Masayuki Yasui (安井昌幸) has been competing for a year. His best event is the 2×2: a personal-best single of 1.52, set at Japan Championship 2026, puts him in the top 2.2% of the 189,179 people who have ever been ranked in the event, and 29th in Japan. Until November 2008, no official 2×2 solve in the world had been that fast. Across 6 competitions since June 2025, he has put 80 official solves on the record across six events.

Masayuki has entered six competitions, more competitions than 86% of everyone who has ever competed.

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.
