Emperor Suinin

Emperor Suinin (垂仁天皇, Suinin-tennō), also known as Ikumeiribikoisachi no Sumeramikoto (活目入彦五十狭茅天皇) was the 11th legendary Emperor of Japan, according to the traditional order of succession. There is less known about Suinin than his father, and likewise is also considered to be a "legendary emperor". Both the Kojiki, and the Nihon Shoki (collectively known as the Kiki) record events that took place during Suinin's alleged lifetime. This legendary narrative tells how he ordered his daughter Yamatohime-no-mikoto to establish a new permanent shrine for Amaterasu (the Sun Goddess), which eventually became known as the Ise Grand Shrine. Other events that were recorded concurrently with his reign include the origins of Sumo wrestling in the form of a wrestling match involving Nomi no Sukune.
