 The shogunate set a price floor in 1735, forcing merchants in Edo to sell for no less than one "ryō" per 1.4 "koku", and in Osaka no less than 42 "momme" per "koku".A 10 "momme" fine was charged of anyone found to have paid less.Over the fifteen years or so, until roughly 1750, the shogunate stepped in on a number of occasions to attempt to stabilize or control the economy.
