Taiki Harada (原田泰来) has been competing for a year. His best event is the 3×3: a personal-best single of 7.07, set at Tokyo Spring 2026, puts him in the top 1.4% of the 284,439 people who have ever been ranked in the event, and 65th in Japan. Until November 2010, no official 3×3 solve in the world had been that fast. Across 6 competitions since August 2025, he has put 66 official solves on the record across three events.

Taiki has entered six competitions, more competitions than 86% 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.
