[citation needed] During the Japanese era (1895–1945), Jiji was a collection and shipping export point for camphor produced in the surrounding areas.

The 2014 mayoral election was won by 29-year-old Chen Chi-heng of the newly formed Trees Party, in what was characterized by the media as a surprise.
