Kitousei-Seishinbyo(psychosis induced by invocation), initially conceptualized by Masatake Morita, was subsequently identified in various regions across Japan. Over time, it evolved into a broader field of “Possession research,” encompassing investigations into phenomena such as personality transformation and altered states of consciousness. More recently, new psychosocial triggers have emerged, including self-improvement seminars and newly formed religious organizations. Despite this shift, the frequency of reports of possession-related episodes has declined as scientific rational thought has advanced, and accordingly, the volume of academic research and publications on the subject has also decreased. In terms of treatment, there have been cases suggesting that psychotherapy can be particularly challenging, owing to blurred boundaries between self and others or inherent psychological vulnerability, thereby highlighting the necessity for continued scrutiny.During our clinical experience, we encountered a noteworthy case of psychosis induced by invocation involving a patient who developed personality transformation and delusional beliefs of possession after contacting a medium, ultimately leading to hospitalization. Nevertheless, we found that addressing practical life challenges and implementing behaviorally oriented treatment strategies yielded significant improvements. Drawing upon previous studies, we offer some preliminary thoughts on therapeutic approaches to prayer-induced psychosis, which remain imperative for contemporary mental health practice.As part of our presentation, we have tried safeguarding the patient’s identity and personal details. Written informed consent was obtained to ensure confidentiality and respect for privacy throughout the study and its subsequent dissemination. We hope that this report contributes to a deeper understanding of prayer-induced psychosis and stimulates further exploration into efficacious therapeutic modalities for individuals affected by this condition. In psychiatric treatment, in addition to basic treatments such as medication and psychotherapy, it goes without saying that attention must be paid to family and social aspects. This presentation on Kitousei-Seishinbyo is one such therapeutic perspective.
