Tokyo Metropolitan Institute for Geriatrics and Gerontology (TMIG) celebrated the 150th anniversary in 2022. We have been successful in promoting a primary policy of mental and physical well being in the pursuit of healthy life expectancy for all elderly, especially the most vulnerable.
The number one priority of community dwelling elderly's expectations for medical care is "effective therapy of age-related diseases" such as vascular disease, neoplasm, diabetes mellitus, respiratory disease, orthopedic disease and sensory impairment, which are known to be a top 20 risks for deteriorate healthy life expectancy in coming 20 years. We will focus on these diseases more vigorously.
Further, by establishing close relationship with medical and social welfare resources, we will deliver seamless services for better QOL after acute care, introducing our own ambulance and remote-medical information and reservation system (C@RNA).
We have started three strategical projects for preparing peak wave of super-aged society to prevent ADL-threatening conditions represented by 1) dementia, 2) frailty, and 3) education as follows,

1) Integrated Research Initiative for Living Well with Dementia (IRIDE)
To create
# Tokyo Integrated Cohort for risk reduction of dementia
# Innovative seeds of disease modifying therapy based on new mechanistic survey
# Original biomarkers of blood, sensory and neuroimaging.
# Biobank of resources such as Blood, CSF and Brain.
# Evidence-based non-pharmacological therapy for memory and/or BPSD
# Community resource repositioning to prevent isolation

2) Center for Comprehensive Care and Research on Prefrailty (CRP)

To create
# Elucidation for mechanism underlying the effect of exercise
# Elucidation for mechanism underlying the effect of nutrition on muscle, bone and brain
# Original biomarkers of frailty in the blood, sensory and neuroimaging.
# E-Frail information trans-department network and one-stop therapy and care

3) Innovative Comprehensive Multidisciplinary Education (I COME)

To promote
# e-Educational System of dementia for citizens including islanders
# Multidisciplinary educational system of frailty for medical professionals and municipality staffs
# Awareness to living well with dementia and frailty for citizens of Tokyo Metropolitan

We will go forwards to obtain a steady fruit by sustainable efforts of all staffs in the hospital and the research institute of TMIG.
To complete the mile stones in coming 5 years, we absolutely need a new building for institution because of ever increasing the mission from Tokyo Metropolitan as well as rooms for doubled staffs. 
We would appreciate your support.

The motto of the Tokyo Metropolitan Institute for Geriatrics and Gerontology is to achieve"medicine with which patients and their families are pleased". Our hospital has been focusing on the treatment of cardiovascular disease (stroke, cardiac disease, aortic disease, and peripheral arterial disease), cancer, dementia and diabetes, which are closely related to emergency issues commonly seen in older adults. While these four pillars are our most important specialties, we also provide advanced medical care for common diseases in older people including bone/joint diseases, renal diseases, sensory disorders (cataracts and deafness)and lung diseases. Our hospital has been taking an active role focusing on advanced and specialized medical care for older adults, while developing a community health care model in the secondary medicine zone of the northwestern area of Tokyo, which has a population of 2 million. In addition, as an advanced medical center specialized in geriatrics, we will constantly confirm how advanced and cutting-edge medical care can be provided to older patients and what results can be obtained as a result of providing cutting-edge medical care. Furthermore, we believe that it is our important mission to open up a "healthy and happy" future for older adults by developing minimally invasive medical care that is friendly to older patients as much as possible.

In light of our origin as "Youiku-in" that was established in 1872, our center has played an important role in the welfare and medicine for older adults in Japan for more than 150 years. Accordingly, we should continue our steady efforts to be the leading hospital and research institute that proactively locate the problems within the aged society and progressively find solutions to create a better tomorrow for our patients and citizen of Tokyo.

Basic Principles

The Tokyo Metropolitan Geriatric Hospital and Institute of Gerontology plays a part in the creation of the urban model of a super-aged society in metropolitan Tokyo with the aim to achieve healthy long life through health promotion for the elderly. To this point we will provide appropriate medical care in accordance with the characteristics of the mental and physical conditions of the elderly, coordinate research and clinical practice, and conduct research to maintain and improve the QOL of the elderly.

Hospital Missions

As our aging society rapidly progresses, the medical need for the elderly has become increasingly diverse. As a specialized medical institution for the elderly, Tokyo Metropolitan Geriatric Hospital and Institute of Gerontology is working to enhance its function.
While honoring the policy of the Tokyo Metropolitan Government, including the health and medical care plan, we are strengthening our "vascular diseases care," "cancer care for the elderly," and "dementia medical care" as our focused areas, as well as emergency medical care and the promotion of community cooperation, in order to contribute to the maintenance and promotion of health of the elderly as one of the hospitals responsible for the acute care of the elderly

  • Taking advantage of the benefits of integration of research and medical care, we provide highly-advanced vascular diseases medical care, cancer care for the elderly, and dementia medical care.
  • We promote appropriate inpatient treatment planning and discharge support in accordance with the disease states and symptoms of each individual patient.
  • As a secondary emergency medical institution, we prepare emergency protocol to ensure the safety of local citizens.

The Tokyo Metropolitan Geriatric Hospital and Institute of Gerontology was established in 1872, a historical institution which was originally founded as a "sanatorium". It was re-established in 1972 as facilities for the elderly population including the hospital for the elderly, the Institute of Gerontology, open to any Tokyo resident. It has since stayed one step ahead in dealing with the aging society of today.
In 2009, the Tokyo Metropolitan Geriatric Hospital and Institute of Gerontology started operations as a local independent administrative agency which integrates a research institute and a hospital. In spring of 2013, a new facility was constructed, evolving in response to the social needs of the era.
