Kosuke Koyama 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.
Kosuke Koyama's chart rests first on the stable factors: Sun in Sagittarius and Moon in Aries. Without a reliable time, signs and aspects are stronger than the Rising sign or houses.
Chart detail:
Sun conjunct Mars (orb 2°) gives a central dynamic in this reading. The orb is tight enough to count in the main reading.
In plain terms, this aspect makes ego, personal direction, courage, competition, and the need to act come out together.
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 Saturn in Capricorn
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 Sagittarius · Moon in Aries
First hook: this is where the chart often becomes recognizable in real life. Sun in Sagittarius: identity and direction move through expansion, travel, belief, and the search for meaning; Moon in Aries: emotional safety looks for initiative, speed, confrontation, and direct action. 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 circuit: Venus, Uranus, Moon, and Jupiter
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 Venus (attraction, pleasure, taste, and relationships), Uranus (change, freedom, rupture, and originality), Moon (emotional needs, instinct, and inner safety), and Jupiter (growth, faith, luck, and confidence in the future).
This is the clearest cooperation pattern in the chart: Venus trine Uranus (orb 3.4°), Moon trine Venus (orb 3.5°), and Jupiter sextile Uranus (orb 3°). 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: Venus, Neptune, Jupiter, and Mars
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 Venus (attraction, pleasure, taste, and relationships), Neptune (dreams, ideals, imagination, and confusion), Jupiter (growth, faith, luck, and confidence in the future), and Mars (action, anger, desire, and courage).
This is the clearest friction pattern in the chart: Venus square Neptune (orb 0.5°), Mars opposite Jupiter (orb 5.5°), and Venus opposite Jupiter (orb 6.4°). 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 Sagittarius remains a reliable combination even without a birth time. The Sun describes identity, ego, father figure, visibility, and direction, with Sagittarius style: expansion, travel, belief, and the search for meaning.
Concretely, the person expresses identity, ego, father figure, recognition, and personal direction through the Sagittarius style (expansion, travel, belief, and the search for meaning). Exact aspects and repeated patterns indicate whether this theme becomes central.
Aspect connected to this placement: Sun conjunct Mars (orb 2°). Aspect effect: makes ego, personal direction, courage, competition, and the need to act come out together.
Sun conjunct Mars (orb 2°) brings the two planets out together. The orb is tight enough to count in the main reading.
Here, both planets use the same Sagittarius style (expansion, travel, belief, and the search for meaning). Sun in Sagittarius brings identity, ego, father figure, visibility, and direction; Mars in Sagittarius brings action, courage, competition, and effort.
Concrete effect: this aspect makes ego, personal direction, courage, competition, and the need to act come out together.
Moon in Aries 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 Aries style: initiative, speed, confrontation, and direct action.
Concretely, the person expresses personal dream, play instinct, inner child, childhood imprint, mother figure, mother image, optimism, and inner rhythm through the Aries style (initiative, speed, confrontation, and direct action). Exact aspects and repeated patterns indicate whether this theme becomes central.
Aspect connected to this placement: Moon square Saturn (orb 0.6°). Aspect effect: can make the personal dream and mother image feel supervised by Saturn: play, spontaneity, or childlike confidence meets fear, duty, restraint, or the need to hold it together.
Time-sensitive Moon aspect: Moon square Saturn (orb 0.6°). 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 Aries brings personal dream, play, inner child, childhood imprint, mother figure, mother image, optimism, and inner rhythm with Aries style (initiative, speed, confrontation, and direct action); Saturn in Capricorn brings discipline, constraint, endurance, and mastery with Capricorn style (structure, ambition, responsibility, and long construction).
Concrete friction: this aspect can make the personal dream and mother image feel supervised by Saturn: play, spontaneity, or childlike confidence meets fear, duty, restraint, or the need to hold it together.
Time-sensitive Moon aspect: Moon trine Venus (orb 3.5°). 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 Aries brings personal dream, play, inner child, childhood imprint, mother figure, mother image, optimism, and inner rhythm with Aries style (initiative, speed, confrontation, and direct action); Venus in Sagittarius brings desire, taste, relationship, and attraction with Sagittarius style (expansion, travel, belief, and the search for meaning).
