This series was printed to replace the Indian Rupee that had circulated under British colonial rule. The notes were issued without signatures or dates and circulated alongside military scrip. After Japan's defeat in 1945, the currency became worthless. The 'BD' block letters likely indicate a specific printing series or distribution zone. These notes are documented as Pick M-series (M for Military) in the Standard Catalog. The lack of sophisticated security features and the propaganda nature of the design—showing Buddhist temples under 'Japanese Government' authority—are characteristic of wartime occupation issues.

The Sacuanjoche (Plumeria rubra), Nicaragua's national flower since 1971, is prominently featured. Small fractional notes like this were eventually withdrawn from circulation as inflation continued, though the córdoba remains Nicaragua's currency.
