| Additional information |
Issued under Toyotomi Hideyoshi's authority in 1587, the Shōseigenpō coinage was part of a broader campaign to assert centralized control over Japan's fragmented monetary system following decades of Sengoku-period warfare. Regional lords had long issued their own currencies, and Hideyoshi's gold issues were a deliberate assertion of national economic authority at a moment when unification was still militarily incomplete.
Production occurred at the Fushimi mint under close supervision. Surviving examples are rare; most entered hoards or tribute payments rather than street circulation.
