After the Japanese edition of the novel was published, Arthur Golden was sued for breach of contract and defamation of character by Mineko Iwasaki, a retired geisha he had interviewed for background information while writing the novel. The plaintiff asserted that Golden had agreed to protect her anonymity if she told him about her life as a geisha, due to the traditional code of silence about their clients. However, Golden listed Iwasaki as a source in his acknowledgments for the novel, causing her to face a serious backlash, to the point of death threats. In his defence, Arthur Golden countered that he had tapes of his conversations with Iwasaki. Eventually, in 2003, Golden's publisher settled with Iwasaki out of court for an undisclosed sum of money.
Iwasaki later went on to write an autobiography, which shows a very different picture of twentieth-century geisha life than the one shown in Golden's novel. The book was published as Geisha, a Life in the U.S. and Geisha of Gion in the U.K.
