The Era of Jōwa — Coin Born Amidst Political Turbulence

The year 835, when Jōwa Shōhō was minted, was a significant turning point in Japanese history. At this time, a few years after the ascension of Emperor Ninmyō, the Ritsuryō system began showing signs of decline. Emperor Ninmyō, who ascended as the son of Emperor Saga, sought political stability amidst intensified power struggles among the nobility. On the eve of the Jōwa Disturbance in 838, political tension was high.

In this background, Jōwa Shōhō was minted as a symbol of political stability and economic prosperity. The inscription 'Shōhō' was imbued with a wish for national stability and prosperity, carrying a strong political message. Given that its predecessor, Fujushinhō, was issued in 818, the 17-year interval suggests the issuance of a new currency was an economically necessary decision. Thus, Jōwa Shōhō held significance beyond its role as a mere currency, becoming a symbolic reflection of the political and economic conditions of the time.

The minting of Jōwa Shōhō was a crystallization of the efforts and ingenuity of the artisans of the time. Japanese ancient coins often employed techniques influenced by China, and Jōwa Shōhō was no exception. The exact minting location remains unknown, but it is presumed to have occurred in regions near Nagaoka-kyō or Heian-kyō.

Technologically, an alloy with copper as the main component was used, with the minting process involving pouring molten metal into molds at high temperatures. These molds were precisely crafted by skilled artisans to accurately reproduce inscriptions and designs. The artisans involved had a sense of mission to support national development and stability, operating under circumstances that allowed no failure.

The minting of Jōwa Shōhō was also heavily influenced by the economic policies of the time. Against a backdrop of financial distress, the aim was to invigorate the monetary economy with the issuance of coins. Knowing the minting process of Jōwa Shōhō provides valuable insights into the technical levels and social contexts of ancient Japan.

The Shrinking Circulation Range — Market and Public Response

The economic situation from 835 to 848, during which Jōwa Shōhō was minted, changed alongside the decline of the Ritsuryō system. Even in this era when the monetary economy was being established, the circulation of Jōwa Shōhō reportedly remained limited. This indicates financial stringency and questioned the reliability of the coins themselves.

At the time Jōwa Shōhō was issued, bartering was still common among the populace, and the use of currency was confined to urban areas or some wealthy individuals. Thus, the limited circulation range is understandable. Moreover, due to price fluctuations and distrust in currency value, dependence on currency was limited.

Economically, the intent was to control inflation and stimulate trade by increasing the amount of currency circulating in the market with coin issuance. However, in reality, the expected effects were limited, and public acceptance of Jōwa Shōhō seemed sluggish. Such economic backgrounds led to later currency re-coinages and abolitions.
