| Obverse description | The obverse features a stylized depiction of the Grand Ring pavilion structure of Expo 2025 Osaka in the upper field, rendered in relief against a horizontally striated background evoking the waters of Osaka Bay. In the right foreground stands Myaku-Myaku, the official mascot of Expo 2025, depicted as a whimsical anthropomorphic figure with a cluster of cell-like spheres forming its head, multiple eyes, and an open smiling mouth. The country name legend 日本国 (State of Japan) is inscribed along the upper rim in Kanji, while the denomination 壱万円 (10,000 Yen) appears in large Kanji characters across the lower field. |

| Additional information |
Japan's commemorative gold program for Expo 2025 Osaka Kansai falls under legislation that permits the Cabinet to authorize special coinage outside the standard Mint Law framework — a mechanism used selectively since the 1964 Tokyo Olympics issue, which marked Japan's first post-war commemorative coin. The Reiwa era designation places this squarely in Emperor Naruhito's reign, which began May 2019 following Akihito's abdication under the 1947 Imperial House Law's first-ever application of voluntary retirement provisions.
At .9999 fineness, this exceeds the .999 threshold common to most sovereign bullion programs.
