In a highly anticipated public press conference held in Seoul this Tuesday, the South Korean licensee of Starbucks, Shinsegae Group, laid bare a cascade of systemic errors and oversights that led to the widely condemned ‘Tank Day’ promotional campaign, a misstep that has roiled the country and caused severe reputational and financial damage to the coffee giant’s local operations.
The controversial campaign, which launched a line of insulated ‘tank tumbler’ cups under the ‘Tank Day’ branding, was deliberately scheduled to launch on May 18 — the annual national anniversary of the 1980 Gwangju Pro-Democracy Uprising, where hundreds of unarmed civilians were killed in a violent military crackdown ordered by the then-ruling government. Official records confirm 165 civilians were killed during the crackdown, 65 remain unaccounted for, and 376 more died from injuries sustained in the uprising, though many South Koreans maintain the actual death toll is far higher.
The promotional name and timing immediately triggered widespread public fury across South Korea, as observers drew a direct parallel between the ‘tank’ branding and the military tanks deployed to crush the pro-democracy movement. What followed was a sharp drop in consumer sales, a nationwide call for a public boycott, and the immediate dismissal of Starbucks Korea’s chief executive, Son Jung-hyun.
During Tuesday’s press briefing, Shinsegae executive Jeon Sang-jin presented the findings of the company’s internal investigation, which uncovered a pattern of reckless prioritization of speed over due diligence that extended from the campaign’s planning through its approval process. Jeon revealed that the marketing team relied entirely on artificial intelligence to generate campaign concepts, and the team members claimed the May 18 anniversary never registered as a problematic date during the ideation phase. ‘Those involved denied any intentional wrongdoing,’ Jeon stated, adding that the team only recognized the harm of the campaign after widespread public backlash erupted.
The investigation also uncovered extreme negligence during the approval stage: of the seven senior officials required to sign off on the campaign, multiple approved the proposal as a routine administrative task without even opening the email attachment containing the campaign design and full details. Additionally, the mandatory legal team review that had been standard for all previous marketing campaigns was completely skipped for this promotion.
Three of the five marketing team members working on the campaign have refused to surrender their mobile devices for independent forensic investigation, citing personal privacy rights, leaving open questions about whether the team intentionally moved forward with the AI-generated concept despite any implicit red flags. The internal probe confirmed the company has failed to build sufficient social and historical sensitivity across its teams, a systemic shortcoming that goes far beyond individual employee error.
South Korean President Lee Jae Myung has already publicly condemned the campaign as ‘inhumane and disgraceful’, and local law enforcement has launched a separate criminal investigation. If investigators find evidence that the campaign was intentionally created to mock or trivialize the Gwangju Uprising, those responsible could face criminal charges in addition to termination from the company.
Shinsegae Group Chairman Chung Yong-jin opened the press conference with a deep public bow, issuing a direct apology to the bereaved families of Gwangju uprising victims and accepting full accountability for the incident. ‘I will make no excuses. I take full responsibility for this matter,’ Chung said, before declining to take questions from assembled reporters.
