| Additional information |
The large-type 5 Sen was a short-lived design casualty of World War I. Japan's copper-nickel supply came under strain as the war drove global demand for industrial metals, and the Mint experimented with proportions before settling on a reduced type that replaced this issue by 1920. The large format was never revisited.
