Emperor Jimmu
Emperor Jimmu was the legendary first emperor of Japan according to the Nihon Shoki and Kojiki. His ascension is traditionally dated as 660 BCE. In Japanese mythology, he was a descendant of the sun goddess Amaterasu, through her grandson Ninigi, as well as a descendant of the storm god Susanoo. He launched a military expedition from Hyūga near the Seto Inland Sea, captured Yamato, and established this as his center of power. In modern Japan, Emperor Jimmu's legendary ascension is marked as National Foundation Day on February 11.
Jimmu is recorded as Japan's first ruler in two early chronicles, Nihon Shoki (721) and Kojiki (712). Nihon Shoki gives the dates of his reign as 660–585 BCE. In the reign of Emperor Kanmu (737–806), the eighth-century scholar Ōmi no Mifune retroactively designated rulers before Emperor Ōjin as tennō (天皇; "heavenly sovereign"), a Japanese pendant to the Chinese imperial title Tiān-dì (天帝), and gave several of them including Jimmu their posthumous names. Prior to this time, these rulers had been known as Sumera no mikoto (皇尊, "divine highness") or Ōkimi (大君, "great lord"). This practice had begun under Empress Suiko, and took root after the Taika Reforms with the ascendancy of the Nakatomi clan. Both the Kojiki and the Nihon Shoki give Jimmu's name as Kamu-yamato Iware-biko no Mikoto (神倭伊波礼琵古命) or Kamu-yamato Iware-biko no Sumeramikoto (神日本磐余彦天皇). Iware indicates a toponym (an old place name in the Nara region) whose precise purport is unclear. '-no-Mikoto' is an honorific, indicating divinity, nobility, or royalty.
In Japanese mythology, the Age of the Gods is the period before Jimmu's accession. The story of Jimmu seems to rework legends associated with the Ōtomo clan (大伴氏), and its function was to establish that clan's links to the ruling family, just as those of Suijin arguably reflect Mononobe tales and the legends in Ōjin's chronicles seem to derive from Soga clan traditions. Jimmu figures as a direct descendant of the sun goddess, Amaterasu via the side of his father, Ugayafukiaezu. Amaterasu had a son called Ame no Oshihomimi no Mikoto and through him a grandson named Ninigi-no-Mikoto. She sent her grandson to the Japanese islands where he eventually married Konohana-Sakuya-hime. Among their three sons was Hikohohodemi no Mikoto, also called Yamasachi-hiko, who married Toyotama-hime. She was the daughter of Ryūjin, the Japanese sea god. They had a single son called Hikonagisa Takeugaya Fukiaezu no Mikoto. The boy was abandoned by his parents at birth and consequently raised by Tamayori-hime, his mother's younger sister. They eventually married and had four sons. The last of these, Hikohohodemi, became Emperor Jimmu.
Migration
According to the chronicles Kojiki and Nihon Shoki, Jimmu's brothers Itsuse no Mikoto, Inahi no Mikoto, and Mikeiri no Mikoto were born in Takachiho, the southern part of Kyūshū in modern-day Miyazaki Prefecture. They moved eastward to find a location more appropriate for administering the entire country. Jimmu's older brother, Itsuse no Mikoto, originally led the migration, and led the clan eastward through the Seto Inland Sea with the assistance of local chieftain Sao Netsuhiko [ja]. As they reached Naniwa (modern-day Osaka), they encountered another local chieftain, Nagasunehiko ("the long-legged man"), and Itsuse was killed in the ensuing battle. Jimmu realized that they had been defeated because they battled eastward against the sun, so he decided to land on the east side of Kii Peninsula and to battle westward. In Japanese legend, during battle with Nagasunehiko a kinki ("golden kite") landed on Jimmu's bow and emitted rays of dazzling light, helping Jimmu defeat his enemies. They reached Kumano, and, with the guidance of a three-legged crow Yatagarasu (八咫烏; lit. 'eight-span crow'), they moved to Yamato. There, they once again battled Nagasunehiko and were victorious. The record in the Nihon Shoki of Emperor Jimmu states that his armed forces defeated a group of Emishi (蝦夷; lit. 'shrimp barbarians') before his enthronement. The Emishi were an ethnic group who lived in Honshu, particularly the Tōhoku region.
Veneration of Jimmu was a central component of the imperial cult that formed following the Meiji Restoration. In 1873, a holiday called Kigensetsu was established on February 11. The holiday commemorated the anniversary of Jimmu's ascension to the throne 2,532 years earlier. After World War II, the holiday was criticized as associated with the "emperor system." too closely It was suspended from 1948 to 1966, but later reinstated as National Foundation Day. Between 1873 and 1945, an imperial envoy sent offerings every year to the supposed site of Jimmu's tomb. In 1890 Kashihara Shrine was established nearby, on the spot where Jimmu was said to have ascended to the throne. Before and during World War II, expansionist propaganda made frequent use of the phrase hakkō ichiu, a term coined by Tanaka Chigaku based on a passage in the Nihon Shoki discussing Emperor Jimmu. Some media incorrectly attributed the phrase to Emperor Jimmu. For the 1940 Kigensetsu celebration, marking the supposed 2,600th anniversary of Jimmu's enthronement, the Peace Tower was constructed in Miyazaki.
Since after World War II, when the prohibition on questioning the Kojiki and the Nihongi was lifted, documentary research in China and archaeological research in Japan has undermined much of the information in both the Kojiki and Nihon Shoki.: 460 No evidence has been found for Jimmu's existence. Today most modern scholars agree that the traditional founding of the imperial dynasty in 660 BCE is a myth and that Jimmu is legendary.: 15 Emperor Sujin's historicity is considered possible by historians, while Emperor Kinmei is the first verifiable historical figure in the imperial lineage. The dates of Jimmu reigning from 660 BCE to 585 BCE are improbable. According to Dr. Lu, the year 660 BCE was probably selected by the writers of Nihon Shoki to put the founding of Japan on a kanoto-tori year. However, the stories of Jimmu may reflect real events of the mid to late Yayoi period. According to historian Peter Wetzler, Jimmu's conquest of Osaka and Nara may reflect an actual event. Still, the dates and many of the details are fictitious. Historian Kenneth G. Henshall stated that Jimmu's conquest may also reflect a time when the Yayoi people from continental Asia immigrated in masses starting from Kyushu and moving eastward during the Yayoi period.
