Shouichi Yasumoto (安本翔一) has been competing for 16 years. His best event is the Megaminx: a personal-best single of 44.88, set at Kansai Mega Day 2025, puts him in the top 3.0% of the 34,786 people who have ever been ranked in the event, and 26th in Japan. Until April 2011, no official Megaminx solve in the world had been that fast. Across 25 competitions since January 2011, he has put 361 official solves on the record across nine events. Solve to solve, his 3×3 times vary about 13% around a typical one, steadier than 52% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 14.16 in January 2011 to 10.60, a 25% improvement. Shouichi has entered 25 competitions, more competitions than 98% 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.
