From the bustling streets of Seoul to the serene countryside, South Korea holds a myriad of beliefs that have been interwoven with its history for centuries. While modernization has surged, the heartbeat of age-old superstitions still echoes in the daily lives of many Koreans. Whether it’s the cautious avoidance of number four, reminiscent of a shared East Asian trepidation, or the playful taboo of gifting shoes, these beliefs provide a fascinating glimpse into the nation’s collective psyche.
South Korea’s superstitions don’t just exist as lingering tales of yore; they often blend seamlessly with contemporary culture. Some, like the famous ‘fan death’ theory, have even spurred technological adaptations, such as the introduction of timers in electric fans. Others, like specific dream interpretations, have created delightful traditions, prompting people to try their luck with lottery tickets after a particularly auspicious dream.
Yet, what makes these superstitions genuinely captivating is their ability to reveal aspects of the Korean mindset, values, and shared cultural experiences. Let’s dive in to 10 common superstitions in South Korea!

Fan Death (선풍기 사망설)
- Origin: The origins of the fan death superstition are not entirely clear. Some speculate that it arose during the 1970s energy crisis to encourage people to conserve electricity, while others believe it’s an explanation for unexpected deaths during sleep. The idea is that using a fan in a closed room might either cause suffocation or hypothermia.
- Modern Perception: While many modern Koreans, especially the younger generation, consider the idea of fan death to be a myth, it’s still common to find fans sold in Korea that come with a timer function. This timer is designed to turn the fan off after a set number of hours to prevent “fan death.”

Whistling at Night
- Origin: Whistling might have been considered a way of calling or inviting unwanted spirits or supernatural entities in the past. In traditional Korean beliefs, night was when spirits and ghosts were most active.
- Modern Perception: While it’s less adhered to in urban areas, some older generations might still advise against whistling after dark.
Shaking Your Leg
- Origin: In the past, showing restless behavior or constant movement, like shaking one’s leg, could have been considered disrespectful or a sign of impatience. The connection to losing fortune might be symbolic of losing stability.
- Modern Perception: It’s still common for older individuals to advise younger ones not to shake their legs, though it’s more seen as a cultural etiquette than a genuine belief in bad luck.
Number 4 (사)
- Origin: The fear of the number four is shared with other East Asian cultures, like China and Japan, due to its phonetic similarity to the word for death.
- Modern Perception: Many buildings, especially older ones, in Korea skip the fourth floor (similar to how some Western buildings skip the 13th floor). However, as society modernizes, newer buildings often include the fourth floor without any alterations.

Dreams
- Origin: Dream interpretation has ancient roots in Korean culture. Specific dreams, like those of pigs, are deemed auspicious and linked to wealth and prosperity.
- Modern Perception: While not everyone might rush to buy a lottery ticket after a particular dream, sharing dreams and discussing their meanings remains a popular cultural activity.
Moving Day
- Origin: The importance of choosing an auspicious day for significant events, like moving, has roots in traditional Korean shamanism and geomancy (feng shui). It was believed that settling on a bad day could disrupt the harmony of the household.
- Modern Perception: Some people still consult the lunar calendar or geomancy experts before choosing a moving day, especially when moving into a new house.

First Birthday (doljanchi)
- Origin: The ritual stems from a time when childhood mortality rates were high, and reaching the first birthday was a significant milestone. The items chosen in the ritual represent various professions or life paths.
- Modern Perception: ‘Doljanchi’ remains a significant celebration, though more for cultural and familial reasons than genuine belief in the ritual’s predictive powers.
Red Ink
- Origin: In historical documents, the names of deceased individuals were sometimes written in red, making it taboo to write the living’s names in the same color.
- Modern Perception: While the practice of writing in red ink isn’t as strictly tabooed as before, many Koreans will still avoid writing a person’s name in red, especially the older generation.
Gifts of Shoes
- Origin: Shoes are made for walking, so gifting them might symbolize walking away from the giver.
- Modern Perception: While this superstition isn’t universally adhered to, it’s common for people to “sell” shoes for a token amount, like one Korean won, to circumvent the superstition.

Eating Seafood Before an Exam
- Origin: The slippery nature of seafood symbolizes knowledge or information “slipping away.”
- Modern Perception: While it’s more of a playful belief, some students might still avoid seafood dishes right before important exams.
In the vast landscape of human beliefs, Korea’s unique set of superstitions offers a window into how tradition, nature, and modern life intertwine on the peninsula. They serve as gentle reminders of the past, nodding to ancient wisdoms, while also evolving and finding relevance in contemporary times. As times change, some of these beliefs might fade, while others will adapt and continue. But for now, they remain intriguing threads connecting the old with the new, showcasing the ever-evolving narrative of Korean culture.
