Carlos Alcaraz defeated Jiri Lehecka 7–6(4), 6–4 in the Tokyo final on October 6, 2026, retaining the title. Trailing 2–4 in the opening tiebreak, he won five straight points to take the set. Lehecka’s lead disappeared without another point added to his side.
The second-set turning point came at 3–3. Alcaraz broke in that game and produced a passing-shot winner when Lehecka advanced. The official tournament account described a controlled finish, while Alcaraz assessed the final as his most consistent performance of the week.
In the preceding semifinal against Jaume Munar, Alcaraz had lost a 5–3 opening-set lead and the set 5–7 before recovering. The final again required him to solve a late first-set deficit. The tournament’s account of his title run highlighted drop shots, net approaches and changes of trajectory as tools he used to find solutions.
