Tobizaru Masaya (翔猿 正也, born April 24, 1992, as Masaya Iwasaki (岩﨑 正也, Iwasaki Masaya)) is a professional sumo wrestler from Japan and wrestles for Oitekaze stable. He made his top division debut in September 2020 and his san'yaku debut in November 2022. As of August 2023, Tobizaru is also the smallest makuuchi wrestler and the third smallest sekitori-ranked wrestler overall. He is the brother of retired wrestler Hidenoumi of the Kise stable; they became the 18th pair of sekitori brothers in sumo history. Despite the fact that they are in different stables, Tobizaru will not face him in competition as Japan Sumo Association rules prevent close relatives from being matched against each other outside of playoff bouts.
