Japan Open 2026

Super 750・Tokyo Metropolitan Gymnasium

He entered as the 6th seed and went out in the first round, losing 19-21, 6-21 in 45 minutes to Nhat Nguyen (IRL) on 15 July. Nguyen lost his next match the following day, 15-21, 19-21 to 🇯🇵Koki Watanabe, who went on to finish runner-up. ⚡Six days after this defeat the China Open began, and Chou won it (see nine straight wins, three defeats). 🆕Added on 17 September 2026: this match is not on our tournament page; the official BWF day data and the draw on English Wikipedia agree on the score, and the duration is from the BWF day data.

China Open 2026

Super 1000・Changzhou, China

He came in as the 6th seed and won the title. We hold all five of his matches, from the first round to the final, and he won all five: Brian YANG (CAN) 21-11, 21-9 in 29 minutes in the first round on 21 July, 🇯🇵Kodai Naraoka 21-13, 21-15 in the second round on 23 July, Shi Yuqi (CHN, 1st seed) 21-14, 12-21, 21-15 in the quarter-finals on 24 July, Lin Chun-yi (TPE) 21-18, 21-17 in the semi-finals on 25 July, and Toma Junior Popov (FRA) 21-15, 7-21, 21-13 in the final on 26 July. Our tournament page files the quarter-final as a first win over the world No. 1 after nine straight defeats. ⚡Two of those five beat him back later in our records (see nine straight wins, three defeats). 🆕Added on 17 September 2026: the first round is not on our tournament page, and this page used to say we held nothing from it; the official BWF day data and the draw on English Wikipedia agree on the score, and the duration is from the BWF day data.

BWF World Championships 2026

World Championships・New Delhi, India

He entered as the 6th seed and lost in the semi-finals, taking bronze. Our tournament page notes that there is no third-place play-off at the World Championships, so both beaten semi-finalists receive bronze. We hold all five of his matches, from the first round to the semi-final: Clarence VILLAFLOR (PHI) 21-12, 21-12 in 34 minutes on 17 August, Giovanni TOTI (ITA) 21-12, 21-11 in 33 minutes on 19 August, 🇯🇵Yushi Tanaka 21-14, 21-9 in 35 minutes on 20 August, Alwi Farhan (INA, 11th seed) 21-15, 21-15 in the quarter-finals on 21 August, and 🇯🇵Kodai Naraoka (10th seed) 21-17, 11-21, 10-21 in the semi-final on 22 August — a loss after taking the opening game 21-17. Our tournament page writes that last one from Naraoka's side as 17-21, 21-11, 21-10, and Badminton Spirit's day-four report carries the 35-minute duration of the third round. 🆕Added on 17 September 2026: the first two rounds are not on our tournament page, and this page used to say we recorded neither opponent nor score; for both matches the official BWF day data and the draw on English Wikipedia agree on the score, and the duration is from the BWF day data.

China Masters 2026

Super 750・Shenzhen, China

He entered as the 4th seed and went out in the first round, losing 20-22, 15-21 to Toma Junior Popov (FRA) on 2 September — beaten back 38 days after he had beaten the same player in the China Open final on 26 July (see nine straight wins, three defeats). Our tournament page files it among the upsets of 2 September outside the Japanese draw and writes it from Chou's side, as we do here. ⚠️That tournament page uses the BWF spelling "CHOU Tien Chen" throughout.

Up to 2 September we hold a score for twelve of his 2026 matches: nine wins and three defeats. In date order he lost on 15 July, won nine in a row, then lost twice from 22 August. 🔴Until 17 September 2026 this page said we held eight, with six wins and two defeats, and that both defeats were against players he had beaten. Four against non-Japanese opponents — the Japan Open first round, the China Open first round and the first two World Championships rounds — were missing from our tournament pages, and one of them was a defeat.

🔻The first defeat: the Japan Open first round on 15 July. As the 6th seed he lost 19-21, 6-21 in 45 minutes to Nhat Nguyen (IRL). Six days later he began a run of nine straight wins, from the China Open first round to the World Championships quarter-final.

🔁1. Kodai Naraoka (JPN) — reversed in 30 days. Chou won the China Open second round 21-13, 21-15 on 23 July; our tournament page notes that this ended the Japanese men's singles draw. Thirty days later, in the World Championships semi-final on 22 August, he lost 21-17, 11-21, 10-21 — after taking the opening game, and the nine-match run ended there.

🔁2. Toma Junior Popov (FRA) — reversed in 38 days. Chou won the China Open final 21-15, 7-21, 21-13 on 26 July for the title. Thirty-eight days later, in the China Masters first round on 2 September, he lost 20-22, 15-21 — out in his opening match as the 4th seed.

⚠️ This is what our own records hold, not a career head-to-head, which we do not have. Within the twelve matches up to 2 September he met the same opponent twice only in these two pairs, four matches in all (after that he met Koki Watanabe twice, in the Arctic Open quarter-final and the Denmark Open second round).

