9th Anniversary in Osaka was a professional wrestling event promoted by World Wonder Ring Stardom, held on January 26, 2020 at EDION Arena Osaka No.2 in Osaka, Japan. The main event notably featured former World of Stardom champion Kagetsu's last advertised match in the promotion before his impending retirement, surprisingly teaming with long-time rival Mayu Iwatani against the throwback pairing of Queen's Quest's Momo Watanabe and Tokyo Cyber Squad's Jungle Kyona (as JKGReeeeN).
