A Tradition Older Than Modern Corporations
Somewhere right now, someone is staring at a decision that can't be undone — sign the lease, take the offer, walk away — with no one they trust enough to ask. Historically, that's exactly the position a saju master was called in to help with, and not only for kings.
Long before Saju had anything to do with corporate boardrooms, it was the tool Korea's own rulers relied on. Kings of the Joseon Dynasty (1392–1897) consulted saju masters before major decisions of state: military campaigns, royal marriages, succession timing, and governance strategy. The system was never treated as folk superstition at the top of Korean society — it was part of how power was exercised responsibly.
That history matters for understanding why the practice carried over so naturally into the modern business world. When a decision carries enough weight and irreversibility, seeking a second, structured perspective on timing isn't seen as a departure from rational leadership — historically, it was rational leadership.
The Best-Documented Case: Samsung's Founder
The most widely reported example in modern Korean business is Lee Byung-chul, the founder of the Samsung Group. Multiple Korean and international business publications have reported that Lee regularly consulted the saju master Park Jae-hyun before key business decisions — a detail frequently cited as an example of how seriously fortune-telling and saju consultation have historically been taken by some of Korea's most consequential business figures.
Source note
This account is widely reported in Korean business journalism (see The Korea Times' coverage of fortune tellers and business tycoons) rather than a single primary confirmation from Samsung itself. It's treated in Korean media as established business history, not rumor — but it's worth citing as "widely reported" rather than as a formal company statement.
Picture the founder of what would become the largest company in Korea, before any of that was guaranteed, still asking someone else to help him read the timing. If the stakes were that high and he still wanted a second read, it's a reasonable thing to want for far smaller decisions too.
What Modern Executives Actually Use It For
The pattern isn't limited to one historical figure. Korean business reporting has repeatedly described a broader, ongoing practice among executives and corporations of consulting geomancers and saju masters — not for mystical guarantees, but as one more input into decisions that are already high-stakes and hard to reverse:
- Hiring decisions for key leadership roles
- Timing for entering a new market or launching a new business line
- Deciding when to cut costs or restructure
- Choosing auspicious dates for major announcements, product launches, or even presidential inaugurations
The underlying reasoning cited across this coverage is consistent: leaders making decisions of unusual complexity and consequence — the kind an average employee never has to make — sometimes seek an additional structured framework for thinking through timing and risk, beyond spreadsheets and market data alone.
Whether or not you run a company, your own Day Master reveals the same kind of elemental timing pattern executives have consulted for decades.

It's easy to dismiss this as just powerful people indulging in mysticism. But the more useful frame is that Saju, at its core, is a structured system for thinking about cycles: when momentum favors action, when a period calls for consolidation instead, and which kinds of people or timing tend to complement your own pattern. Executives making irreversible, high-stakes calls have historically valued exactly that kind of structured framework — regardless of what else they believe about fate.
The decision you're staring at right now doesn't need to wait for a board meeting or a Samsung-sized budget. The same framework starts with the same single piece of information every executive's reading starts from. It's not a coincidence. It's Saju.
