Yes, the number 4 is considered unlucky in Korea.
The reason for this superstition stems from the fact that the Sino-Korean word for "four" (사, pronounced sa) sounds very similar to the Sino-Korean word for "death" (사, also pronounced sa). This phonetic similarity has led to a widespread association of the number 4 with misfortune and death.
Manifestations of the Superstition:
- Building Design: In many buildings, particularly residential ones like apartment complexes, the fourth floor might be labeled with the letter "F" instead of the number 4.
- Elevators: Elevators often omit the number 4.
- Real Estate: The fourth floor of an apartment building is often perceived as less desirable, and consequently, it may be cheaper to purchase or rent.
- General Avoidance: While not always strictly adhered to, some individuals may consciously avoid using the number 4 in significant aspects of their lives where possible.
While the level of adherence to this belief varies among individuals, it's a prevalent cultural superstition in Korea, particularly noticeable in architectural design and property values.
