Tokyo Summer 2026

Kohei Aruga delivered the defining performance of the season at Tokyo Summer 2026, capturing the 7x7x7 Cube title with a pair of Japanese national records. His blistering winning average of 2:07.95 and single of 2:01.56 established new domestic standards, setting the tone for a sharp single-day tournament. Held on June 13, 2026, at Ota ward plaza in Ota, Tokyo, Japan, the cubing competition served as a crucial mid-year showcase for 70 competitors across six fast-paced rounds.

The 2026 calendar has seen rapid evolution across big cubes and mechanical puzzles, and this competition offered a focused stage for specialized disciplines. Alongside traditional Rubik's Cube enthusiasts who routinely track standard 3x3 results, participants in Ota converged to test their skills on the large-layer cubes and the intricate Clock. Across three distinct disciplines, the single-day schedule placed immediate pressure on every entrant to deliver under tight conditions.

In the 7x7x7 Cube final, Aruga's record-breaking average of 2:07.95 carried him to the top of the podium ahead of a competitive field of 52 entrants. Ivan Li Ka Leong of Hong Kong, China, earned second place with a time of 2:12.13, while Yi-Fan Wu of Chinese Taipei secured third place with an average of 2:18.49. Aruga's national record single of 2:01.56 highlighted the absolute ceiling of big cube performance during the weekend.

Ivan Li Ka Leong reversed the order in the 6x6x6 Cube division, producing an authoritative victory at Tokyo Summer 2026. Li posted a winning average of 1:23.27 and recorded the best single solve of the event at 1:19.38 across two competitive rounds featuring 51 contenders. Aruga followed closely behind to claim the runner-up spot in 1:28.69, while Japan's Takeru Iguchi completed the podium with a third-place average of 1:31.17.

The Clock event delivered rapid-fire turnarounds among 49 competitors, ultimately won by Shoi Hamaguchi. Hamaguchi secured the gold with a balanced winning average of 4.09, further anchored by the weekend's best single solve of 2.92. Taku Yanai finished in second place with a 4.44 average, while Tomoki Yokoyama posted a 4.85 average to lock down third place in an all-Japan podium sweep for the event.

Away from the top steps of the podium, several competitors made substantial strides by taking on unfamiliar puzzles at this WCA competition. Ryota Yuzawa tackled three disciplines, achieving a personal high finish of ninth place in the 6x6x6 Cube with a first ever attempt of 1:34.55, while also recording a first ever attempt of 2:24.54 in the 7x7x7 Cube and a 4.16 in Clock. Takato Mori registered a notable Clock personal best of 20.71, dropping his previous mark by 15.5 percent, in addition to debuting on the 6x6x6 Cube in 9:25.91 and the 7x7x7 Cube in 14:15.00. Yusuke Kosaka shaved 10.4 percent off his previous Clock record with a personal best of 12.11, while logging a first attempt at the 6x6x6 Cube in 4:47.04.

Other athletes embraced the challenge of larger cubes and specialized gear across the tournament schedule. Rintaro Koide took on three events, posting a first ever attempt of 15:26.00 in the 7x7x7 Cube, 6:21.65 in the 6x6x6 Cube, and 17.35 in Clock. Mishti Asher stepped up in two events to log a first attempt in Clock at 21.20 alongside a 9:19.19 in the 6x6x6 Cube. Naoyuki Takahashi completed his first official solves in the 7x7x7 Cube at 10:31.00 and the 6x6x6 Cube at 7:10.47, while Kaito Suzuki registered opening marks of 3:25.17 on the 6x6x6 Cube and 7:02.12 on the 7x7x7 Cube.

With host nation Japan earning six podium positions, Hong Kong, China taking two, and Chinese Taipei claiming one, Tokyo Summer 2026 proved to be an efficient test of speedcubing mastery. The high-caliber marks in big cubes and Clock reinforced the strength of the region as the international season progresses. Competitors left Ota with valuable experience, national records, and established benchmarks for the next phase of the speed cubing circuit.

As the 2026 schedule moves deeper into the summer months, the results from Ota ward plaza highlight a rising standard across non-standard disciplines. The precision displayed at Tokyo Summer 2026 offers a clear reference point for solvers aiming to refine their strategies and shave crucial seconds off their averages before the season reaches its ultimate climax.
