Japanese currency started to be made, with the minting of local coins, sometimes in gold. Especially the Takeda clan of Kōshū minted gold coins which were later adopted by the Tokugawa shogunate. Hideyoshi unified Japan, and thus centralized most of the minting of large denomination silver and gold coins, effectively putting in place the basis of a unified currency system. Hideyoshi developed the large Ōban plate, also called the Tenshō Ōban (天正大判), in 1588, a predecessor to Tokugawa gold coinage. A common practice in that period was also to melt gold into copper molds for convenience, derived from the sycee manufacturing method.
