Jiro Horikoshi birth chart is shown with zodiac signs and aspects. Because the birth time is unknown, Arcadia does not use houses, Rising sign, or angular dominants as the main basis of interpretation.
Jiro Horikoshi's chart rests first on the stable factors: Sun in Gemini and Moon in Taurus. Without a reliable time, signs and aspects are stronger than the Rising sign or houses.
Chart detail:
Mercury trine Saturn (orb 0.8°) gives a central dynamic in this reading. The orb is extremely tight; this aspect is one of the chart's strongest signals.
In plain terms, this aspect positively structures intellect, method, and speech.
The birth time is not known with certainty, so the Rising sign and houses are less reliable. Signs and exact aspects give the safer reading base.

Signs Mercury in Gemini
Aspects Venus opposite Saturn (orb 5.9°) · Mars square Neptune (orb 4°) · Jupiter square Pluto (orb 3.1°)
This section gives a concrete reading thread. It highlights the most visible signatures, then the tabs keep each placement separate instead of mixing everything together.
Important: Unknown birth time: the Rising sign, houses, and angular dominants are too time-sensitive to anchor the interpretation. The Moon remains useful, but its exact aspects can shift during the day: tight non-Moon aspects are more reliable when they exist.
Start here: a short reading that shows what hooks, what helps, what pushes back, and where it becomes concrete.
Sun in Gemini · Moon in Taurus
First hook: this is where the chart often becomes recognizable in real life. Sun in Gemini: identity and direction move through curiosity, language, movement, and mental adaptation; Moon in Taurus: emotional safety looks for nature, good food, physical sensuality, roots, resources, and perseverance. Because the birth time is missing, reliable aspects should carry the next step before houses or angles.
Dominants unavailable without reliable birth time
Angular dominants depend on birth time. Without a reliable hour, do not use them as primary evidence.
Harmonious triangle: Saturn, Mercury, and Mars
This is the easiest door into the chart: it shows what tends to cooperate naturally.
This pattern describes what comes more easily. Houses are not used here: unknown time. It connects Saturn (responsibility, limits, effort, and patience), Mercury (thinking, speech, and decisions), and Mars (action, anger, desire, and courage).
This is the clearest cooperation pattern in the chart: Mercury trine Saturn (orb 0.8°), Mars trine Saturn (orb 1.2°), and Mercury trine Mars (orb 2°). It shows where functions support each other, recover, or come naturally when used together. Because several planets are connected, the full pattern matters more than one isolated aspect.
Tension circuit: Jupiter, Uranus, Pluto, and Sun
This is the pressure line to read first: it shows where tension repeats in concrete situations.
This pattern shows where pressure builds fastest. Houses are not used here: unknown time. It connects Jupiter (growth, faith, luck, and confidence in the future), Uranus (change, freedom, rupture, and originality), Pluto (power, crisis, intensity, and deep transformation), and Sun (identity, confidence, and direction).
This is the clearest friction pattern in the chart: Jupiter square Uranus (orb 0.8°), Jupiter square Pluto (orb 3.1°), and Sun opposite Uranus (orb 6.5°). It shows where pressure, contradiction, or repeated effort concentrates. Because several planets are connected, the full pattern matters more than one isolated aspect.
Houses unavailable without reliable birth time
Houses describe domains of existence, but they depend on birth time. Without a reliable hour, signs and aspects should carry the reading.

Without a reliable birth time, the Sun, Moon, and exact aspects become the reliable base. The Rising sign, houses, and angular dominants need a reliable birth time.
The Moon can change signs during a day. Near a lunar sign change, the Moon sign remains a hypothesis.
Without a reliable hour, exact aspects and reliable repetitions can strongly nuance the starting reading.
Sun in Gemini remains a reliable combination even without a birth time. The Sun describes identity, ego, father figure, visibility, and direction, with Gemini style: curiosity, language, movement, and mental adaptation.
Concretely, the person expresses identity, ego, father figure, recognition, and personal direction through the Gemini style (curiosity, language, movement, and mental adaptation). Exact aspects and repeated patterns indicate whether this theme becomes central.
Aspect connected to this placement: Sun conjunct Neptune (orb 3.4°). Aspect effect: ties identity to image, dream, inspiration, and popularity.
Sun conjunct Neptune (orb 3.4°) brings the two planets out together. The orb is tight enough to count in the main reading.
Here, Sun in Gemini brings identity, ego, father figure, visibility, and direction with Gemini style (curiosity, language, movement, and mental adaptation); Neptune in Cancer brings imagination, image, popularity, collective moods, and inspiration with Cancer style (memory, protection, belonging, and family sensitivity).
Concrete effect: this aspect ties identity to image, dream, inspiration, and popularity.
Moon in Taurus remains a useful base without a birth time. The Moon sign is often usable, but near a Moon sign change it remains a hypothesis; the Moon describes personal dream, play, inner child, childhood imprint, mother figure, mother image, optimism, and inner rhythm, with Taurus style: nature, good food, physical sensuality, roots, resources, and perseverance.
Concretely, the person expresses personal dream, play instinct, inner child, childhood imprint, mother figure, mother image, optimism, and inner rhythm through the Taurus style (nature, good food, physical sensuality, roots, resources, and perseverance). Exact aspects and repeated patterns indicate whether this theme becomes central.
Aspect connected to this placement: Moon sextile Jupiter (orb 0.8°). Aspect effect: lets personal dream and fulfillment cooperate when optimism becomes a concrete horizon. Mother-image layer: childhood, mother image, and inner child can cooperate with Jupiter.
Time-sensitive Moon aspect: Moon sextile Jupiter (orb 0.8°). Because the birth time is unknown, the Moon's exact degree can shift during the day. This interpretation stays provisional and gains weight only if the aspect remains tight across the possible birth window or repeats another clear signature.
Here, Moon in Taurus brings personal dream, play, inner child, childhood imprint, mother figure, mother image, optimism, and inner rhythm with Taurus style (nature, good food, physical sensuality, roots, resources, and perseverance); Jupiter in Pisces brings personal fulfillment, confidence, encouragement, and broader horizons with Pisces style (imagination, faith, compassion, dream, and permeability).
Concrete cooperation: personal dream and fulfillment can cooperate when optimism becomes a concrete horizon. Mother-image layer: childhood, mother image, and inner child can cooperate with Jupiter.
The Rising sign cannot be determined if the time is not known.
