established theory yet. It is understood that Baekje King made it for the Japanese king in 369 AD, and there is a theory that Baekje King granted it to the Japanese king, and Dongjin gave it to the Japanese king through the Baekje king. National treasure." First, let's take a look at Professor Masaki Ueda of Kyoto University (1927~). Ueda is a scholar who visited the Isonokami Shrine three times to study and review Chiljido Island and examined the inscriptions of the front and back of the knife while touching it. Ueda reveals in detail that King Baekje gave it to the king of Japan in detail in his book, 1976. Some of the 60 letters engraved on Chiljido Island are difficult to read, so the full text cannot be read perfectly. According to what has been discovered after much consideration so far, it would be nice to say that nowhere in Carl's prestigious text can prove that King Baekje dedicated to the Japanese king. Nevertheless, the "constitutional theory" has been argued so far without much doubt under the guise of an article of 52 years of Empress Shin Gong of the problematic "Japanese Clerk." The prestigious interpretation must first be based on the prestigious itself. Although the "Japanese Clerk" is a valuable classic, it is absurd to decode the inscription of Chiljido based on the "Japanese Clerk" completed from the late 7th century to the early 8th century. In the prestigious text of Chiljido, it is said that King Baekje made it for the king of Japan, and that this knife is well conveyed to future generations, and the subject who made this knife is also the king of Baekje. In addition, it is a loophole in the theory of trying to see Dongjin as the main subject of Chiljido Island that no single sword that looks like Chiljido Island was found in China. On the other hand, Korea has iron similar to Chiljido. What I actually saw was a 24cm long iron excavated from Hwangsang-dong No. 1 tomb in Indong-myeon, Chilgok-gun, Gyeongsangbuk-do in 1962, and a 21cm and 14.3cm long iron excavated from the remains of Oryundae, Dongnae-gu, Busan in 1971. Like Chiljido, these also have three branches on both left and right sides of the knife. Such a thing was also excavated from the ancient tombs in Sangbaek-ri, Hamyang, Gyeongsangnam-do, and it is called a ritual. At that time, the Baekje forces showed a stronger national power. It is impossible to say that King Baekje, who was in such a position, dedicated Chiljido Island by subjugating the king of Japan. Moreover, even in the prestigious itself, there is no text to confirm that King Baekje dedicated Chiljido to the king of Japan. It must have been an attempt to strengthen the military alliance that King Baekje created the initiative of Byeoksa, which is said to be able to "defeat all military forces," and handed them over to the Japanese king. If you look at the Oujin Cheonhwangjo in Gosagi, it is written that King Geunchogo of Baekje dedicated Hoenggo and a large mirror. However, Hoengdo and large mirrors are used as Chiljido and Chiljagyeong in "Japanese Seogi." Perhaps because the "Japanese Clerk" compilers knew in advance that Chiljido was actually enshrined in the Isonokami Shrine, Professor Masaki Ueda deliberately wrote an article on Chiljido." As such, Professor Masaki Ueda is objectively proving Chiljido. As Ueda pointed out in the fabricated history book "Japanese Clerk," "Japanese Clerk" is also a very notorious history book because it contains many false articles. It must be investigated when and how articles different from the facts in the "Japanese Clerk" were written. It has yet to be revealed in Japanese historical circles whether a false article was published from the time the "Japanese Clerk" and "Kosagi" were compiled in the early 8th century, or whether it was manipulated in the transcription process of copying the original articles with brushes. Until now, literature criticism has continued that the article has been manipulated, and only a few facts have been confirmed that it is the "Shingong Empress's invasion of Silla" and that the so-called "Im Nail Headquarters" in Gaya is a manipulated record. As I examine, false articles such as "Japanese Clerk" were manipulated during the reign of Toyotomi Hideyoshi (1536-1598), who caused the Japanese Invasion of Korea in 1592. This is because the prestige of the invasion of Joseon would not have stood without overturning the facts that the Japanese Empire had been ruled by the Baekje Kingdom in Japanese historical records.

