Fujiwara no Yoshifusa
Japanese noble (804-872)

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.
When Yoshifusa's grandson was enthroned as Emperor Seiwa, Yoshifusa assumed the role of regent (sesshō) for the young monarch. 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.
Career
He was a minister during the reigns of Emperor Ninmyō, Emperor Montoku and Emperor Seiwa.

October 7, 872 (Jōgan 14, 2nd day of the 9th month): Yoshifusa died at the age of 69.
Yoshifusa conceived the programme of boy-sovereigns with Fujiwara regents; and his adopted son, Mototsune, carried out the plans.

Why this record matters
The subject matters to the general reference register because the source frames it as japanese noble (804-872). Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jun 22, 2026. The linked authority identifier is Q960841. VIAF identifies the subject as 112351019. The Library of Congress control number is nr2001024381. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
