Issued by Japan in 1974, this 20-yen commemorative marks the 61st Inter-Parliamentary Conference held in Tokyo. The design features a stylized double-globe motif symbolizing global cooperation and legislative dialogue among nations. Subtle map outlines and the faint silhouette of Japan’s National Diet Building underscore the host country’s role. Printed in deep green and pale aqua tones, it represents a classic example of Japan’s clean, modern diplomatic-theme designs of the 1970s. A meaningful addition for collectors of international organizations, Japanese commemoratives, and geopolitical themes.
