Real Korean Superstitions Explained: A Cultural Guide for Travelers

 

South Korea is known for its advanced technology and fast-paced lifestyle, but traditional beliefs still quietly influence daily life. While not everyone follows them strictly, many Korean superstitions are widely known and culturally rooted. Understanding them offers valuable insight into Korean history, values, and social etiquette.

1. Writing a Name in Red Ink

Writing someone’s name in red ink is traditionally associated with death. In the past, the names of the deceased were written in red in official records to ward off evil spirits. Even today, writing a living person’s name in red is considered highly inappropriate.

 

2. The Number 4 Brings Bad Luck

The number 4 is avoided in many buildings because it sounds like the word for “death” (사, sa) in Korean. You may notice elevators skipping the fourth floor or labeling it as “F” instead. This belief is still very common.

 

3. Don’t Cut Your Nails at Night

This superstition dates back to a time when lighting was poor and nail clippings were believed to attract bad spirits. While most people no longer believe this literally, the saying is still well known.

 

4. Sleeping with a Fan On Can Be Dangerous

Known as “fan death,” this belief suggests that sleeping in a closed room with a fan on can be harmful or even fatal. Although scientifically disproven, the superstition is famous enough that fans in Korea often come with automatic timers.

 

5. Opening an Umbrella Indoors Brings Bad Luck

Opening an umbrella inside the house is believed to invite misfortune. This superstition exists in several cultures, but in Korea it is often taught from childhood as a matter of manners and caution.

 

6. Shaking Your Legs Means Losing Wealth

Shaking your legs while sitting is considered impolite and is believed to “shake away” fortune or money. Older generations especially view this habit negatively.

 

7. Shoes Should Not Face the Door

Shoes pointed directly toward the entrance are traditionally associated with funerals and departure from the home. Placing shoes neatly, facing inward, shows respect and good energy.

 

 

8. Whistling at Night Attracts Bad Spirits

Whistling after dark is believed to attract ghosts or unwanted spirits. While younger people may joke about it, the superstition remains well known.

 

9. Giving Shoes to a Partner Means They Will Leave

Giving shoes as a gift is believed to symbolize someone “walking away” from you. To avoid bad luck, some people symbolically give a small coin in return, turning the gift into a “purchase.”

 

Do Koreans Still Believe in These Superstitions?

Most modern Koreans do not strictly follow all these beliefs, especially younger generations. However, they remain culturally significant and are often respected out of politeness, habit, or family tradition.
