He mainly served the Imperial Court for three generations of Emperors, from Emperor Nakamikado (114th) through Emperor Momozono (116th), and his official court rank was raised to Junii (Junior Second Rank) Gon Chunagon (a provisional vice-councilor of state) (his rank was raised to Shonii [Senior Second Rank] after his death).

He had Naotomo IWAKURA as his adopted child.
