・【Bitasen (Debased Coins)】
Bitasen refers to a collective term for low-quality or debased coins that circulated in Japan from the late medieval period through the early Edo period.
Meaning and Etymology
The word bita (鐚) means “inferior” or “poor quality.”
Thus, bitasen describes coins that were inferior in metal content, weight, and reliability compared to officially issued currency.
Characteristics
• Low copper content, often mixed with lead or iron
• Lightweight and poorly cast
• Blurred or crude inscriptions
• Visually similar to official coins but with significantly lower value
Historical Background
• Shortage of copper in Japan during the late Muromachi period
• Widespread private minting (unauthorized coin casting)
• Poor imitations of imported Chinese coins, such as Yongle Tongbao
• Economic disruption caused by continuous warfare during the Sengoku period
Economic Impact
• Markets distinguished between good coins (seisen) and debased coins (bitasen)
• Exchange rates emerged (e.g., several bitasen equaling one standard coin)
• Trade inefficiency and inflation increased
• Bitasen symbolized a collapse of monetary trust
