Yanmar Hanasaka Stadium (}ヤンマーハナサカスタジアム), a.k.a. “Nagai Ballgame Field” (長居球技場), is a stadium located in Nagai Park, Higashisumiyoshi-ku, Osaka, Japan. It plays host to J.League association football, international rugby, Japan Rugby League One, and X-League American football games. The 24,481-seat stadium is the third stadium in the Nagai Complex, along with Nagai Stadium and Nagai Aid Stadium.

After the first renovation of the stadium in 2010, its naming rights was handed over to the Dainihon Jochugiku Company (大日本除虫菊株式会社; Kincho) for 36 million yen a year for eight years. Thus, the stadium became the "Kincho Stadium (キンチョウスタジアム)". Kincho also became the shirt sponsor for Cerezo Osaka.

In 2021, after another renovation, the stadium was renamed to "Yodoko Sakura Stadium (ヨドコウ桜スタジアム)" after the Yodogawa Steel Works (株式会社淀川製鋼所), which signed a comprehensive partnership agreement with Cerezo Osaka.
