Jiji Township (Chinese: 集集; pinyin: jíjí; Wade–Giles: Chi-chi; Pe̍h-ōe-jī: Chi̍p-chi̍p) or Chichi is an urban township located in the west central portion of Nantou County, Taiwan. In past years, the Jiji township encompassed a much larger area and included the present-day Shuili rural township, but today's Jiji is well known as now being, by area, the smallest of Taiwan's townships. The epicenter of the major 1999 earthquake in Taiwan was located in and named after the township. Jiji today is a popular destintation for domestic tourists and daytrippers. The township's famous early-20th-century Japanese-era railway station, the government-run Endemic Species Research Institute, the annual lantern exhibition held during Chinese New Year, as well as other features, attract many weekend visitors. The most popular activity among visitors to Jiji, however, is cycling. Visitors may rent bicycles, tandem bicycles, three-wheeled tricycles or electric-powered bicycles to tour the area's many backroads. A wide selection of local agricultural products can be seen for sale around the township.
In March 2012, it was named one of the Top 10 Small Tourist Towns by the Tourism Bureau of Taiwan.
Han Chinese from Zhangzhou began arriving in the area in 1771. The name originates from "Chiv-Chiv", a phrase in the Formosan languages. During the Japanese era (1895–1945), Jiji was a collection and shipping point for camphor produced in the surrounding areas.
Jiji is bordered by Zhongliao to the north, Mingjian to the west, Zhushan and Lugu to the south, and Shuili to the east. The Zhuoshui River flows westward along the south border of the township. Jiji Township has a total area of 49.72 square kilometres. The lowest point in the township lies at 230 m above sea level and its highest point is Big Jiji Mountain (Jiji Dashan; Shushu Taisan in Japanese) at 1392 m above sea level. The township is very mountainous and is surrounded by mountains on all sides. Climbing up the top of Jiji Dashan, visitors have a great view of the region including the nearby Sun Moon Lake. There are side trails for enthusiastic hikers. During WWII, a U.S. bomber was shot down by the Japanese artillery, and there 4 airmen killed.