Therefore, if the Baekje king says Chiljido, which was given to the later king, the Japanese king, in the letters of Chiljido, or Heonsang, absurdly manipulated it, and introduced the theory of invasion of Silla by Empress Shingong and Imna Ilbonseol, it would not exist. In particular, Professor Kojiro Naoki ()孝郞, 1919~) refutes the records of manipulation of Japanese kings, which do not exist, one by one in his book (本本話代代 199 199 199, 1990). "In order to make the origin of the emperor as old as possible, the name of the emperor, which had never existed, was manipulated and added. In addition, based on the theory of Chamwi, Queen Suiko's 9th year (601) to 1260 years ago (660 BC) was made the year of Emperor Jinmu's throne. The story of the first Emperor Jinmu was also fabricated to establish authority while explaining the origin of the Emperor's family, and cannot be seen as a fact." As such, modern Japanese historians have continued to argue and criticize the manipulation and alteration of historical books such as "Japanese Clerk." Let's go back to the question of Japanese militarism. Tomonobu Kurihara claims that Chiljido Island was made in Dongjin, the land of China, and granted to the Japanese king through King Baekje. He makes such an argument by calling the letter "Seong-eum" in the inscription on the back of Chiljido Island "Seong-jin." In summary, in order to reward the Japanese king for helping Baekje's difficult circumstances, Haesogong, the emperor of Dongjin, the birthplace of Baekje, produced a Chiljido map and donated it to the Japanese king through Baekje. However, in view of the context of the Chiljido inscription, if the "Seonggeum" is decoded as "Seongjin," the sentence cannot be established at all. Second, in the postwar period when Baekje made Chiljido Island and gave it to the Japanese king, Baekje was in full swing of very strong national power on the Korean Peninsula, rather than in a "difficult situation." Masaki Ueda, who wrote earlier, also pointed out this point. Even if you look at the History of the Three Kingdoms, a historical book of Korea, Baekje fought violently against Goguryeo, which was moving south in the 4th year of Taehwa (369 AD), and rather advanced northward. In addition, in 371, Baekje troops invaded Pyongyang, the Goguryeo Kingdom, and because of that, Goguryeo's King Gogukwon (reigned in 331-371) was killed. Therefore, Tomonobu Kurihara's theory of dongjin cannot escape criticism that it is absurd. Chiljido Island was discovered in the Isonokami Shrine from 1873 to 1874. It was Masatomo Suga (1824-1897) who found this knife. It was in 1873 that Suga, a historian, became Gungsa, the manager of the Isonokami Shrine, and it is said that after taking the position of Gungsa, it was found in Chiljido Island. He did not reveal the exact date of seeing Chiljido Island for the first time, but when he took out this Chiljido Island in the early days of his appointment to the shrine, he said that he had rust on his knife, and that inlaid with gold appeared on his body. However, it was on July 15, 1875 that a rubbing copy of this painting of Chiljido (a book that folds and unfolds the ground) was released. At that time, Shikitane Ninakawa published this script to the world, and when the script was announced, it immediately became a hot topic in Japan. This is because the inscription that the ancient Baekje King gave Chiljido Island while having the Japanese king as Huwang was recorded in the script. I think it was the Japanese militarists who were very embarrassed. This is because Takamori Saigo (1822-1877), Japan's Saigo, and others were openly planning an invasion of Joseon from around 1871 with the theory of Jeonghan. In addition, on November 28, 1872, Emperor Meiji's "Jingbyeonggoyu" was published. "…Navy and Army shall be established by supplementing the military system since ancient times, and all citizens of the country should be incorporated into the military register if they reach the age of 20..."' This was the birthplace of Japanese militarism. Eventually, in September 1875, the Japanese warship Unyo invaded the West Sea and caused the Ganghwado incident. In 1876, the following year, the Japanese military forced the Joseon government to protest by sending six warships and 400 soldiers to Ganghwado Island instead of Kiyotaka Kuroda (1840-1900), and eventually signed the Treaty of Protection between Korea and Japan. In this way, during the period when Japan's invasion of Joseon was blatant, Chiljido Wetland was published, so wouldn't Japanese militarists have tried to do something? If you look at the inscription of the four-letter Chiljido, which is missing from Chiljido Island, four letters at the end of the prestigious map are carved. In other words, it is in □□□□ order. Who cut these four letters off? Professor Masaki Ueda pointed out that the four letters were intentionally cut off by someone. About 60 letters are engraved on the front and back of the Chiljido sword body in gold. What's a waste is that the point of about a third of the lower part of the knife is broken, and there are not a few parts where the inscription has been cut off, and there are even places that are thought to have been intentionally cut."