Ryosei Yamashita (山下遼成) has been competing for 2 years. His best event is the 3×3: a personal-best single of 10.37, set at Swisscubing Cup III 2026, puts him in the top 8.6% of the 288,433 people who have ever been ranked in the event, and 377th in Japan.

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.
