Fujiwara no Koretada

Fujiwara no Koretada (藤原 伊尹; 924–972), also known as Fujiwara no Koremasa or Kentokuko, Ichijō sesshō and Mikawa-kō, was a Japanese statesman, courtier, politician and waka-poet during the Heian period.
His poems were published in "The Collected Poems of the First Ward Regent", Ichijo Sessho Gyoshu, and in Hyakunin Isshu (poem No. 45).

Emperor Murakami named Koretada conservator of Japanese poetry in 951.

Koretada served as a minister during the reign of Emperor En'yū.

• 970 (Tenroku 1, 1st month): Koretada is named udaijin.
• 970 (Tenroku 1, 5th month): After the death of Fujiwara no Saneyori, Koretada is named sesshō (regent).
• 971 (Tenroku 2, 11th month): Koretada assumes the office of daijō daijin.
• 972 (Tenroku 3, 5th day of the 1st month): The enthronement of Emperor En'yu is supervised by Koretada.
• 972 (Tenroku 3, 11th month): Koretada died at age 49; and he was posthumously raised to first class rank. He was granted the posthumous title of Mikawa-kō.

The immediate consequence of Koretada's death was a period of intense rivalry between his brothers Kanemichi and Kaneie.

This member of the Fujiwara clan was the son of Morosuke. He was the oldest son; and became head of the Hokke branch of the clan after his uncle Saneyori died in 970.

Koretada had four brothers: Kaneie, Kanemichi, Kinsue, and Tamemitsu.
