Yori Moriarty took up tattooing in 2000 and, in 2005, began producing Japanese tattoos alongside American artist Jason Kundell. He took his first trip to Japan in 2007 and established contact with its tattoo culture through Osakan tattooist Horitoshi Izumi, in whose studio he worked between 2008 and 2011 over repeat visits that he combined with work as a visiting artist at Everlasting Tattoo in San Francisco, MVL in Leeds and Legacy Tattoo in Helsinki. He has participated in numerous conventions throughout Europe and the United States.
