The tone of his descriptions is dry and harsh overall, and critical of the Fujiwara family's Kujo lineage (rivals of Sanesuke's own Ononomiya lineage) but it is especially scathing in its criticisms of both the political decisions and personal life of Michinaga, the head of the Fujiwara family during Sanesuke's lifetime, and furthermore, because the diary covers a lengthy 55 year span, it is possible to achieve a true understanding of the circumstances and Court/military practices of society during the Fujiwara regency period.
