Yūna Mizumori

Yūna Mizumori is a Japanese professional wrestler currently competing for World Wonder Ring Stardom. She holds the STARDOM High Speed Championship and serves as a core member of the Cosmic Angels stable. Known for her exceptional agility and speed, Mizumori blends high-flying maneuvers with technical grappling to outmaneuver larger opponents.

Her career trajectory shifted from the independent circuit to the national stage after a successful debut in 2018. Fans appreciate her energetic in-ring style and her ability to perform consistently at a high level within the fast-paced division. [edit]

Mizumori did not follow a traditional path to stardom immediately upon entering the industry. Before joining major leagues, she spent several years honing her craft on the Japanese independent circuit. Her early career included significant tenures with promotions such as Gatoh Move Pro Wrestling and Ganbare Pro-Wrestling. These years were crucial for building a reputation for consistency and adaptability across different wrestling environments.

She made her official debut match on February 28, 2018, marking the transition from the local scene to the national spotlight. This period allowed her to develop the "high-speed" style that would eventually become her signature. The independent circuit provided a rigorous training ground where she could refine her quick footwork and learn to work both high-speed and powerhouse styles effectively.

While some early biographical snippets have erroneously labeled her as an idol or listed incorrect birthdates, authoritative sources confirm her strict focus on professional wrestling. Her dedication to the sport during these formative years laid the groundwork for her future success in one of Japan's premier promotions. [edit]

Mizumori's rise in Stardom has been marked by rapid progression and championship success. After debuting in 2018, she quickly integrated into the fast-paced division and became a core member of the "Cosmic Angels" stable around 2023. This group is celebrated for its technical prowess and teamwork, solidifying her status as a top-tier competitor.

On December 24, 2025, she achieved her most significant career milestone by defeating Mei Seira to win the STARDOM High Speed Championship for the first time during the Year-End Xmas Night show. She successfully retained the title at the STARDOM NIGHTER event in Korakuen Hall on February 14, 2026. Later that year on May 17, 2026, she defended the title against Gina in a narrow victory, marking her fourth successful defense.

In October 2026, she continued to hold the High Speed Championship while engaging in high-profile tag team matches. On October 29, 2026, she teamed with veteran Hirooki Goto to face the duo of Shingo Takagi and Natsupoi at the Ota Ward Gymnasium. Prior to this match, the team prayed for victory together at the Akasaka Hikawa Shrine, highlighting their bond and the significance of the upcoming bout. [edit]

Mizumori projects an image of a determined, hard-working underdog who relies on skill rather than gimmicks. Her social media presence on X (Twitter) (@mizm0ri) is active but focused primarily on match updates, promotional content, and behind-the-scenes glimpses of her training and travels. Fans associate her with the "High Speed" moniker due to her championship tenure and nickname. [edit]
