Jin Kimura (木村仁) has been competing for 5 years. His best event is the 3×3: a personal-best single of 6.18, set at Kanto Summer 2026, puts him in the top 0.6% of the 284,439 people who have ever been ranked in the event, and 29th in Japan. Until June 2011, no official 3×3 solve in the world had been that fast. Across 11 competitions since December 2021, he has put 145 official solves on the record across six events. Solve to solve, his 3×3 times vary about 12% around a typical one, steadier than 71% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 11.87 in December 2021 to 6.18, a 48% improvement. Jin has entered eleven competitions, more competitions than 93% 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.
