In the autumn of 1929, a Kyôto-based journal for popular medicine reported that the dean of sexology, Habuto Eiji, had committed suicide after having suffered from neurasthenia (shinkei suijaku) for a long time. A practicing gynaecologist, Habuto had been the editor of the sexological journal Seiyoku to Jinsei (Sexual Desire and Humankind), the author of numerous books on sexual issues, and the co-author, together with Sawada Junjirô, of an abridged Japanese version of Richard von Krafft-Ebing's Psychopathia Sexualis, entitled Hentai Seiyokuron (1915). He also was involved in the translation of Havelock Ellis's Studies in the Psychology of Sex (1901–1928), the twenty Japanese-language volumes which were advertised under the title Sei no Shinri as early as in 1927. Among other sexologists, Habuto had been a chief theorist on the causes of neurasthenia. Physicians, psychiatrists, psychologists, pedagogues, and sexologists agreed with him that neurasthenia primarily afflicted men and was caused by overpowering exhaustion that was in turn the result of certain sexual practices. Modern commentators like Habuto speculated that neurasthenia was the result of masturbation or – even worse – homosexuality.
