There are history of law system, economic history and history of city for the field of the study which made medieval “Doso” the material. Understanding about “Tsuchikura” in the present study is based on a study of Takeshi Toyoda and Takahiro Okuno. We assume that “Doso” is “usurer capitalist”, “usurer's pronoun”, “financial institution” and “representative of quality business” according to a study of Toyota and Okuno who become an established theory.
On the other hand, a priest in Kyoto, a priest in an exist place, a seigneur, a merchant, a warrior, a court noble and their vassal give the same thing as a chosen financial act to “Doso”. Though a previous study has classified “Doso” as a moneylender and a pawnbroker.
The purpose on writing is based on such study situation, and considers the reason that “Doso” started to be understood as a moneylender. I look for origin of interpretation about “Doso” Toyota and Okuno made the premise in particular.
The result is as follows. The theory about “Doso” is what Arai Hakuseki of the Edo period argued. The theory he had taught turned out to be misreading of historical materials. That theory was handed down to Yokoi at the wintertime, a scholar of the Meiji era. And the theory of Yokoi at the time of winter was published in the encyclopedia “古事類苑”. And it was passed on to the current common belief.
