Ryosuke Kato (加藤良輔 Katō Ryōsuke), born on March 21, 1984, is a Japanese actor. He's headed by Bamboo Management. Previously he was part of a group called JACKJACK, but due to a scandal revolving around fellow member, Aoki Kenji, the group separated in October 31, 2007.
His first musical debut was with the TeniMyu productions. In it, he played St. Rudolph's Kisarazu Atsushi as a part of the first-generation cast. Afterwards, because the company endeavored to make a Rokkaku-centric musical, Kato was brought back to play Atsushi's twin, Kisarazu Ryo, who was part of the Rokkaku tennis team.
