Toucheng was formerly called Thau-ui (Chinese: 頭圍; Pe̍h-ōe-jī: Thâu-uî). Toucheng Township (頭城鄉) was established on 9 September 1946. Toucheng Township was upgraded to an urban township (頭城鎮) on 1 January 1948.[4]
The township has recently seen a marked increase in tourism due to the opening of the Freeway 5 linking it with western Taipei. The freeway consists of a series of tunnels dug through the Snow Mountains, the longest of which measures 12.7 km (7.9 mi). The distance between western Taipei and Toucheng is now 30 km (19 mi) and takes roughly thirty minutes of driving, compared to several hours in the past.
