76th All Japan Corporate Team Championships

All Japan Corporate Team Championships・Fukaya, Saitama, Japan

🆕NTT East reached the semi-finals, where Naraoka was named at third singles. 🔴BIPROGY took the tie 3-0, so the rubber was never played and he has no score at this event. The rules say a tie is stopped as soon as one team has won three of the five rubbers, and third singles is last in the order. Our tournament page counted 127 of the 435 rubbers in the knockout stage as never played, and this is one of them. ⚠️We write only what the official order sheets show; no reason for a player not appearing is published and we do not guess at one.

China Masters

Super 750・Shenzhen, China

In the quarter-final on 4 September he lost 10-21, 14-21 to 2nd seed Christo POPOV (FRA) and went out in the last eight.

Asian Games 2026

Asian Games・Ichinomiya, Aichi, Japan

One of the ten men in Japan's squad (named 19 May 2026); he had a bye in the first round of the men's singles. On Saturday 26 September he beat LEE Cheuk Yiu (HKG) 21-17, 11-21, 21-18 from a game down, then a player from Iran 21-11, 21-16 later the same day. 🔴In the quarter-final on Sunday 27 September he lost to YOO Tae Bin (KOR) 21-12, 5-21, 11-21 after winning the first game. Badminton at the Asian Games has no third-place play-off, so that match was for a medal (he took bronze at the previous edition, Hangzhou 2022, held in 2023). Yoo had beaten SHI Yu Qi (CHN) in the third round. We do not list who played which rubber in the men's team event (Japan lost 0-3 to India in the quarter-finals), because our tournament page does not record it.

The clearest way to read Naraoka's 2026 World Championships is by seedings. He came in as the 10th seed — the only seeded Japanese man in the draw — and then beat a higher seed on three consecutive days.

• 20 Aug, round of 16 — LI Shi Feng (CHN, 8th seed) 13-21, 23-21, 21-11. Eight points down in the opener, he took the second game 23-21 and the match turned.
• 21 Aug, quarter-final — Anders ANTONSEN (DEN, 4th seed) 21-19, 21-15 in straight games.
• 22 Aug, semi-final — CHOU Tien Chen (TPE, 6th seed) 17-21, 21-11, 21-10, taking the last two games by ten points each.

Naraoka had lost to Chou 13-21, 15-21 in the second round of the China Open five weeks earlier — that reversal is the story of Naraoka's summer.

• 2026 — BWF World Championships — runner-up (silver)
  23 August, New Delhi. Lost the final to Alex LANIER (FRA) 11-21, 11-21, having entered as the 10th seed.

He beat LI Shi Feng (CHN) 21-18, 21-7 in the first round and Brian YANG (CAN) 21-16, 21-11 in the second, both in straight games, then lost 10-21, 14-21 to 2nd seed Christo POPOV (FRA).
