Naoyuki Koike (小池直幸) has been competing for 3 years. His best event is the 3×3 blindfolded: a personal-best single of 18.76, set at Tokyo BLD Summer 2026, puts him in the top 0.95% of the 12,178 people who have ever been ranked in the event, and 4th in Japan. Until November 2016, no official 3×3 blindfolded solve in the world had been that fast. Across 11 competitions since September 2023, he has put 62 official solves on the record across three events.

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.
