What the chart says

Koichi, according to the stars

Core essence

Koichi is warm the way the sun is warm: not trying, just doing it. The core of Koichi is a big open heart and a need to be seen loving with it. They are generous with praise, with time, with the spotlight when they trust you, and they will remember every kindness you paid them for years. Loyal to a fault, and glad of the fault.

The vibe

Underneath, Koichi is all feeling, tide in and tide out. The Moon in Cancer means moods are weather, real and passing, and memory is long: they keep every kindness and, quietly, every slight. What Koichi needs to feel safe is a soft place to land that is not going anywhere. Give them that and they give you everything.

How Koichi wants to be loved

Koichi wants to be loved attentively. Venus in Virgo shows love through service, the fixed thing, the remembered appointment, and wants to be loved the same way: notice what they did. Big words matter less than the follow-through. Be reliable with Koichi and they will quietly make your whole life run better.

How Koichi creates

How Koichi makes things happen: they hold the flame steady. A Yin Fire day master is the candle, the lamp, the light that is close and personal rather than blazing. Koichi creates intimacy, one room, one conversation, one person made to feel seen. Moody when the fuel runs low, magnetic when it does not.

Instinct

Instinct: Koichi is warm and generous, a Pig year, and their gut reaction is to trust. Big-hearted, fun, sincere, a lover of good things, and deserving of people who are as honest as they are. The Earth year grounds it: practical, patient, someone people lean on.

Purpose

Purpose: Life Path 8 is the powerhouse. Koichi is here to build something big and run it well: money, influence, a body of work with their name on it. Ambitious, capable, generous when winning, and learning that power is for lifting people.

Triggers

Triggers: sloppiness, and being told they are overthinking it. Mars in Virgo means Koichi channels energy into fixing, sorting, getting it right, and gets sharp when others do not care. The critic turns inward first. Give them a problem worth solving and watch them come alive.

If you only read one paragraph

Leo Sun

The room rearranges itself.

Koichi Tanaka's Sun was in Leo for the whole of August 3, 1959, so no birth time is needed to settle it. Traditional Leo readings associate the sign with warmth, visibility and generosity: a natural claim on attention and a habit of handing it back as encouragement. Astrologers describe it as the fixed fire sign, ruled by the Sun. The corresponding tension is pride, with the classical caution that the need to be seen can crowd out people who would rather not be.

Earth Pig

Trusts easily. Rarely regrets it.

Koichi Tanaka was born on August 3, 1959, which falls in a Earth Pig year of the Chinese calendar. Traditional Pig readings emphasise generosity, sincerity and an appetite for the good things, shared. The Chinese almanacs describe the Pig as the most open-handed sign in the cycle, trusting and hard to anger. The corresponding caution in the tradition is naivety, and a difficulty believing that anyone would take advantage of that trust.

Life Path 8

Wants it all. Gets most.

Koichi Tanaka's birth date, August 3, 1959, reduces to Life Path 8 under the numerology method AsterNym uses. Traditional Life Path 8 readings associate the number with ambition, authority and material results: turning sustained effort into visible achievement. Numerologists describe it as the path of the executive. The corresponding tension is control, with the caution that a number this good at managing outcomes can begin managing people the same way.

Reference chart · birth time unknown

No documented birth time exists for Koichi Tanaka, so the positions below are checked across the whole birth date, not fixed at noon. The Moon ranges from 16° to 28° Cancer depending on the hour. The wheel's houses are a solar chart, counted from the Sun's sign, because the Ascendant needs a time.

Aspects across every possible birth time

Stable aspects hold for any birth hour. Possible ones depend on the hour, so their orb is a range rather than a number. Orb policy western_v1.

Koichi’s Chiron, Ceres, Eros, Hygiea and Lilith

Four minor bodies and the mean lunar apogee, placed in the same tropical zodiac as the planets above. None of these feed the chart signature, the rarity score or any ranking on this site: they are listed for readers who use them. Chiron, Ceres, Eros and Hygiea positions come from JPL Horizons; Black Moon Lilith is the mean apogee, the point most published Lilith tables use. The readings are the modern tradition’s, not AsterNym’s. Without a birth time the degree is the noon value and the day's movement is shown alongside it.

  • ⚷ Chiron ℞Aquarius 25°55′ (moves 0.05° over the day)

    centaur (2060) · the wound and what is learnt from it

    Chiron in Aquarius is read as a wound around fitting in. The tradition has Koichi making a place among outsiders and keeping the door open for the next one.

