In the past all the people of Takangko took part in the Kangko Ami harvest festival. So as to cultivate a centripetal force and with the hope that the young people would not return only for the Spring Festival but also after the summer work in the fields was completed, they decided to hold their own Ami harvest festival.
以往大港口人都參加港口阿美的豐年祭，但為了要培養向心力，希望年輕人除了在春節回家過年外，也能在夏天農作收成後返鄉慶祝阿美的豐年祭。
