Group-living for people with dementia in JAPAN Group living … S mall collective residential facilities H omelike atmosphere and high quality of care A lternative form to the traditional institutions Increasing from mid of 1990s Over 5,000 places in Japan and 45,000 people living Regulated as a place for dementia with 5 to 9 residents

PURPOSE of STUDY (1)Illustrating the living environment of people with dementia (2)Considering relation between living in group-living and the surrounding environmental factors with viewpoint of four year’s longitudinal survey (3)Space usage and the change Keyword: CHANGE, ADAPTATION, SPACE USAGE, DEMENTIA

SUBJECT of THIS STUDY --Group-living “Komorebi-no-ie” Sunlight Filtering Home -- Opened in April Japanese style one-storied wooden housing -- It has high quality spaces -- Harmonizing western design theory and Japanese taste well -- One of the advanced model of group living in Japan REF: IAPS in 1998, Prof. Toyama, Environment-behavior study in a dementia care facilities

RESULTS (1)Space usage is not uniform and stable. (2)Several factors bring changes of living. (3)Longitudinal and continuous survey can cover the changes and tell the life of group living and dementia.

Longitudinal survey is very useful to show the various patterns of living and the changing, and understanding of place for dementia.
