Yujiro Shirakawa (白川 裕二郎, Shirakawa Yūjirō, born December 11, 1976, in Kōhoku-ku, Yokohama, Kanagawa Prefecture, Japan)[1] is a Japanese actor and singer who is represented by the talent agency, G.P.R.
Shirakawa began his public career as a professional sumo wrestler (rikishi). He decided to become a wrestler because he regularly watched sumo on TV with his parents and admired popular wrestlers of the time like Chiyonofuji.[2] He enrolled in Asahiyama stable and began his wrestling career by first wrestling under his real name of Shirakawa (白川) and then adopted the shikona, or ring name, Tsunanofuji (綱ノ富士), to pay homage to Chiyonofuji and to recall his dream of reaching the top of sumo.[2] At the time, he got early successes but recalls he never gained weight, "no matter how much [he] ate".[2] After a while, Shirakawa aggravated back problems that were already latent. He began to feel pain so severe that he couldn't even put on his mawashi without suffering. Since he could no longer fight or even train, he decided to retire in September 1996 (intai).
In 2002, Shirakawa debuted in Ninpu Sentai Hurricanger as Ikkou Kasumi / Kabuto Raiger. He contested with Shun Shioya which became the "Handsome Hero Boom". Shirakawa played a big brother in the series, but he actually has an older sister.
He was also active in stage as an actor. He is also the main vocal of the chorus group Junretsu.
Shirakawa, with Kohei Yamamoto, Nobuo Kyo, Ryuichiro Nishioka, and Yūsuke Tomoi, became a member of the clothes brand Anunnaki.
