The Japanese rulers renovated the houses in Chinese residential areas (for reasons of public health). They also mapped out several residential areas for Japanese immigrants. Because the flow of Japanese into Taipei was slow and steady, the city's growth could be kept within the constraints of the plan.
除在中國人住的區域，以衛生理由進行房屋重建，日本人也另外規劃一些住宅區給日本移民居住，由於日本人進入台北的速度較穩定，都市因此能在計畫控制下發展。
