The 2026 Japan Open in Osaka runs from October 19–25 with 32 singles players and 16 doubles teams. It is a WTA 250 on the outdoor hard courts at Utsubo Tennis Center. The official field checked on October 18 lists Ann Li as the top seed.
The finals fall on separate days. The WTA’s September 17 Asian-swing guide schedules doubles for Saturday, October 24, not before 3:30 p.m., and singles for Sunday, October 25, not before 1:30 p.m. Both times are Japan Standard Time, UTC+9.
The singles champion receives 250 ranking points and US$37,390. The runner-up receives 163 points and US$22,125, while a semifinal finish earns 98 points and US$12,331. Ningbo, held in the same week, is a WTA 500 with a different points scale.
Osaka became a women’s-only event in 2009 and returned as a WTA 250 in 2023 after a three-year hiatus. Recent champions are Ashlyn Krueger in 2023, Suzan Lamens in 2024 and Leylah Fernandez in 2025. The current field lists Peyton Stearns and Kimberly Birrell as the second and third seeds.
