Defending champion Chen Xingtong outclassed compatriot and No. 2 seed Kuai Man 4–1 on Sunday to reach the women's singles final at the WTT Champions Yokohama.

Kuai began nervously, gifting far too many unforced errors in the opening game as Chen seized control and took it 11–8. The second followed much the same pattern: Chen dictating tempo and closing it out 11–7, while Kuai, who had looked too comfortable in earlier rounds, struggled to match the raised intensity.

Kuai found her range in the third game, placing Chen under real pressure and leading 8–5 late. Chen answered with a two‑point run and Kuai called timeout, but Chen completed the turnaround to win 11–9.  

Kuai hit back in the fourth game with a confident 11–5 win. In the fifth, Chen steadied, relied on her rallying strength and control in the exchanges, and closed the match with another 11–5 result to win 4–1, booking a place in the final for the second consecutive edition.

In the other semifinal, China's Wang Yidi fell to Japan's Miwa Harimoto 2–4 (11–4, 10–12, 10–12, 12–14, 11–8, 6–11) sending Harimoto through to the final against Chen.
