| 背面描述 | Plain reverse with a central square perforation flanked by a raised inner rim and an outer raised border encircling a flat, unadorned field. No inscription, decoration, or additional design elements are present, consistent with standard Japanese imperial cast cash coinage of the late Heian period. The surface exhibits a uniform dark brown and grey patination with scattered red cuprite deposits. |

The Kanpyōtaihō takes its name from the Kanpyō era of Emperor Uda's reign, and it was among the last of Japan's twelve imperially-sanctioned copper cash coins — the Jūnisen — struck before the imperial court abandoned copper coinage entirely for nearly six centuries. The decision to stop minting wasn't gradual deterioration but a deliberate withdrawal: by the late Heian period, rice and cloth had reasserted themselves as the dominant exchange media, and imported Chinese coin filled whatever gaps remained.
