[Refereed] This study is to illustrate thought on regionality from the point of view of space composition in design theories on Public Hall by contemporary Japanese architects, Through the investigation of their published articles after the Second World War. Public Hall is important to local communities as "open regionalism facilities". After the Great East Japan Earthquake, The designers of public architecture need to think for the local community. Recently, Public architecture was developed every major application (Building types). So, The thinking about the relationship between architecture and regions is the most important for the contemporary Japanese architects. Therefore, this report were described about the thinking of relationship between architecture and regions on design theories on Public Hall. Further after this paper, the some design theories of several building types (Public Museum, Public Theater, Public Hall, Public Library, etc.) are going to be compared.<br> Firstly, the contents each design theory on Public Hall were analyzed, and several descriptions of “The subject” were extracted (Fig. 1). Next, the meaning of these comments was analyzed by applying the method created by Jiro Kawakita. Then, there were drawn a relationship diagram and 5 groups of meaning were found (Fig. 2). Next, those meanings were divided into two different groups (Fig. 2) ; “Phenomenon value” and “Physical value”. Then, the change of that relationship in terms of time was analyzed (Table 1).<br> Secondly, the contents each design theory were analyzed again, and several descriptions of “The Realization by space composition” were extracted. And the space compositions were analyzed. So, these were classified into 2 space compositions (Table 2); “Singular area” and “Plural areas”. Then Singular area was classified into 3 areas; “Inside”, “Exterior” and “Outside”. So Plural areas were classified into 2 areas; “In site” and “Out site”. “In site” is things that have no relationship with “Out site”. “Out site” is things that have relationship with “Out site”. Furthermore each Plural areas were classified into 2 areas more ; “Adjacency” and “Non-adjacency”. As a result, “Plural areas” is the most large (Table 2). Then, the change of that relationship in terms of time was considered (Table 3).<br> Finally, Between “The subject” and “The Realization by space composition” were analyzed (Table 4). Then, Relationships of “Phenomenon value and Plural areas” are large. Next, from the detailed analysis, 3 Patterns were found (Table 5). (1) The subjects with Phenomenon value, “Base of a group activity - Creation of much activity” and “Free space - Opening to a citizen”, are represented by “In site-Adjacency”. (2) The subjects with Phenomenon value, “Construction of the community - Solution to social problem”, are represented by “Exterior”. (3) The subjects with Physical value, “Continuation with the natural scenery”, are represented by relationship by “Out site-Non-adjacency”. Further, the change of that relationship in terms of time was considered (Table 6). So, The thought on regionality of the designers of Public Hall has changed from around 2000.<br> Consequently, a definite meaning about thought on regionality in design theories on Public Hall was found. In this particular study, we have pointed out the design ideas of contemporary Japanese architects about public architecture after Second World War.
