50 Sen - Shōwa Imperial Japanese Government

P#60 belongs to the final phase of wartime and immediate postwar Japanese fractional currency — a period when the government was printing notes to cover spending it could no longer finance through taxation or borrowing. By 1945 the Bank of Japan's printing infrastructure had been severely disrupted by Allied bombing, and production quality across multiple series declined noticeably toward the end of the run.

The date range straddles surrender. Notes from this type circulated under two entirely different political realities without any change in design, which the Occupation authorities permitted temporarily while scrambling to introduce replacement issues.
