The 'Name Change' Craze and the Psychology of Saju Myeongrihak: Korean Names and Destiny

Published on February 25, 2026

Korea is one of the countries with a very active 'name change' (改名) application rate worldwide. What was once negatively perceived, name change has now become a personal choice and right. The backdrop of this unique 'name change craze' is a complex interplay of the deep-rooted belief in Saju Myeongrihak (四柱命理學) that names profoundly influence one's destiny, and the modern individual's psychology of seeking to redefine their own identity.

Names are Destiny: A Saju Myeongrihak Approach

In Korea's traditional Saju Myeongrihak, names (naming) are believed to greatly influence a person's destiny and fortune. If Saju (birth year, month, day, and hour) is one's innate destiny, then names are considered an important element that can complement and improve destiny later in life. Experts, known as 'name givers,' create names according to various criteria, such as supplementing the Five Elements (五行: wood, fire, earth, metal, water) lacking in one's Saju, or considering pronunciation and stroke count. If a name does not align with one's Saju or if a particular pronunciation is deemed inauspicious, the desire to improve one's destiny through a name change is activated.

Modern People's Desire to Redefine Identity

While name changes in the past were primarily a passive choice to avoid difficult situations, modern name changes have evolved into a process of active self-identity exploration and redefinition. This is connected to the modern individual's psychology of proactively shaping their own life, beyond merely avoiding misfortune.

Sociocultural Background of High Name Change Rate

Korea's high name change rate is not simply due to superstitious beliefs. There are complex socio-cultural backgrounds behind it.

Korea's 'name change craze' is a complex cultural phenomenon where traditional Saju Myeongrihak beliefs, modern individuals' desire to explore their self-identity, and legal and social changes are intertwined. Beyond a mere appellation, a name serves as a crucial medium for projecting and reconstructing an individual's life and destiny, prompting a continuous exploration of Korean identity.
