Hirohisa Ienaga (born 1964) was a Japanese yakuza who was affiliated with the Goryu-kai subsidiary of the Omi Alliance in Osaka during the 2000s. On 16 December 2006, he and several of Ryuji Goda's minions attempted to beat down Kazuma Kiryu after Kiryu insultingly called Ryuji by his despised nickname, "the Dragon of Kansai", but, when Ienaga charged at Kiryu, Kiryu threw him over the balcony and down onto the piano on the main stage, terrifying the club's patrons.
