Protohistoric narrative

The Japanese have traditionally accepted this sovereign's historical existence, and a mausoleum (misasagi) for Yūryaku is currently maintained. The following information available is taken from the pseudo-historical Kojiki and Nihon Shoki, which are collectively known as or Japanese chronicles. These chronicles include legends and myths, as well as potential historical facts that have since been exaggerated and/or distorted over time. It is recorded in the Kiki that Yūryaku was born to sometime in 417 or 418 AD, and was given the name . As the fifth and youngest son of Emperor Ingyō he was never given the title of "Crown Prince" due to his two older living brothers.

Ascension

Ōhatsuse was thrown into a fit of rage when he learned that his brother Emperor Ankō was assassinated in 456 AD. He then immediately became suspicious of his two elder brothers as conspirers. Ōhatsuse's first action was to question Prince Shirahiko regarding what could have happened. Shirahiko allegedly knew Ōhatsuse was up to no good, so he sat silently which prompted Ōhatsuse to kill him both individually with a sword. He then turned his rage towards the boy assassin (Prince Mayowa), and his other brother Kurohiko by burning him to death. This just left Emperor Richū's eldest son Prince Ichinobe no Oshiwa in contention for the throne.

Ōhatsuse was resentful that Ankō had formally wished to transfer the kingdom to Ichinobe. Both the Nihon Shoki and Kojiki describe how Ōhatsuse took Prince Ichinobe and his younger brother Prince Mima out hunting and "treacherously" killed them. The sons of Prince Ichinobe fled to Harima and went into hiding, later becoming Emperor Kenzō and Emperor Ninken. Ōhatsuse (later known as Emperor Yūryaku) was then enthroned sometime afterwards in November 456. The new emperor subsequently made Asakura no Miya at Sakurai, Nara the ___location of his imperial palace. Emperor Richū's widow Kusaka no Hatabi no hime was appointed Empress with three concubines in March 457.

Reign

According to the Kiki, Emperor Yūryaku's reign was full of tyranny and cruelty. He allegedly ordered a girl to "have her four limbs stretched on a tree and be roasted to death" due to misplaced affection. Another account states that he killed one of his servants during a hunt because his servant did not understand how to cut up animal meat. Yūryaku also allegedly removed a high official to a distant post so he could help himself to the man's wife. The Emperor arbitrary and capriciously killed so many men and women that he was referred to as Emperor of Great Wickedness by the public. However, it is noted that Yūryaku improved his behavior after being admonished by the empress. On a more positive side, Yūryaku greatly encouraged arts and crafts during his reign. Silkworms were cultivated by the Empress, and expert handicraftsmen were commissioned from Baekje (Korea). While the Empress herself never bore Yūryaku any children, he had three sons and two daughters with his concubines.

In the 22nd year of his reign (477 AD) Yūryaku moved the temple of Toyoukeohokami (present: Gaiku temple) from Tamba to Yamada in Ise.

In 463, Yūryaku Tennō invited the thunder god of the Mimuro hill to come to the Imperial Palace, and ordered Chiisakobe no muraji Sugaru to fetch the deity. He obliged, thinking the supernatural being would have no reason to refuse the invitation, and rode carrying a halberd with a red banner, symbolising his office of royal messenger. Soon enough, the thunder struck, and Sugaru enlisted the help of priests to enshrine the kami into a portable carriage, to be brought in the Emperor's presence, as a great serpent. But, said Emperor neglected to practice proper ritual purification and religious abstinence. The thunder kami then showed his displeasure through thundering and threatening fiery eyeballs, and Emperor Yūryaku fled into the interior of the Palace while covering his eyes. The great serpent was returned to Mimuro, and the Emperor made many offerings to appease the angry deity. This story is recorded in Nihongi and mentioned by William George Aston, in "Shinto, the Ancient Religion of Japan" as well as several other books.

Historical assessment

Yūryaku is regarded by historians as a ruler during the 5th century whose existence is generally accepted as fact. Scholar Francis Brinkley lists Emperor Yūryaku under "Protohistoric sovereigns" where he remarks that while some historians have described him as an "austere" man, "few readers of his annals will be disposed to endure such a lenient verdict." Scottish Orientalist scholar and journalist James Murdoch regards Yūryaku as a "much maligned person who was a strong if somewhat ferocious ruler." British academic and author Richard Ponsonby-Fane noted that the Emperor is described as a "mighty hunter" as its recorded that the God "Hitokotonushi" accompanied him in the chase.

A cognitive analysis "as deciphered in the Nihon shoki" was conducted in 2024 by the National Institute of Japanese Literature. In this analysis Emperor Yūryaku was included as an example of "impulsive murder and the tendency to become enraged." Factors such as "the disproportion between the triggering events", "the violence expressed by the emperor on such occasions (quite extreme in degree)", and the "frequent occurrence of such descriptions" were then considered for a conclusion. It is suggested that Emperor Yūryaku may have had an "intermittent explosive disorder, a type of Impulse-control disorder."

The Emperor's interest in poetry is amongst the more well-documented aspects of his character and reign. Poems attributed to him are included in the Man'yōshū, and a number of his verses are preserved in the Kojiki and the Nihonshoki. Archaeological research has also confirmed that large keyhole-shaped tombs belonging to the chiefs of local ruling families disappeared from around the end of the 5th century when Yūryaku reigned.

