Hanatarash was notorious for its dangerous live shows. Some of the band's most infamous shows included Eye cutting a dead cat in half with a machete, strapping a circular saw to his back and almost cutting his leg off, and destroying part of a venue with a backhoe bulldozer by driving it through the back wall and onto the stage.
At a 1985 show in Tokyo's Superloft, the audience was required to fill out waivers due to the possibility of harm caused by the show. The show was stopped due to Eye preparing to throw a lit molotov cocktail onto the stage. The performance cost ¥600,000 (approximately $6,000 US) in repairs.
