Measures what was present, not whether it was inherited, earned, self-built, external, or mixed.
The timeline below shows the sequence of work and transitions around the selected early milestone. It is evidence of a path, not proof that every step was necessary.
Legendary or globally iconic career standing. The tier summarizes documented career recognition through the data cutoff—not Masayoshi Son's worth or future potential.
Question four · where did the leverage come from?
Each non-zero lever gets a best-supported origin, evidence signals, and confidence. Unresolved is the honest default when the biography cannot distinguish self-built, advantage-enabled, earned, external, or mixed.
One or more documented starting advantages plausibly enabled this lever.
A structural wave is external to the person, even when their position improved access to it.
One or more documented starting advantages plausibly enabled this lever.
One or more documented starting advantages plausibly enabled this lever.

This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Masayoshi Son's outcome attributable to any origin.
Structural luck, Encounter luck, Event luck, Outcome variance can change every arrow in the path. This successful-only dataset cannot observe the near-identical paths that did not break through, so luck stays visible and unscored.
Multiplying capacity documented later in the path. Measures what was present, not whether it was inherited, earned, self-built, external, or mixed.
Access or conditions documented near the beginning of the path. Zero means "no clear evidence in reviewed sources," not "advantage was absent."
Born to Zainichi Korean parents in extreme poverty in Tosu, Saga Prefecture; father raised pigs and chickens and ran an illegal sake business; family faced discrimination as ethnic Koreans in Japan.
Not documented in reviewed sources.
Son was born to Zainichi Korean parents in extreme poverty in Tosu, Japan, living in a tin shack with pigs and facing ethnic discrimination. At age 16, he moved to the United States to attend high school and enrolled at UC Berkeley, where he was inspired by the microchip revolution. He made his first $1 million at age 20 by inventing an electronic translator and selling the patent to Sharp Corporation. He founded SoftBank in 1981 at age 23 as a software distributor, riding the personal computer wave. His early success was driven by intense focus, technological timing, and an adversity-forged determination rather than family resources or networks.
