Tea ceremony room is the architecture built for tea ceremony. Because of the awareness of the floor surface by the host and guests, we focus on the spatial region that a guest recognizes as the space of his own, space of other guests and solidarity space, we define this spatial region as the region. In this research, we try to clarify the changes and characteristics on the region of guests and the host and the one shared by guests during a tea ceremony.
We defined that when an individual is situated in tea ceremony room, the region that can be considered as belong to that individual as “personal space”, the regions around other guests as “other’s personal spaces” and regions with solidarity as “solidarity space”. We hypothesize that these kinds of region will be changed during thick tea and thin tea with certain relationship. We also defined that personal space, other’s personal space and solidarity space as “regional recognition”. In this research, to clarify the changes of regional cognition and the ways space is felt, the field research below is commenced. 1.SD(semantic differentiation) method psychological experiment to figuring out what cognition would tea ceremony and space would provide to guests.2.Regional cognition experiment to figuring out the changes of personal space, other’s personal space and solidarity space, also the tendency of reginal cognition.3.Testees are also asked to write down the items that influenced the evaluations of tea ceremony and the space.By analyzing the regional cognition diagram, the evaluation of tea ceremony and the space, and the psychological quantities, some characteristics of territorial cognition and spatial consciousness were clarified. During the tea ceremony, spatial factor, richness factor and impression factor become larger from enter to exit in both thick tea and thin tea, at the same time the solidarity space enlarged indicating the rise of feeling of solidarity. The area of solidarity space becomes biggest in the middle time when the tea behavior of passing the dessert among guests happens. The personal space tends to expand to the space that unoccupied by the different types of tea ceremony room in both thick tea and thin tea. 1). The common characteristics in different types of tea ceremony are listed below: According to regional cognition diagram, in thick tea, the solidarity space tends to connect to all guests in exit time. In thin tea, no limitation for conversation influencing the solidarity space connect to the guests who are neighbor to each other. The ways of connection of solidarity space are different in different type of tea ceremony room in both thick tea and thin tea. According to the area of region, the personal space stays almost unchanged from enter to exit time in both thick tea and thin tea. Other’s personal space becomes bigger at exit than enter time in both thick tea and thin tea. Solidarity space becomes biggest at middle and smaller at exit comparing with middle approximately. 2). The most influential factor in territory recognition is "delivery of tea and sweets" for both thick and thin tea. 3). The common psychological factors that change simultaneously among thick tea and thin tea, are spatial factor, variability factor, richness factor and impression factor, while comfortable factor, tension factor and peculiarity factor change differently.
