Documented path
Yamashita was born in 1995 in Japan. She represented Japan at the 2013 International Mathematical Olympiad, earning a silver medal. She dropped out of a prestigious high school after one year to attend a correspondence school and focus on mathematics. She entered the University of Tokyo, where she again accelerated, completing her bachelor's in three years and her master's by 2019. She was appointed assistant professor at Kyoto University's Research Institute for Mathematical Sciences at age 23, one of the world's leading math institutes.
Born in 1995 in Japan; enjoyed puzzles and sudoku from a young age. Family background not documented in reviewed sources.
Associate Professor at Kyoto University; recipient of the Maryam Mirzakhani New Frontiers Prize (2024) and Dannie Heineman Prize (2024).
Where the conditions came from
Each is placed on a −1 to 3 scale from documented evidence, and the three are never added together. A combined total would rank Mayuko Yamashita against other people. Held apart, they explain why this path ran differently from another one—which is the only comparison this project supports.
The marble itself
+2Tailwind
What capability, drive, or early skill is documented in the person rather than their surroundings?
Showed early talent in puzzles and sudoku from childhood. Won IMO 2013 silver medal representing Japan. Accelerated through the University of Tokyo, dropping out of bachelor's early to enter graduate school, completing her PhD by 2022 and becoming assistant professor at Kyoto University RIMS at 23.
Where it was dropped
0Neither way
What money, family standing, network, or permission was already in place before the work began?
Born in the Tokyo area, Japan. No notable family wealth, academic lineage, or domain connections found in available sources. Family background not well documented.
The shape of the track
+2Tailwind
What place, timing, institution, or peer group made the next step available?
University of Tokyo for undergraduate and graduate studies, then Kyoto University's Research Institute for Mathematical Sciences (RIMS). PhD supervised by Yasuyuki Kawahigashi at the University of Tokyo. Strong Japanese mathematical ecosystem, though not at the level of ENS or Princeton.
A −1 is a documented headwind, not a missing value; a 0 means the sources record nothing notable either way. Annotation confidence: Medium. These are analyst readings of what the sources record, not measurements of merit, talent, or effort. The twenty-two scored dimensions remain available inside the deeper research detail.
What moved through the conditions
This records repeated behaviour or recovery described by sources; it is not a grit or merit score.
A successful-only archive cannot recover all encounters, avoided setbacks, or alternative outcomes.
Strongest documented signals: Elite institution pipeline, Prodigy / innate ability, Frontier geography.
Describes the starting position, not what the person later made of it.
Strongest observed levers: Started serious reps before 20, Prior reps, Scarce skill depth.
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.
Notable and widely recognized within the domain. The tier summarizes documented career recognition through the data cutoff—not Mayuko Yamashita'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.
This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Mayuko Yamashita'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."
