1000 Yen - Heisei Paralympics

Japan issued a series of commemorative 1000 yen silver pieces for the 2020 Tokyo Olympics and Paralympics cycle, with production beginning well ahead of the games themselves — the 2016-dated Paralympic issues were among the earliest in that program. The Tokyo 2020 games were ultimately postponed to 2021 due to the COVID-19 pandemic, giving this coin the peculiar distinction of being struck five years before the event it commemorates.
