Issued by Japan in 1958 to commemorate the 3rd Asian Games held in Tokyo, this striking 24-yen stamp highlights the sport of diving through a stylized athlete in mid-motion against a bold blue background. The design reflects the modern graphic style popular in mid-20th-century Olympic and sports philately. Featuring the official Asian Games emblem and bilingual inscriptions, the stamp forms part of Japan’s important early international sporting commemoratives. It is highly collectible among thematic collectors focusing on Olympics, sports, and Asian Games issues, as well as Japan mid-century commemorative sets.
