Fujiwara no Michitsuna no Haha was a waka poet in the Mid Heian period. She was in her mid-thirties when she began to write her journal Kagerō Nikki, written in a combination of waka poems and prose. Her diary gave access to a woman's experience of a thousand years ago, with poems she recorded which vividly recall the past. These poems conveyed the life of a noblewoman during the Heian Period. She is one of the Nihon Sandai Bijin. Her true name is unknown to history.
