Ashima Shiraishi

Ashima Shiraishi is a young sportsperson from United States. climbed the boulder problem Crown of Aragorn, graded V13, at the age of 10, becoming the youngest person of either sex to climb the grade; at 14 she climbed Horizon, the first female ascent of a V15 boulder problem. Ashima was 10 years old when it happened.

Early achievement is only meaningful when it is measured against adults. The distinction that matters is not precocity in the abstract but documented output at a standard competent adults are held to.

What separates a documented record from a family anecdote is that someone else wrote it down at the time. Ashima's is recorded in published reference sources, with a date and a figure attached, and that is the standard applied to every entry in this index. Where an age or a date is disputed in the sources, this page follows the published record and says so rather than choosing the more impressive number.

Records like this one rarely survive untouched. The age thresholds that define early achievement keep falling as training methods, coaching and access to competition spread to more countries, and each generation of young sportspersons reaches the standard a little sooner than the last. Whether Ashima's mark has since been beaten is noted above; the achievement itself is fixed to its date and stands on the record as it was set.
