5 Rin - Taishō

The 5 Rin bronze issues of the Taishō period were produced during Japan's rapid wartime industrial expansion, when copper and bronze allocations were already under strain from military procurement. Taishō-era coinage is often overshadowed by the more widely collected Meiji series, but the 1916–1919 window sits at a peculiar administrative juncture — Emperor Yoshihito's reign had begun in 1912, yet mint production priorities shifted considerably once Japan entered World War I on the Allied side and began supplying munitions across the Pacific theater.

Bronze composition was abandoned for smaller denominations within years of this issue's conclusion, making this among the last of its type in the traditional alloy.
