money lent at daily interest
Historical term for a high-interest loan where interest was calculated daily, often associated with Edo-period moneylending. The kanji 烏 (crow) may derive from the image of crows returning to their nests at dusk, suggesting the daily repayment cycle.
In the Edo period, there existed high-interest loans called karasugane, with daily interest.
The word karasugane is now only seen in historical documents.
