Wartime Mobilization
When full-scale war with China broke out in 1937, Taiwan's fate was utterly rewritten. No longer merely the colonial agricultural base of the Japanese empire, it was pushed forward as a frontline springboard for the 'southward advance' into Southeast Asia. Beginning with the last military Governor-General, Kobayashi Seizo, who proclaimed the threefold line of 'imperialization, industrialization, and use as a southward base,' the whole island was progressively remade into an indispensable part of the empire's war machine. The eighteenth Governor-General, Hasegawa Kiyoshi, who succeeded him in 1940, was the key figure who drove this line to its extreme. A Japanese navy admiral by background, he governed Taiwan in the crucial years when the Pacific War broke out in full, and in 1941 he founded the Kominhokokai (Imperial Subjects Public Service Association), enrolling the whole island's population from the top down in a service organization that mobilized manpower, materiel, and spiritual energy in support of the front. Compared with his predecessor he took a somewhat more conciliatory cultural stance, courting the Taiwanese gentry under the slogan of 'Japan and Taiwan as one' in an effort to win their full commitment to the war.
