Ever wondered why some celebrities methodically build billion-dollar empires while others burn bright, disrupt industries, and spontaneously self-destruct? In Japan, the entertainment industry’s open secret for decoding these unpredictable trajectories is Six Star Astrology (Rokusei Senjutsu). Conceived by the formidable Kazuko Hosoki who created the system in the 1980s, this astrological framework divides humanity into six distinct planetary types—Saturn, Venus, Mars, Uranus, Jupiter, and Mercury.
Governed by a strict 12-year cycle of fortune and stagnation, the system dictates that every individual must pass through the infamous Daisakkai (the Great Killing World)—a brutal three-year winter where karma comes to collect. For decades, elite PR agencies and talent managers secretly consulted these charts before booking major stadium tours, greenlighting blockbuster movies, or approving high-profile celebrity marriages.
Today, the system remains a massive cultural touchstone. Fans and critics alike rush to calculate any birth date's type to decode the hidden drives of global A-listers. It provides a surprisingly accurate blueprint for how different flavors of ambition manifest on the world stage. Here is how the biggest names in sports, music, and business map onto the six stars—and what their planetary alignment reveals about their ultimate destinies.
Jupiter (Mokuseijin): The Unstoppable Grinders
Jupiter types (Mokuseijin) are the quintessential slow and steady builders of the zodiac. They are traditionalists, fiercely methodical, and possess an almost frightening capacity for hard work. While other stars might seek instant gratification or viral fame, Jupiters play the long game. They are notoriously slow starters in life, often facing immense hurdles in their early years, but once they find their footing, their momentum becomes an unstoppable juggernaut.
Take Taylor Swift, born December 13, 1989. As a Jupiter (-), Swift embodies this relentless, calculating work ethic. From meticulously re-recording her entire back catalog to reclaim her masters, to executing the record-breaking, multi-year Eras Tour, she leaves absolutely nothing to chance. If you want a deep dive into what each type means, Jupiters are defined by this exact brand of resilience.
Fellow Jupiter (-) Tiger Woods (born December 30, 1975) showcased the same grinding, obsessive dedication to mastering his sport. Jupiters rarely stumble into fame by accident. They engineer their empires brick by brick, relying on stamina rather than sheer luck. When a Jupiter type faces a scandal or a career setback, they don't panic—they simply put their heads down, outwork their critics, and wait for the wheel to turn back in their favor.
Mars (Kaseijin): The Eccentric Visionaries
If Jupiters are the steady, predictable builders, Mars types (Kaseijin) are the enigmatic aliens who rewrite the rules of reality. Highly professional, deeply eccentric, and fiercely independent, Martians are my-pace visionaries. They often struggle with conventional emotional expression and can seem incredibly aloof, but they excel when hyper-focused on a singular, seemingly impossible goal.
Look no further than Shohei Ohtani, born July 5, 1994. As a Mars (+), Ohtani’s unprecedented two-way dominance in Major League Baseball stems from this exact Martian singularity. He exhibits a total, monastic devotion to his craft above all earthly distractions. He doesn't care about the traditional limits of the sport; he operates in a universe of one.
Elon Musk, another widely cited Mars type, exhibits the shadow side of this planetary alignment. Brilliant, industry-disrupting, yet volatile and deeply mysterious to outsiders, Musk's erratic acquisition of platforms like X (formerly Twitter) is a classic Martian move. Martians do not care about the status quo or public opinion. They are here to build their own universe, and they expect everyone else to simply adapt to their gravity.
Venus (Kinseijin): The Trendsetting Free Spirits
Venus types (Kinseijin) are the glittering socialites and the eternal free spirits of the Six Star system. Action-oriented, flashy, and intensely restless, they operate entirely on intuition, charm, and an insatiable desire for the spotlight. A Venusian cannot stand being tied down by heavy tradition, rigid schedules, or emotional baggage. They are the ultimate trendsetters, pop idols, and fashion icons who intuitively understand what the zeitgeist demands before the public even knows it.
Because they are so forward-looking and adaptable, Venus types bounce back from minor failures with astonishing speed. They are the celebrities who can survive a messy public divorce and immediately launch a bestselling lifestyle brand. However, their Achilles' heel is a chronic lack of deep, long-term planning.
When a Venus celebrity hits their Daisakkai (the dreaded 3-year period of universal stagnation), their usual strategy of just "winging it" spectacularly backfires. Without the anchor of a solid, long-term strategy, their impulsive nature leads to highly publicized PR disasters. Yet, true to their star, once the storm passes, they dust themselves off and charm their way right back into the public's good graces.
Uranus (Tennouseijin): The Charismatic Networkers
Where Mars wants to be left alone in a laboratory, Uranus (Tennouseijin) absolutely needs a crowded room. Uranus types are the ultimate networkers—warm, communicative, and deeply family-oriented. They thrive in group dynamics and possess a natural, undeniable magnetism that draws fierce loyalty from those around them.
