The Qing empire and Japan signed the Treaty of Shimonoseki ending the First Sino-Japanese War. Under the treaty, Qing China ceded Taiwan and the Pescadores (Penghu) to Japan. This diplomatic decision set the legal basis for Japan’s takeover and the start of five decades of colonial rule.
Japan created the post of Governor-General of Taiwan to run the new colony and appointed Admiral Kabayama Sukenori as the first holder. The Governor-General’s office became the central authority for policing, taxation, infrastructure, and later programs aimed at reshaping Taiwanese society. This institution anchored Japan’s colonial state on the island.
Local elites proclaimed the Republic of Formosa in Taipei as a last-ditch effort to resist Japan’s takeover after the treaty. Although short-lived and not widely recognized internationally, it organized armed resistance and shaped the early conflict over control of Taiwan. Its rapid collapse helped Japan justify stronger military and police measures.
Japanese troops landed in northern Taiwan to occupy the ceded territory, sparking the main fighting of the 1895 invasion. Resistance combined former Qing units, local militias, and other groups opposing the transfer. The campaign’s outcome determined whether Japan could convert treaty claims into real control on the ground.
Tainan’s capitulation marked the collapse of the Republic of Formosa and the end of organized military resistance in the invasion’s main phase. With major towns secured, Japan began building a long-term colonial administration backed by police and military power. Local unrest continued in different forms, but Japan’s island-wide rule had effectively begun.
The Tapani Incident was a major armed uprising against Japanese authorities, centered in southern Taiwan. It involved both Han Taiwanese and Indigenous participants and was met with forceful suppression by colonial police and military units. The revolt showed that resistance remained possible decades after annexation, and it influenced later security policies.
Taiwanese intellectuals founded the Taiwanese Cultural Association to promote social education and public discussion under colonial rule. Rather than armed revolt, it used lectures, publications, and organizing to build a sense of shared Taiwanese identity and to press for reforms. This marked a shift toward modern civic and political activism in the colonial era.
Japan founded Taihoku (Taipei) Imperial University, Taiwan’s first university, as part of its colonial education system. The institution trained professionals and supported research that served colonial administration and development. It also became a lasting legacy, later reorganized after 1945 as National Taiwan University.
Seediq (Indigenous) fighters attacked Japanese in Musha in October 1930, and the colonial government responded with a large-scale crackdown. The incident became the last major armed uprising against Japanese rule in Taiwan. Its aftermath drew criticism and led to changes in how the colonial state managed Indigenous communities.
After the outbreak of the Second Sino-Japanese War, Japan intensified assimilation policies in Taiwan under the Kominka movement. The campaign pushed Taiwanese residents to act as loyal imperial subjects through measures such as promoting Japanese language and identity and increasing state control over daily life. These policies tied Taiwan more tightly to Japan’s wartime mobilization.
During World War II, Japan began allowing ethnic Taiwanese to join the imperial armed forces as combat volunteers, a major change from earlier restrictions. This widened Taiwan’s role in Japan’s war effort and further integrated the colony into imperial mobilization. It also shaped postwar memories, as many families were affected by wartime service and loss.
On October 25, 1945, Japanese representatives in Taiwan surrendered to Republic of China representatives in Taipei, marking the end of Japanese colonial administration. This event is commonly associated with Taiwan coming under ROC control and the transition into a new postwar political era. The handover closed the 1895–1945 period of Japanese annexation and rule.
