One of the survey methods used in architectural planning research is the behavioral observation survey, wherein, normally, observers are not treated as subjects of consideration. However, it has been indicated that descriptions in the Japanese language are inseparable from observers. Further, this applies to descriptions of behavioral observation surveys. In architectural planning research, Ikata (mode of being) focuses on this area. With reference to Japanese grammatical theories, this study (1) reconfirms the significance of Ikata from the aspect of observers, and (2) discusses how spatiality depicted by observers can be read from descriptions of results of behavioral observation surveys.
