The Dairy of Sanuki no Suke was written by a maid serving the Emperor of the Heian period. At the same time as she served the Emperor, she was involved in court rituals. There is no other diary written by a woman in such a position. In this respect, it can be said that this work is a valuable historical material, but many researchers have not noticed this fact.
Therefore, in this paper I will verify the historical value of this work and also verify the problems. I also consider how this work is appreciated and properly operated as a historical material.
