Nitobe Inazō, a former Director of the Bureau of Industries in the Government of Formosa, wrote, "Though the island was pacified no one knew what was to happen next. We did not understand the character of the people. Very few Japanese could speak Formosan and fewer Formosans could speak Japanese. There was naturally mutual distrust and suspicion. The bandits abounded everywhere. Under these conditions military rule was the only form of government that could be adopted until better assurance could be obtained of the disposition of the people. For this purpose it was calculated that some ten million yen, I may say five million dollars, was yearly needed for the pacification and government of Formosa."
