In brief
In May 2026, Starbucks Korea launched a promotional coffee tumbler called "Tank Day" tying the concept to the Gwangju Uprising anniversary, sparking a nationwide boycott and political uproar. The marketing misstep, viewed as a tribute to tanks used in the 1980 massacre, prompted criminal complaints and a police raid on the company's Seoul headquarters over defamation claims. Within weeks, Shinsegae – the owner of Starbucks in Korea – conducted an internal inquiry, apologized, closed stores for a day to allow staff history lessons, and fired the chain’s chief executive. The incident inflamed partisan divides, with President Lee Jae‑myung condemning the promotion and opposition figures using Starbucks cups symbolically against her administration. The saga underscores the delicate intersection of corporate marketing and national historical memory in South Korea.
South Korean police raided the national headquarters of Starbucks over defamation claims. The raid followed the chain’s controversial "Tank Day" promotion released on the anniversary of the 1980 Gwangju Uprising.
The campaign featured a coffee tumbler titled "Tank Day" and a tagline mimicking a slapping sound, which many interpreted as a reference to tanks that were used to crush pro‑democracy demonstrators in Gwangju. The resulting backlash sparked a mass boycott movement across the nation.
Starbucks Korea quickly rolled back the product and denied any intent to offend, but civic groups filed a criminal complaint, demanding police investigate the company for defaming victims of the military dictatorship.
Shinsegae Group – which operates Starbucks in Korea – announced an internal investigation. It concluded the mistake was unintentional, noting that the design team failed to recognise the historical context and that upper management also overlooked the implication.
In June, all Starbucks stores nationwide closed for half a day so staff could attend mandatory history lessons about the Gwangju Uprising.
The chain’s apology and the promotion’s fallout led to a severe decline in sales in South Korea, one of Starbucks’ largest markets, culminating in the dismissal of its chief executive.