(支 197 197支 197 197 197, 1973). It was said earlier that it was Masatomo Suga who found this knife for the first time in the Isonokami Shrine, removed the rust and informed the world of the inscription that became a gold inlaid. So, he didn't just remove the rust of Chiljido Island, but also cut off four letters? However, he said that the front and back of Chilji were blackened, so he removed all the rust and found prestigious letters in gold, so it cannot be concluded that he cut off four letters while removing the rust. However, if you look at his actions, something strange stands out. In 1877, he left the palace position of Isonokami Shrine and moved to the Pyeonsaguk of Taejeonggwan, the cabinet of Japanese militarism, and in 1888, he became a Pyeonsaguk Pyeonsaguk of Tokyo University. He wrote a paper called Imnago (1893) while working in a polarizing country, and he presented a tribute article by the Japanese Clerk that King Baekje gave Chiljido to the Japanese king, and emphasized the so-called Imnajonbonseol, a false article by the Japanese Clerk. The time when he published his thesis called Im Nago (1893) was just before 250,000 Japanese troops had already entered the Joseon Peninsula and soon pushed into the Qing Dynasty. He, who was in charge of revealing the truth of history, may have suffered from the pressure of Japanese warlords. However, even if Imnago is regarded as being used to lay the historical basis for Japan's invasion of Joseon, when and by whom did the four letters in front of Chiljido, the treasure of King Baekje, were cut off? Was it when Masatomo Suga was in charge of the Isonokami Shrine (1873-1877), or was it after that? I speculate that it may have been after March 16, 1885, when Yukichi Fukuzawa's Tala Theory, which specifically reinforced the "Jeonghan Theory" as Japanese militarism expanded day by day. In addition, it may have been militarists who committed this. The name of the Baekje Kingdom or Baekje Dogum maker would have been engraved on the Nukja, which was carved out of the pen. This is because it is engraved in the inscription that King Baekje and Crown Prince are giving gifts to King Wa Dae, the latter king. It is estimated in 402 AD that Emperor Oujin, who was granted Chiljido Island by Emperor Nintoku and King Geunchogo of Dr. Wangin, died. And it is considered in AD 405 that his fourth prince, Oosajagi Nomikoto, succeeded Emperor Oujino and Kiiratsuko (third prince) at the earnest recommendation of his prince. The historical facts of this time are recorded in detail in "Kokinshu," compiled by the Baekje scholar, Kinosurayuki, 872-945 in 905. "It was when Oosajagi Nomikoto was a prince. Three years have passed without ascension because he gave up the position of the third prince and Donggung Palace to each other. At this time, Wangin wrote and recited the rest of the songs he felt sorry for. …The song, which recommended Ohsajagi Nomikoto to ascend to the throne, said, "This flower blooms in the shipwreck. This flower sleeps in winter and now blooms in spring." In this way, Dr. Wang In, who crossed from Baekje during the reign of Emperor Oujin and became a teacher of princes, took the lead in ascending the fourth prince to the throne, which had been empty for three years. This is a part that allows the royal family to fully reflect on the prestige they enjoyed in the royal family. Wangin also named today's Osaka Port as Nanpajin, the name of the time, as can be seen in this poem, and named Waka, the first poem of the ancient Japanese Dynasty. The beginning of the poem Wakara, which Japan boasts today, was none other than Wangin's poem "Wanpajinga" (월'現現 1997 1997, February 1997). Interestingly, however, there were no texts on Japanese land at the time when Wangin built Waka for the first time in the Japanese country. At that time, Wangin wrote a poem using Chinese characters as a borrowed language, just like Hyangchal used on the Korean Peninsula. In this way, it is called "Manyoukana" to describe the native's Japanese language in Chinese characters. This is a Chinese character notation for ancient Japanese, such as the combination of biceps and hyangchal during the Three Kingdoms Period of Korea. A bronze mirror proving that the Japanese Empire was the Baekje Kingdom was also found in the tomb of Emperor Nintendo, a secret of the Royal Tomb of Nintendo, drawing attention from academia. It is "Sudaegyeong," which is currently displayed at the Boston Museum of Art in the United States. This 23.5cm diameter Su Dae-gyeong was registered as a collection of the Boston Museum in the United States in 1908, and it is known that in 1872, the royal tomb in Osaka, Japan, was excavated when part of the royal tomb was destroyed by a landslide. Mitsusata Inoue (1917~), a professor at the University of Tokyo, pointed out the following about the bronze mirror of the "Sudaegyeong" of King Innotoku's tomb.

