Trans depathologisation and gender identity disorder in Japan: A critical discourse analysis of medical literature, 2010-2022.

ABSTRACT

Since the depathologisation movement in 2007 to challenge the pathologisation of trans identities in Western psychiatry, significant developments have occurred, including revisions to Standards of Care and diagnostic criteria such as ICD-11's gender incongruence and DSM-5's gender dysphoria, acknowledging gender diversity as an expected part of human development. This paper argues that Japanese medical models reflect global issues but also have unique aspects shaped by cultural and linguistic nuances. Using critical discourse analysis, this paper examines how depathologisation discourses are perceived in the Japanese medical community, focusing on the term seidouitsusei-syogai (gender identity disorder), presenting three ways in which seidouitsusei-syogai is used psychiatric disorder, syogai/sikkan (impairment/disability/disorder), and diagnostic category. These uses are influenced by legal and social reforms, healthcare access and alignment with international classifications, while the medical profession's authority remains unexamined. Reflecting the structural challenges of diagnostic models in trans medicine, the interpretation of seidouitsusei-syogai differs from the English phrase 'gender identity disorder' due to the specific connotations of syogai in the Japanese context. By examining Japan's approach to depathologisation and medicalisation, this paper enriches the understanding of trans medicine and the impact of depathologisation discourse in Japan.
