Starbucks Korea will temporarily close all its stores on June 22, 2026, for mandatory employee training on Korean history and social sensitivity [1].

The move follows intense public outrage over a "Tank Day" marketing campaign. The promotion referenced the 1980 Gwangju Uprising, a period of civil unrest and a military crackdown that resulted in the deaths of at least 165 civilians [6].

Company officials said the closure will affect more than 2,000 outlets across South Korea [1]. The training session will include the company chairman and all employees. The stores will be shut for a period ranging from three hours [2] to half a day, or approximately four to five hours [3], on the morning of June 22 [1].

Critics said the brand's marketing was insensitive to the trauma associated with the Gwangju Uprising. The military's actions in 1980 remain a deeply sensitive subject in South Korean society, marking a pivotal moment in the country's struggle for democratization.

The decision to halt operations for training is expected to have a significant financial impact. Estimates suggest the company will face a sales loss of 2.1 billion won, which is approximately $1.4 million [4].

This widespread closure is a rare corporate admission of cultural insensitivity in the region. By shutting down every location, the company aims to signal a systemic commitment to correcting the lack of historical awareness that led to the promotion.

This incident highlights the volatility of corporate marketing in South Korea, where historical trauma and national identity are closely guarded. The decision to implement a mandatory, company-wide shutdown suggests that the brand viewed the backlash not as a PR hurdle, but as a fundamental failure in cultural competency. For multinational corporations, this underscores the necessity of local historical vetting to avoid alienating consumers in markets with complex political legacies.
