Editing Emperor Keikō (section)

==Known information==
Emperor Keikō is regarded by historians as a "legendary Emperor" as there is insufficient material available for further verification and study.<ref>{{cite web|url=http://www.t-net.ne.jp/~keally/kofun.html|title=Kofun Culture|author=Kelly, Charles F.|work=www.t-net.ne.jp|access-date=May 28, 2019}}</ref> The name Keikō''-tennō'' was assigned to him [[Posthumous name|posthumously]] by later generations.<ref name="name">{{cite book|url=https://archive.org/details/ahistoryjapanes00kikugoog|title=''A History of the Japanese People from the Earliest Times to the end of the Meiji Era''|author=Brinkley, Frank|publisher=Encyclopaedia Britannica Company|year=1915|page=[https://archive.org/details/ahistoryjapanes00kikugoog/page/n33 21]|quote=Posthumous names for the earthly ''Mikados'' were invented in the reign of Emperor Kanmu (782–805), i.e., after the date of the compilation of the ''Records'' and the ''Chronicles.''|author-link=Francis Brinkley}}</ref> His name might have been regularized centuries after the lifetime ascribed to Keikō, possibly during the time in which legends about the origins of the [[Imperial House of Japan|imperial dynasty]] were compiled as the chronicles known today as the ''[[Kojiki]]''.<ref name="aston109 & 188-214"/> There is a possibility that Keikō's era was in the 4th century AD rather than the 1st.<ref>{{cite book|url=https://books.google.com/books?id=pS06JeJkI0IC&q=emperor+keiko+4th+century|title=Japan Review: Bulletin of the International Research Center for Japanese Studies, Issue 1|year=1990|publisher=International Research Center for Japanese Studies|page=37|access-date=July 30, 2019}}</ref> This period is concurrent with the [[Japanese missions to Imperial China|Kentoshi]] having an audience with the Tang Emperor, though more evidence is needed to make any conclusions. Like his father before him, Keikō is also known to have an exaggerated lifespan which is unlikely to be factual. The consecutive reigns of the emperors began to be compiled in the 8th century, and it is thought that age gaps were "filled up" as many lacunae were present.<ref>{{Cite EB1911|wstitle= Japan/09 Domestic History |volume= 15 |last= Brinkley |first= Francis |author-link= Francis Brinkley | pages = 252&ndash;273; see page 253 }}</ref><ref>{{cite book|url=https://books.google.com/books?id=8ng_AQAAMAAJ&q=emperor+keiko+longevity&pg=PA591|title=The New Werner Twentieth Century Edition of the Encyclopaedia Britannica: Volume 13|publisher=Werner Company|year=1906|page=591|access-date=July 30, 2019}}</ref> For comparison, verified ages in the 110s have since been documented and [[List of the verified oldest people|recorded]] as the "oldest in the world".

While the actual site of Keikō's [[grave (burial)|grave]] is not known, the Emperor is traditionally venerated at a [[memorial]] [[Shinto]] [[shrine]] (''misasagi'') at [[Nara, Nara|Nara]]. The [[Imperial Household Agency]] designates this location as Keikō's [[mausoleum]], and it is formally named ''Yamanobe no michi no e no misasagi''.<ref name="kunaicho"/><ref name="Fane1953"/> Outside of the ''Kiki'', the reign of [[Emperor Kinmei]]{{efn|The 29th Emperor<ref name="Titsingh"/><ref name="Brown"/>}} ({{circa|509}} – 571 AD) is the first for which contemporary historiography has been able to assign verifiable dates.<ref>{{cite book|url=https://books.google.com/books?id=axRyAAAAMAAJ&q=According+to+legend%2C+the+first+Japanese+Emperor+was+Jimmu.+Along+with+the+next+13+Emperors%2C+Jimmu+is+not+considered+an+actual%2C+historical+figure.+Historically+verifiable+Emperors+of+Japan+date+from+the+early+sixth+century+with+Kimmei.|title=''Japanese Politics: Fixed and Floating Worlds''|author=Hoye, Timothy.|publisher=Prentice Hall|year=1999|page=78|quote=According to legend, the first Japanese Emperor was Jimmu.
