The Kutsuki were a branch of the Sasaki family hailing from Omi Province. They served as the stewards of the Kutsuki manor in that province in the Kamakura period, and the house continued through the Warring States period and into the Edo period, when some of their members became bannermen (direct vassals of the shogun) or daimyo (provincial lords). "The archives of Kutsuki family" consist of historical documents passed down in the family through the years. The Cabinet Records Bureau purchased them from the Kutsuki in 1888. Containing more than 1,060 documents, the archives were designated an important cultural property in the first year of Heisei( 1989).
An imperial order of Emperor Kogon (1313 - 1364) dated 23 September in the first year of Syokei(1332). It was written in response to a claim by Kutsuki Tokitsune that family territory in Okanarimyo and other parts of Etchu Province was being unlawfully seized and devastated, and instructs him to take action against this behavior.
