The Japanese proletariat writer Sata Ineko(1904-1998), is known for her attentiveness to questions of class and gender through social critique in the form of creative writings. Her "Travel in Taiwan" emerged out of an invitation by Japan News Press to visit Taiwan in 1942. The four essays of the collection record as well as reflect the situation of Taiwan the colony from the perspective of social welfare. Apart from bringing reflections on imperial invasions, its recognition of class and gender also impacted the situation and affections of the Japanese living in Taiwan. This article examines the phenomenon of writing in "Travel in Taiwan" from the viewpoint of colonial consciousness, the imperial reflections on Taiwan's industrialization and imperialization, and issues on class and gender. It concerns how Ineko's attentiveness to class and gender and her involvement in army recuitment have demonstrated a sense of tension, opposition and contemplation. Yet in "Travel in Taiwan," Ineko's final claim of humanism, though echoing the author's claim of proletarian writing, possibly reduces its critique of colonial reality. Such sympathetic writings with public values cannot but being intervened or interfered by imperial colonialism. The conflict between sympatheric public writings and nationalism hence constitute a major tension in the writings on Taiwan in "Travel in Taiwan."
