Saju Naming
사주 작명 (四柱 作名)
A naming method based on the Four Pillars of Destiny (saju), which analyzes the year, month, day, and hour of birth to determine auspicious name characters.
Saju naming (사주 작명) is one of the most widely practiced traditional naming methods in Korea, rooted in the Four Pillars of Destiny (사주팔자/四柱八字) system. The 'four pillars' refer to the year, month, day, and hour of a person's birth, each expressed as a pair of Heavenly Stems (천간/天干) and Earthly Branches (지지/地支). Together, these eight characters (팔자) form a cosmological profile that is believed to reveal a person's innate tendencies, strengths, weaknesses, and life trajectory.
The Naming Process
In saju naming, a consultant first constructs the child's saju chart based on the exact date and time of birth using the traditional Korean-Chinese calendar system. The chart is then analyzed to identify the balance of yin and yang energies and the distribution of the five elements (ohaeng). Based on this analysis, the consultant identifies which elements need to be strengthened through the name. They then select hanja characters that not only carry auspicious meanings but also contain the appropriate elemental radicals. The total stroke count, phonetic flow, and visual aesthetics are also factored into the final recommendation, which typically includes three to five name options for the parents to choose from.
Prevalence and Cost
Saju naming remains remarkably popular in contemporary South Korea. According to industry estimates, over 50% of Korean parents consult a saju naming professional when naming their newborn. The cost of a professional saju naming consultation ranges from 100,000 to 500,000 Korean won (approximately $75 to $375 USD), with well-known consultants charging significantly more. Online saju naming services have also proliferated, offering automated analysis at lower price points. Critics argue that the practice has no empirical basis, but proponents view it as a meaningful cultural tradition that connects the child to Korea's philosophical heritage and provides parents with a structured, thoughtful approach to the important decision of naming their child.
