Police raided the national headquarters of Starbucks Korea. The raid followed a wave of defamation allegations linked to a promotional campaign called "Tank Day," which many interpreted as referencing the 1980 Gwangju uprising in which military forces allegedly killed hundreds of pro-democracy protesters.

Starbucks Korea had launched a coffee tumbler promotion on the anniversary of the uprising, using tank imagery and a phrase that sounded like the word "tak," which evoked a controversial police statement from 1987 about a student activist’s death. The marketing move ignited a massive boycott across South Korea and drew criticism from civic groups and the government.

After the boycott’s surge, the Shinsegae Group, which operates Starbucks in Korea, conducted an internal investigation. The company concluded that the promotion was an unintentional mistake and that no one involved had meant to reference the historical event. Nevertheless, it apologized for the inappropriate marketing, acknowledged the decline in sales, and terminated its chief executive.

In response to the backlash, Starbucks closed stores for half a day in June to allow staff to attend history lessons. The incident has become a political talking point, with the president’s office condemning the campaign as insulting to victims and the anti-government opposition using Starbucks cups as symbols of resistance against the ruling party.

This episode underscores the delicate balance companies must keep between marketing creativity and cultural sensitivity, especially in contexts with painful historical memories.
