| Reversbeschreibung | Plain reverse exhibiting the characteristic flat, unadorned field of early Japanese cast copper coinage. The central square perforation is framed by a raised square boss, itself surrounded by a broad, smooth inner field and a raised outer rim. No inscriptions, symbols, or decorative elements are present. The surface shows the typical textured finish resulting from the sand-casting process used during the Heian period. |

Eiraku Tsūhō this is not. The Ryūhei Eihō was the third emission in Japan's Kōchōjūnisen series — twelve successive copper coinages issued between 708 and 958 as the imperial court attempted, largely without success, to establish a monetized economy among a population that preferred rice and cloth as exchange media. Kammu's reign saw aggressive fiscal and military expenditure, including the costly campaigns against the Emishi in northern Honshū, and the coinage was partly a mechanism for funding that ambition.
Circulation remained thin outside the capital region. By the time the series ended in the mid-tenth century, the experiment had effectively failed.
