Keisuke Yaosaka (八百坂圭祐)

3×3 · top 7.5% of 288,433 all-time · competing since February 2023 · 2023YAOS01

Keisuke Yaosaka (八百坂圭祐) has been competing for 4 years. His best event is the 3×3: a personal-best single of 10.00, set at Tokyo Spring 2026, puts him in the top 7.5% of the 288,433 people who have ever been ranked in the event, and 332nd in Japan. Until May 2007, no official 3×3 solve in the world had been that fast. Across 18 competitions since February 2023, he has put 100 official solves on the record across one event. Solve to solve, his 3×3 times vary about 15% around a typical one; 85% of the 36,406 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 18.56 in February 2023 to 10.00, a 46% improvement. Keisuke has entered 18 competitions, more competitions than 96% of everyone who has ever competed.

The story so far

Competitions

Reading this page: a single is one solve's time · an average is the middle three of five solves, best and worst discarded · a PB is a personal best · a DNF (did not finish) is an attempt with no valid result: a popped piece, an unsolved face, an over-limit memorisation · top X% compares against everyone ever ranked in that event, which is fairer than raw rank because event pools differ tenfold.
