"IntroductionRecently in Japan, there are many man-made public spaces planned and designed, especially in the center of cities, for example, "Roppongi Hills" and "Siodome Siosaito" in Tokyo, "Canal City" in Fukuoka, all of them large scale redevelopment areas. Some projects are reported on TV or magazines, so people seem to be interested in architecture and urban design. Even if urban design is appropriate, all designed projects are not "place for people (being in place)", because their projects not altogether appropriate, (e.g. middle aged "noisy" women take souvenir pictures, a singer with back-band make a noisy loud voice). Sometimes, we can see impressive and lively scene with person in urban public space. However, there are few vocabularies to express for the way of being impressive and lively in place and the relationship with the person. The aim of this study is to catch the structure of people's thoughts, "impressive" scene with person in city, and consider their person-environment relationship. MethodThe method of this study is questionnaire for collaborators (they are about twenty years old).The questions are three blocks: Ö^ "Please take a photograph your impressive scene with person in city", Ö_ "Please explain this scene's person-environment relationship(e.g. with others, place and city)", Ö` "What impression do you have on site ?"The number of response is four hundreds twenty-five.
