5000 Yen - Reiwa 150 years Yen

Issued to mark the 150th anniversary of the yen system, which was established by the New Currency Act of 1871 under the Meiji government — a sweeping monetary reform that abolished the chaotic feudal coinage system of the Tokugawa period and aligned Japan with Western decimal currency standards. The timing of this commemorative falls in the Reiwa era, creating an unusual juxtaposition: a reign-era dating system rooted in centuries of imperial tradition stamped onto a coin celebrating the very modernization that once threatened to dissolve such traditions entirely.
