The original Amis inhabitants allied themselves with the Qing dynasty and against the Sakizaya and Kavalan people during the Takobowan incident [zh] in 1878.
The Amis were underpaid for their services, and organized an uprising [zh], after which the Japanese removed them from the area.
Subsequently, the Governor-General of Taiwan encouraged Japanese to immigrate the regions of Hualien and Taitung and established a village here called Yoshino (吉野) in 1910.
In 1948 after the Kuomintang takeover, to reduce the Japanese flavor of the name, it was renamed as the current Ji'an Township.
