50 Sen 'Fuji-Sakura'

The 1938 Japanese wartime sen denominations were printed domestically by the Cabinet Printing Bureau as Japan's military expenditures strained the currency supply — the light paper and simplified intaglio work on this series reflect deliberate production economies made under those pressures. The Bureau was already being tasked with printing occupation scrip for China and Manchuria alongside domestic issues, and the workload showed.

Sen-denomination notes had largely been a rarity in Japanese daily life before the late 1930s; coin shortages driven by wartime metal requisitions pushed paper into fractional use for the first time at scale.
