Korean Americans flood Starbucks inbox over 'Tank Day' campaign

Korean Americans are sending a wave of protest emails to Starbucks headquarters in Seattle, angered by a "Tank Day" marketing campaign by Starbucks Korea that they say dishonors the victims of the 1980 Gwangju pro-democracy uprising.

The backlash shows how a marketing misstep in one country can rapidly become a global brand crisis — and how diaspora communities are using coordinated online organizing to hold multinational corporations accountable across borders.

The campaign at the center of the controversy used the phrase "Tank Day" — a term that carries profound historical weight for Koreans as a reference to the military deployment of tanks against pro-democracy demonstrators during the May 18, 1980 crackdown in Gwangju. According to The Korea Times, the campaign triggered boycotts and protests across South Korea and led to the dismissal of Starbucks Korea's chief executive.

Shinsegae Group Chairman Chung Yong-jin, whose conglomerate operates Starbucks Korea, issued a public apology. Starbucks headquarters in the United States acknowledged the seriousness of the complaints and said it was monitoring the situation, The Korea Times reported.

In the United States, the protest has taken organized form through MissyUSA, a widely used online community for Koreans living abroad. Forum members are sharing sample complaint emails in both Korean and English, along with Starbucks contact information, and urging fellow members to write directly to the company's Seattle headquarters.

"I couldn't stay silent after seeing the campaign. On May 18, tanks aren't something people joke about," said a Korean woman surnamed Kim, a Seattle resident, according to The Korea Times. Yoo Jee-hee, 34, of New Jersey, said the controversy has reshaped her view of the brand entirely. "I learned about the Gwangju uprising growing up, so seeing the term 'Tank Day' used so casually was honestly shocking. This doesn't feel like just a Starbucks Korea issue anymore because now the Starbucks name itself is tied to the controversy," Yoo said.

One widely circulated sample email captures the depth of sentiment driving the campaign. "Because of this, I now feel a strong aversion even toward Starbucks coffee in the United States and can no longer bring myself to drink it. From now on, whenever I see the Starbucks logo, I will only be reminded of 'Tank Day,' which causes me great discomfort and disgust," the email reads, according to The Korea Times.

Starbucks has yet to issue a statement directed specifically at Korean Americans, and it remains unclear whether the company plans action beyond monitoring the situation, according to The Korea Times.
