You already know your star type. You clicked the calculator, found out you are a Venus-Plus or a Jupiter-Minus, and read the personality profile. But personality profiles are the shallow end of the pool. To actually use Rokusei Senjutsu—the famously ruthless system that dominated Japanese media for decades—you have to read the full chart.
If you are coming from Western astrology, you must unlearn everything. A Six Star Astrology chart is not a mood board of planetary transits; it is a mathematical matrix. It runs on four distinct layers: the destiny number (seimeisu), the plus/minus polarity, the 12-year fortune cycle, and the dreaded Daisakkai. If you only look at your base star, you are driving blind.
Before we begin, if you have not calculated your base star yet, find your star type first. If you need a refresher on what Six Star Astrology is historically, review the basics. Otherwise, here is how to actually read the data.
Layer 1: The Destiny Number (Seimeisu)
The foundation of your chart is the destiny number, or seimeisu. This is a value from 1 to 60 calculated from your exact birth date using the Chinese sexagenary cycle. This number does not just assign your star; it dictates your precise coordinate in the system's architecture.
The math is rigid. The 60 numbers are divided into six planetary types:
- Saturn (1–10): The idealistic earth element, representing people who are deeply principled but prone to rigid thinking.
- Venus (11–20): The free-spirited metal element, constantly seeking motion, aesthetics, and social connection.
- Mars (21–30): The mysterious fire element, driven by intuition and often misunderstood by their peers.
- Uranus (31–40): The rational, stubborn wood element, representing people who prioritize logic over emotion.
- Jupiter (41–50): The methodical, aggressive earth element, known for slow, deliberate accumulation of wealth and status.
- Mercury (51–60): The independent water element, fiercely self-reliant and highly pragmatic.
If your destiny number falls between 11 and 20, you are a Venus type. If it lands between 51 and 60, you are a Mercury type. This base star determines your fundamental operating system. Venus is wired for constant motion; Mercury is wired for self-reliance.
But stopping here is the most common misreading of the system. Your base star is just the vehicle; it does not tell you where the vehicle is currently parked. To find that, you need the second layer.
Layer 2: The Polarity (+/-)
Every star type is split into two parallel tracks based on polarity. You are not just a Mars; you are a Mars-Plus (+) or a Mars-Minus (-). This polarity is determined by the Chinese zodiac animal of your birth year.
The rule is straightforward:
- Odd years—the years of the Rat, Tiger, Dragon, Horse, Monkey, and Dog—carry a positive (+) polarity.
- Even years—Ox, Rabbit, Snake, Sheep, Rooster, Boar—are assigned a negative (-) polarity.
Why does this matter? Because polarity dictates your timeline. A Mars-Plus and a Mars-Minus share the exact same mysterious, intuitive personality traits, but their internal clocks are entirely out of sync. When the Plus polarity is experiencing a summer of success, the Minus polarity might be freezing in the winter of their cycle. Polarity is the gear that locks your destiny number into the calendar year. Without knowing your polarity, you literally cannot read the 12-year cycle. You might think you are in a year of "Success" when you are actually walking straight into a year of "Decline."
Layer 3: The 12-Year Fortune Cycle
This is the engine of the chart. Rokusei Senjutsu does not care about where actual planets are in the sky today; it cares about where your specific polarity sits on a fixed 12-step dial.
Every type moves through a 12-year cycle, advancing one phase every calendar year (starting January 1st, not on your birthday). Let's break down the phases in detail:
- Seed (Tane): The beginning of a new 12-year era. This is the time to initiate, study, and plant the ideas that will sustain you for the next decade.
- Bud (Ryokusei): Early growth. Your initiatives are taking root, but they are vulnerable. Nurture them without forcing outcomes.
- Flower (Risshi): Establishment. Your efforts become visible to the outside world. A strong year for career advancement.
- Warning (Kenjaku): A minor physical or mental health dip. The universe forces you to rest. Do not ignore physical symptoms this year.
- Success (Zaiki): Financial and professional harvest. The seeds you planted four years ago finally pay off.
- Great Success (Kouki): The absolute peak of the 12-year cycle. Your energy is unmatched, and bold moves are heavily rewarded.
- Shadow (In): The first year of the Daisakkai. Energy begins to rot. Things that used to work suddenly face inexplicable friction.
- Halt (Teishi): The second year of the Daisakkai. Total stagnation. Your judgment is compromised, and major life changes will likely fail.
- Decline (Gensei): The final year of the Daisakkai. A period of loss and clearing out. Let go of what is breaking; do not try to fix it.