Outside of the Kiki, the reign of Emperor Kinmei ( – 571 AD) is the first for which contemporary historiography has been able to assign verifiable dates. The conventionally accepted names and dates of the early Emperors were not confirmed as "traditional" though, until the reign of Emperor Kanmu between 737 and 806 AD.

Great King of Yamoto

During this moment in history, the calendar system of the Nihon Shoki changes from before and after Yūryaku's reign. As his name is mentioned at the beginning of the Man'yōshū and Nihon Ryōiki, this is seen as a historical turning point. Previously the Japanese archipelago had been a confederation of powerful ruling families from various regions. This appeared to have changed with the appearance of Emperor Yuryaku as the autocratic rule of the Great King was established and a centralized system centered on the Great King began. This is further supported by a major discovery that occurred in 1968 when the iron Inariyama burial-mound sword was extracted from a tomb. In 1978, X-ray analysis revealed a gold-inlaid inscription that comprises at least 115 Chinese characters. The given year on the sword is denoted as "xin-hai" ("Year of the Metal Pig") according to the Chinese sexagenary cycle, in which the name of the year is recycled every 60 years. While this year is generally regarded in Japan to correspond to 471 AD, at least one historian suggests that 531 is a more likely date.

The person buried in the tomb is given the name "Wowake", who was thought to be an influential warrior in the region. King Waka Takiru in the transcription is thought to be the same person as Ōhatsuse-wakatakeru-no-mikoto as mentioned in the Nihon Shoki, an alias of Emperor Yūryaku. As each inscription contains the name of an official position, this suggests that a system similar to the Bemin was already in place. While the Eta Funayama Sword also apparently mentions the name "Waka Takiru", many characters on that sword are illegible possibly due to polishing by a Japanese sword sharpener at the end of the Taisho period. If Yūryaku's name can be corroborated to this sword then it can be interpreted that the power of the Great King had already extended from Kyushu to Togoku by the latter half of the 5th century.

There is no evidence to suggest that the title tennō (meaning "emperor") was used during the time to which Yūryaku's reign has been assigned. Instead, his title could have possibly been , meaning "the great king who rules all under heaven", or "Great King of Yamato". The name Yūryaku-tennō was more than likely assigned to him posthumously by later generations. His name might have been regularized centuries after the lifetime ascribed to Yūryaku, possibly during the time in which legends about the origins of the imperial dynasty were compiled as the chronicles known today as the Kojiki.

King Bu

There is also a theory that Emperor Yūryaku is synonymous with King Bu (武) as written in the Chinese records. According to the Book of Song, Bu dispatched envoys to Emperor Shun of Song (a Southern Chinese dynasty) in both 477 and 478 AD. The first envoy was to inform the Chinese emperor that King Kō (Emperor Ankō) had died, and his older brother had become king. It is written that he called himself "King of Wa", and the military commander of several different Kingdoms. Its written that in the following year Emperor Shun appointed Bu the title of Grand Peacekeeper-General of the East. The full context of this latter passage describes how Bu's ancestors conquered countries, and expanded their power to the east and west. It describes how they crossed the sea to the north and reached the southern part of the Korean Peninsula. Although the kings of Wa repeatedly requested that the Emperors of the Song dynasty recognize their military control over Baekje, their efforts were denied. The reason for this is thought to be that the Song dynasty placed importance on Baekje, which was located in a strategically important area. By not offering recognition the Song Emperors could put the Northern Wei in check, and avoid opposition from Goguryeo which was in conflict with Wa. Scholar Francis Brinkley notes that the power of the Koma clan (supported by the Liu Song dynasty) in Goguryeo increased steadily during this time. Brinkley suggests that Emperor Yūryaku's attempts to establish close relations with the Chinese Emperor seem to be from a desire to isolate Korea, which ended in failure.

The other two recorded instances regarding King Bu are mentioned in the books of Qi, and Liang. As compared to the former mention in 478 AD, these are not considered to be reliable. Japanese historian Mori Kimiaki points out that both of these appointments coincide with the founding year of their respective dynasties. This is thought to be an administrative matter, and it is not clear whether King Bu (Yūryaku) himself requested it or not. There is at least 1 theory that supports the envoy being sent to Southern Qi in 479 as being factual. This is solely based though, on the description in the title of included in . The fourth and final appointment allegedly made by King Bu (Yūryaku) falls outside of his recorded timeline. As the Kiki states that Emperor Yūryaku died in 479, the last given year of 502 AD would be implausible.

Gravesite

While the actual site of Yūryaku's grave is not known, this regent is traditionally venerated at a memorial Shinto shrine (misasagi) in Habikino, Osaka. As designated by the Imperial Household Agency as Yūryaku's mausoleum, its formal name is Tajihi no Takawashi-no-hara no misasagi. Aside from this shrine in Osaka, there is another burial site named where Yūryaku is a possible burial candidate. Those in doubt of this theory though, point to the construction style of the Kofun which may have begun several decades after Emperor Yūryaku's death. This has led some researchers to add Emperor Ankan as a burial candidate for the Kofun. Yūryaku is also enshrined at the Imperial Palace along with other emperors and members of the Imperial Family at the Three Palace Sanctuaries. He is additionally deified at the in Gose, Nara.
