Hiroki Sakai’s zodiac sign and chart, in brief
Hiroki Sakai was born in Kashiwa, Japan, on 12 April 1990, a Thursday. Their zodiac sign is Aries, with the Moon in Scorpio. Hiroki turns 36 in 2026. No verified birth time is on file for Hiroki; the chart is cast for midday, without houses.
By element the count is four earth, four water, one fire and one air. By modality the count is five cardinal, four fixed and one mutable. Saturn, Uranus and Neptune all fall in Capricorn. They are slow planets, so the grouping is shared with people born around the same time. No two planets sit closer to an exact angle than Sun and Mars: a sextile, about 1.5° from exact at midday. Aspects to the Moon are not counted, because the Moon moves about thirteen degrees in a day. One planet was retrograde: Pluto. The Moon was waning gibbous, between full and last quarter.
StarMap's dataset holds 21 other people born on 12 April, among them Montserrat Caballé, Lisa Gerrard and David Letterman.

Hiroki Sakai’s Sun, Moon and rising sign
Sun sign
Aries
about 21° Aries at midday
An Aries Sun starts things. For Hiroki Sakai that points to energy that is direct and impatient with delay, and to feeling most like themselves when there is something to go first at. The work of this placement is finishing what the spark began.
Moon sign
Scorpio
in this sign all day; the degree depends on the birth time
The Moon in Scorpio feels everything and shows little. For Hiroki that suggests trust that is slow, private and absolute; betrayal, once it happens, is not forgotten. This Moon is restored by intimacy without performance and by time alone to let things move.
Rising sign
The rising sign changes about every two hours, so it cannot be known without a birth time. The table below shows which sign was rising over Kashiwa, Japan, at each hour of the day.
Hiroki Sakai’s rising sign, by birth time

Until then, this is the rising sign for every possible time of birth on 12 April 1990, computed for Kashiwa, Japan.

Hiroki Sakai’s planets, sign by sign
Each planet by sign: what the placement is traditionally taken to mean, not a claim about Hiroki Sakai’s private life.
With the Sun in Aries, Hiroki Sakai's sense of purpose tends to come alive when there is a clear start line. They probably feel most like themselves pushing into something new, though that energy can burn hot and fade before the finish. The typical pattern is a project launched with excitement, then handed off once the routine sets in.
For Hiroki, the Moon in Scorpio means emotional needs that run deep and private, and a preference for managing a hard feeling alone over explaining it while it is still raw. Trust builds slowly and is rarely given back once broken. Even among the people closest to them, this Moon is likely to need real privacy.
With Mercury in Taurus, Hiroki is likely to think slowly and thoroughly, and a conclusion once reached is rarely revisited without good reason. The communication style is plain and practical rather than showy. A new idea that clashes with what they already believe may have to wait a while for a hearing.
Venus in Pisces loves without much guard, and Hiroki probably values emotional and even spiritual connection over anything practical. The temptation can be to idealise a partner before really seeing them. Generosity in relationships comes easily here, and so does missing the moment when giving starts to outweigh getting.
Mars in Aquarius acts on principle, and its anger surfaces most over unfairness or hypocrisy rather than personal slights. Hiroki can detach from a conflict so thoroughly that the other person feels shut out. The issue tends to get argued with heat while the relationship itself is treated with strange calm.
Jupiter in Cancer
4° Cancer 05' at midday
growth and excess
For Hiroki, Jupiter in Cancer means growing by nurturing others and building a home that people want to return to. The excess can be protecting loved ones past the point they need it. Generosity here takes the form of home-cooked meals, open doors and an instinct to take in anyone who needs somewhere to land.
Saturn is at home in Capricorn, a placement that builds discipline as naturally as breathing and often takes on responsibility earlier than most. The doubt, for Hiroki, may be never quite believing that enough has been achieved to relax. Others tend to recognise this kind of authority well before it is claimed.
Uranus in Capricorn
9° Capricorn 35' at midday
freedom, generational
Many people within a few years of Hiroki's age share Uranus in Capricorn, the mark of a generation that dismantles and rebuilds old institutions and structures of authority. Personally, that can mean scepticism towards any system that asks for trust without having shown why it deserves it.
Neptune in Capricorn
14° Capricorn 34' at midday
imagination, generational
Neptune in Capricorn is shared by Hiroki and about fourteen years of births. The imagination of the generation questions or idealises authority and ambition, often shaped by wide disillusionment with institutions. The personal version may be an uneasy relationship with conventional success.
Pluto in Scorpio
17° Scorpio 04' at midday ℞
power, generational
Pluto is at home in Scorpio, and the generation born with it lives through profound upheavals in power, secrecy and shared taboos. Hiroki's own share may be an unusually deep comfort with intensity that others would find overwhelming.
Aspects in Hiroki Sakai’s chart
How the planets stand to each other, tightest first. Without a birth time the orbs are those at midday, and aspects to the Moon are left out because the Moon moves about thirteen degrees in a day.
Sun sextile Mars
about 1.5° at midday
Hiroki Sakai's identity and energy work together, giving them an easy confidence that is there when they decide to use it. With this aspect, taking the initiative comes more naturally than might be expected, especially when the stakes are theirs to own.
Mercury trine Uranus
about 1.7° at midday
Insight is likely to come to Hiroki fast and without much effort, the product of thinking and originality that flow together easily. With Mercury trine Uranus, new ideas tend to arrive when they are needed, often faster than they can be written down.
Venus trine Jupiter
about 1.9° at midday
Affection and a sense of plenty reinforce each other in Hiroki's chart, and the result is a warm, easy generosity in relationships. With this trine, goodwill in love and friendship tends to be given freely and returned in kind, without much forcing on either side.
Sun square Saturn
about 3.0° at midday
With the Sun square Saturn, confidence meets resistance, often in the form of self-doubt or an authority figure whose approval feels hard to win. When Hiroki pushes through it anyway, the achievement means more because it was tested.
Mercury trine Neptune
about 3.3° at midday
Hiroki probably has a natural gift for metaphor, storytelling and intuitive leaps, the work of thinking and imagination in easy partnership. With Mercury trine Neptune, communicating something hard to put into words comes easily, in a way that other people often find memorable.
Venus sextile Uranus
about 3.6° at midday
An independent streak and a warm heart get along in this sextile, which tends to give Hiroki's relationships room to breathe without cooling them. The freedom involved is easy and low on drama: enough to keep a relationship interesting, never so much that it feels unstable.
The rest, listed without a reading. Those between Uranus, Neptune and Pluto hold for years at a time, so everyone born while one holds shares it.

How this page is made
Planet positions are computed with the astronomy-engine ephemeris and checked against Swiss Ephemeris. Birth dates and places come from Wikidata; birth times, where StarMap has one, come from Astro-Databank and are shown with their Rodden rating. The readings describe what a placement is traditionally taken to mean. They are written by StarMap for reflection and entertainment, not as statements about the person’s private life. New to charts?
