was the 29th emperor of Japan, according to the traditional order of succession. His reign is said to have spanned the years from 539 to 571. Most historians support either the view that Kinmei is the first historically verifiable Japanese emperor or the view that Yuryaku (the 21st) is.
Kinmei's contemporary title would not have been tennà Â, as most historians believe this title was not introduced until the reigns of Emperor Tenmu and Empress Jità Â. Rather, it was presumably , meaning "the great king who rules all under heaven". Alternatively, Kinmei might have been referred to as or the "Great King of Yamato".
Because of several chronological discrepancies in the account of Emperor Kinmei in the Nihon Shoki, some believe that he was actually ruling a rival court to that of Emperors Ankan and Senka. Nevertheless, according to the traditional account, it was not until the death of Emperor Kinmei's older brother Emperor Senka that he gained the throne.
Before he came to the throne (at least according to the Nihon Shoki) he was hesitant and refused to wield power stating:
The Empress, Kasuga no Yamada, refused this believing Kinmei was compassionate and smart enough to rule. However, historians such as William George Aston have questioned this with Aston himself noting that:
According to this account, Emperor Senka died in 539 at the age of 73; and succession passed to the third son of Emperor Keitai. This Imperial Prince was the next youngest brother of Emperor Senka. He would come to be known as Emperor Kinmei. He established his court at in Yamato.
The Emperor's chief counselors were:
Although the imperial court was not moved to the Asuka region of Japan until 592, Emperor Kinmei's rule is considered by some to be the beginning of the Asuka period of Yamato Japan, particularly by those who associate the Asuka period primarily with the introduction of Buddhism to Japan from Baekje.
According to the Nihon Shoki, Emperor Kinmei received a bronze statue of Gautama Buddha as a gift from King Song Myong (èÂÂæÂÂçÂÂ, Seimei à Â) of Baekje, alongside a significant envoy of artisans, monks, and other artifacts in 552. Though some regard this event as the official introduction of Buddhism to Japan, texts such as the Jà Âgà « Shà Âtoku Hà Âà  Teisetsu indicate Buddhism may have been introduced as early as 538.
The advent of Buddhism across the Japanese Archipelago contributed to a deep rift between the Mononobe clan, whose members supported the worship of Japan's traditional deities, and the Soga clan, whose members supported the adoption of Buddhism.
According to the Nihon Shoki, Emperor Kinmei ruled until his death in 571. Although the text states that Emperor Kinmei was buried in the , the current scholarly consensus instead holds that he is more likely to have been buried in the , located in .
The Emperor is traditionally venerated at a memorial Shinto shrine (misasagi) at Nara. The Imperial Household Agency designates the Nara location as Kinmei's mausoleum, and is formally named Hinokuma no saki Ai no misasagi. Its status as the emperor's actual resting place, alongside other graves of the early Emperors, are held in dispute by some historians and archaeologists.
Emperor Kinmei's father was Emperor Keitai and his mother was Emperor Ninken's daughter, . In his lifetime, he was known by the name .
Kinmei had six Consorts and 25 Imperial children (16 sons and 9 daughters). According to Nihongi, he had six wives, but the Kojiki gives only five wives; identifying the third consort to be the same as the sixth one. The first three were his nieces, daughters of his half-brother Emperor Senka; two others were sisters, daughters of the Omi Soga no Iname.