"The Boston Museum of Art in the United States displays excellent artifacts that are said to have been excavated from Nintendo Kureung. One is "Sudaegyeong" in the latter part of the Han Dynasty, and the other is "Hwandubyeong," a luxurious sword-handled sword made a lot in Namseon (South Korea). These two artifacts were already in the collection of the Boston Museum of Art in 1908 (41 41 41), and are also recorded in the museum list. These relics may have been leaked to foreign countries from the stone crown in front of the Nintokurung Tomb." This story may be surprisingly heard by the general public. However, ancient tombs are a common phenomenon throughout the East and West. Even the heavenly tomb, which is so divine that even experts do not allow access today, has actually been robbed in the past. During the Heian period (794-1192), an incident occurred in which the Royal Tomb of Seimucheon was robbed, and 16 people, including a Buddhist monk Koufukuji, were killed. In any case, Mitsusata Inoue suggests that the "Sudaegyeong" of the Boston Museum of Art is a thief excavated from the tomb of King Nintendo in Japan. He also points out that the mirror was made in ancient China. However, Inoue's opinion seems to have quoted the Japanese version of the book, "대スト術術洋洋洋洋 S S," and the explanation of "Sudaegyeong" recorded in SELECTED MASTERPIECES OF ASIAN ART 1890-1990 Museum of Fine Arts, Boston) published by the Boston Museum. This is because the book has a speculative explanation that "it is thought to have been made in a generous era" for "Sudaegyeong." However, the people involved in editing this book were Japanese. The Boston Museum had four Japanese employees, including Kojiro Tomita (1890-1976), the head of the East Department, who had worked for 55 years. It seems that some of them wrote an explanation and speculated the "Sudaegyeong" bronze mirror as that of ancient China. However, the National Gongju Museum (Director Kim Jong-man, Kim Young-won) discovered that the bronze mirror "Chair Sonsu Dae-gyeong" excavated from the tomb of King Muryeong of Baekje in 1971 not only has the same diameter as the Boston Museum of Art's "Sudaegyeong" but also has the same pattern of beasts cast in the mirror. In the case of the relief of the painting of the envoy of "Sudaegyeong of Chair Son," the relief of the painting of Jujak, Cheongryong, and Baekho are exactly the same when overlapped with the relief of the painting of "Sudaegyeong." However, the painting of Hyeonmu in "Chair Sonsu Daegyeong" is so corroded that it is hard to see. However, in addition to the relief of the envoy, these two bronze mirrors are placed in a thin line between the four-leaf jwaryu, which is a three-legged bird, Samjoko, and seven toad-like protrusions, forming the inner rim. Therefore, it is believed that the Baekje bronze mirror engraved with seven four-leaf left oil was the Chiljagyeong, which is said to have been sent to the Japanese king from Baekje. According to the "Japanese Clerk" (52nd year of the reign), it is revealed that the Baekje envoy Gujeo and others sent a pack of Chiljido, Chiljagyeong, and various kinds of Jungbo to the king of Japan. In addition, "Gosagi" records that King Geunchogo of Baekje brought two male and female horses, Hoenggo, and a large mirror to Mr. Still Ki. Japanese scholars admit that these two records are common. Japanese scholars are also admitting that "Sudaegyeong" in the Boston Museum of Art and "Sudaegyeong" in the tomb of King Muryeong look very similar to each other. Professor Mori Koichi of Toshisha University is known to have studied the two mirrors (hand-screw and chair-hand-screw). Mori said, "In China, we didn't make this kind of mirror. It is because such mirrors have never been excavated from China (KBS TV interview, aired on May 15, 1999). However, he raises the possibility of Su Dae-kyung's production in Japan, saying that it should be determined whether the place where these two mirrors were copied and produced is Baekje or Japan. If the Su Dae-kyung in question is the Chilja-gyeong delivered by the "Japanese Clerk," it is clearly sent by Baekje and is subject to discussion. However, if "Sudaegyeong" is simply an excavation of the royal tomb of Nintokucheon Stream, the hypothesis that the bronze mirror was made in Japan may be discussed. Unfortunately, however, Mori's Japanese production hypothesis seems to be impossible to establish. This is because there is no evidence or report that any bronze mirror was made in Japan in the 5th century during the reign of Emperor Nintendo. In addition, the nationality of other burial items (Hwandubyeong, Samhwanryeong, etc.) that were excavated in 1872 due to landslides in the Royal Tomb of Nintendo Cucheon along with Sudaegyeong proved that they were all made on the ancient Korean Peninsula. For example, in the case of Hwandubyeong, a large sword handle, almost the same thing was excavated from the tomb of King Muryeong in 1971, and in the case of Samhwanryeong, the same things were excavated from Silla tombs. Then, what is the reason why "Sudaegyeong," whose original name is "Chiljagyeong (big mirror)," was excavated from the Nintoku Heavenly Tomb in Kawachi, Osaka? Emperor Nintoku was the fourth prince of Emperor Oujin and succeeded Emperor Oujin, so it is presumed to have been passed down from the vice king of Chiljagyeongdo. Now, let's draw the conclusion of this article. Chiljido, which was handed down from Baekje during the reign of Emperor Oujin, a bronze mirror excavated from the tomb of Emperor Nintoku, the son of Emperor Oujin, and a portrait of Emperor Keikai, the younger brother of King Muryeong, are all very valuable evidence.
