Taiwan During World War II. Episodes

By the late 1930s Taiwan had become one of Japan’s most important colonial possessions. It functioned as both an economic supplier and a strategic military base for Japan’s expansion across East and Southeast Asia. Extensive infrastructure, including ports, railways, and airfields, had already been developed during the colonial period, and these facilities allowed Taiwan to serve as a major logistical hub once the Pacific War began in 1941.

As the war intensified, Taiwan’s economy and society were fully mobilized to support Japan’s military needs. Agricultural production, especially rice and sugar, was directed toward feeding Japanese troops and civilians across the empire. Factories were retooled to produce military supplies and processed goods that could be shipped to battlefronts. Colonial authorities also launched assimilation campaigns encouraging Taiwanese people to adopt Japanese names, speak Japanese, and participate in Shinto rituals. These policies were meant to integrate Taiwan more tightly into the imperial state and cultivate loyalty to the emperor. Some local elites cooperated and benefited from economic modernization, while others maintained a distinct Taiwanese identity beneath official pressure to conform.

Mobilization also meant manpower. Hundreds of thousands of Taiwanese men were recruited as laborers, technicians, and eventually soldiers in the Japanese armed forces. Many served in non combat roles such as construction, transport, and communications, though some later joined combat units as the war situation worsened for Japan. Daily life became increasingly controlled. Rationing, surveillance, and civil defense drills became common. Schools taught imperial ideology, and propaganda stressed unity between Japan and its colonies. Even so, enthusiasm for the war varied widely among the population, reflecting a complex mixture of pragmatism, colonial conditioning, and quiet skepticism.

From 1944 onward, Taiwan’s role shifted from secure rear base to vulnerable frontline target. As American forces advanced across the Pacific, they launched heavy bombing raids on key military and industrial sites on the island. Major targets included the harbor at Kaohsiung, air bases near Tainan and Hsinchu, and transportation networks that supported Japan’s regional war effort. These attacks caused widespread destruction and civilian casualties. Air raid sirens, blackouts, and shelter drills became part of everyday life. Food shortages worsened, and the sense of imperial security that had once surrounded Taiwan steadily eroded under the pressure of Allied air power.

The war ended abruptly in August 1945 with Japan’s surrender following the atomic bombings and the Soviet entry into the conflict. Taiwan was handed over to the Republic of China.
