| Additional information |
The Jōwashōhō was the sixth coin issued under Japan's Kōchōjūnisen system — a succession of twelve imperial copper issues spanning 708 to 963 AD, each progressively debased and increasingly ignored by a populace that preferred rice and silk as exchange media. By the time of Emperor Ninmyō's reign, imperial coinage had already lost most of its practical credibility, with provincial populations routinely refusing state-minted copper in favor of commodity barter. The coins were still produced, and official edicts still demanded their acceptance, but enforcement was largely theater.
