Kanto Autumn PM 2025

A blistering 6.76 second average on the traditional 3x3x3 puzzle stood out as the defining performance in Ota, Tokyo, Japan. Kantaro Sakamoto captured the premier title with relentless consistency across two rounds of play, delivering a 6.15 best single solve during the afternoon clash. The one-day tournament brought together 76 competitors on October 11, 2025, each taking the floor across two featured events to test their speed under official conditions. Sakamoto commanded the main stage, leaving no doubt about his form as he claimed the top step of the podium.

The 3x3x3 Cube field gathered 72 contenders at the Ota ward plaza venue, creating a dense schedule of high-stakes solves. Shu Ogawa took second place overall with a steady 7.82 average, while Hajime Miyazaki secured third place by logging an 8.54 average in the final round. Fast turns defined every phase of the event, with the top tier of finalists pushing through rapid inspections and swift turn execution to determine the final 3x3 results in the Japanese capital.

The single-day schedule at Kanto Autumn PM 2025 maintained high intensity from start to finish. Over the course of four rounds divided across two events, the cubing competition delivered exceptional efficiency and high-level execution. Enthusiasts watching the speedcubing action saw competitors move seamlessly between standard three-layered puzzles and complex twelve-sided dodecahedrons. With Japanese solvers sweeping all six podium positions across the two disciplines, the gathering served as a sharp showcase of regional mastery in competitive solving.

Beyond the traditional cube, the Megaminx event provided an equally intense battle among 56 entrants across two rounds. Masayuki Hirai captured first place by producing a 31.78 winning average alongside the best single solve of the event at 30.45 seconds. Takumi Kawazoe chased closely behind to secure second place with a 34.65 average, while Yusuke Takada rounded out the Megaminx podium in third place with a mark of 39.83. The intricate puzzle challenged fingertip dexterity and lookahead across numerous faces.
