The Keichō Tsūhō was among the first coins issued under Tokugawa authority following the consolidation of power after Sekigahara in 1600, part of a deliberate effort to standardize a monetary system that had long relied on imported Chinese cash coins — particularly Ming-era Eiraku Tsūhō — circulating alongside a chaotic assortment of private and domain issues. Production was authorized in 1606 under the second shogun Tokugawa Hidetada, with casting carried out at multiple furnaces across Japan, which accounts for the considerable variation in fabric and flan quality seen across the DHJ subtype range.
