Yoshiko Hirano (born July 26, 1993), known mononymously as Yoshiko, is a Japanese professional wrestler and retired mixed martial artist, most recently working for Japanese promotion SEAdLINNNG, where she is a former one-time Beyond the Sea Single Champion and three-time Beyond the Sea Tag Team Champion.
She is also known for her time in World Wonder Ring Stardom, where she debuted in January 2011 and quickly formed a successful partnership with Natsuki☆Taiyo; the two would win the Goddesses of Stardom Championship and the 2012 Goddesses of Stardom Tag League. Following Taiyo's retirement, Yoshiko won Stardom's top title, the World of Stardom Championship, in August 2014.
Yoshiko's reign ended in controversy in February 2015, when she went off script during a match with Act Yasukawa, legitimately beating and injuring her, which caused an international scandal. Yoshiko was stripped of the World of Stardom Championship, suspended from the promotion and eventually announced her retirement. However, she soon returned to professional wrestling, and in February 2016, began working for Stardom co-founder Nanae Takahashi's new promotion SEAdLINNNG. She later made a special appearance at the 2021 Stardom event All Star Dream Cinderella, in a match against Mayu Iwatani, but hasn't appeared since.