• 2026 — China Open champion (Super 1000)
  He beat Toma Junior Popov (FRA) 21-15, 7-21, 21-13 in the final on 26 July. Our tournament page and the English Wikipedia entry agree on that final. 🔴We originally called this his first Super 1000 title, and that was wrong. The tour title list on English Wikipedia and the career summary on Badminton Spirit both record his 2019 Indonesia Open (Super 1000) win. It was his second, seven years after the first, and we have corrected the tournament page.
• 2026 — World Championships bronze
  He lost the semi-final 21-17, 11-21, 10-21 to Kodai Naraoka (JPN, 10th seed) on 22 August. The medal table on our tournament page lists the men's singles bronzes as Chou Tien Chen (TPE) and Victor Lai (CAN), and the medal box on English Wikipedia also records the 2026 New Delhi bronze. It is his second World Championships medal, after bronze at Tokyo in 2022.
• 2019 — Indonesia Open champion (Super 1000)
  The tour title list on English Wikipedia gives the final as 21-18, 24-26, 21-15 over Anders Antonsen (DEN), and Badminton Spirit's career summary records the same 2019 Indonesia Open title. The 2026 China Open was his second Super 1000 title after this one. Antonsen is World No. 5 as of 8 September 2026.
• 2018 — Asian Games men's singles silver
  At the 2018 Jakarta–Palembang Games. The medal box on English Wikipedia (2018 men's singles silver and men's team bronze) and Badminton Spirit's career summary agree. ⚠️We hold no record of a medal for him at the last edition, the 2022 Games held in Hangzhou in 2023. We hold no match of his from the 2026 Games in Ichinomiya, Aichi, Japan (20 to 29 September).
• 2025 — Arctic Open champion (Super 500)
  Our Arctic Open 2026 page records him as the defending champion from 2025, beating Kunlavut Vitidsarn (THA) 21-11, 13-21, 21-19 in the final; English Wikipedia gives the same score. He also won the 2024 edition, where the final was against Jonatan Christie (INA). At the 2026 edition (6 to 11 October, Vantaa, Finland) he was the 3rd seed and lost in the quarter-finals to Koki Watanabe 19-21, 16-21, so there was no third straight title.

📅The most recent event we record is the Arctic Open 2026 (Super 500, Vantaa, Finland) from 6 to 11 October, where he reached the quarter-finals as the 3rd seed. He beat Arnaud MERKLE (FRA) 21-13, 19-21, 21-13 in the first round on 7 October and Yudai Okimoto 21-16, 21-19 in the second round on 8 October, then lost the quarter-final on 9 October to Koki Watanabe (8th seed) 19-21, 16-21, so there was no third straight title after 2024 and 2025. ⚠️These three matches are not in the twelve-match count (up to 2 September) on this page (scores from Chou's side). At the Denmark Open 2026 (13 to 18 October), now under way, he is the 3rd seed: he beat Koki Watanabe 21-19, 22-20 in the second round on 15 October and, as of 15 October, is through to the quarter-finals (last eight; we have not recorded his first-round score; the event runs until the 18th). ⚠️The Denmark match is not in the twelve-match count either. Before that came the China Masters 2026, which ended on 6 September (out in round one as the 4th seed).

The events after that for which we have a page are the French Open 2026 from 20 to 25 October, the Kumamoto Masters Japan 2026 from 10 to 15 November and the Hong Kong Open 2026 from 17 to 22 November.

🏆At the Arctic Open 2026 the top seed in men's singles was Kunlavut Vitidsarn, with Christo Popov 2nd and Anders Antonsen 4th; Antonsen won the title and Yushi Tanaka was runner-up. ⚠️ Our Asian Games 2026 page (20 to 29 September) holds no match of his. The French Open 2026 draw came out on 15 October: he is the 5th seed and meets 🇯🇵Yushi Tanaka in the first round (withdrawals after the draw are still possible). No entry lists have been published for the Kumamoto Masters Japan 2026 or the Hong Kong Open 2026. We do not guess who will play. The full calendar is on our 2026 badminton tournament schedule page.

"Nine wins and three defeats" says nothing about the order they came in. In date order our records read a defeat, nine straight wins, then two defeats. Five of those nine wins came at the China Open between 21 and 26 July, and four at the World Championships between 17 and 21 August.

🔴Until 17 September 2026 this page said six wins and two defeats. Our tournament pages follow the Japanese entries, so a match without a Japanese player is less likely to survive on them. The four matches we added are ones where the official BWF day data and the draw on English Wikipedia agree on the score. Counting from the BWF day data, he played twelve matches across these four events, and we now hold every one of them. Where we hold nothing, we say so; when we find it, we add it once two sources agree.

🇯🇵Read alongside a Japanese player's page and the same match looks different. On Kodai Naraoka's page, 22 August is the third of three seeds beaten on the way to the final. On Yushi Tanaka's page, 20 August is the match that stopped him one round short of the quarter-finals. Here they are the winning side and the losing side.
