The Fujiwara clan's control over Japan and its politics reached its zenith under his leadership.

Michikane then succeeded him, famously ruling as Regent for only seven days before he too died of disease.

With his two elder brothers dead, Michinaga then struggled with Fujiwara no Korechika, Michitaka's eldest son and the successor he had named.

Korechika's position was ruined by a scandal that took place the following year, likely arranged by Michinaga.

Though the jurists examining the case found the servants of Kaneie and Takaie at fault.

During their struggle, Michinaga had gained the position of Minister of the Right, or Udaijin (右大臣), on the 19th day of the 6th month of 995.

Later, in 996, Michinaga became Minister of the Left, Sadaijin (左大臣), the most senior position in government apart from that of Chancellor (Daijō-daijin).

The youth of Go-Ichijō meant that Michinaga ruled as Sesshō, the Regency assumed.

He left a diary, the Midō Kanpakuki, which is about the Heian court at the height of Fujiwara power.
