三輪山
, also known as in the "Kojiki", and or in the "Nihon Shoki" was the tenth Emperor of Japan. While Sujin is the first emperor whose existence historians widely accept, he is still referred to as a "legendary emperor" due to a lack of information available and because dates for his reign vary. Both the "Kojiki", and the "Nihon Shoki" (collectively known as the "Kiki") record events that took place during Sujin's alleged lifetime. This legendary narrative tells how he set up a new shrine outside of the Imperial palace to enshrine Amaterasu. He is also credited with initiating the worship of Ōmononushi (equated with the deity of Mount Miwa), and expanding his empire by sending generals to four regions of Japan in what became known as the legend of "Shidō shogun".
