Masayoshi Son’s BaZi chart 孙正义
Founder of SoftBank · born 11 August 1957, Tosu, Saga, Japan · date source: Wikipedia
Western zodiac sign: Leo.
No birth time has been published. The date fixes three of the four pillars; the fourth is one of twelve. Below, everything the date settles is computed, and everything that turns on the hour is cast all twelve ways — without picking one on anyone’s behalf.
In short
Masayoshi Son’s day master is Yin Wood: the Vine.
Gentle and kind, and puts roots down deep once it finds its place. The day master comes from the day of birth alone; about one person in ten shares it.

What the labels mean
Each pillar is two characters: a stem on top (an element, yin or yang) and a branch below (one of the twelve zodiac animals). The day stem is the day master — the person. The label above each other stem is its ten god (Shi Shen, 十神): what that element is to the day master.
Each animal also hides stems of its own, strongest first: the Rooster hides Yin Metal (辛, Seven Killings); the Monkey hides Yang Metal (庚, Direct Officer), Yang Water (壬, Direct Resource), Yang Earth (戊, Direct Wealth); the Rabbit hides Yin Wood (乙, Friend).
- Eating God (Shi Shen, 食神)
- What you produce, same polarity. Output that comes easily: making, feeding, expressing, without strain.
- Seven Killings (Qi Sha, 七杀)
- What controls you, same polarity. Pressure with nothing softening it: demand, risk, and whatever you answer to whether you chose it or not.
- Direct Wealth (Zheng Cai, 正财)
- What you control, opposite polarity. Wealth held steadily — earned, kept, accounted for.
- Direct Officer (Zheng Guan, 正官)
- What controls you, opposite polarity. Authority in its orderly form: office, rule, the structure you fit into.
- Direct Resource (Zheng Yin, 正印)
- What produces you, opposite polarity. Straightforward support: what teaches, shelters and backs you.
- Friend (Bi Jian, 比肩)
- Same element, same polarity as you. A peer: someone standing where you stand, competing for the same thing and equally able to share the load.
Day master
What the classic Di Tian Sui (滴天髓) says of this stem, word for word
Yin Wood (乙) though soft cuts the sheep and dismembers the ox. Holding Yin Fire (丁) and embracing Yang Fire (丙), it bestrides the phoenix and mounts the monkey. On empty wet ground, riding the horse is a worry still; but vine tied to Yang Wood (甲), it can take spring or autumn.
乙木虽柔，刲羊解牛，怀丁抱丙，跨凤乘猴，虚湿之地，骑马亦忧，藤罗系甲，可春可秋。
Born in a Monkey month (Shen, 申), when Metal rules the season. In that season Yin Wood is dead (Si, 死): the season controls it. (One of five seasonal states, Wang Xiang Xiu Qiu Si, 旺相休囚死, after the San Ming Tong Hui, 三命通會, book 2.)
Day pillar: Wood Rabbit (Yi Mao, 乙卯)
The classic San Ming Tong Hui (三命通会) gives each of the sixty day pillars an image, its sound element (Na Yin, 纳音). For this one it is Water of the Great Stream (大溪水), and it says:
Dew; likes Water and Fire.
The original Chinese
露也，喜水及火
This is what the book says of every Yi Mao day, not of Masayoshi Son. The Yi Mao day pillar › (what the classic says at each birth hour, what the branch holds, and others born on one)
Elements in the six known characters
None of the six is Water. The hour pillar’s two characters may supply it or may not — that depends on the hour. Hidden stems are not counted here.
All twelve hours, cast one by one
In all twelve hours the Yin Wood day master reads weak. Whatever the hour, the support-and-restrain method favours Water, Wood — the date alone settles it.

Each row is exactly what the full calculator would say for a birth in that hour. Strength comes from three tests: in season (De Ling, 得令) — born in the season of the day master’s own element; rooted (De Di, 得地) — the same element hidden in a branch; backed (De Shi, 得势) — as much support around it as drain. Two of three reads strong. The favoured elements come from support and restrain (Fu Yi, 扶抑): a strong day master wants draining, a weak one wants support. There are three other methods for the useful element — climate (Tiao Hou, 调候), bridging (Tong Guan, 通關) and disease and cure (Bing Yao, 病藥) — each from its own text; see the useful god page. Hours are solar time at the birthplace, so a clock time needs correcting first; and a birth after 23:00 falls in the late Rat hour, where the two schools disagree about whether the day has turned.
Masayoshi Son’s bone weight (Cheng Gu, 称骨)
Lunar date: day 16 of the 7th month, Fire Rooster year (丁酉年七月十六). Its weights: year 1.4 liang, month 0.9 liang, day 0.8 liang — 3.1 liang before the hour. Over the twelve hours that makes 3.7 liang to 4.7 liang.
Bone weighing is a folk almanac sum over the calendar positions of the year, month, day and hour — not the elements, and not the chart above. How heavy is heavy? The tables and the spread ›
And yours?
You have your own birth time, so your chart needs no table of twelve — all four pillars, corrected to true solar time with the timezone actually in force where and when you were born.
About this page
This page computes; it does not interpret. The birth date is public and its source is linked; the birth time is not, so the hour pillar and everything that depends on it are set out all twelve ways.
Nothing here claims that anyone is who they are because of a chart, and nothing here forecasts years, health or lifespan for anyone living.
Your own 2027, month by month
The full report reads 2027 month by month from your own birth date, time and place.
