Yusei Kawasaki (川崎悠生) has been competing for 4 years. His best event is the 2×2: a personal-best single of 2.04, set at Tokyo Spring 2026, puts him in the top 5.0% of the 189,179 people who have ever been ranked in the event, and 61st in Japan. Until February 2008, no official 2×2 solve in the world had been that fast. Across 7 competitions since February 2023, he has put 94 official solves on the record across seven events. Solve to solve, his 3×3 times vary about 9% around a typical one, an early reading from 9 counted rounds. His 3×3 best has come down from 13.56 in February 2023 to 9.33, a 31% improvement. Yusei has entered seven competitions, more competitions than 88% 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.
