After writing several classic puzzle stories, Rampo soon turned to stories of the grotesque and horror (Saito, 49). Rampo became a popular writer outside of Shinseinen by serializing sensational crime fictions in a major newspaper (Ibid). He thus failed to meet the Shinseinen editor’s expectation to develop the genre into the literature of scientific rationalism (Saito, 64). Here is one story, ”Panorama tō kitan” (「パノラマ島奇譚」; English: “Strange Tale of Panorama Island”), which exemplifies Rampo’s ero-guro-nansensu taste . From this period, Rampo was attacked by social critics of producing “unhealthy” (fukenzen; 不健全) Japanese literature  characterized by its grotesque taste, lack of scientificity/logic, and “backward” premodern references, which is deviated from the scientific and analytic spirit—that is, the Golden Age puzzle formula of “whodunit.”Footnote:
For a well-rounded analysis of Rampo’s relationship with ero-guro-nansensu (エロ・グロ・ナンセンス) movement, see: Driscoll, Mark W. “Erotic Empire, Grotesque Empire: Work and Text in Japan’s Imperial Modernism.” Ph.D. Dissertation. Cornell University, 2000.
 One prominent figure that harshly criticized Rampo is Hirabayashi Hatsunosuke (平林初之輔), who was a firm proponent of scientific civilization.
