 Over the course of the Edo period, the entire economy would not only shift from rice to coin, but would also see the introduction and spread of paper money initiated and facilitated by the men of Dōjima.The year 1710 marks the beginning of this development, which also brought with it the emergence of the concept of trading in futures (延べ米"nobemai").The Osaka merchants, like the Kyoto rice brokers three hundred years before, developed an increasingly monopolistic grasp on the rice trade, determining prices not only within Osaka, but in the entire Kinai (Home Provinces) area, and indirectly having a great effect on prices in Edo.
