{{Nihongo|'''Emperor Seimu'''|成務天皇|Seimu-tennō}}, also known as {{Nihongo||稚足彦天皇|Wakatarashi hiko no Sumera mikoto}}, was the 13th [[legend|legendary]] [[Emperor of Japan]], according to the traditional [[List of Emperors of Japan|order of succession]].<ref name="imperial-household-agency-kunaicho-2019a">{{cite web|url=http://www.kunaicho.go.jp/ryobo/guide/013/index.html|title=成務天皇 (13)|work=[[Imperial Household Agency]] (Kunaichō)|language=ja|access-date=31 July 2019}}</ref><ref name="titsingh-isaac-1834a">{{cite book|url=https://books.google.com/books?id=18oNAAAAIAAJ&q=nipon%20o%20dai%20itsi%20ran&pg=PA34|title=Nihon Ōdai Ichiran|author=Titsingh, Isaac.|publisher=Royal Asiatic Society, Oriental Translation Fund of Great Britain and Ireland|language=fr|year=1834|pages=14, 34–36|author-link=Isaac Titsingh}}</ref> Both the ''Kojiki'', and the ''Nihon Shoki'' (collectively known as the ''Kiki'') record events that took place during Seimu's alleged lifetime. This legendary Emperor is best known for organizing his local governments by making the first appointments of their kind to provinces under his rule. Seimu had only one recorded wife who bore him a single child; he also had a concubine but she had no children. This is in stark contrast to his father, who is said to have had at least 80 children with multiple wives.

Seimu's reign is conventionally considered to have been from 131 to 190 AD. An issue ultimately occurred when his only son allegedly died at a young age.<ref>{{cite book|url=https://books.google.com/books?id=SLAeAAAAMAAJ&q=Suinin|title=''The Imperial House of Japan''|author=Ponsonby-Fane, Richard|publisher=Ponsonby Memorial Society|year=1959|page=34|author-link=Richard Ponsonby-Fane}}</ref> Seimu appointed [[Emperor Chūai|one of his nephews]] to be crown prince before his death in 190 AD, marking the first of later generations which would cede the throne to a non-direct successor. While the location of Seimu's grave (if any) is unknown, he is traditionally venerated at a [[memorial]] [[Shinto]] [[kofun|tomb]]. Modern historians have come to the conclusion that the title of "Emperor" and the name "Seimu" was used by later generations to describe this legendary Emperor. It has also been proposed that Seimu actually reigned much later than he is attested.
