Editing Emperor Kōshō (section)

==Known information==
The existence of at least the first nine Emperors is disputed due to 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 8, 2019}}</ref> ''Kōshō'' is thus regarded by historians as a "legendary Emperor", and is considered to have been the fourth of [[Nihon Shoki#Kesshi Hachidai|eight Emperors without specific legends associated with them]].{{efn|Also known as the {{Nihongo|"eight undocumented monarchs"|欠史八代|''Kesshi-hachidai''}}.<ref name="aston">{{cite book|url=https://books.google.com/books?id=_oEfAAAAYAAJ|title=Nihongi: Chronicles of Japan from the Earliest Times to A.D. 697, Volume 2|author=[[William George Aston|Aston, William George.]]|publisher=The Japan Society London|date=1896|pages=109, 144–145|isbn=978-0-524-05347-8 }}</ref>}} The name Kōshō''-tennō'' was assigned to him [[Posthumous name|posthumously]] by later generations, and literally means "filial manifestation".<ref>{{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=[[Francis Brinkley|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.''}}</ref> His name might have been regularized centuries after the lifetime ascribed to Kōshō, 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="aston"/> While the actual site of Kōshō's [[grave (burial)|grave]] is not known, the Emperor is traditionally venerated at a [[memorial]] [[Shinto]] [[shrine]] (''misasagi'') in [[Gose, Nara|Gose]].<ref name="kunaicho"/> The [[Imperial Household Agency]] designates this location as Kōshō's [[mausoleum]].
