Marianna Association

What Marianna Association does

Marianna Association (一般財団法人聖マリアンナ会), operating Toyoko Keiai Hospital (東横惠愛病院), is a non-profit foundation that runs a 297-bed psychiatric specialty hospital located in Miyamae Ward, Kawasaki City, Kanagawa Prefecture, Japan. Founded in 1941 as Toko Hospital and rebranded under its current name in 1999, the hospital has provided continuous psychiatric care for over 80 years to the Kawasaki/Chubu region, serving children, adolescents, adults, and elderly patients across six wards (acute closed wards by gender, mixed-gender recuperation ward, child-adolescent ward, and elderly/dementia ward).

The hospital operates a full continuum-of-care model spanning outpatient psychiatric and psychosomatic consultations, child-adolescent and second-opinion specialty clinics, inpatient psychiatric care, psychiatric occupational therapy across four dedicated OT rooms, clinical psychology counseling (individual, play therapy, group therapy), nutritional and pharmaceutical guidance, large-scale psychiatric day care (weekdays 8:30-15:00), and psychiatric home-visit nursing plus home-visit medical treatment covering Kawasaki City wards and parts of Yokohama. Core technology comprises standard diagnostic equipment (CT, MRI, ECG, blood/urinalysis, psychological testing) deployed within an Electronic Medical Records-based team-care model integrating psychiatrists, certified psychiatric nurses, psychiatric social workers, clinical psychologists, occupational therapists, pharmacists, and nutritional therapists. A distinct feature is the embedded Kawasaki City Central Support School visiting classes within the child-adolescent ward (since 2015), enabling educational continuity during inpatient stays.

Revenue is generated primarily through Japan's national health insurance and 自立支援医療 (independent support medical care) reimbursement for inpatient and outpatient services, supplemented by self-pay offerings including a ¥30,000 second-opinion consultation, ¥5,000-7,000 individual counseling sessions, ¥1,000-3,000 group therapy, ¥1,000-5,000 psychological testing, and day care fees of ¥820-2,460 per session depending on insurance type and tenure. The hospital sustains approximately 300 staff (including ~111 nursing staff), achieves ~100 outpatient consultations daily across four examination rooms, and manages 25-30 inpatients per doctor. Distribution is driven by a regional medical cooperation network of over 100 partner clinics, hospitals, and welfare facilities rather than direct consumer marketing, with patient acquisition primarily through referrals, walk-in general psychiatry visits, and institutional outreach via nursing department visiting lectures.
