Toyama-style day care service was established in 2003, which declares that every center offers appropriate services for everyone, regardless of their age or disability, in a homelike atmosphere. General intent of this research firstly lies in establishing a overview of the current conditions of these centers in Toyama Prefecture through questionnaires. Moreover, through an observation survey analysis, users' social behaviors in centers are sorted. Results are as follows: 1) Centers mainly offer day care service to the elderly while it's policy is “care for everyone”; 2) Not only newly built but old buildings were used. While staff office/kitchen is seemingly connected to the main common space in both types, some have difficulties to observe users because of the layout of rooms or furniture; 3) As easiness of entry into and staying at public spaces relates with users' behaviors, planning of room layout and furniture arrangement should be considered for Toyama-style day care centers; 4) Expressions of users' behaviors widely vary with users' disabilities and characteristics so that relationship between their behaviors and space composition was hardly found.
