意味

Daily interest rate. The amount of interest accrued per day, expressed as a rate per unit of principal.

Traditionally expressed as a rate per 100 yen per day (e.g. 日歩5銭 = 0.05 yen per 100 yen per day, equivalent to roughly 18.25% per annum). A system rooted in pre-war Japanese lending practices that persisted in consumer finance and loan agreements well into the postwar era. Now largely superseded by annual percentage rate (年利) notation, but still appears in older contracts, legal disputes, and historical finance texts.
