Masatō Ibu (伊武雅刀,Ibu Masatō?) is a Japanese actor and seiyu. He was known as Masayuki Ibu (伊武雅之,Ibu Masayuki?) from Space Battleship Yamato until Space Battleship Yamato III. Yō Inoue convinced him to change the kanji 之 (yuki) to 刀 (tō) because she thought his name should end with a two stroke kanji.
