布農族是一支移動性很強的民族，在日治初期對於日本人統治產生很大的威脅；為了統治管理上的需要，日本人開始針對布農族人展開「集團移住」的策略，將他們由幽深高山遷移至較低的山地區域。「集團移住」的結果，促使一些旗山郡的「蕃地」，形成不同族群原住民混居的現象。在日本人的殖民統治下，不管是教育所或是一般社會活動上，這些不同的原住民族主要透過「國語」（日語）來相互溝通與理解，進而促成部落社會的穩定。

Bunun people were a great threat for Japanese colonial government, because they had rapid moving ability on the mountain area in Taiwan. For the governing reason, Japanese utilized the strategy of ‘tribal movement’ on Bunun people and forced to move them from higher mountain to lower hill. The result of ‘tribal movement’ was to form a place where two different indigenous peoples lived together in the indigenous area of Chishan County. In Japanese colonial governing, either at the Indigenous Primary Educational Institutions or social activities, these different indigenous peoples communicated one another with Japanese language, and in advanced to improve social stability.
