In 1871, a ship traveling from Miyako Island to Shuri to deliver annual tribute was caught in a storm and drifted to southern Taiwan. Onboard were 69 Ryukyuan passengers who reached an area inhabited by the Paiwan people. However, some Ryukyuans were killed in a tragic incident that later became known as the Mudan Incident. This event was used as a pretext for Japan’s invasion of Taiwan (the 1874 Taiwan Expedition) and also influenced Japan’s annexation of Ryukyu, significantly shaping the geopolitical landscape of East Asia.
