100 Yen - Heisei Karate

Issued as part of Japan's Tokyo 2020 Olympic commemorative program — which ran from 2019 through 2021 across multiple series — this piece honors karate in what proved to be a bittersweet context. Karate made its Olympic debut at Tokyo 2020 but was simultaneously excluded from the Paris 2024 program by the IOC, meaning the sport's first and likely only Olympic appearance was already confirmed before the Games even opened.
