7-ELEVEN 統一超商

7-Eleven is the largest convenience store chain In Taiwan, and is owned by President Chain Store Corporation under Uni-President Enterprises Corporation. The first fourteen stores opened in 1979, and struggled to make a profit. Southland Corporation partnered with Uni-President to modernize the stores. However, business was still slow, and Uni-President opted to stock Asian foods. In 1986, 7-Eleven made its first profit in Taiwan. The 5,000th store was opened in July 2014. In January 2018, an experimental and unstaffed shop branded the X-Store was opened. 7-Eleven announced plans to operate a combination store in partnership with Domino's Pizza in February 2019.

In the early 2000s, 7-Eleven introduced a corporate mascot named Open-Chan (Open 小將), an extraterrestrial dog who wears a rainbow-shaped crown from a fictional planet known as Planet Open to be a "cartoon spokesperson" for the store chain in Taiwan. Open-Chan quickly grew in popularity among Taiwanese children soon after its initial debut. After Open-Chan's subsequent rise to prominence in Taiwan, the character was even introduced in Japan.
