SAITAMA NEUROPSYCHIATRIC INSTITUTE

What SAITAMA NEUROPSYCHIATRIC INSTITUTE does

Saitama Neuropsychiatric Institute (legal entity: Social Welfare Corporation Synapse, 埼玉精神神経センター) is a specialized neuropsychiatric medical institution headquartered in Saitama City, Saitama Prefecture, Japan, operating 357 inpatient beds (116 neurology, 241 psychiatric) across multiple ward types including psychiatric super-emergency, acute neurology/NICU, chronic psychiatric, and special disease wards. The institution is structured as a Japanese social welfare corporation (社会福祉法人) and traces its origins to 1953, having been reorganized under its current legal form in April 2011; its core departments include neurology, psychiatry, dentistry, rehabilitation, and radiology, supplemented by specialized outpatient clinics for memory disorders and headache, MRI/CT/bone density imaging, and an in-house clinical trial program. The center was the first site in Saitama Prefecture to administer lecanemab for Alzheimer's disease (initiated January 2024, with 191 patients dosed as of June 2026) and houses the Saitama International Headache Center, which serves as the Japan Headache Society Secretariat.

Revenue is generated primarily through Japan's national health insurance fee schedule across outpatient and inpatient services, supplemented by Saitama City-commissioned public health programs (Dementia Disease Medical Center since 2009, Dementia-Friendly City Planning Center since July 2024), long-term care insurance-billed welfare subsidiary operations including the co-located Nursing Villa Yono special elderly nursing home, Visiting Nursing Station, Moegi psychiatric day/night care, and Yono Honmachi Day Service. The institution runs an active community health education program (dementia supporter training, brain health festival, headache classroom sessions) and conducts investigator-initiated clinical research, including a joint project with Nagoya University on AI-based quantification of mild cognitive impairment using wearable sensors and ECG analysis. Leadership transitioned in April 2026 with Sakiyama Yoshio appointed as hospital director, while founder Chairman Maruki Yuichi retained governance and physician roles; the center has 251-500 employees and no disclosed external investors, functioning as an independent non-profit under Japanese welfare law.
