Starbucks Korea  (SBUX) will shut its outlets nationwide for three hours on June 24 to put staff through historical awareness training, the company announced on June 16, BBC reports. The decision follows intense public outrage over a promotional campaign that evoked a deadly 1980 military crackdown on pro-democracy protesters.

This corporate crisis highlights the high stakes for foreign brands navigating historical memory in South Korea, where tone-deaf marketing can trigger swift financial pain. Starbucks South Korea sales fell by $6.5mn after the marketing blunder, illustrating the immediate economic impact of consumer boycotts.  

The coffee chain faced immediate boycott calls after launching its Tank Day reusable cup promotion on the anniversary of the Gwangju Uprising. At least 165 civilians died during the military crackdown, though activists say the real figure is much higher.

Shinsegae Group, which operates the franchise under a licensing agreement, sacked the Starbucks Korea chief executive on the day the scandal broke. Group Chairman Chung Yong-jin will also attend the training. Outlets across the country will close at 15:00 local time (06:00 GMT) on June 17 and will not reopen until the following day. All employees will watch videos to boost historical awareness and social sensitivity. This marks the first nationwide early closure for Starbucks Korea since its local debut in 1999.

The Tank Day campaign promoted large drink tumblers designed for spacious volume. Starbucks Korea initially stated the merchandise was part of a regular rollout running from May 15 to May 26. The company later issued an apology for causing inconvenience and concern to customers.

The political and economic blowback was immediate. President Lee Jae Myung condemned the promotion on social media, calling it inhumane and disgraceful conduct. Protesters picketed outside retail locations, and outlets suffered a significant drop in retail turnover following widespread calls for a consumer boycott.

The Gwangju Uprising remains a sensitive flashpoint. The event set the country on its path toward democracy, inspiring the June 1987 movement that finally toppled Chun's regime.

Critics claim the Starbucks campaign also inadvertently referenced the 1987 protests. Promotional material used the Korean phrase "tak on the table!", mimicking the sound of slamming an object. The word "tak" became infamous in 1987 when police used it to explain away the torture and death of a student activist in custody. Shinsegae Group noted that marketers chose the slogan based on suggestions from an artificial intelligence tool.

Chun's dictatorship ended in 1988. Courts convicted him of treason and corruption in 1996, though he later received a presidential pardon. He died in 2021 aged 90. The state officially apologised for the military's use of sexual violence in 2018. Chun's grandson, Chun Woo-won, also offered a public apology to survivors, branding his grandfather a sinner and slaughterer.
