About Sujin

Emperor Sujin , also known as Mimakiirihikoinie no Mikoto (御眞木入日子印恵命) in the Kojiki, and Mimakiiribikoinie no Sumeramikoto (御間城入彦五十瓊殖天皇) or Hatsukunishirasu Sumeramikoto (御肇國天皇) 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 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, and expanding his empire by sending generals to four regions of Japan in what became known as the legend of Shidō shogun.
