Hideyoshi, and a Rule Nobody Alive Can Apply

A column published on Nikkan SPA! on October 27, excerpted from Rinoie Yuchiku's book Kyoyo to shite no Fusui (Feng Shui as Cultural Literacy), sets out why feng shui would not describe Toyotomi Hideyoshi as a successful man. The reasoning is not about his castles or his campaigns. It is a definition: the title is awarded to a house, not a person, and only once that house has run three generations. Hideyoshi's did not, and the column reads that as the bodily soul — the part of the soul that stays with the bones and is supposed to support descendants — having been spent by one man instead of passed down.

The first half of that piece is accurate, and worth saying so before we disagree with anything. Classical feng shui did weight the grave, the yin dwelling, above the house, the yang dwelling; the split of the soul into a spirit soul and a bodily soul is the stated mechanism; and graves really were a military target, which is the kind of detail that gets left out of the modern version. None of that is our quarrel. Our quarrel is with the rule in the second half, and it is not that the rule is false.

A rule with no prospective form

“

In feng shui, "successful person" is a title given only once a line has continued for three generations.

Read that as an instruction and see what you can do with it. A reader choosing a house this year cannot apply it. A family choosing a burial site this month cannot apply it. The person whose success is being adjudicated cannot apply it, because the answer arrives two generations after their funeral. Every input is in place at the moment of the decision and the output is withheld for roughly a century.

That is a different thing from a slow calculation. A long-period claim still has prospective content if it says what to expect — the Flying Star period changes in 2044, and a chart drawn now says what the palaces will hold then, so somebody can write it down and be wrong. Here there is nothing to write down. The rule does not predict that a line will run three generations, or say which sites produce one; it declines to use the word until a line already has. Any outcome is consistent with it, which is why it never fails, and why it never helps.

Three generations, counted

Since the rule turns on a number, the number is worth counting. Toyotomi Hideyoshi died in 1598. His son Hideyori was born in 1593 and died at Osaka in 1615. Hideyori's son Kunimatsu was seven years old in 1615 — the third generation of the male line, and he was born, which is the part that matters for a count of generations. The standard account has him captured by Tokugawa forces after the castle fell and beheaded; Japanese tradition also carries survival stories about a tunnel and a substitute, which we mention because they exist and not because we can weigh them. Hideyori's daughter was spared on condition that she enter a convent, and became the twentieth abbess of Tokeiji.

So the line did reach a third generation and did not continue past it. Whether that counts as continuing for three generations is exactly the question the rule leaves open: it supplies a number without supplying what satisfies the number. A grandson born and killed at seven either counts or does not, and nothing in the stated rule decides which. A reader cannot audit a verdict whose central term is undefined — not because the verdict is unreasonable, but because there is no procedure to run.

What happened in 1615 needs no soul in it

The column's mechanism is that Hideyoshi spent the bodily soul himself and so left his descendants nothing to draw on. Set that beside the ordinary account. A siege was lost, the winning side executed the heir — a child of seven — and placed the surviving daughter in a convent where she would have no children. Lines end under those conditions with great regularity, and they end for families whose graves nobody has ever criticized.

This is the part of these arguments that we think is worth naming every time, because it is not a quarrel about metaphysics. Two accounts here predict the same thing. One of them does so by invoking a quantity nobody can measure, after the fact, in a case where a sufficient cause is already on the record and is not in dispute. Adding the bodily soul to that story changes no expectation about 1615 and generates no expectation about anything else. The honest summary is that it is a reading of the outcome, not an explanation of it — and a reading is allowed to be that, so long as it is not presented as the reason.

The headline, and the article underneath it

Worth being precise about who claims what. The headline joins two things — that the grave outranks the house of the living, and that Hideyoshi was no success — and a reader will take the second to follow from the first. The article does not say that. Asked directly, it decouples them: the grave is not what settled Hideyoshi's fate, and grave-siting practice is described as a means of handing success onward rather than as the cause of this particular collapse. That is a more careful position than the headline gives it credit for, and it is the headline we are disagreeing with on that point, not the author.

Which leaves the grave-siting material standing roughly where the column puts it, as history rather than as a tool. We do not compute any of it. Our calculators answer Eight Mansions, Flying Stars, the branch relations and date selection, all of which read a living building or a living person and all of which can be checked against a published table the same afternoon. Grave siting is Form School — the branch that needs no compass, judged on land and surroundings — and it is the branch whose outputs we have no way to verify, which is why there is no tool here for it and no plan to add one.

The reason to write any of this down is not that a newspaper column overreached. It is that the three-generation rule is a clean example of a shape that turns up constantly in this field and is easy to miss, because it sounds like rigor. A long horizon reads as patience and seriousness, especially next to a forecast for next Tuesday. But the horizon is not what makes a claim serious; having an answer that could come back wrong is. A rule that waits three generations and then declares which way it was going is not being careful. It is being unavailable.
