Competition for POJ was introduced during the Japanese era in Taiwan (1895–1945) in the form of Taiwanese kana, a system designed as a teaching aid and pronunciation guide, rather than an independent orthography like POJ. From the 1930s onwards, with the increasing militarization of Japan and the movement encouraging Taiwanese people to "Japanize", there were a raft of measures taken against native languages, including Taiwanese. While these moves resulted in a suppression of POJ, they were "a logical consequence of increasing the amount of education in Japanese, rather than an explicit attempt to ban a particular Taiwanese orthography in favor of Taiwanese kana".
