History of the Tournament
The history of professional tennis tournaments in Japan for women has a long and varied timeline. The Japan Women’s Open, in its current form, was established in 2009 as a successor to the co-ed Japan Open, which had been a combined ATP and WTA event until 2008. The newly created women’s-only tournament initially took place in Osaka, at the Utsubo Tennis Center, from 2009 to 2014.
The event underwent a series of relocations in the following years, moving to Tokyo from 2015 to 2017 and then to Hiroshima from 2018 to 2019. The tournament returned to Osaka in 2023, following a three-year hiatus due to the COVID-19 pandemic and other financial challenges. This return marked a new era for the tournament as a WTA 250 event. Notable past champions include Marion Bartoli, Samantha Stosur (a three-time champion), and Hsieh Su-wei. The most recent champions before 2025 were Ashlyn Krueger in 2023 and Suzan Lamens in 2024.
