| Beschrijving voorzijde | Cast copper cash coin of typical East Asian square-hole type, displaying the four-character reign legend 貞享通寳 (Jōkyō Tsūhō) arranged in the traditional cross-reading order around the central square perforation: 貞 (top), 通 (right), 寳 (left), 享 (bottom). The bold, well-defined characters are rendered in regular script (kaisho) with raised relief against a flat field. A plain raised rim borders the coin, and the surface shows natural olive-brown patina with areas of darker oxidation consistent with age. |

| Aanvullende informatie |
The Jōkyō Tsūhō was introduced in 1684 as part of a broader Tokugawa monetary reform under the fifth shogun Tsunayoshi, intended to standardize the chaotic mix of domestic and imported Chinese cash coins that had circulated in Japan for decades. Imported Kangxi-era Chinese coins and older domestic issues had created persistent quality inconsistencies, and the bakufu's answer was tighter control over copper coinage production at the Nagasaki and Edo mints.
Production was relatively short-lived. Within a generation, the Genbun monetary reforms of the 1730s shifted focus, and the Jōkyō Tsūhō was phased out in favor of successor types.
