Fujiwara no Michikane
Fujiwara no Michikane (961–995) was the third son of Fujiwara no Kaneie and a mid-Heian courtier. In 986 he played the key part in unseating Emperor Kazan: when the emperor, mourning his consort Yoshiko, was persuaded to renounce the world, Michikane escorted him secretly from the palace to take the tonsure, then left without keeping his own vow to become a monk, clearing the way for his nephew Emperor Ichijō.
He was promoted udaijin in 994 and succeeded his brother Michitaka as kampaku in 995, but died only seven days later, remembered as the Seven-Day Kampaku.
