Six days of Swimming at the Aichi-Nagoya 2026 Asian Games, from 20-25 September, delivered a World Record, a piece of Games history and a wave of teenage talent who produced outstanding results on the continental stage.
As the curtain comes down on the competition, World Aquatics looks back at the storylines that defined the week in the pool.
Ohashi Stuns with World Record
The standout swim of the Games came from 17-year-old Shin Ohashi (JPN), who clocked 2:04.83 in the Men's 200m Breaststroke to become the first man ever to break the 2:05 barrier in the event, eclipsing Qin Haiyang's (CHN) previous World Record set at the World Aquatics Championships 2023 in Fukuoka.
It capped a remarkable week for the teenager competing in front of his home crowd, as he also jointly won the 100m Breaststroke with China’s Dong Zhihao (58.64), Men’s 4x100m and Mixed 4x100m Medley Relay silvers, and bronze in the 50m Breaststroke.
Zhang Zhanshuo Rewrites the History Books
China's Zhang Zhanshuo became the first swimmer in Asian Games history to win seven gold medals at a single edition, surpassing the previous record of six held jointly by Rikako Ikee (JPN, Jakarta 2018) and Zhang Yufei (CHN, Hangzhou 2023).
His haul included four individual Freestyle golds from 200m through to 1500m. He set an Asian record of 1:43.49 in the 200m, Games records of 3:41.28 and 7:42.49 in the 400m and 800m respectively, and clinched gold with a time of 14:42.42 in the 1500m.
“I feel much calmer than I had imagined," Zhang said after winning the 400m Freestyle to complete his medal haul.
"Of course, I'm very happy to win these seven gold medals, and I will turn them into greater motivation going forward"
Zhang also helped China to set Asian records in the Men’s 4x100m Freestyle Relay (3:10.60) and 4x200m Freestyle Relay (7:00.17), and earned a gold in the Mixed 4x100m Medley Relay.
His dominant week contributed to China winning a record 30 gold medals and 54 medals overall in the pool, surpassing the 28 golds they won three years ago in Hangzhou.
Japan finished second in the medal table with seven golds and 37 medals overall.
Yu Zidi Headlines a New Wave
Few swimmers left a bigger mark on Aichi-Nagoya than 13-year-old Yu Zidi (CHN), who won three gold medals.
Her success included a World Junior Record of 2:06.10 in the Women’s 200m Medley – the second fastest swim of all time behind only Summer McIntosh's world record of 2:05.70.
Yu also clocked Games records of 2:05.08 in the 200m Butterfly and 4:28.56 in the 400m Medley.
“I don't see myself as a genius. What I've achieved has come from putting in the work, day after day,” she said.
Among the other young stars competing at Aichi-Nagoya 2026, Japan's Yumeki Kojima also enjoyed a stellar campaign, setting two World Junior records of his own. The 17-year-old won 400m Medley gold in 4:07.02, also a Games record, and clocked 1:55.36 as he narrowly missed out on gold to compatriot Tomoyuki Matsushita in the 200m Medley.
History For Bahrain, Chinese Taipei and Kyrgyzstan
Aichi-Nagoya also delivered breakthrough moments.
Mikhail Arkhangelskiy struck gold for Bahrain in the 50m Butterfly with a joint-Asian record time of 22.91, in doing so winning his nation’s first-ever Asian Games medal in Swimming.
Chinese Taipei won their first men’s Swimming gold medal at the Asian Games, with Wang Kuan-hung going one better than his silver at Hangzhou 2022 in the 200m Butterfly as he clinched victory in 1:55.05.
Kyrgyzstan also won their first-ever Swimming medal at an Asian Games, with Denis Petrashov claiming 200m Breaststroke silver in 2:08.67 in the race that saw Ohashi break the World Record.
