Another major cause for inflation was that from 1859 local Daimyō started minting their own coinage often with high denominations to increase the money supply or to get more gold and silver for their low copper supplies, in 1862 this inspired Daimyō Shimazu Nariakira to produce "Tenpō Tsūhō" derivatives in the form of 100 on "Ryūkyū Tsūhō" coins and even ½ Shu "Ryūkyū Tsūhō" coins under the pretence of minting coins for their vassal Ryukyu Kingdom, this proved profitable for the Satsuma domain.