  • ⚳ CeresScorpio 17°42′ (moves 0.18° over the day)

    dwarf planet (1) · how a person nurtures and wants to be nurtured

    Ceres in Scorpio is read as nurture that goes all in: loyalty, intensity, a care that does not do halfway. Koichi is read as fierce about the people counted as theirs.

  • ♡ ErosLibra 6°52′ (moves 0.76° over the day)

    near-Earth asteroid (433) · what draws them and how they desire

    Eros in Libra is read as desire for the beautiful and the mutual. Koichi is read as someone who wants the pairing itself as much as the person.

  • ⚕ HygieaCancer 26°01′ (moves 0.34° over the day)

    main-belt asteroid (10) · health, routine and what keeps them well

    Hygiea in Cancer is read as health tied to home, mood and belonging. Koichi is read as someone who does not thrive far from a base.

  • ⚸ Black Moon LilithTaurus 28°53′ (moves 0.11° over the day)

    mean lunar apogee · the part that refuses to be tamed

    Black Moon Lilith in Taurus is read as an unbargained appetite: for pleasure, for ownership, for a body that answers to nobody. Koichi is read as immovable on those points.

Aspects to the asteroids and Lilith

Major aspects only, at a tight 3° orb. The Moon is left out because its position moves 13° across an untimed day.

  • Ceres square Uranus 1.4°
  • Ceres sextile Venus 2.7°

Method: JPL Horizons heliocentric vectors, 1700–2100, cubic Hermite interpolation; geocentric, true ecliptic of date, tropical; geometric (no light-time or aberration); Lilith = mean lunar apogee (Chapront/Meeus mean perigee + 180°).

Koichi’s dominant planets

Scored from rulerships, dispositors and aspect count. Without a birth time there is no Ascendant or house to score, and the Moon's sign is left out where it could change with the hour.

  1. 1. ☉ Sun10 pts

    rules the Sun sign, Leo; in its own sign, Leo; disposes Mercury, Uranus; 3 major aspects

  2. 2. ☿ Mercury5 pts

    disposes Venus, Mars, Pluto; 2 major aspects

  3. 3. ♇ Pluto5 pts

    disposes Jupiter, Neptune; 3 major aspects

A Sun-led chart is read as identity out front: Koichi is read as someone whose sense of self organises everything else.

How the score is built
  • Rules the Sun sign, Moon sign or Ascendant sign: 3 points each (traditional co-rulers of Scorpio, Aquarius and Pisces score half).
  • Sits in a sign it rules: 2 points.
  • Disposes another planet (that planet sits in a sign it rules): 1 point each.
  • Angular: 2 points in the first or tenth house, 1 point in the fourth or seventh (timed births only).
  • Every major aspect it makes: 1 point.

Dominance scoring is an AsterNym method. Other sites weight differently and can name a different leader for the same chart.

Configurations in Koichi’s chart

Closed shapes among the ten planets under the site’s one aspect-orb policy. The Moon is excluded without a birth time, so a shape that needs it is not claimed.

  • stellium, the shape it makesStellium in Leo · Sun, Mercury, UranusThree or more planets in one sign (four, or three with a luminary, by AsterNym's count): a concentration astrologers read as that sign's themes dominating the chart.

semi-sextile 30° (orb 2°), semi-square 45° (orb 2°), quintile 72° (orb 1.5°), sesquiquadrate 135° (orb 2°), biquintile 144° (orb 1.5°), quincunx 150° (orb 2.5°). Pairs already in a major aspect are not repeated. Moon excluded without a birth time.

Houses need a birth time. None is documented for Koichi Tanaka, so no house placements are claimed for the planets or the minor bodies above.

No birth time is on public record for Koichi Tanaka, so this chart has three pillars rather than four. The hour pillar, the rising sign and the birth-sky star all need a time, and we would rather leave them out than invent one.

Where this data comes from

Koichi’s birth date and birthplace come from Wikidata Q110963, released under CC0, as do the occupations, works, teams and awards in the biography above. No documented birth time is available, so this chart is rated X on the Rodden scale, the astrological convention for how well evidenced a birth time is. Time-dependent results use a clearly labelled reference time and should not be read as their exact birth chart. Entries are matched to Wikidata by entity id rather than by name, kept only at day precision, and dropped where sources disagree on the date.
