Fujiwara no Yoshifusa (藤原 良房, 804 – October 7, 872), also known as Somedono no Daijin or Shirakawa-dono, was a Japanese statesman, courtier and politician during the Heian period.[1]
When Yoshifusa's grandson was enthroned as Emperor Seiwa, Yoshifusa assumed the role of regent (sesshō) for the young monarch.[1] He was the first sesshō in Japanese history who was not himself of imperial rank; and he was the first of a series of regents from the Fujiwara clan.[1]
