🔥 Worlds 2026: seven days
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.
🏆 Career highlights
- 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. - 2025 — All Japan Championships — champion
Men's singles at the 79th edition, December 2025. Akane Yamaguchi won the women's singles at the same event. - 2025 — Kumamoto Masters Japan — champion (Super 500)

Copenhagen. Lost the final to Kunlavut VITIDSARN (THA) 21-19, 18-21, 7-21. - 2023 — Asian Games — men's singles bronze
The 19th Games (Hangzhou 2022, held in 2023). He booked his semi-final place on 5 October by beating NG Tze Yong (MAS) 22-20, 21-15. Badminton has no third-place play-off, so reaching the semi-finals secures a medal.
📅 What's next

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).
