Shotaro's chart is a small flame set twice over deep Water, with Metal and wet earth in the year behind it. The image the reading uses is a single star over a dark sea. It lights what is around it, and it is out there on its own.

What is RIIZE Shotaro's personality like?

He is the member who warms everyone else. Polite, proper, does things the correct way, and kind without making a show of it. The catch is that he keeps his own inside out of view, so people around him can feel a wall even while he is being nice to them.

He looks like he takes correction easily. Inside he argues back, then swallows it and carries it alone. The same depth of focus that makes him exceptional when he is absorbed in dance or song turns on him when a thought gets painful, and the reading is firm that anything addictive is a real danger for this chart. Perfectionism, sensitivity and a fastidious streak come from the same place.

READ MY SAJU

What does Shotaro's chart say about his career?

He is the type that seniors and decision-makers take to and pick. His chart sits comfortably with authority, and it rewards him for staying inside the lines rather than fighting them. That is a good chart for a company like SM.

Performing is his release valve. The reading says the very act of singing and dancing in front of people takes an energy that could embarrass him in private life and spends it safely on stage. Water and Metal drain his flame, so he does best around warm, upbeat people and in warm colours, red and green.

How does Shotaro fit with the other members?

Anton's chart carries the Wood that Shotaro's flame runs on, so that pairing feeds him. Eunseok is the reverse case. His chart is nearly all Metal and needs exactly the Fire Shotaro brings, which makes Shotaro more useful to Eunseok than the other way round.

Sohee's chart is mostly Water, the element that presses on Shotaro's flame. It is not a clash, but it is the heavier pairing in the group, and the two of them together read quieter than either does apart.

What is Korean astrology?

Korean astrology, called Saju (사주) and known in English as the Four Pillars of Destiny, reads a person from their exact birth moment rather than from a birth month alone. Four pillars, eight characters, five elements.

On method. A complete chart needs a birth time. Idol birth times are not public, so this reading works from three pillars rather than four, and says so rather than filling the gap with a guess. Your own reading uses all four.

COMMON QUESTIONS

What is Shotaro's birth chart in Korean astrology?

Shotaro was born on 25 November 2000. His chart reads 庚辰 for the year, 丁亥 for the month and 丁亥 for the day. His Day Master is 丁 Fire, in its inward, yin form.

Is Shotaro's Korean astrology the same as his zodiac sign?

No. His Western zodiac sign is Sagittarius, which comes from his birth month alone. Korean astrology builds a chart from his birth year, month and day, so it reads differently and in more detail.

What is RIIZE Shotaro's personality like?

He warms everyone around him and does things properly, but keeps his own inside hidden, so people feel a wall. He focuses deeply, which makes him exceptional on stage and vulnerable to painful thoughts off it.

Why does Shotaro seem hard to read?

His chart is warm toward others but keeps its own feelings out of view. He accepts what people say on the surface and works through his disagreement alone, so people sense a wall even when he is being kind.

Why does Shotaro's chart have no hour pillar?

A full Korean astrology chart has four pillars: year, month, day and hour. The hour pillar needs an exact birth time, which K-pop idols do not make public, so this reading works from the three pillars a birth date establishes.
