The results of the land ownership survey (土地調查) and forest arrangement (林野整理) made the traditional lifeway of the Amis far-reaching effects during the Japanese rule.

For the Japanese, the results of the land ownership survey (土地調查) and forest arrangement (林野整理) enhanced the control of the Amis and their land.

But the Japanese partitioned the co-ownership into individual ownership, and then the correlative conventionalities were changed in the meantime.
