KUMAMOTO, Japan, November 13, 2026 – Japan’s top seed Akane Yamaguchi will face China’s third seed Chen Yu Fei in a highly anticipated women’s singles semifinal at the Kumamoto Masters Japan 2026 after both players secured contrasting quarterfinal victories on Friday.
Yamaguchi defeated compatriot Riko Gunji 21-13, 21-12 in straight games, while Chen recovered from a game down to overcome Thailand’s sixth seed Pornpawee Chochuwong 18-21, 21-17, 21-11.
The results set up a Japan-China showdown in Saturday’s semifinals, with the winner advancing to Sunday’s championship match at the BWF World Tour Super 500 tournament.
The other women’s singles semifinal will also feature Japan against China after fifth seed Tomoka Miyazaki and second seed Wang Zhi Yi advanced from the lower half of the draw.
Meanwhile, Malaysia’s Aaron Tai and Yap Roy King continued their impressive men’s doubles campaign, while several established international pairs secured semifinal places in women’s doubles and mixed doubles.
Akane Yamaguchi Cruises Past Riko Gunji at Kumamoto Masters
Playing on home soil, Akane Yamaguchi maintained her pursuit of the Kumamoto Masters women’s singles title with a convincing victory over fellow Japanese player Riko Gunji.
The tournament’s top seed claimed the opening game 21-13 before taking the second 21-12, completing a straight-game victory to reach the last four.
Yamaguchi’s performance continued her successful campaign in Kumamoto, where she entered the tournament as the highest-seeded women’s singles player.
Her victory also ensured that Japan would have at least one representative in the upper half of the women’s singles semifinals.
However, the challenge becomes considerably greater in the next round.
Yamaguchi will face China’s third seed Chen Yu Fei, who advanced through a demanding three-game encounter against Thailand’s Pornpawee Chochuwong.
The semifinal brings together two of the leading names in international women’s singles badminton, with both players seeking a place in the Kumamoto Masters final.

Chen Yu Fei Fights Back to Defeat Pornpawee Chochuwong
While Yamaguchi progressed in straight games, Chen Yu Fei had to recover from an opening-game defeat to secure her semifinal place.
The Chinese third seed faced Thailand’s sixth seed Pornpawee Chochuwong in one of the more competitive women’s singles quarterfinals.
Pornpawee made the stronger start, claiming the opening game 21-18 to put Chen under pressure.
However, Chen responded by winning the second game 21-17, forcing a deciding game.
The Chinese star then took control of the final game, winning 21-11 to complete a 18-21, 21-17, 21-11 comeback victory.
The result ended Pornpawee’s campaign and kept Chen in contention for the Kumamoto Masters title.
More importantly, it confirmed a semifinal meeting with Yamaguchi, setting up one of the standout matches of Saturday’s schedule.
Unlike her Japanese opponent, who reached the semifinals without dropping a game in the quarterfinals, Chen had to overcome a deficit to advance.
Both players will now compete for a place in the final, with the outcome also determining which nation will be represented in the championship match from the upper half of the draw.
Wang Zhi Yi Overcomes Nozomi Okuhara in Three Games
China’s second seed Wang Zhi Yi also faced a three-game challenge before securing her semifinal place.
Wang defeated Japan’s eighth seed Nozomi Okuhara 21-17, 19-21, 21-8 in another quarterfinal featuring two established women’s singles competitors.
The Chinese player took the opening game 21-17, but Okuhara responded by winning the second 21-19 to level the match.
With the contest tied at one game apiece, Wang produced a much more decisive result in the third, winning 21-8 to advance.
The victory kept Wang’s title hopes alive and ensured that China would have two representatives in the women’s singles semifinals.
Wang will next face Japan’s Tomoka Miyazaki, who advanced with a straight-game victory over Chinese Taipei’s Lin Hsiang Ti.
Tomoka Miyazaki Joins Yamaguchi in Women’s Singles Semifinals
Japan’s fifth seed Tomoka Miyazaki secured her semifinal place after defeating Chinese Taipei’s Lin Hsiang Ti 21-14, 21-12.
Miyazaki took the opening game 21-14 before winning the second 21-12, completing a comfortable straight-game result.
Her progression means Japan will have two players in the women’s singles semifinals, matching China’s representation through Chen Yu Fei and Wang Zhi Yi.
The semifinal draw therefore features two Japan-China encounters: Akane Yamaguchi against Chen Yu Fei and Tomoka Miyazaki against Wang Zhi Yi.
With all four semifinalists seeded among the tournament’s top five, the women’s singles competition has retained several of its leading contenders heading into the final weekend.
