Education

Dr. Hanawa holds two academic degrees: a Bachelor of Medicine from Kagoshima University (2014), and a Bachelor of Agro-Biological Resource Sciences from the University of Tsukuba (2005). His educational journey combines both life sciences and clinical medicine, giving him a well-rounded background for psychiatric practice and biomedical research. His first academic pursuit in agro-biological sciences laid the groundwork for understanding environmental and physiological interactions, which he later integrated with human mental health and neurological science. Following his medical graduation, he embarked on a rigorous residency and clinical career in psychiatry while enrolling in advanced doctoral studies at Showa Medical University Graduate School of Medicine. This path reflects his dedication to both evidence-based medicine and academic development. Currently, his doctoral studies focus on deepening his research in neuropsychiatry and advancing mental health care models in Japan.

work Experience

Dr. Hanawa’s professional career in psychiatry began in 2014 at Niizashiki Central General Hospital, Saitama, where he worked as a resident doctor. From 2016 onward, he served at Showa University Karasuyama Hospital, Tokyo, in the Department of Neuropsychiatry. His experience spans both acute and chronic psychiatric care, with key responsibilities in clinical diagnosis, psychopharmacological treatment, and patient rehabilitation. Between 2017 and 2018, and again from 2024 to 2025, he worked at Showa University Northern Yokohama Hospital, Kanagawa, in the Department of Mental Care Center, broadening his expertise in hospital-based mental health services. In 2025, he returned to Karasuyama Hospital as a leading psychiatrist, where he continues to serve. Alongside his clinical work, he is actively pursuing his doctoral research in psychiatry. His interdisciplinary and multi-institutional experience makes him a valued contributor in both academic and healthcare environments.

Research Focus

Dr. Hanawa’s current research focuses on neuropsychiatric disorders, with a particular interest in the clinical pathways and diagnostic complexity of central nervous system tumors in adolescents, mental health in occupational settings, and innovative therapeutic approaches for severe psychiatric conditions. He investigates the interface between neurology and psychiatry, aiming to develop targeted treatment modalities through biomarker analysis, neuroimaging, and epidemiological mapping. He is also involved in protocol design for pediatric congenital craniofacial disorder biobanks, examining how structural abnormalities affect neurodevelopment and psychiatric outcomes. His interdisciplinary research bridges clinical psychiatry, epidemiology, and translational neuroscience, contributing to personalized medicine initiatives in Japan. Through his doctoral work at Showa Medical University, he is shaping the future of integrated mental health strategies and evidence-based neuropsychiatric care.

Conclusion

While Dr. Yoichi Hanawa exhibits solid clinical credentials and academic commitment, he may not currently meet the competitive research standards required for the Research for Best Researcher Award. His transition to research via PhD studies is promising, but he should focus on:

Publishing peer-reviewed research,
Participating in academic conferences,
Leading or joining collaborative research projects.

Recommendation: Consider nominating him for a Clinical Excellence Award, Emerging Psychiatric Researcher Award, or Early Career Mental Health Recognition, until a stronger research portfolio is built.
