Kansai Mega Day 2025

Fifty-nine competitors stepped up to tackle twelve dodecahedral faces as the Megaminx served as the central focus of Kansai Mega Day 2025. Held on November 2, 2025, at the Daito Civic Hall in Daito, Osaka, Japan, the one-day gathering assembled 107 competitors across two distinct disciplines. While standard cubes often capture the spotlight at a traditional cubing competition, this meeting placed the complex geometry of dodecahedrons and the speed of three-layered puzzles on equal footing across six full rounds of play.

Masayuki Hirai delivered an exceptional performance to claim the Megaminx crown on home soil. Across three challenging rounds, Hirai maintained blistering turn rates, ultimately securing victory in the final with a winning average of 33.33 seconds and a best single time of 31.70 seconds. The podium battle highlighted the high standard of Japanese speedcubing, with Takumi Kawazoe taking second place with an average of 36.40 seconds and Wataru Takamiya claiming third with a mark of 38.97 seconds.

The 3x3x3 Cube contest welcomed a massive field of 104 competitors seeking top marks in the classic Rubik's Cube. Itthikorn Jittaveeroj from Thailand took the top step of the podium, posting a winning average of 7.65 seconds alongside a best single effort of 7.40 seconds. Jittaveeroj held off a strong challenge from Megaminx champion Masayuki Hirai, who finished as runner-up with an average of 7.86 seconds, while Kantaro Sakamoto completed the podium in third place with an 8.00 average.

The 3x3 results across the weekend reflected strong progress throughout the field in Daito, Osaka, Japan. International representation was sharp at the sharp end of the standings, with Japan collecting five podium places and Thailand taking one. Competitors advanced through three preliminary rounds to earn a spot in the finals, making Kansai Mega Day 2025 a test of stamina across both the twelve-sided puzzle and the standard three-layered cube.

Behind the top positions on the podium, numerous competitors made significant breakthroughs across both events on the schedule. Fumitaka Nakamura delivered a standout performance by dropping his Megaminx personal best to 54.28 seconds, an improvement of 29.9 percent over his previous mark of 1:17.45, while also lowering his 3x3x3 Cube personal best by 15.4 percent to 8.80 seconds. Shodai Kitagawa took on two events, logging his first ever attempt at Megaminx with a time of 1:44.34 and improving his 3x3x3 Cube personal best by 19.5 percent down to 12.30 seconds. Hiroki Goto also tackled both events, recording a 1:07.07 in his first official Megaminx solve and shaving 13.6 percent off his 3x3x3 Cube best with a 9.86 single.

The progress continued across the venue as competitors expanded their event repertoires. Shunichi Hirota registered his first ever attempt at Megaminx with a time of 2:21.99 while dropping his 3x3x3 Cube best to 10.10 seconds, an improvement of 9.7 percent. Keito Kawamoto entered two events, logging a first Megaminx attempt of 1:12.83, securing a best finish of 10th in the 3x3x3 Cube, and bettering his 3x3x3 personal record by 9 percent with a time of 7.42 seconds. Xiaodan Cai logged a first Megaminx result of 1:13.49 and improved his 3x3x3 single by 5.2 percent to 9.92 seconds. Taiki Nakatani completed his first Megaminx solve in 1:14.57 alongside a 10.98 personal best in the 3x3x3 Cube, while Hoàng Quốc Huy recorded a 1:50.19 in his first Megaminx appearance and notched a 11.34 personal best on the 3x3x3 Cube.

The energy across the floor demonstrated the vitality of the local speed cubing community as autumn competition schedules reached their stride in the Kansai region. Organizing a WCA competition with multiple rounds of Megaminx provided dedicated dodecahedron solvers an ideal platform to benchmark their turning precision alongside standard solving formats. The 2025 gathering in Daito confirmed the enduring popularity of specialized event formats.

As the final stopwatches clicked shut and equipment was packed away, Kansai Mega Day 2025 concluded having delivered high-level performances and personal milestones across every stage. Whether racing through the 120 colored pieces of the Megaminx or executing lightning-fast algorithms in the 3x3x3 Cube, the 107 solvers left Osaka with valuable experience and updated personal records for the season ahead.
