She has been described in Japan as "the queen of iyamisu."Iyamisu (eww mystery) is a subgenre of mystery fiction which deals with grisly episodes and the dark side of human nature. Readers blurt out "eww" when they are reading iyamisu novels. The term was created in 2006 by the mystery critic Aoi Shimotsuki. There has been an iyamisu boom in Japan since around 2012. Kanae Minato, Mahokaru Numata and Yukiko Mari are regarded as representatives of the genre in Japan. The back cover blurb of the Japanese edition of Gone Girl, published in June 2013, was "One of the best iyamisu novels from overseas."
